Camera Installation Q & A

Q: The cameras are connected to the PC but I don't see any images

A: Check the following

1. Are the camera drivers installed?

Go to the "Auto method of installing the camera drivers" on the camera installation page here

2. Are the cameras detected in the "Cameras" window of the Control Panel (CP) ?

You should see the message "Camera found" above each camera button in the Cameras window of the CP

3. When you select the "Video Stream Mode" do you then see new images ?

If yes then the cameras are running okay so the fault is with the camera trigger from the SX line scan camera

4. Are the cameras really connected to the PC via the USB cables?

Each camera must be individually connected to the PC via it's own USB cable

5. Are the USB cables too the cameras too long?

USB cable specs state that the maximum length of a USB cable between hubs is 3 meters or 10 feet

To fix: use powered USB hubs for every 10ft of USB cable

To test if it's the cable lengths causing the problem, connect each camera to the PC using just the supplied 6ft USB mini B cable.

If you then see that all cameras are running and images are being grabbed when set to "Video Stream Mode" in the CP cameras window,

try connecting one of the supplied 9ft USB extension cables to the camera using a powered USB in between the 9ft cable and the 6ft cable.

If the cameras are still running okay and you require more USB cable length, add a second 9ft extension cable to the 6ft cable so that there is a 15ft (9 + 6) length of USB cable going from the powered USB hub to the camera

and a 9ft extension going from the USB hub to the PC.

Note that then the 15ft length exceeds the maximum safe length of a USB cable without hubs so if the camera is then no longer functioning correctly

then a second powered USB hub will have to be added to the cable 6ft - to - 9ft USB connection.

6. Are the cameras connected to a separate internal hub and bus on the PC ?

Often times USB ports on the PC will share the same internal hub and bus on the PC's mother board

Go to "How to determine what USB ports are sharing a USB bus or hub on your PC" on the Camera installation page to read more

Connecting multiple cameras to ports that share one USB Host Controller will split the USB 2 480MBit/s speed.

e.g. 4 cameras on one controller will then only run at 480/4 = 120MBits/s and probably won't function

Connecting multiple cameras to the same USB Hub on the PC's mother board will split the max hub's output of 2.5 watt power

Power - in this case - will be shared to the cameras connected to it and this will cause the cameras to not function as each camera requires 2.0 watts to function.

USB over Cat cable extender - up to 150ft

An alternative to running USB cables over long distances with powered USB hubs every 9ft, is to use Cat5 cables with a USB over Cat unit at either end.

We are currently testing this method.

 

Q: I see new images when in "Video stream mode" but not when the cameras are triggered by the SX line scan camera

A: Check the following

1. Are the two RCA cables connected from the SX camera to the Vcam and Hcam cameras ?

2. When you turn the SX sensitivity dial on the remote control left (anti clockwise), does the green LED light on the SX cam turn on?

3. Is the ceiling mounted IR LED lamp on?

The LEDs in the lamp will glow a dark red when on. Note that there's a photocell on the LED lamps that automatically switch the lamp off when ambient light is in the room.

To prevent this, stick a small piece of black electrical tape over the photocell

Q: My cameras only trigger with high lofted shots

A: This will occur when the SX camera's sensitivity is not set high enough.

To set the sensitivity, turn the dial left until the green light comes on and then turn very slowly back until the green light just goes off again.

Note: do not stand under the SX cam when doing this otherwise your body will cause IR light reflections to get back into the camera. Stand as far away from the SX camera as possible

Q: I've set the SX sensitivity as high as possible but it will still only detect high lofted shots

A: This will occur when the SX camera's sensitivity cannot be set high enough due to the underlying surface reflecting too much light

Are you using the supplied black carpet under the SX camera?

We have lower reflective padded turf carpet now should you prefer not to use the black carpet

Q: My cameras are all running but seem to be in the wrong order.

i.e. camera 1 is the Hcam and camera 2 is the Vcam

A: This due to incorrect camera assignment

The correct assignments are Camera 1 = Vcam, Cam 2 = Hcam, Cam 3 = CTS frame 1 and Cam 4 = CTS frame 2

To change the camera assignments

select the camera in the CP cameras window, hold both the shift and ctrl keys down, and press the left or right arrow keys to move the camera up or down the sequence.

Press the "Soft Trigger" button to grab a new image and confirm that it is the correct camera assignment

If you're using the latest CP version V 8.6.4.9 or greater, switch the camera fixed "Assignments" OFF to start with and restart the CP.

