Save my name, email, and website in this browser for the next time I comment. Our software then calculates the precise ball track in 3D space and predicts the path once the release, bounce and impact points are known. Remember that grid formation can also overlap. We have separated the white objects from the others. Ball-by-Ball Coverage.

Here is a demo of what we will be building in this article: The Ball Tracking System, as Im sure youve gathered by now, is a powerful concept that transcends industries. The ball-tracking technologies currently in use for the DRS - the Hawk-Eye and the Virtual Eye - are being tested by a company called Computer Vision Consulting Limited. With the help of ball tracking technology, we can analyze the raw videos and generate heat maps. We will read the frame and apply Gaussian blur to remove noise in an image: How to know the color of the ball, we can easily segment white objects in an image.
