CTS Ccam Monochrome tracking dot Setup instructions
The camera should be overhead mounted directly over the ball/tee position on the supplied hitting mat. Image on right shows the new X,Y adjustable mount.
The camera is pre-focused but may require slight adjustment if not mounted at the standard height of 9 to 10 ft.
Important ! --- Camera function assignments (CX systems)
In the control panel cam 1 is the ball launch angle camera, cam 2 is the ball path camera, cams 3 & 4 the club tracking cameras and cams 5 & 6 the ball spin cams.
Check that all cameras connected to the PC and go the "Cameras" window of the Control Panel
The control panel is designed to see the cameras in the following sequence
Camera 1 is the Vcam (The floor mounted Vertical ball launch camera in a CX2 to CX6 system)
Camera 2 is the Hcam (The ceiling mounted horizontal ball path camera in a CX2 to CX6 system)
Camera 3 is the Ccam (The ceiling mounted club tracking camera - frame 1 in a CX3 to CX6 system)
Camera 4 is the Ccam (The ceiling mounted club tracking camera - frame 2 in a CX4 to CX6 system)
Camera 5 (bank 2) is the Bcam ball spin camera - frame 1 (floor mounted in a CX6 system)
Camera 6 (bank 2) is the Bcam ball spin camera - frame 2 (floor mounted in a CX6 system)
To identify which camera is which you can click the "Soft Trigger" button to grab a new image or set the camera to "Video Stream Mode".
From the images you should be able to see what camera was being triggered.
If you find that cameras are not being assigned in the correct order then you can manually re-assign the cameras.
To do this, 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.
Note that color cameras - as used in the CTS club tracking systems - will appear in monochrome if not correctly assigned.
i.e. if a color CTS camera appears as camera 1 in the control panel then the images will show in monochrome instead of color.
CTS color cameras must always be assigned to camera positions 3 or 4.
The CTS camera is triggered by a sensor in the supplied trigger mat.
The mat should be placed so that the overhead halogen lamp is directly over the sensor.
CTS Club Tracking camera video
This video shows the setup parameters for the club tracking camera with examples of various club shots. If using the Ccam CTS as stand-alone system - i.e. without ball tracking cameras - the section showing how to adjust the club/ball smash factor will be of interest.
CTS tracking dots
The system requires one or two reflective tracking dots be adhered to the top of each club.
60 club tracking dots and 18 squares are supplied with the system.
For irons you can use the square ones so that they fold over the club edge easier.
Cut the squares ones in half to get two long sided track reflectors.
The above image is an actual camera shot using a HD lens of a 3 wood just before and after striking the ball at nearly 100 mph.
You'll notice that the club itself is barely visible but the trace of the reflective tracking dots is very visible.
SD lens cameras capture a smaller image but still functions well. An advanatge with SD lens systems is that they are easier to aim and focus.
Applying the 2 tracking dots is quite simple on woods, drivers and putters.
Just ensure that the 2 dots are in line as accurately as possible and are set reasonably far apart.
Also ensure that the surface of the club is clean and grease free before hand.
Use of a alcohol based cleaner such as a lens cleaner fluid is recommended
Ball launch position XY
It's important that the system knows where the ball on the tee or normal hitting position will be. To do this:
Place a ball on the tee and click the "Soft Trigger" button to grab an image.
Select the "Ball launch position XY" and use the keyboard arrow keys to mark the position.
Club face angle adjustments - Double tracking dot club tracking
The top edge of irons and wedges may be slimmer than the diameter of the reflective dots in some cases but this is not a problem.
Just wrap around any overhanging edges to the back or face of the club.
For high lofted wedges we recommend that the dots be adhered to the lower side of the actual face of the club.
This ensures that they are more visible to the camera.
You'll notice that is is not possible to get the dots in line with most irons.
In this case the Face Angle Adjust setting in the camera software window (see below) is used to compensate so that the correct face angle is measured.
To set the Face Angle setting to compensate for the off line dots on an iron,
place the club as square as possible on the mat and move the club over the trigger sensor to capture a camera shot.
The software will then measure the club face angle. This angle will be some degrees open.
Note: Switch off the Parallel trace line checking when setting club angles otherwise camera processing won't function correctly at these very low club speeds.