Once the correct camera assignments are made you can save them by clicking on the "Save Assigns" button in the Vcam window.

Q: When I re-start the PC, the camera's order changes

i.e. camera 1 is the Hcam and camera 2 is the Vcam etc

Use CP version V 8.6.4.9 or greater, switch the camera fixed "Assignments" OFF to start with.

Once the correct camera assignments are made you can save them by clicking on the "Save Assigns" button in the Vcam window.

Q: Why are my Vcam and/or Hcam images upside down or back-to-front ?

A: This usually due to incorrect mounting orientation but you can easily flip the images

If the image appears up side down, click the "Y reverse" option on the right hand side of the window

If the image appears back-to-front, click the "X reverse" option

Q: When I hit a shot nothing happens and no ball is launched in the software

A: Check the following

1. Is the SX Line scan camera triggering the V and H cameras?

When you strike a ball you should see that the bright green LED lights up for a second or two.

If not then click the above image go to the Line Scan camera setup page.

2. Check the Vcam and Hcam images to see if the ball trace has both the green cross hairs on it at both ends

Your V and H cam images should look similar to the above images with the two green cross hairs at both ends of the ball trace

Ensure that no other bright objects in the valid FOV of the cameras are being picked up as in the above image

3. Check the Max path angle and max camera de-activation time in the Hcam window

If the ball path (left or right) of a shot was greater than the "Max path angle" then the shot will be declared invalid and the ball won't launch in the software

After a shot, the cameras are de-activated for a few seconds to prevent the following club or player from re-triggering the cameras.

If you play a ball during this de-activation period then the cameras won't capture the ball and the ball won't launch in the software.

The de-activation time can be user set from 2 to 8 seconds.

3. Check that you have selected the correct game software you are using in the CP's main window

In the case of TGC, ensure that the TGC server is running and you see the message "TGC connected" in the CP

Q: After playing a while a camera will stop working

A: This is usually due to the USB cable length being too long

USB cable specs state that the maximum length of a USB cable between hubs is 3 meters or 10 feet

It's possible that the cameras will function with longer cables for a while but connections may become unstable.

With the GSA Golf camera system it is usually the Hcam camera that is effected by this as the cable to this camera is the longest

To fix: use powered USB hubs for every 10ft of USB cable

Note: Do not connect more than one camera to each USB hub!

Other than SX line scan cameras, each camera will require it's own individual USB powered hub

Go to the USB camera cables section on the Camera installation page to read more

Q: I can only get 2 out 3 cameras or 3 out of 4 cameras to work

A: 1. This is usually due to the USB cable length to cameras being too long and/or cameras are connected to a single USB bus on the PC

USB cable specs state that the maximum length of a USB cable between hubs is 3 meters or 10 feet

To fix: use powered USB hubs for every 10ft of USB cable

A: 2. Each camera shoulb be connected to a separate internal hub and bus on the PC

Often times USB ports on the PC will share the same internal hub and bus on the PC's mother board

Go to "How to determine what USB ports are sharing a USB bus or hub on your PC" on the Camera installation page to read more

A: 2. Your PC's mother board is shutting down power to the internal USB bus when the overall power consumption exceeds a certain threshold

Usually adding an extra USB multi-port controller card to the PC will fix this problem

If it's just one extra camera that is not working then a lower priced single channel card will probably suffice, otherwise you'd require a multi dedicated channel USB card

Go to the USB ports section on the Camera installation page to read more

Q: How can I hit fades and draws with the CX2 system ?

A: Click the above button to read how to do this

Q: How can I hit fades and draws with the PX5 system ?

A: Your PX5 system will automatically detect fades and draws (plus slices and hooks) based on the relative club face angle to club path

Ensure that after a shot that the system actually detected club data. Check the CP's main window for valid club data.

If not, then check that the "Valid swing loop count" in the "Sensor Settings" is set to 12.

The "Sensor Settings" window is accessed via the "Setup" windows

Q: How can I use the SX line scan camera without using the supplied black carpet?

A: In order to do this you'd need:

1: If not using the latest SX camera - the SX op-amp upgrade with the new lens (cost for the upgrade with lens is $149 plus shipping)

2: use low reflective turf carpeting like our new turf carpetig we now supply

Example of low reflective turf:

6ft * 12ft less reflective padded turf grass mat suitable for camera systems

Price $399 + $99 shipping

You may find that the turf carpeting you are already using works well too so try this first

Q: How can I increase the range left and right of the SX line scan camera ?

