Abstract
It is disclosed a method, and a device (10) capable of localizing ball impacts on a surface of an environment. Based on differences between any two consecutive video frames of the video, one or more blurs in the video are detected (704). Parameters of the ball are compared (706) with parameters of the detected one or more moving blurs. When the parameters being compared match, the moving blur for which the parameters match, is associated (708) with ball. Dimensions of the matching blur are determined (710). Based on a change in the dimensions of the moving blur, a ball impact is detected (712). Localizing (714) of the ball impact on a surface, is based on the change in the dimensions of the moving blur being associated with the ball, and environmental parameters. It is an advantage that localization of ball impacts does not require the ball to be continuously visible.
