Abstract

The invention discloses a projection method and device, projection equipment and a computer storage medium. The method comprises the following steps: projecting a specified image to an area where a curtain is located; the specified image comprises a closed pattern formed by lines; acquiring a scene image of the specified image projected in an area where the curtain is located; determining a first homography matrix capable of converting the scene image into the specified image based on the specified image and the scene image; extracting the contour of the curtain from the scene image; determining a target area, corresponding to the specified image, of the curtain based on the contour and the first homography matrix; and carrying out preset correction processing on the to-be-projected image based on the target area to enable the to-be-projected image to coincide with the target area, thereby realizing automatic matching of the projection picture of the to-be-projected image with the contour of the curtain by automatically adjusting the size of the to-be-projected image, and enabling the use of the projector to be more intelligent and convenient.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a projection method, an apparatus, a projection device, and a computer storage medium. Background technique [0002] A projector is a device that projects images or videos onto a screen. When using a screen for projection, the user is usually required to manually adjust the size of the projection screen to make the projected screen fit the size of the screen. The process of using the projector brings great inconvenience. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a projection method, device, projection device, and computer storage medium. By automatically adjusting the size of the image to be projected, the projected image of the to-be-projected image can automatically match the outline of the screen, so that the projector can be used more intelligently and convenience, improving the user experience. The technical...
