August 7 2018
Minimum ball speed reduction when in Chipping Mode now limited to 50% instead of 2.5% as number of customers reported ball distances when in chipping mode were only a couple of feet.
A remote support session showed that their chip ball speed reduction was set to 2.5%.
The "What's in the Box" page has been completely updated.
Lots more info and ideas on how to raise flooring on the flooring page.

CX Surround production
CX Surround assembly is starting this month.
First shipments going out on the 15th.
CX Surrounds will be using the new IBS image processing too.
CX Surround casing updates
Update 1. For a super cool look, the CX Surround will be using acrylic glass edge lighting at the front and back of the unit instead of individual LEDs.
Update 2. The entire front panel (facing down) is now entirely made of IR filter acrylic glass instead of cut-outs.
Update 3. For the moment at least, the wood sides are optional extras as the black anodized aluminum framing looks just great too.

USB over CAT5
There's a new wiring diagram for the PX5 system using USB over CAT cabling on the wiring page now
July 30 2018
New IBS - Image Background Suppression method
IBS has been significantly improved in this version of the CP.
The above test image shows a ball trace with a very bright background. Without IBS, the CP can't detect the ball trace. i.e. it picks up pixels in the background.
With IBS ON, the background is reduced in brightness to reveal the ball trace.

July 14 2018
Dual club tracking mats
The software update for those using a dual lane PX5 system is now complete.
The system automatically switches from left mat to right mat and vice versa when a left or right handed player is up.
New "Carry Adjustments" page
One of the most asked questions is how to adjust the carry distances in GSA Golf.
I've thus made an extra web page just for this.
July 11 2018
Fix for TGC sometimes not excepting shots
The fix for the above issue is now available in this CP update.
July 11 2018
TGC sometimes not excepting shots
We've noticed that TGC can sometimes seem to hang and not except shots.
We are currently seeking a solution to this problem with ProTee and a fix will be available shortly.
In the meantime, if you find that during a game TGC suddenly stops excepting shots, press the "ESC" key and select "Rewind shot" in TGC.
July 3 2018
Lens Hoods prevent lens ghosting
A retractable lens hood is now fitted to all new GSA Golf cameras that wil prevent lens ghosting from the overhead and floor mounted lights.
June 30 2018
All GSA Golf enclosures and full version simulators now include wood turf carpet transition trim and all frame tubing.

Golf simulator Lag times.
I've put a couple of YouTube links on my "Buying a golf simulator" advice page about this.
I know SkyTrack has a serious problem with this but I was surprised to see that a $50,000 Trackman system has a problem with this too.

Measuring ball spin using the ball's logo.
New logo matching end detection.
An issue with measuring ball spin using the ball's logo is that the correct matching ends of the logo must be detected in order to correctly measure the amount of rotation within the time frame..
i.e. if one end of the logo is found in image 1 then that same end has to found in image 2. Failing to do this can result in very different ball spin rate measurements.
The above two images show a ball spinning at a rate of 8321 rpm. We know this because the amount of rotation within the 2 ms frame delay was 149.78 degrees.
And we only know the correct amount of rotation because the Letter "C" in the Calloway logo has been detected correctly in both frames. This is shown by the two red cross hairs over the letter "C".
Without this new "Matching logo end detection" feature, the CP image processing may well get the ends mixed up and then a totally different amount of rotation will be measured
(i.e. 30.22 degrees here) and thus a totally different and false ball spin rate will be calculated. (Note that the two sets of images are from the same shot.)
As can be seen from the above two images, the letter "C" in the Calloway logo has not been detected in image 2 (i.e. there's a green cross hair on the "C" instead of a red cross hair).
And thus a false spin rate measurement was calculated (i.e. 1678 rpm instead of the real 8321 rpm).
It should be noted that not all ball logos have a dominant end and thus it may be required to use a black magic marker or black ink pen to accent one end of the logo.
Note that measuring ball spin using the logo (or any marked balls like those with A systems) is the only way a camera method of ball spin detection is able to do this in real time. i.e. without a long 2 to 4 second or so lag time (SkyTrak / GC2 etc).
While radar systems (Trackman, FlightScope etc) require metallic dots be applied to the ball and the ball be placed with the dot facing upwards.
June 15 2018
LX & Bcam ball spin calculation error now fixed
An error causing incorrect ball spin measurements was detected today in the LX and Bcam products.
The occasional error caused very high spin rates to be calculated (usually capped at 9999 rpm). This is now fixed in this update.
June 12 2018
CX Surround club tracking now implemented
Both the PX2 optical sensor club tracking and the CTS camera club tracking are now functioning with the CX Surround.
PX5 timing error
A timing error in the PX5 was causing occasional shots to be launched without club data. This is now fixed.
TGC stuck in putting mode issue
We are now checking the current surface lie and club type every 2 seconds in TGC. This fixed the problem.