A: Once again - If not using the latest SX camera - you'd require the SX op-amp upgrade and the new lens (cost for the upgrade with lens is $149 plus shipping)

In addition - as the increased 70 degree wide angle lens is only really of use if lighting is also available at these angles -

two extra IR LED lamps (cost around $70 each) mounted left and right of the SX camera would be required

Note that you can also use multiple SX cameras to increase the ball detection range but this method is a lot more expensive

Q: How can I adjust the carry distances when they are not correct?

Ball speed - and thus carry - is calculated by the length of the ball trace in the Vcam.

The speed of the ball is dependent on the distance the ball traveled within the camera time frame (shutter speed).

The camera sees only pixels so a real distance-to-pixel scale factor must be used to calculate the real distance traveled.

Thus, adjusting the Scale factor will alter the measured ball speed which in turn will adjust the distance/carry the ball will have in the golf simulation software.

Before adjusting the scaling factor, check the below described possible issues and factory calibration settings

As measured ball speed is directly proportional to the length of the ball image trace , it's important that the ball trace from beginning to end is well illuminated.

With really fast high speed shots, it is possible that the ball won't be sufficiently illuminated to leave a solid trace and appears to taper out towards the end.

The image processing software in this case won't detect the full length of the trace and thus the measured ball speed will be too slow.

In order to avoid this problem you either need to tilt the IR Lamp further towards the screen

or additional illumination (either IR LED or Halogen) has to be added further ahead towards the screen.

In addition, an IR LED lamp should be mounted next to the Vam so that the ball is also illuminated from the side.

The side mounted Vcam IR lamp should be tilted upwards around 18 degrees

Camera calibration

All current GSA Golf Control Panel versions and updates now include a factory set camera calibration table

that negates any user requirement to calibrate the cameras themselves.

The table consists of 3 calibration tables each consisting of 126 entries

for various distances the Vcam is from the center line

Vcam distances from the center line are 5ft, 6ft and 7ft.

Note that the calibration table "calibLRex.csv" is placed in the "C:\Program Files (x86)\GSAControlPanel\data" folder when you download the latest CP update.

In order to use it, the new "Factory Calibration" option must be on.

Calibration factors used now displayed

The calibration factors used for the current shot are now displayed in the Vcam window.

These are Speed adjustment, Launch Angle (LA) adjustment and the index number into the calibration table.

In the above example, the raw speed of the ball was reduced to 84% and the raw LA increased by 38%

Extended calibration "Scale" factor = 0.2780

Note that the Scale factor for the calibration tables was set to 1 pixel = 0.2780.

This scale factor used with the calibration tables should result in exact ball speed measurements across the entire 0 - 60 degree launch angle and +/- 20 degree path range.

Increasing or decreasing this scale will result in decreased or increased measured ball speed across the entire range should you care to change it.

Don't forget !

If your Vcam is mounted on the left side of the enclosure, ensure that the "Vcam Left" option is ON

otherwise your calibration will be reversed

Also don't forget to set the distance your Vcam is from the enclosure center line

Currently distances are 5ft, 6ft and 7 ft.

If your Vcam is over 7 ft away from the center line then just use 7ft setting for now.

Other distances will be available later this year

Also don't forget to set the amount of calibration to 100% for both speed and LA to start with

Later you can reduce or increase the amount of calibration for both Speed and LA to suit

In the above example the speed calibration was reduced to 50% so that any ball speed adjustments for ball hit left or right will be 50% less

Note that the calibration tables where made with a ball to trigger distance of 5ft.

And don't forget to set "Extended Calibration" ON and "Factory calibration" ON

Note that these are default ON with the new CP releases

The carry factors ON/OFF button is at the top of the Vcam window

And finally, don't forget to switch "Carry factors" OFF

Select the "Adjust speeds/carry distances" ON at the top of the Vcam window

and "Ball speed controls" to their default of 100%

Q: Why, when I adjust the carry distances for woods and long iron shots to the correct carry distances

are my short iron shots then too far ?

Q: Why, when I adjust the carry distances for short irons to the correct carry distances

are my woods and long iron shots then too short ?

