Abstract
Systems and methods for detecting a mark left by an object on a playing surface are provided. A system for detecting a mark left by an impact of an object on a playing surface, the system including at least one processor coupled to a memory arrangement. The system may further include at least one camera for collecting a sequence of images of the playing surface before and after impact of an object. Additionally, the system may include an image processing system adapted to process at least a portion of the sequence of images to identify the mark left by the object on the playing surface. The system may also include a judgment processing system operative to determine the position of the mark relative to the feature of the playing surface.
