VisTrak Stereo 3D vision cameras

VisTrak IR Stereo

VisTrak IR Stereo - The VisTrak IR Stereo system combines the stereo cameras with the VIsTrak IR in two cases.

The system features a line scan camera so that shots can be played from other surfaces like rough, sand and greens

All cameras and lights are built into the ceiling mounted cases.

The stereo cameras measure ball Speed, Launch angle and Path.

The VisTrak camera measures club face angle, club speed and path.

VisTrak IR Stereo: $ 4,999

PC requirements.

Important ! USB 3 only

The VisTrak camera in the VisTrak IR Stereo system is a USB 3 camera and must be connected to a USB 3 port on your PC.

You can identify a USB 3 port by the SS symbol next to the port

The VisTrak hi-speed camera will require a PC that is capable of running hi-speed cameras.

While most good desktop gaming PCs featuring i5 or i7 CPUs can do this, laptops are not suitable.

Current max VisTrak cable length is 32ft

VisTrak Quantum

$ 3,499

Competitively priced at just $2,999, (i.e. half the price of a Uneekor and a quarter of the price of a GC Hawk or an AboutGolf 3Trak)

the VisTrak Quantum offers all the high end features you'll ever want in all-camera tracking system.

How it works:

The VisTrak Quantum features two hi-resolution triggered stereo cameras that capture ball launch angle, spin rate and spin axis

and a hi-speed free running VisTrak camera that captures ball path, ball speed, club face angle, club path and speed.

The two stereo cameras feature zoom lenses that capture hi-resolution large images of the spinning ball within its first 12 to 24 inches of flight.

These two cameras are triggered by the VisTrak camera as soon as two frames of the ball in flight are captured.

The trigger signal to one of the two cameras is delayed by 100 micro-seconds so that the two images show spin rotation.

Triggering the two cameras with a 100 micro second delay apart from each other is the equivalent of a 10,000 fps camera, only that just 2 frames are captured.

Note that only two frames of the spinning ball is all that is required to determine spin rate and spin axis.

Stereo vision detects the launch angle of the ball.

VisTrak Quantum data capturing method

1. The VisTrak camera detects when a ball is placed in the launch zone area

2. When a ball is detected, the stereo cameras are triggered to grab frames of the ball at the launch position.

3. The VisTrak camera is then placed in full speed mode (590 fps) while constantly checking to see if the ball moves forward.

4. As soon as the ball moves, (strike frame) a trigger signal is sent (via a GPIO line) to the stereo cameras

5. The stereo cameras are programmed to delay any trigger signal by 5 milli-seconds and 5.1 ms

6. The Stereo cameras then detect the height the ball is off the ground and calculates the launch angle and the spin rate based on the ball's rotation within 0.1 ms

7. The ball path - center or right - is detected by the VisTrak camera as is the club speed, face angle and club path

8. The ball speed is then calculated from the distance the ball has traveled from the ball strike frame in the VisTrak camera and the ball's position in the stereo cameras.

Notes:

While the camera's GPIO trigger signal is very fast (just a few nano seconds), there can be up to a 1.7 ms delay (1/590 frame rate) for the VisTrak camera to detect ball movement.

At a speed of 200 mph - and in a worst case - the ball may have already traveled some 6 inches before movement had been detected.

This distance has to be taken into account when measuring how far the ball has traveled within the 5 ms time frame in order to accurately measure ball speed.

After all these operations, a final check is made to see if the data is valid and that the ball's movement extended outside the launch zone.

i.e. it wasn't just a re-positioning of the ball on the hitting mat or from an inadvertant ball contact from a club waggle (or the ball just fell off the tee).

Spin Axis

Spin axis is calculated by measuring the dot line up angle and subtracting the ball path from it.

i.e. the spin rotation angle should match the ball path angle when spin axis is zero.

Any deviation means the ball's spin axis is either left or right and the shot trajectory will curve.

The VisTrak Quantum should be available later this year

VisTrak Eagle to Quantum upgrade

If you already have a VisTrak Eagle - or are thinking about purchasing a VisTrak Eagle - and would like the option to upgrade to the Quantum at a later date,

you can simply purchase the Quantum stereo camera IR panel without the VisTrak Eagle and attach your existing Eagle to it.

Price is $1,999

VisTrak Stereo to Quantum conversion

If you already have a VisTrak Stereo system, then the conversion to the Quantum just requires exchanging the stereo lenses at a cost of $50 for the two.

Pros and Cons of the VisTrak IR Stereo compared to the Quantum

IR Stereo Pros

1. Ability to play the ball from other hitting surfaces like greens, rough and sand as well as the regular fairway mat

IR Stereo Cons

1. Unit is supplied 2 cases

2. Ball spin is only estimated

Quantum Pros

1. All components cased in one case

2. Ball spin is measured and not estimated

3. Lower price

Quantum Cons

1. Special marked spin dot balls are required to measure ball spin

2. Ball must always be played from one spot: i.e. no ability to play the ball from other hitting surfaces like greens, rough and sand.


VisTrak Stereo

individual cameras

VisTrak Stereo - Has the exact same function as the VisTrak IR Stereo but all cameras and lights are in separate casings

As with the VisTrak IR stereo, the system includes a line scan camera that allows the user to putt away from the regular hitting

The system is mounted 5 to 6 ft ahead of the player's hitting position.

VisTrak Stereo: $ 2,999