Club wait count for PX5 users
The amount of time the CP should wait for the slower PX2 sensor mat data to arrive is now user adjustable from the main CP window.
Note that as the cameras are faster than the PX2 club tracking sensor mat, the CP has to wait a few milliseconds for the club data to arrive before launching the shot with just V and H cam ball data.
CX Surround putting
The putting is now working with the CX Surround.
Camera exposures should be set to around 7000 ms with the CX Surround instead of the usual 10,000 in the V and H cam setups in order to reduce the length of the ball traces with hi speed shots.
Error causing the shot data to be incorrectly measured when not in a camera window fixed.
CX Surround test screen shots
There's some test screen shots of the CX Surrounds images on the Surround page today.
The tests outline a faint trace issue that we expected.
May 31 2018
TGC auto connection update
If the TGC server is started but a game isn't running, the message "TGC Connected: Game not running" will be shown instead of "TGC not running".
Manual speed adjustment
When setting up the CP launch parameters manually to test a shot using just the mouse, you can now adjust ball speed in10mph steps by holding the shift key down.
May 30 2018
TGC auto connection update
The CP now automatically connects to TGC when TGC is started.
The CP now PINGs the TGC server every 10 seconds to see if the connection is still live.
If no response from the PING then a re-connect is automatically made.
TGC surface lie
The CP now picks up the current surface lie in TGC and displays it in the main window.
Last game software now stored
The CP now stores and retrieves the last game software used (i.e. TGC, E6 ,PP or GSA) and connects to them automatically.
May 10 2018
Hcam ball speed calculation speed control
When using the new Hcam launch feature for high lofted shots that are out of the FOV of the Vcam, you can now adjust the Hcam scaling factor and thus the ball speed for these shots.
Screen shot message appearing in screen shots
This is now fixed in this version of the CP
May 4 2018
CX Surround - Accuracy now within +/- 0.1 cm !
Using a correction and scaling table, we now have the stereoscopic cameras in the CX Surround detecting 3D ball positions in 3D space to within an accuracy of +/- 0.1 cm.
(Feels a bit here like working on the correction software that the Hubble telescopic had to undergo at the time it was first launched.)
April 28 2018
Hcam launch for high lofted shots that are out of the FOV of the Vcam
As it's possible that the ball trace with very high lofted shots will be out of the FOV of the Vcam camera, we've added a new feature that will allow the ball to launch with just the H cam data.
Switch this feature on or off in the Hcam window (lower right side of screen).
Note that this feature has 3 modes. 1. OFF, 2. only ON when in chipping mode, 3. Always ON
Default is 3. Always ON
When ON and a valid shot is detected in the Hcam but no valid trace is detected in the Vcam, the speed and direction of the of the ball will be measured just from the Hcam.
Vertical launch angle will be taken from the loft of the selected club.
Low trace brightness
The Vcam ball trace brightness can be substantially increased by using high intensity narrow beam IR lamps next to the Vcam that are pointed at the trace capture area.
The above 200 LED IR lamp is just $69 on Amazon. The ball trace on the left of the above image was captured without a floor mounted IR lamp. The same ball trace is on the right but with the narrow beam high intensity IR lamp.
As you can see, there's an amazing difference in ball trace quality.

