March 3 4:06 pm

New entry in the Issues and fault finding page

5.2 The system doesn't detect small tap-in putts.

Probably causes

1. The ball wasn't detected leaving the launch zone area.

2. The ball didn't attain the minimum ball speed for a putt or shot

Even though the system maybe in "Putting Mode" so that the camera frame rate is reduced,

this reduction in frame rate may still not be sufficient to see the ball leaving the launch zone area.

A solution would be to place the ball very close to the forward edge of the launch zone area when attempting a tap-in putt.

Generally speaking - and to the best of our knowledge - no overhead camera tracking system can detect a 4 inch or so tap-in putt.

(and certainly no radar system can - which at the best of times can't even detect a regular putt let alone a tap in putt)

Reason is because no system can differentiate between the player intentionally playing (i.e. tapping) the ball

and not just repositioning the ball on the mat with a club or foot if the ball is not seen to have left the launch zone area.

March 3 9:45 am

LX2 gets additional upper lighting bank, on/off switch and USB ports

March 3 8:45 am

How the Floor GS (Grey Scale) setting effects the brightness/contrast setting.

If your lighting is insufficient to illuminate the ball so that it is detected when using fast shutter speeds,

you will have to increase the Brightness/Contrast level.

In so doing, you may find that only the center of the ball is showing an increase in brightness.

This is because the brightness procedure is only increasing the brightness of pixels that have a GS above the floor GS level.

The idea is to only increase the brightness of the ball itself and not the surrounding floor so that a stronger contrast is made between the ball and the floor.

It is thus important that the Floor GS setting is set closer to the actual floor gray scale in order to increase the brightness of the complete ball.


March 2 2:36 pm

CP V 10.0.6.4

Fix: Occasional false error message being shown in camera panel stating:

"Error: Floor GS setting of - is lower than dark trigger pixel. System won't function"

Line Drawing

New: Line Drawing for Club and Ball data verification including AOA.

Users can now draw lines on the shot ball and club images to measure any angles and distances.

More about Lenses and color cameras

Results of color camera VS mono camera comparisons with exposure time set to just 100 us.

1. Of interest was the apparent increase in image brightness when using a color camera compared to a monochrome camera

2. A better (less grainy) method of converting a color camera to mono is to switch the Monochrome Mode on in the Huateng App in the color cameras Color Process

Then set the new "Set Color Cams to Mono cams" option ON in the System Setup panel.

VisTrak LX2 comparisons

While finishing off the new LX2 Compact assembly methods and features today, I thought I'd check out what the competition to this product would be.

Starting off with the Uneekor Mini (with a list price of a whopping $4,500) I viewed the review videos.

Expecting to see really nice shot video playbacks of the club making contact with the ball from the top camera showing club face angle and path,

I was shocked to see that no such video playback of the club face angle at impact to the ball or path is anywhere to be seen or featured in the videos.

Maybe I'm missing something here, but I'm astonished why people are raving about a system that costs over double the price of the LX2 ($2,299)

that doesn't even capture club face angle and path shot videos from a top camera.

February 20 1:35 pm

CP V 10.0.5.6

Fix: Error in yesterday's valid shot check function causing putts and chips to not be recognized


February 18 6:08 pm

Coming this week:

February 18 12:42 am

CP V 10.0.5.4

New: Improved valid shot check

to prevent inadvertent ball launches when bending down to place the ball on the mat.


February 17 5:22 pm

Coming tomorrow: Improved valid shot check

to prevent inadvertent ball launches when bending down to place the ball on the mat.

Do not use soccer balls!

The system requires the ball to be predominately white and balls with large black soccer markings on them

cause the system to either not detect the ball at all or the ball is detected as too small.

February 17 1:45 pm

CP V 10.0.5.2

New: Virtual spin dots for testers - now showing dot positions on circumference plane and ball graphic side view

Virtual spin dots are used to test the spin detection method.

Press the V key on your keyboard to go to Virtual Dot Mode

Use arrow keys to move dots around on the ball

The dots can be moved around anywhere on the ball image and the resulting back and side spin rates - based on their co-ordinates - will be automatically shown.

Business news :

GSA Golf VisTrak systems going full commercial retail

VisTrak prices to increase by 33% later this year

Well, I guess it had to happen sooner or later.

i.e. if you can't beat em, join em.

Selling direct wholesale to customers is all very well and good but - it doing so - we don't get to reap the benefit of resellers advertising and pushing our products.

