    Abstract: 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.

    Abstract: In the field of man-machine interaction technologies, a gesture-based object measurement method and apparatus, which are used to improve measurement efficiency. According to this method, after image information is collected, contour information of a to-be-measured object is automatically extracted and partitioned off, and a measurement parameter value such as a length, an area, or a volume is calculated on this basis. In this way, not only real-time online measurement is implemented, a measurement process is simpler, and more convenient, visual, and effective, and augmented reality (AR) measurement efficiency can be improved, but also the measurement process is more harmonious and natural, and closer to a human intention, and a measurement result is more accurate.
