WIPO Patent Application WO/2022/105277
Kind Code:
A1
Abstract:
The present invention relates to the technical field of image projection. Disclosed are a projection control method and apparatus, a projection optical machine, and a readable storage medium. The method comprises: acquiring a medium image captured when a photographing device performs image capture on a current projection medium; segmenting the medium image into multiple areas to be verified; automatically extracting, from the multiple areas, a maximum effective display area meeting a preset aspect ratio; performing conversion on an image to be displayed according to a corner position of the maximum effective display area in the medium image and an image mapping and conversion relationship between a projection optical machine and the photographing device, transferring the converted image to a projection area of the projection optical machine corresponding to the maximum effective display area, and obtaining a corresponding image to be projected; and directly controlling the projection optical machine to project said image. The invention enables the content of an image to be displayed to be quickly displayed in an area of the projection medium corresponding to the maximum effective display area and suitable for image projection, thereby improving image projection performance and image viewing experience of users.