Dual lane hitting surfaces for Left / Right handed players not playing down the center line.
Customers Jim and Chris - who called within and hour of each other last week - request that the software be able to allow playing the ball off the center line of the enclosure
when the enclosure width is too small and to allow both left and right handed players to play the ball from the center line of the enclosure.
If your enclosure width is too small for you to always play the ball down the center line of the enclosure
then you can select the new "Dual Lane" mode of play if the simulator is to be used by both left and right handed players.
Click "Left handed player" ON in the Hcam window to set the Left handed player's ball launch position.
Switch "Left handed player" OFF in the Hcam window to set the Right handed player's ball launch position.
When playing, the left and right handed player will be automatically set by the game software as the player comes up.
Note that dual lane hitting mats require that two line scan cameras be used and if club tracking is required for both left and right handed players
then dual club tracking systems will be required.
December 1 2017
Its been noticed that some customers forget to press the "Save Assigns" button before switching on "Fixed Assigns" in the Vcam window.
In fact, even I forgot this once. So now the camera function assignments are automatically saved when fixed assigns is switched.
What are Fixed Assigns?
Fixed camera assignments
Up until this version of the CP, camera assignments where automatically stored every time the CP was closed out in the sequence that the cameras were detected on the USB bus.
The problem with this is that if not all cameras connected to the PC were detected on the PC at CP start up or they are appear in different sequence on the USB bus, then a new - incorrect - assignment set will be saved
requiring the user to re-assign cameras when all cameras are detected on a later PC boot.
The new assignment method - which has taken over 20 hours to code - assigns cameras via their serial numbers to the functions ( i.e. Vcam, Hcam, CTS cams 1 and 2 and Ball spin cams 1 and 2)
e.g. if a camera with serial number 4820826 is assigned to be the Hcam, then this camera will always be the Hcam and will appear as the second camera in the CP's camera window.
Once stored, (via a manual button click) these assignments will never change unless the user wishes to change them.
The issue more concerns customers that have many cameras (i.e. a CX 6 camera system) but can also occur with just a 2 camera setup.
A new "Save Assignments" button in the CP's Vcam window is used to store the current cameras to their assigned functions. Click this button after all the camera assignments have been made.
November 21 2017
Spin axis and side spin now displayed and can be adjusted in the Hcam window
August 19 2017
For PX5 users
Fix: Putting not functioning when the new "Allow putting without swing being detected" was ON
More popup help
More popup help added. F2 key toggles Popup Help on/off. Popup help automatically times out after 4 seconds. Move the mouse cursor to re-activate the help box.
Putting speed calibration
Putting speed calibration instructions are now on the Putting and Chipping page
Hcam ball speed
Usually ball speed is measured by the length of the ball trace in the floor mounted Vcam camera that views the ball from the side.
However, it is also possible to measure ball speed via the ceiling mounted Hcam that views the ball from above.
The advantage being that very high lofted wedge shots will be in the FOV of the camera whereas these shots may
may be too high to be in the FOV of the Vcam camera if the Vcam is mounted closer to the center line of the enclosure.
Note that this is a new feature that requires a complete new calibration table set and won't be ready until Fall 2017.
July 25 2017
New "Software Swing Detector" prevents inadvertent ball launches in game when retrieving balls
If you have a CTS club track camera with trigger mat or a PX2 club track sensor mat (as with the PX5) then you can optionally setup the system so that it will only launch a ball if a swing (or any movement) over the mat is detected.
You should see a new "Swing detected" message at the bottom right hand side of the CP's main window after a swing. This message appears for about 2 seconds.
Shots will only be detected by the V and H cams during this 2 second window so you can walk freely around the enclosure without any inadvertent ball launches.
Note that this option requires that all shots are made from the mat - including putting unless the "Allow putting without swing being detected on mat" is set on
Switch the "No ball launch without swing being detected on mat" in the CP's Setup window.
May 21 2017
Spin factors for back spin , side spin and spin axis can now be adjusted directly in the "Show Club Angles" window
February 23 2017
Manual club selection in CP Vcam window
You can now manually select clubs and adjust club specific spin rate factors in the Vcam window. The adjusted spin is immediately shown.
The Global spin rate adjust factor is now split in two : One for woods and the other for irons. Hold the shift key down to switch.
The adjusted spin is now also immediately shown.
Manual club selection in CP Main Window
You can now manually select club types in the CP main window.
The CP will automatically switch to "Manual Club Select Mode" when selecting a club and won't get updated from any game software club selection when in this mode.
Press any key to switch this mode off.
Smash factors can now be manually adjusted for PX1, PX2 or PX5 users that select the "Ball speed calculated from club speed" option.
The selected smash factor can either be a constant factor for all clubs or can be club type adjusted
Fix: Left/Right LA adjustment values not being stored
Typical screen shots are as in the below images
The side mounted Vcam detects vertical launch angle and speed of the ball
The ceiling mounted Hcam camera detects ball path for normal shots
and ball path plus speed when putting
