CTS Club Tracking System
Full color real time camera club tracking
! Note that CTS camera club tracking systems will - in most cases - require tracking dots or white strips to be applied to the clubs !
Photographically captures Club head path, speed & club face angle at impact to ball for unparalleled accuracy.
The CTS club tracking camera can be used as a stand-alone system to play a complete round of golf or as an add-on to the CX ball tracking cameras.
The camera is overhead mounted and is triggered either with a sensor in the mat or with an overhead mounted line scan camera.
The CTS TD can be used to play a complete round of golf in a simulator
In contrast to those low cost pads on the market that make all sorts of wonderful claims about their accuracy
with a mere 16 or 32 optical sensors but with no evidence to back their claims up and provide no method for the user to verify the accuracy,
the GSA Golf CTS shows photographic evidence of every shot using a 1.2 million pixel camera.

Camera Club tracking with or without tracking dots
Single or Dual cameras
The CTS Pro Color features dual cameras that capture freeze frames of the club before and at impact to the ball.
Precise digital and programmable timing between the frames ensure that club speed, face angle and club path acquire an accuracy never before seen. And - due to our open technology - it's all verifiable by the user.
More accurate then any optical sensor pads and mats, the CTS Pro Color club tracking captures fades, draws, hooks and slices like no other system on the market.
In fact, the CTS Pro is destined to be the de facto industry standard by which all other club tracking systems will be measured.
The CTS Pro can be used to play a complete round of simulated golf even as a stand alone system. All shots from 200 mph drives to 2 inch tap in putts are detected.
Two HD images are captured with the dual USB HD color cameras in the CTS Color Pro. Note that tracking dots need to be applied to the club with the CTS Color Pro.
Image processing consists of removing pixels that are associated with the underlying mat which will leave just the club head, shaft and ball.
Further processing will detect the club face angle at impact to the ball, club speed and path.
The above images show the CP software detecting the club face angle of a wood or driver and an iron. Over 1000 scans of the club face are made using the high definition color images of the club at and before impact to the ball.
Note that the pink cross hairs show only a tenth of the actual number of club face perimeter points that are detected so it is very accurate. i.e. If all the over 1000! plus points would be shown then it would be a continuous line of cross hairs.
Notice that the software is also detecting other parts of the club other than the club face itself. i.e some parts of the club shaft are detected as not being the underlying grass mat surface as are stray parts of the club top and grass mat.
These, however, are eliminated by grouping the points and determining which group is the largest which would normally be the club face. Once the largest group of points has been detected then we just take the two ends to calculate the club face angle.
This is done for the second frame as well and using the two frames we can determine the club path.
As the two frames are precisely timed to be 2 milliseconds apart, we can thus determine the exact speed of the club by measuring the distance the club has traveled during this time window within the two frames.
The CTS Pro's hardware includes dual HD color cameras with powerful zoom lenses, trigger and timing electronics, dual LED flashes and a 24" * 12" fairway grass trigger mat.
Note that the CTS Pro Color can be used as a stand alone system to play a complete round of simulated golf as well as an add on the the CX2 ball tracking system.
As the CTS captures freeze frame HD color images of the club just before impact to the ball and the ball is clearly visible, it can calculate the ball on club face deviation from the sweet spot.
White strips on drivers and woods
Note that CTS camera club tracking systems will require tracking dots or white stripes to be applied to the clubs
Note that with most woods and drivers that feature a bulged face, a white stripe will be required to be adhered to the club's top leading edge in order to achieve face angle accuracy
The above images show what can happen when using a bulged face wood or driver club with and without a white stripe
The software couldn't detect the exact face angle of the wood without the stripe (image left) but could easily with the white stripe (image right)
All CTS systems come complete with a set of pre-cut white self-adhesive strips for your woods and drivers
If your driver and / or woods already have a white stripe on them then you won't need to use the strips.
Old worn irons. White strips on Irons
Most times it will necessary to apply a white strip or tracking dots to the lower leading edge of irons too
The above images are of an old 2 iron that - although the face angle was detected without a white strip ( image left) , this cannot always be guaranteed.
The image on the right is with the white strip.
Composite frames 1 and 2 of grooved iron
CTS trigger mat
24" *12" fairway grass true feel trigger mat.
The CTS trigger mat sends a trigger signal to the club tracking camera(s) just before the club strikes the ball.
It's important that the club images are captured before actual impact to the ball as club face angles will change after impact

How the CTS Color Lite detects club path
As it is a known and scientifically proven fact - obtained by using high tech measuring instruments- that ball direction is 85% of club face angle,
the CTS Lite can calculate with some degree of accuracy the club path given the ball direction (obtained by the Hcan ball path camera) and the exact club face angle at impact to the ball.
For all practical purposes then, actually measuring club path - as the CTS Pro does - is not really required for the average player.
It should also be pointed out that club path is a rather subjective quantity as the player will be swinging the club in an arc and thus the club path is constantly changing.
So the questions begs, at what points should the club path actually be measured. i.e. between the last 3 inches of the club path before impact to the ball or maybe the last 4 or 6 inches?
As the swing path is an arc, changing the measuring points will always result in different club path angles with the exact same swing.
Note that the CTS color camera can also be switched to tracking dot mode if required
An additional CTS camera can be used to measure club Angle of Attack
CTS tracking dot modes
There are two types of tracking dot modes available with the CTS
1: Extended exposure time mode
2. Freeze frame mode
Extended exposure time method
The above image shows a wood using tracking dots with and extended exposure time
The dots leave two traces of the club traveling at high speed. These traces are then used to measure club speed, club face angel and path.
The main advantage of this method is that only one camera is required to capture all this data and there is no visible flash
Freeze frame method
The CTS freeze frame method uses a very fast (around 80 micro second) exposure time to grab freeze frames of the dots.
When using two cameras (as in the CTS Pro and CX4 system) the result is simply the most accurate and precise club tracking system on the market today.
CTS tracking dots
CTS running in tracking dot mode requires one or two reflective tracking dots be adhered to the top of each club.
The CTS software has now been modified to detect accurate club data with clubs like the M1 driver from Taylor Made that feature a dark club face and a white top.
The new CTS software mod scans the club image to determine the color of it's top and accordingly changes the face detection to this color. Face angle detection is then the transition points to this color instead of the face itself.

