Hi Ersin, I tabulated al range of start, aim and final, the data resulting and combinatios are very interesting and it permitted me take several important conclusions. Yesterday I trained the Ersin´s plus system and the correlation betwen data and shots was great. I wil tell you more conclusions acording to my training. Fantastic and great system.
@ Ok Ersin, there is a lot to comment on, I will try to advance as I have conclusions. In relation to the formulas that you developed Ersin, just as you said it is necessary to have reference points or on the contrary be mathematically skilled, for my part it took me a long time to do the fine calculations that the Plus system requires, so I did the following to facilitate the process. First I tabulated the final results in relation to the outputs (start) 10, 15, 20...80 with the aim 0, 1, 2...30, I achieved a matrix of alternatives, I repeat this for effect (spin) 1, 2 and 3. Then I found another matrix with the value delta final minus satart, which allowed me to take reference points and do more reasonable and faster analyses. For example, for all aim 15 with spin 3, the delta finish minus start will always be 27, this with some small deviations, very sensitive in stars between 10 to 30 Another, for all aim 10 with spin 2, the delta finish minus start will always be 27, this with some small deviations. I apologize for going on too long, there are many other value analyzes based on Ersin's formulas, I can gladly share the excel file with anyone who requires it and we share the results and analysis.
Excelente video de sistema plus, me gusto demasiado pero lo quemas me intriga es el software con el que edita sus videos (trayectoria de las bolas) algun nombre del software?

Gracias ❤️. I make the routes with a software I have programmed.
Awesome video! Did you use HSV to detect the balls? I feel like the tracking accuracy can be improved more :)

Yes I use HSV to filter out the balls, but only that is absolutely not sufficient, since my head, hand and arm ate also vidible. So I have to play aoround eith constrast, gain, filter based on area, circumference, roundness and distance to ast detected position. And yet, dtill it is not working perfect. Main reasons are the changes due to motion blurr at high speed shots, the non linear distortion of the lens and the perspective distortion. After 2 years of trial and error, currently I am happy enough with the current state. Nowadays I am working on my Cue acceleration Sensor. Strugling with the programing in Python is killing me. Do xou have some expertise in GUI programming?

Hey @puboh you have made great videos. Also saw your tracking is really impressive. Read in some comments that you were using optical flow. I have checked the optical flow functions earlier, tried it but wasn't able to get out any thing useful. But when I saw your video now, I knew that it is possible with optical flow so I can do it. My trials today were interesting... It tracked the balls quite good, but somehow the detected position of the balls were shifting, depending on parameters of the optical flow function. If you don't mind, I would like to contact you to get some advice.
OpticalFlow doesn't work well with general video. That method works for my high speed video because the ball surface has a bright reflection spot. But HSV works well in general. I can send you my code if you want. How do i contact you?@
thanks. math is easy,, final number is understandable. but how to define the start/aim vector? I don't know how you come up with the start/aim number in each case. pls help.
First I guess using spin 2 a reasonable direction tangential to the 2nd ball, calculate where it comes on 3rd rail. Based on the difference to what is necessary I can adapt either direction by changing hit thickness, or I change spin +/-. Normally the first guess is may be off about 1 diamond, since I use aims and spins with easy numbers. The necessary adaptation then I just make by gut feeling. As always, biggest problem is to bring the ball in to the correct direction after hitting ball 2. Try whenever reasonable to use 1/2 ball hit and then 36 degree deflection.