Consumers are very influenced by product advertising and exposure, so just selling direct, GSA Golf can't compete on this advertising and exposure front at that level.

At least, not without investing large sums in advertising.

So, while the decision to go commercial retail hurts me, I see no alternative if GSA Golf is to compete in this very competitive market.

In order to give resellers a decent incentive to advertise and push the GSA Golf VisTrak range, a significant markup (i.e. from 33% to 40% ) will have to be offered.

As such, all VisTrak launch monitor system prices will soon (this year) be significantly increased to allow for reseller markups.

February 12 2:25 pm

"Ball Spin Detection Theory" page updated.

 


February 9 6:35 pm

Coming over the next few days and weeks:

An in-depth analysis of the complexities and methods of detecting ball back and side spin

from an overhead mounted stereo camera system like the SCX

Using real customer shot videos,

all frames showing back and side spin rotation from the flying ball's spin dot patterns or ball logos on the ball will be in-depth analyzed and results shown.

February 9 4:50 pm

Even More about Lenses and IR light testing

As I was so impressed with the test purchase of the Computar M1214-MP2 C-Mount lens at the beginning of this week,

I went ahead and purchased a batch of 10 of these lenses for $1,390.

After all, what can go wrong eh?

Well, as it turns out, plenty can go wrong, as the new batch of the same lenses are not the same as the initial test lens purchased.

Probably the supplier of the lenses had an older model of the same lens in stock with the initial purchase and the newer lenses have changed.

While the newer lenses still have a produce an increase in brightness compared to the standard Marshall lenses,

it is not quite as much and focusing with IR light is not anywhere near as good.

Looks to me like the newer lenses have a coating on them that is meant more for visible light than IR light.


CP V 10.0.4.8

1. Accentuated valid ball spin dots

2. More tolerance with ball size checking

3. Possible issue with camera alignment fixed

4. A number of smaller cosmetic issues fixed

Next CP update with improved ball spin detection due this weekend


February 7 5:18 pm

V 10.0.4.7

Fix 1: Ball not being detected in launch zone when using the single camera VisTrak Eagle system

New 1. New customer camera registrations

New 2. When switching on "Show Carry" the displayed carry is now shown as "Estimated Carry" as the CP can't know what the course conditions are or what the terrain is in the game software.

New 3. Extended Ball detection now default OFF with EVi systems (too time consuming)

New 4. Min ball size reduced to 25 pixels for customers mounting the cameras higher than 9 ft

New 5. The incorrect Scaling warning is now shown in all frames that contain a ball image and which appears to be too large or too small.


February 6 4:05 pm

Improvements to the installation, calibration and fault finding pages

Next CP update due tomorrow


February 5 4:24 pm

They new Computar Lenses (that produce a significant increase in image brightness) are now being offered with all VisTrak systems now

Computar M1214-MP2 C-Mount 12mm Fixed Lens.

IR light testing

On second thoughts - and as the tests yesterday were so good with our standard 24 LED IR lights -

I don't think I will take the risk of purchasing this $659 IR Illuminator that is 10 times the price of our regular 24 LED IR illuminator.

Main reason: It's not made in China.

And if it's not made in China, then the price is usually 2 to 10 times the price for the same equivalent product made in the USA or in the EU.


February 4 1:50 pm

Even More Lens and IR light testing

-

-

Of course, adding more IR lights also improves image brightness.

Just adding 1 more CM Vision 24 LED IR light or 2 smaller satellite 12 LED IR lights makes a big of difference

Thus, all SCX IR systems will now include 2 smaller 12 LED IR satellite lights.

February 4 12:30 pm

More Lens and IR light testing

The above images were captured using only the standard IR lighting (3 x CM Vision 24 850nm) at a distance of 8ft but with the new Computar M1214 lens.

All in all, not that bad. Especially considering the low cost of these CM Vision IR lights.

Never-the-less, I will be purchasing the $659 10 degree Illuminar IR lights just to see if there's any substantial improvement.

Thus, the SCX IR will only be fitted with these lenses from now on.

More Lens comparisons

The new Computar lenses have arrived

Bloody hell! I stand corrected.

My yesterday's skepticism about the new Computar Lens not being as good as the old lens has proven me wrong.

They really are better.

So what does this mean?

Essentially it means that we can either reduce the exposure time down to 150 micro-seconds and thus eliminate motion blur

or

reduce the amount of lighting while leaving the exposure time at the standard 300 micro-seconds.