Also run the control panel without any golf game software running. i.e. ProX, GSA Golf or E6
Click the Face Angle Adjust radio button and use the left and right arrow keys on your keyboard to select the club (i.e. 3 iron, 4 iron, 5 iron etc)
as shown on the right-hand side of the Face Angle Adjust parameter setting in the camera window.
Now press the F5 key to set the adjustment so that the measured face angle is zero.
You can also increase or decrease this setting manually with the up down arrow keys on your keyboard.
The measured Face angle is shown on the 3rd line down on the right hand side of the screen.
The setting is automatically saved so no need to click a special save button.
Repeat this procedure for all the irons that you are using.
The setting can also be used for any other clubs in use if required.
The club tracking software shows 3 stages of the club path and club face angle.
The light blue cross hairs at the start of the trace (right hand side of the image) show the club face angle just before impact.
The blue cross hairs club face angle at impact and the yellow cross hairs just after impact to the ball.
The user can choose which of the face angles are sent to the game software
but using the face angle after impact is not recommended as the face angle will change due to the impact force.
When a valid shot is detected by the Ccam camera, the "Launch Data Ready ..." message will appear in the Control Panel's main window.
Ensure that the Ccam button is selected in Camera 1 box if the Ccam is the only camera being used in the system.
If you have ball tracking cameras then the club tracking Ccam /Bcam camera is assigned to camera 3
The above image shows the standard club track camera lens dials
The above image shows the standard camera settings for the Ccam for normal shots.
The above image shows the standard settings for the Ccam when putting.
Note: When using only the Ccam without ball tracking cameras,
putt with your head slightly behind the ball to ensure that the camera has a clear view of the club as it makes contact with the ball.
Single tracking dot Ccam camera club tracking
Single tracking dot camera club tracking is now available with the new CP.
Using two tracking dots - especially on irons - required a rather lengthly setup so we are simplifying this with an optional single tracking dot method.
This option will allow users to place just one tracking dot on the clubs instead of two and thus the requirement to setup iron face angle adjustments will no longer be necessary.
In this case, club face angle is calculated from the ball path relative to club path.
Face angle is almost always 85 percent of ball path so we can use this ratio to show club face angle.
Woods and drivers don't normally require face angle adjustment though so the user can opt to use double tracking dots for just these clubs and leave the irons on single dot tracking.
The system will automatically detect if a one or two tracking dots are on the club and - if two - whether or not a specific club setup has been made for the player.
If no player club set adjustment profile exists, then a default adjustment profile will be used.
Single / Double trace dot tracking is automatically detected so there's no extra setup required
For single trace club tracking, place the single tracking dot over the sweet spot of the club. i.e. usually in the center.
Setting the ball launch position
The ball will always be played from the exact same spot on the hitting mat when using the club tracking camera.
Note: If you have ball tracking cameras then the ball can be played from other surfaces. Club tracking won't be available in this case.
In order to calculate the face angle at impact, the ball launch position should be setup in the system.
To do this, place a ball on the tee holder on the hitting mat and click the Soft Trigger button in the Club Tracking window to grab an image.
Select the Ball Launch Position button and use the keyboard's arrow keys to move the hair-line cross to the center of the ball.
Select the Ball Size button to adjust the green borders to the ball size.
Ball on club face position scaling factor.
The After Shot swing analysis window now features a "Ball on club face" position scaling factor.
To adjust, hold the shift key down (a factor is then displayed) and use the arrow keys on your PC's keyboard to move the ball.
Use the up/down arrow keys for the top view club/ball image, left/right arrow keys for the club/ball image front view.
Test by playing shots striking the ball on the heel or toe of the club and comparing to the ball position images in the swing analysis window. Adjust accordingly if required.
Club loft adjustment
Club lofts can be changed with the CP.
If you are using a GSA Golf system that doesn't measure ball launch angle (like the Ccam or PX2 stand alone systems) then the loft of the club will be used for the launch angle. The ability to change the CP's default club loft angles allows you to match them with your real clubs and/or adjust a launch angle to your normal angle of attack for a particular club type. i.e. if hitting on the down swing then decrease the the loft angle, if hitting on the upswing then increase the launch angle.
