In this project, we calculate the spin rate of baseball using high speed camera. A simulation of baseball is used in animation software blender to generate different spin rateaxis,then the balls fetched from the games are analyzed to match the simulation balls in blender using machine learning algorithms. The result is promisingspin rates can now be calculated with high speed cameras.

"With the simulation ball in blender, we can match the balls in real world from any angle, with changing of the simulation camera in blender. The camera can be at the back of home plate, at the side,45 degree,any other degrees. 
 The algorithm can be run on iPhoneany other smartphones, only thing needed is the angle of the shooting camera/phone to the virtual line between pitching platehome plate. This brings big convenience, lower the cost,has greater changes to be used by players."

This can be used on baseball, golf, tennis,any balls that have patterns on them to be matched,the spin rate is meaningful to the coachesthe players.