Note that the above images were only using 2 LED spot lights.

Either way, this is good.

On the negative side, these lenses cost $100 more than the regular Marshall or HT lenses, so these new lenses will be an optional extra for those that want them.

For those that would like to source their own new Computar lenses, search for:

Computar M1214-MP2 C-Mount 12mm Fixed Lens. Price around $130

an 8mm version is also available

New virtual ramp ball SCX calibration

This method places virtual balls on a virtual ramp to calibrate the SCX cameras. Thus a real ramp is no longer required.

Coming later this week.


January 20 5:06 pm

V 10.0.4.1

Fix 1: Sporadic incorrect ROI

I've been looking to fix this issue for ages now. I could finally reproduce the issue today and find the cause.

Quite a number have pointed out this issue to me, so I'm very pleased to have this fixed now.

Known issues:

Camera alignment setup still a bit finicky and SCX ramp calibration not yet completed.

Even after a good 9 hours of coding and testing today.

Fix should come tomorrow or on Monday.

While I like the ball rolling down a ramp method, there's a bit of drawback to it. Namely: the ball is accelerating.

This means the precision is good as it starts the roll down the ramp but quickly deteriorates as the ball roll picks up speed.

I'm thus testing a method that has the ball fixed on the ramp (with Velcro) at various evenly spaced distances or use a tilted card with pre-printed balls or squares on it.

Also coming up this next week:

Camera alignment for EVi and Eagle systems

1.New customer camera registrations

2. A number of smaller feature updates

3. The new SCX ramp calibration is now selectable but not yet active.

SCX ramp calibration should be ready later this weekend with full instructions.


January 16 3:00 pm

Is checkered board calibration real calibration?

-

In my opinion not. Just laying a checkered board flat on the floor (like others do) is only useful for camera alignment and possibly scaling.

Real calibration would require that the board be tilted up at a multitude of angles and multiple readings be taken.

Without that, the cameras would have to be mounted at designated and limited height.

The (up and coming) new SCX ramp calibration method allows the user to mount the cameras at any height and space the stereo cameras at any distance.

i.e. no matter what height the cameras are mounted at or what spacing the cameras have, the calibration will ensure a perfect match for accurate readings.

New super easy SCX calibration

Coming up this week : New easy SCX stereo camera calibration method.


January 15 4:00 pm

New Fault finding and Common Issues page


January 14 9:57 am

More Lens comparisons

Okay, so the new HT 2/3" lens came in but - while there is some brightness and clarity benefits - the brightness increase is still not as significant as with the Computar lens.

I'll be ordering a Computar 12mm 2/3" lens now and will publish the comparison results this coming week.


January 13 4:40 pm

Coming tomorrow: Brighter clearer images test with the newly arrived 2/3" camera sensor size lens

If this lens (from the camera manufacturer) works as well as the Computar lens (see below Jan 9 update), then I'll make it an official optional update.

New measured ball spin when putting without the requirement to ball markings.


January 4 8:37 am

V 10.0.3.5

Launch zone area height now limited to 120. Size is now launch zone width.

This is done so that players don't place the ball too near the top or bottom edge which will probably cause the shot not to be detected

due to the images of the ball in flight can too easily go out of the FOV of the camera

New Ball Spin detection using the ball logo

for overhead SCX and Eagle systems

You can now select the option "Spin line / Logo on ball" to measure ball spin for overhead camera systems (i.e. SCX and Eagle).

As the logo will not always be visible in the frames, the system now automatically scans for 2 adjacent fames showing the ball logo in all the 16 ball speed frames.

Improved ball spin detection.


December 25 1:42 pm

New Ball Spin Setup page


December 24 2:07 pm

SCX Ball Spin

While measuring ball spin from a side mounted camera like the LX and EV (GC2, GC3 etc) is comparatively easy

( as side mounted cameras see a complete 360 degree of rotation ),

measuring ball spin from overhead mounted cameras that can only see a small 17 degree of rotation is a whole new ball game.

As such, most work on the SCX system in the next few weeks will be aimed at increasing the SCX's ball spin and side spin detection accuracy.


December 23 12:49 pm

V 10.0.2.6

New 1: Z perspective correction for rear mounted SCX cameras

Currently all values set to zero though as it not yet clear what - if any - correction is required

Fix: Error in Z perspective correction for forward mounted SCX cameras

Ball co-ordinate CSV export feature in camera panel (Top-Right corner)

Numerous other smaller updates

SCX vs GC2

While the data calculations of the LX and EV systems vs GC2 worked out just fine,

we still have a bit of work with matching SCX data with the shot results of the GC2.

