Movement Analysis of Cue Sports

New to forum. Have previously used accelerometer to analyse a professional cue sports player. Anyone here or know of similar tech applied to cue sports.

Thanks

Lots of work has been done on cue control. It is all about speed and direction. Accelerometers are often used because they are easier to implement than velocity sensors, so the acceleration must be integrated…

Welcome! I´m sure you can do object detection/tracking, check OpenVINO

Lots of work has been done on cue control. It is all about speed and direction. Accelerometers are often used because they are easier to implement than velocity sensors, so the acceleration must be integrated to determine speed. If the mass of the cue equals the mass of the ball, the cue should stop on impact and the ball should acquire the speed of the cue, but of course the hand interferes with this relationship, as does the locus of impact.

Thanks. Snooker was my original purpose as pockets less forgiving and distances involved on large 12' x 6' table. Since my experiments many years ago now a few commercial products though on has had no chips for two years with next shipment in August. Has this impacted Engineering projects for anyone here. My original accelerometer was from Analog Devices via a development kit.

Had a quick search and no related projects. You are on to something as while the cue does the work the errors are in delivery all part of biomechanics. Elbow shoulder wrist head movements. Tension is a factor as in the pressure of competing and clutching jabbing as opposed to smooth timing. Did see some dot systems that use internal accelerometers and video calibration though for semi professional at $15k. Your idea though could work out cheaper and may even capture cue movement from video footage. So could record signature swings of professional players and compare to or copy for novices to learn. Timing appears a critical requirement for position control and importantly for eliminating sidemovement in the practice swings. Thanks for suggestions.
