CP 64 update 10.2.8.5

New System Pause feature

There's been a number of requests to add a system pause feature

in order to prevent inadvertent shots when teeing up or waggling the club over that ball.

Press the space bar to pause the system. Press again to restart the system.

You can also opt to have the system automatically pause after every shot in the Setup panel

You can also use a USB foot switch that is assigned to the keyboard's Space bar to pause / un-pause the system with your foots

February 15 3:15 pm

New web page dedicated to hi-speed camera shot capture in progress:

Club and ball post shot hi-speed video playback for

GC3, SkyTrak, MLM2Pro, TrackMan and Mevo etc

If you already have a launch monitor but it doesn't show post shot videos of your club making contact with the ball,

then our hi-speed video capturing systems will add this feature to your existing system.

Click above image to read more about our shot video capture systems

Page will include video export and video editing intsructions

CP 64 update 10.2.7.9

Fix:Ball back spin not being calculated correctly with LX1 systems

Coming later:

Ball Side Spin Detection from the LX1, LX2 or EVI side cameras

Usually side spin is measured from the overhead camera but in the case of the LX1, there is no overhead camera

so a method of detecting side spin from a side mounted camera has had to be devised.

Users will also be able to select which camera (Top or Side) will be used to measure ball spin.

In order to detect side spin with a side mounted camera,

we need to determine if the ball's logo or marking is rotating around the center of the ball in both ball spin frames.

If the distance each point of the logo or marking is from the center is the same in both frames, then spin axis is not tilted and thus there is no side spin.

Any deviation will show that the ball's spin axis is tilted and thus there will be side spin present.

CP 64 update 10.2.7.8

Fix: If - for some reason - the shot wasn't correctly detected, data from the previous shot may be sent to the game software.

A check for this has now been implemented

CP 64 update 10.2.7.7

New 1: Update for LX1 users

New 2: Improved club detection with short chips and putts

As part of my new "no matter what, keep the price as low as possible" strategy, I've re-introduced the LX1 Lite

Vistrak vs Rapsody

To my amazement, I’ve just learned that Rapsody MLM2 Pro - that all are raving about - can’t even detect putts or small chip and run shots.

This - in my opinion - makes this system essentially useless if it is to be used as a golf sim tracking racking system.

In contrast, my LXC detects all shots including putts and chips with 32 frame video playbacks for the same price

New lower cost VisTrak Eagle systems

Note : System can be used with floor mounted launch monitors that don't feature overhead club tracking cameras

(eg SkyTrack, MLMPro2, Mevo, GC3, Trackman etc)

as an add-on camera club tracking system with full post shot club tracking video playback

VisTrak Eagle DIY price $699

Coming later this weekend:

More improvements to the IBS method of club detection.

I'm currently running tests with my library of over 500 shot videos

CP 64 update 10.2.7.4

New 1:

Club detection using IBS

Club detection without the requirement to apply white strips or other markings to the club

Often times the club face is not clear in the frames when using darker clubs without white strips on them.

The problem is resolved when using Image Background Subtraction (IBS)

There's still some more work to be done on this new feature but should be ready by next week.

How IBS works

IBS uses two images.

1. an image captured of the ball on the mat without a club ( the IBS reference image)

2. an image of the ball on the mat just before the club strikes the ball

After the shot, the two images are subtracted from each other which leaves an impression of just the club.

Assuming that the club image pixels have a different gray scale level than the underlaying mat pixels.

All club detection processes are then performed using this new club impression image instead of the original frame image.

 

New 2: Improved TM PIX ball spin detection

GSA Golf Objectives for 2025

My objective is to produce a ceiling mounted tracking system that equals the hi-priced systems (i.e. in the $6,000 to $14,000 range)

in features and accuracy for the super affordable price of just $1,699.

My latest ball spin detection feature - and now with the new IBS club detection feature - should put my systems on this path easily.

VisTrak SCX ball spin detection working best with Taylor Made Pix balls

Current test results show that the VisTrak SCX spin detection works best with the Taylor Made Pix balls

Main reasons are that:

1. In contrast to using the ball logo, no matter what ball in flight frames are used to calculate the spin, there are always 2 frames showing the Pix images

2. In contrast to launch monitor proprietary balls with spin dots on them (QED or Rapsodo etc) , TaylorMade Pix balls are readily available in any golf store for a regular ball price

CP 64 update 10.2.6.9

Fix : Occasional incorrect (too fast) ball speed reading when making chips and half shots with SCX systems

Fix : Occasional incorrect ball path reading with EVi systems

Many thanks

Many thanks to all my customers and readers who report issues and offer suggestions on how to improve the systems.

I can test my systems all day here without issues but there's always sporadic issues that can turn up that are very difficult to detect.

In particular I'd like to thank Phil (UK), Charles (Canada), Miyagi san (Japan), Frank ( Taiwan) and a host of others here in the US and around the world.

Coming next week

Status report of the new ability to detect ball spin using any or no marks on the ball.

CP 64 update 10.2.6.7

New 1: EVi side mounted Vcam - ability to detect ball when ball is only illuminated from above

New 2: when both the club and spin markings on the ball are not detected, back and side spin will be calculated from ball VLA, HLA and Speed .

Fix : Occasional incorrect ball speed reading (too fast) when making chips and half shots with EVi systems

January 24 1:20 pm

New ball spin detection method coming soon

Measuring Ball Spin from an overhead ceiling mounted camera

using image pixel shift and rotation matching methods

This method consists of taking an array of pixel levels of the ball image in 2 adjacent frames

and obtaining a match with a series of pixel shifting and rotation procedures.

Using this method, rotation (and thus back and side spin) can be detected even with just a smudge mark on the ball.

i.e. this method is not looking for any specific dots or markings on the ball

so any ball can be used as long as there's something on the ball that is not pure white.

January 21 3:00pm

CP 64 update 10.2.6.1

New 1: New settings in Setup Panel

1. Allow user speed adjustments.

Usually OFF.

2. Game Status Update ON/OFF

Usually ON but can be switched OFF if the 3 second update is causing issues.

Note that if OFF, then the CP will only show a 7 iron as the selected club in the game software.

As the CP doesn't require to know what club is selected in the game software, the CP's club selection can be ignored

New 2: More improved method of measuring side spin with SCX systems using spin dot balls

New 3: New customer camera registrations
