The present invention provides a method and system for real-time projection of images in public places, which analyzes and processes captured environmental images of public places to determine the presence status information of people in public places and the range information of projectionable areas, and correspondingly obtains the corresponding information for image projection Projection position and projection area, and finally combined with projection position and personnel presence status information, adjust the projection resolution and / or projection contrast of the current image projection, so that image viewers in different areas can see clear and non-obvious images The projected image with poor deformation can effectively improve the automation and intelligence of image projection in public places.
Description
technical field [0001] The invention relates to the technical field of image projection, in particular to a method and system for real-time image projection in public places. Background technique [0002] At present, image projection is performed on a dedicated projection screen, and the projection screen has a large area and needs to be arranged on a corresponding plane to achieve high-quality image projection. However, in general public places, there are no dedicated projection screens to receive projected images, which can only project images on the corresponding blank wall areas in public places, and the positions of people in public places change frequently and the corresponding blank walls The surface area cannot match the projection location / projection area requirements, which puts forward higher requirements for high-quality real-time image projection in public places. The existing technology is in urgent need of a real-time image projection mode that can perform hi...
