Abstract

The invention relates to the technical field of projection, in particular to a projection method and device, projection equipment and a computer readable storage medium. The projection method providedby the embodiment of the invention comprises the steps of obtaining three-dimensional coordinate information corresponding to a plurality of preset original feature points in a test image in a worldcoordinate system; according to the three-dimensional coordinate information corresponding to the plurality of original feature points, obtaining a to-be-converted region meeting a projection requirement from the projection scene image; converting the to-be-converted region into a projection equipment space coordinate system according to a transmission conversion relationship of the projection equipment space coordinate system relative to a world coordinate system to obtain a target region; and projecting the target projection image to the target region. According to the projection method provided by the embodiment of the invention, the positioning process of the target region can be simplified, and the projection method can adapt to projection scenes with different complexity degrees.

Description

Technical field[0001]The field of projection technology of the present application, specifically, relates to a projection method, device, projection equipment, and computer-readable storage medium.Background technique[0002]A projection device, also called a projector or a projector, is an electronic device that can project image content onto a target area (for example, a projection screen area, a blank area on a wall, etc.). In the prior art, before the image content is projected to the target area through the projection device, the projection device needs to be manually adjusted manually to realize the reasonable positioning of the target area, and the entire adjustment process is relatively cumbersome.Summary of the invention[0003]The purpose of the embodiments of the present application is to provide a projection method, device, projection device, and computer-readable storage medium to solve the above-mentioned problems.[0004]In the first aspect, projection methods include:[0005...