Actually this shouldn't occur with the calibration set on but in case it does, you can use the "LA Speed" adjust factor in the Vcam window

The LA Speed adjust factor will adjust the measured speed depending on its launch angle

In the above image example, a maximum speed increase of 16% will be applied at a launch angle of 60 degrees

This 16% speed increase will be spread over a launch angle range from 20 degrees to 60 degrees

i.e at 20 degrees or less there will be no increase in speed

at 40 degrees (i.e. half way between 20 and 60 degrees) an 8% speed increase will be applied

Note that this speed adjustment can also be reversed so that the measured ball speed will decrease with increasing launch angles.

Use the left / right arrow keys to set the adjustment to minus (i.e. -16% or less)

The "LA Speed inc" text will then read "LA Speed dec"

"inc" stands for Increment and "dec" for decrement

Q: How can I adjust the chip and putting distances when they are not correct?

Go to the putting and chipping page to see how to do this

Q: Why do balls hit left go further than balls hit right (or vice versa)?

If your Vcam is mounted on the left side of the enclosure, ensure that the "Vcam Left" option is ON

If your Vcam is mounted on the right, ensure that the "Vcam Left" option is OFF

otherwise your calibration will be reversed

Also don't forget to set the distance your Vcam is from the enclosure center line.

i.e.5ft, 6ft or 7ft

Q: I don't see "Factory Calibration" in my Vcam window

You must be using an older version of the Control Panel.

Go to the "Tech News" page and download and install the new version of the GSA Golf Control Panel

Q: Shots are always going left or straight (or right and straight)

Check your ball launch positions in both regular shot mode and putting mode in the Hcam window

Q: How can I prevent inadvertent ball launches when I go to retrieve balls lying around in the enclosure area

V 8.6.5.6

As of CP version 8.6.5.6 you can use the software method

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.

Alternatively, use one of the below add-on products

New "Line Scan Shot Detector" prevents inadvertent ball launches in game when retrieving balls

Occasionally inadvertent ball launches may occur when walking within the line scan area - usually to pick-up balls.

The addition of this new line scan camera placed halfway between the Hcam and hitting area will prevent this.

The "Line Scan Shot Detector" is used as a trigger gate that only allows the main line scan camera's trigger signal to pass through to the ball V and H cameras if an object passes through its FOV.

It can also be used to detect if someone is standing at or close to the hitting position and thus blocks the main trigger signal if no one is at the hitting mat.

Price: $ 499.00

New "Optical Sensor Shot Detector" prevents inadvertent ball launches in game when retrieving balls

A lower cost alternative to the line scan camera shot detection, is to use an optical sensor shot detector. This sensor is emedded in the hitting mat just in front of the ball launch position.

Up to 3 sensors can be used: one in the hitting mat for regular shots, one on green surface for putting and one for the rough or sand shots.

Price: $ 199.00

Q: Why does my PX2 club tracking mat sometimes read exaggerated club face angles

A: Usually this only occurs if the ball is not being played from the tee holder position on the sensor mat.

When playing the ball from behind the tee holder, the ball will trigger the club face angle sensors instead of the club and thus erratic club face angles will be detected.

Important: always play the ball from the tee holder with the PX2 sensor mat. i.e. either with or without a tee

Other reasons are: woods and drivers have rounded faces and thus the club face angle cannot always accurately detected .

Unfortunately this is an inherent problem with all optical sensor club tracking mats, no matter from what manufacturer.

Another possible cause can be the lie angle of the club at impact being too steep and thus letting light get under the club so that the sensors are being triggered unequally.

Other than replacing the sensor mat with a camera based club tracking system, there's no absolute fix for the problem.

However, these last two causes can be greatly lessened by setting the max measured club face angle to a lower value - like 11 degrees as in the above image.

or selecting one of the "Club face easy" options in the CP's Setup window.

Q: I don't have a disc drive on my PC. Can I download all the installation files?

Yes.

Dowload the full version and run it.

GSA Control Panel (CP) full version download

Note that the full version installation will overwrite any user settings if you have had any previous GSA Golf CP installations

Download the current update and run it

Go to www.ptgrey.com

Create an account using the serial number of any GSA Golf camera you have.

Go to support downloads and enter the fields as shown below

Download the 32 bit camera SDK and run it.

Select "I will use USB cameras" and select "Install PGRUSBCam driver" when prompted.

Do not select the "USBPro" option !

If you have previously run this install program and think you may have selected the USBPro option then you must uninstall the SDK and re-run it

GSA Golf Game software download

Warning! if you already have the full version GSA Golf /RedChain software installed, downloading this free single course version will prevent the full version from running correctly