The new method also works with pink clubs.
The above images show club face detection under normal ideal conditions
Reverse IBS color camera club detection
Using a new method - which we call "Reverse Image Back Ground Subtraction" - GSA Golf color camera club tracking has been immensely improved
No matter what color the club is (other than green of course) it will always be detected provided there is a good contrast betwen the club and the underlying surface
Even old scruffy vintage wooden clubs are detected provided there is a good contrast betwen the club and the underlying surface
Most irons are easily detected provided there is a good contrast betwen the club and the underlying surface
Note that CTS camera club tracking systems will most probably require tracking dots or white stripes to be applied to the clubs
and that the above images of club face detection without tracking dots or white stripes cannot be guaranteed
Use the CTS Color Pro with the CX2 ball tracking system for the perfect combination of both worlds of ball and club tracking.
This system is called CX4
From $ 5,198.00
The CX3 C system is the same as the regular CX3 system but uses a single color club tracking camera to detect fades, draws, hooks and slices without the requirement to apply tracking dots to the club.
Data captured with the single HD club tracking color camera: Club face angle.
Club path and speed calculated from ball data
Vcam and Hcam cameras measure ball launch angle, speed and path.
The CX3 system will also be available in our new Surround casing later this year

Pros and Cons of CTS Color vs CTS tracking dot
Advantages of Tracking Dot CTS
1. All club data - club face angle, club path and speed - are captured with one single camera for all clubs
2. The camera is IR so there is no visible flash
Disadvantages of Tracking Dot CTS
1. One or two small tracking dots need to be applied to the top face of the club
2. While it is easy to apply two tracking dots to the top face of woods and drivers so that club face angle can be detected,
it's not possible to use 2 dots on irons as the top face is angled back and thus club face angle will always appear open with irons.
Club face angle is then calculated from a ratio of club path and ball path with irons
Advantages of Color camera CTS
1. With bright or white clubs, no tracking dots need to be applied to the club
2. Club face angle is detected with both woods/drivers and irons
Disadvantages of Color camera CTS
1. in order to capture both club path and speed in addition to club face angle, two cameras are required (CTS Pro).
If using just a single camera ( CTS Lite ) then only club face angle is detected.
Both systems detect fades, draws, hooks and slices though
2. There is a visible flash with every shot
The flash is verry fast (1/10000 of a second) and concentrated onto the small hitting mat area though
Note that with most woods and drivers that feature a bulged face,
a white stripe will be required to be adhered to the club's top leading edge in order to achieve face angle accuracy
Note: All single camera CTS systems can be switched to tracking dot mode if preferred
SX line scan camera issues when using the CTS Color
Depending on lighting conditions and the distance the CTS unit is away from the line scan camera,
the CTS flash may be picked up by the line scan camera which will interfere with the V and H cam ball tracking.
The minimum recommended CTS to SX line scan camera distance is 6ft.
If experiencing SX flash pick-up issues then the SX will have to be replaced with a trigger array that is not affected by CTS flashes.
Customer objections to using tracking dots on their clubs
A major critique we hear from many potential CTS customers is " I don't want to have to stick any kind of tracking dots or strips to my clubs"
Well - unfortunately - there's no way to avoid this - as all other camera based golf simulator manufacturers have discovered.
Even the most expensive camera based club tracking systems in the world - costing upwards of $18,000 - haven't figured this one out yet.
Our R&D has come a long way to better the situation but - alas- it still isn't perfect so we're still recommending using either tracking dots or our supplied white plastic strips to be adhered to all clubs.
Note that the tracking dots or strips we supply are easy to apply and remove and won't in anyway harm or damage the clubs.
Oh - and by the way - if you're looking at a golf simulator manufacturer's product that claims that their camera based club tracking system tracks precise club data without tracking dots or markings,
then don't fall for this marketing hype unless you see absolute concrete evidence to the contrary. Because otherwise it simply doesn't exist!
Note that the below mentioned products are in the $15,000 to $18,000 range whereas our systems using camera club tracking cameras are omly in the $4,000 range
Club Tracking dots are also used by the world's No. 1 golf Launch monitor systems from Foresight Sports
Another example of a hi-end club tracking system is from GearsGolf
Note that they also require tracking dots to be applied to the club

Are you looking for perfect accuracy to work on - and improve your game ?
Or do you just want to play a few rounds with your buddies for entertainment ?
If the latter then just a regular optical sensor club tracking mat will suffice - or even no club tracking at all
but if you're really serious about club tracking accuracy in order to improve your game then you won't mind sticking a couple of plastic tracking dots on your clubs