The above image shows a good match with the SCX cameras mounted 2 to 3ft behind the player - and thus not requiring perspective correction -

However, we are still working on tweaking the setup to get the results of the SCX data to match the GC2's results when the cameras are mounted forward.

Getting close though.

SCX rear mounting

You now have the option to mount the SCX cameras and lights ahead or behind the ball.

Pros for rear mounted cameras (like the Uneekor):

1. Little to no perspective correction required (thus possibly more accurate).

2. Unit can be mounted outside the enclosure.

3. Lighting not causing glare in the players eyes.

4. Cameras not going to be hit by very high lofted ball strikes

Cons: Less likely to view the front of the club face.


December 19 8:14 am

New SCX stereo camera ball speed and calibration

V 10.0.2.1

The new SCX ball speed calculation method is now implemented.

Switch the new stereo cam ball speed calculation and/or perspective correction OFF / ON in the Video panel

Note that perspective correction is only used if the SCX cameras are mounted 3ft ahead of the ball launch position

and not if mounted 3 ft behind.

New easier SCX calibration instructions are now on the SCX Installation page


December 17 2:20 pm

New SCX stereo camera calibration aims

The fundamental aim of the new SCX speed calculation methods and calibration is to ensure the SCX is as accurate as any other launch monitor on the market.

Independent tester Phil in the UK already proved that the EV/LX systems are almost spot on in comparison with his GC2.

We now need to do these comparison tests with the SCX.

While I don't expect the results will be quite as good as with the EV/LX, but they should be within a +/- 1 or 2 mph range

December 17 10:15 am

V 10.0.1.8

New SCX stereo camera calibration

New 1: Ball height off the ground is displayed

Users can use this to verify calibration.

i.e. when elevating a ball on the floor (e.g. placing the ball on a dark box of a known height)

a comparison can be made between the measured ball height and the actual height of the ball on the box.

New 2: When loading a shot video in an SCX system and the current camera offset is zero, then it will be assumed it is 125.

Coming up:

We're still testing the new SCX ball speed calculation methods and calibration. Expect many more updates regarding this over the next few days.

Current unknown: calculation accuracy when the system is in 1500 FPS mode.


December 16 2:24 pm

V 10.0.1.7

New SCX stereo camera calibration

The new SCX data calculation methods and calibration is still being tested but this version of the CP is optionally using the first version of the calibration.

Switch on / off in the Video panel.

Until further notice, stereo SCX cameras should be aimed so that the ball appears as close as possible to the center line when in Full Frame mode.


December 12 4:00 pm

New 1: Many smaller features and cosmetic updates

Fix 1: Shot video playback overlay not working when putting or chipping


November 24 11:48 am

V 9.9.9.4

New 1: Overhead camera perspective correction

The perspective correction is currently user definable in the Video panel.

Set the slider bar to zero for no correction.


November 20 3:42 pm

V 9.9.8.8

New 1: Update for customers using 2 color cameras

New 2: Auto color shot video detection when cameras not plugged in

Note: Frame rate will be around 260 fps lower if using 2 color cameras instead of 1 color and 1 mono.

When using 2 color cameras in 800 fps mode, frame rate is reduced to 540 fps

When using 2 color cameras in 1500 fps mode, frame rate is reduced to 1000 fps

New 3: Max shot video files

Currently the max number of shot files that are saved before looping back to 1, is 512

If using 2 color cameras with all the color frames, you will eat up over 200 gigabyte of disc space.

This new option will allow you to limit the video file count down to 8 video files

New 4: Measured frame rate now used in speed calculations

All speed calculations are now based on the real captured camera FPS and not just the hard coded 800 and 1500 fps

While the difference is minimal when not using color cameras, it can be substantial when using color cameras or the users PC can't handle the regular frame rate


November 5 1:26 pm

New 1. New Improved step by step installation instructions for SCX, LX2, Eagle and EVi systems on this website.

Also coming this next week:

Ball spin methods explained (with real ball spin photos) and user ball spin verification instructions.


October 29 3:15 pm

Measured ball spin

Intensive bench testing of the new measured ball spin detection methods using spin dot balls are currently underway.

Free measured ball spin software update release for EV and LX systems are due later this week

Free measured ball spin software update release for SCX systems due a couple of weeks later.

