Title:
PROJECTION METHOD, APPARATUS, AND DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/088419
Kind Code:
A1
Abstract:
A projection method, apparatus, and device, and a computer-readable storage medium. The projection method comprises: obtaining three-dimensional coordinate information corresponding to a plurality of preset original feature points in a test image in a world coordinate system (S100); according to the three-dimensional coordinate information corresponding to the plurality of original feature points, obtaining, from a projection scene image, a region to be converted which meets a projection requirement (S200); converting said region into a projection device space coordinate system according to a transmission conversion relationship of the projection device space coordinate system with respect to the world coordinate system so as to obtain a target region (S300); and projecting a target projection image to the target region (S400). The projection method can simplify a positioning process of the target region, and can also adapt to projection scenes having different complexity levels.
