摘要

The invention relates to a method for determining the point of impact of a ball in a playing field during a controversial piece of play in a sports event and comprises the steps of: recording the contentious area during the game by means of a single camera, extracting the images corresponding to the controversial piece of play, selecting the area corresponding to the ball, calculating the coordinates of the ball in pixels in each image, determining the point of intersection of the two straight lines joining the previous points and transforming the point of intersection into real coordinates. As a result of these steps it is possible to resolve the controversial piece of play with a single camera and without the aid of accessories such as radar signals, electric signals, etc.
