I want to do a project, which will consist in detecting possible collision of the pool balls, using opencv, webcam and C++ programming language. For now I just want to prediction collision of 2 balls on minibilard table. I detect them by change rgb to hsv and then use thereshold, in future i will probably use another method for detect a random amount of balls, but it's not so important now.
So, for now I can detect two balls, i know their position, radius, now I'm thinking how to predict whether there will be a collision between them, if we if we assume that they will move in straight lines. I think that I should check their position in every frame update (and i have to know a time between frames in my webcamera) and by that, i I will be able to determine the value of speed, acceleration and direction of the ball. So, if i will know those parameters for for both balls, I will be able to determine where can they collide, and then, using parametric equastion I will be able to check, if they will be on collision point on the same time.
I wonder if this is the right approach to the problem, maybe there is a simpler and more effective method to do this?
Thanks for any kind of help.