Note that using the ball logo as ball markings in side mounted camera systems (as in the LX and EV systems ) has 2 major number of disadvantages:

1. the user is required to bend down and place the ball on the mat with the logo facing the camera for every shot. (i.e. most will soon get tired of doing that for every shot)

2. Most ball logos are too small and faint to be detected with high speed cameras without additional Xenon flash lighting.


October 26 4:40 pm

V 9.9.7.2

New 1: Factory preset camera function assignments

This has been an issue for new users for some time now.

i.e. which camera in an SCX stereo system is the left camera and which is the right camera

or in an EV or LX system, which camera is the vertical camera and which is the horizontal camera.

This issue is now fixed. New users thus don't have to now test which is which and have to manually re-assign the cameras

New 2: Double frame capture

This feature is primarily only required when bench testing ball spin with a stationary spinning ball on a variable speed motor.

When selected, and a soft trigger is made, 2 frames will be captured (instead of one) at the real frame rate (i.e. either 800 or 1520 fps).

Testers can then see and measure the amount of rotation between frames and compare the spin rate results with those derived from tachometer readings


October 22 11:34 am

V 9.9.6.9

If using GSpro, TGC or E6 Connect, then an automatic connection to the game software will be made 8 seconds after the intial start of the CP (i.e. after all camera checks are made).


October 21 12:03 pm

V 9.9.6.8

New 1. Vastly improved camera ROI (Ball centering and positioning) methods

New 2. Error messages being shown if connection to game software (E6, GSPro, TGC etc) is not established

This has been done because some customers are not aware that the system won't function if the connection to the selected game software is not established

and thus unnecessary time consuming support is being provided.


October 19 4:14 pm

V 9.9.6.7

Auto camera FPS speed checks

New: Camera FPS speed checks are now performed when starting the CP.

If camera frame rate is below the minimum of 700 fps (regular fps is 800 to 1500 fps) then a large error message is displayed indicating a major error and that the system will not function correctly.


October 15 1:45 pm

V 9.9.6.4

Switching camera frame rate from 800 fps to 1500 fps

You can now switch the camera frame from 800 fps to 1500 fps in each camera for a combined frame rate of over 3000 fps !

Benefits: You'll see double the number of frames of the ball in flight in the shot video playback and ball spin can be measured.

Hi Martin, I just wanted to drop you a note to say how amazing the new VisTrak camera is.

I am still playing around with the settings and learning but the video capture and being able to see the frame by frame impact is awesome!

I also really like the way you show the ball ready/playback buttons as an overlay on the TGC.

The best part of my day is going to the tech page and seeing your latest updates - keep up the good work!

Richard L. Illinois 12/17/2020

Hi Martin- I wanted to let you know how much I appreciate your efforts.

I could have bought any of the expensive and well-known golf simulators, but I’m glad I ultimately took the chance and bought your products.

It wasn’t an easy decision, as it takes a leap of faith to take the road less traveled, but it has made all the difference.

I love that your products are not perfect (no one's are) but that you strive for perfection while pushing innovation.

You’re clearly never satisfied. As soon as you develop a new software feature, or build a new camera system, you're immediately back at it working on the next iteration.

You’re a true inventor and engineer. Almost every day I download the latest beta and see how it enhances the simulation.

It's like Christmas morning everyday.

Sometimes there’s a marked improvement. Sometimes the new feature “breaks” something else.

But over days and weeks, I feel how the collective innovations are improving the overall experience.

Your products aren’t for everyone but they are a clear alternative to the high-margin corporate products that have an arm's length association with their user base.

Buying a GSA product is buying into you and becoming part of your user community.

You listen, you care, and you explore. I know many of us appreciate it but perhaps not enough of us say thanks.

Martin, thank you for an enjoyable and rewarding journey with your products in 2020.

You’ve made a COVID 19 year more endurable.

Hello Martin, I have had 2 weeks of excellent play and stability in Eagle Mode! This has been very enjoyable! Matt T.

Matt T. 1/14/2021

Hi Martin, I see your daily updates on the Tech News page and I just want to say thank you for all your hard work and dedication.

Your passion for golf and engineering clearly shows and thank you!

Mike B. 05/03/2021

Thanks Martin……..

I appreciate the excellent customer service and fair pricing! And the very informative website!

Have a great day!

Mike.

Note that all GSA Golf software is written in the C++ programming language, which isn't particularly easy.

As they say, while it's easy to shoot yourself in the foot with the standard C language,

you can blow your whole leg off in C++. : )