If using a system that does measure launch angle then this feature will allow you to fine tune the club attack angle calculations.
Adjustments are made direct in the CP's main window by selecting the club with the T or shift/T keys and then the loft angle with the K or shift/K keys.
The standard loft for each club is displayed next to the current loft angle.
Adjusting measured club speed & setting the pixel scale
Club speed is dependent on the scaling factor, average length of the two trace lines, lens zoom and camera shutter speed.
To setup the club track camera so that the correct club speed is measured, the pixel-to-distance scale must be set correctly.
This scale is used to calculate the distance (the length of the trace in pixels) the club traveled during the camera's exposure time.
This is then used in the equation : Speed = Distance/Time
To set the scale correctly do the following:
1. Place a golf ball on the hitting mat and click the the Soft Trigger to grab a frame.
2. Click the Set Scale button
The image processing software should find the ball and it's size and automatically set the scale for you.
Note: The image processing that finds the ball is from the LX software in the control panel so if for some reason the ball is not found or its size is not correct then go to the setup window and switch to LX Lite.
Then go back to the camera window and click the Soft Trigger button to grab a new frame of the ball. Adjust the settings ( min ball gray scale and or / ball max or min size) until the ball has been detected correctly.
Then switch back to Ccam mode and repeat the Set Scale procedure.
As the diameter of a golf ball is a known constant i.e. 42.67 mm, we can use the number of pixels in the camera image for this diameter to calculate the scale.
In the above image the ball's diameter was 204 pixels for 42.67 mm. The scale is then 42.67 / 204 = 0.2090 so that 1 pixel = 0.2090 mm
Alternatively, you can measure the size of the ball in the image by right clicking on the left side of the ball and moving the mouse cursor to the right side. The distance will be shown in pixels.
In the above image, the distance was 208 pixels. Scaling factor was set o 0.2050 which resulted in a ball size of 42.64 mm.
Note: When using the Ccam as a stand alone system (i.e. without ball tracking) ball speed (and thus carry) will be totally dependent on the club speed.
In this instance adjusting club speed via the Scale ratio will effect ball carry distance.
This method of adjusting ball carry distance is however is not recommended.
To adjust carry distance when using only a club track camera use the slider bars in the setup window.
Another issue when using the club tracking camera as a stand-alone system - ie without ball tracking cameras - is that
a waggle or addressing the ball so that club head moves over the trigger sensor can be sensed as a valid swing and an inadvertent ball launch will occur.
This can be easily avoided by simply placing the ball just behind the trigger sensor so that ball triggers the camera instead of the club head.
The resulting club data will be then just after impact.
Valid swing checks
The club track image processing goes through a number of checking routines to verify that the captured image is of a valid swing
and not of anything else that might have triggered the camera.
Two of these checking routines are user adjustable:
Max face point spacing and Parallel trace line checking.
Max face point spacing is simply a check of the distance the two traces are apart.
As this distance will vary slightly from club to club and is dependent on the zoom of the lens, the value is user adjustable.
The trace line distance is displayed at the top of the screen after every shot (see yellow arrow)
and the max value should be set to a number so that no club produces a trace line spacing greater than this.
In the above image the spacing was 206 pixels and the max setting set to 300.
Parallel trace line checking
This check simply checks to see that the two trace lines are parallel.
Images captured by other objects triggering the camera (like your hand as you tee up) are not likely to produce two trace lines in parallel.
This check routine should be switched off when setting up the club and adjusting club face angles
as the very slow movement of the club may not always produce two lines of sufficient length for the routine to function correctly.
More about club speed
If you look carefully at the above image - of a right handed player's 3 wood shot - you'll notice that the two trace lines are not quite the same length.
The upper trace line is slightly longer than the lower trace line.
This is due to the swing arc which dictates that points further away from the the center of rotation are moving faster than those nearer the center of rotation.
Your hands for example are moving far slower than the club head in a full shot.
As the tracking dot on the toe of the club is further away from the center of rotation than the dot on the heel of the club, it will be moving faster.
To compensate for this the system takes the average of the two speeds measured from the two tracking dots.
This will then be the speed of the center of the club head.
(by the way, neither optical sensor nor radar club speed detection systems take this into account)
