Abstract

The invention discloses a dynamic projection method and system. The method comprises the following steps: performing projection in a photographed area; detecting whether a picture in the photographedarea moves or not; stopping projection when detecting that the picture in the photographed area moves; and performing re-projection according to the picture in the photographed area after detecting that the picture in the photographed area returns to be static. According to the technical scheme, whether the picture in the photographed area moves or not is detected, the action of the projector is stopped when the picture in the photographed area moves, and finally the problems of smear occurring during tracking projection or jamming delay caused by insufficient projection frame rate and the like can be avoided.

Description

technical field [0001] The invention relates to the field of optical analysis and design, in particular to a method and system for acquiring an object area through a real-time camera and projecting a picture of the object area. Background technique [0002] The existing video shooting and interactive fields, combined with efficient computing processors, can directly process and calculate superimposed images on the captured images in real time, and perform mixed and superimposed display through the projector. This solution may cause the following situations when the area to be filmed is translated, such as the movement of the projected picture causing discomfort to the user’s eyes, or glare or smear caused by insufficient frame rate of the projected picture. If certain technical means can be used to solve the problem The image translation of the region and corresponding feedback can solve the above problems to a certain extent. Contents of the invention [0003] For this r...
