摘要： A method for detecting a location of a laser point on a screen includes acquiring a first image frame captured by a first camera among N cameras; detecting whether a first laser point exists in the first image frame; and when the first laser point exists in the first image frame, and no laser point exists in an image frame captured by another camera except the first camera among the N cameras, using the first laser point as the laser point on the screen, and acquiring information about a location of the first laser point on the screen. In the present application, images captured by all cameras do not need to be fused first; instead, laser point detection is performed directly on a captured image frame. This greatly improves efficiency of the laser point detection and improves detection accuracy.
