Problems solved by technology

For another example, when the surface of the imaging medium is uneven (for example, the projection screen is bent or there are depressions and protrusions on the wall), the projection image projected by the projection device on the imaging medium may be distorted, and this distortion is random. and unpredictable

Abstract

The present disclosure relates to a projection correction method, device, storage medium, and electronic equipment, and relates to the field of projection technology, including: projecting a correction image onto an imaging medium to obtain a projection correction image displayed on the imaging medium, acquiring and collecting the image, and determining acquiring the first position information of each second marking pattern in the image, and determining that the projection correction image is formed in the acquired image according to the first position information of each second marking pattern and the second position information of each first marking pattern According to the first boundary, the target projection area on the imaging medium is determined according to the first boundary, and the image to be projected is projected onto the imaging medium according to the target projection area, so as to display the information contained in the image to be projected in the target projection area. The disclosure can ensure that no distortion occurs when projecting an image to be projected onto an imaging medium, can obtain a projection effect that meets user requirements, does not require manual adjustment by the user, is simple to operate, and has high efficiency in correcting projection.

Description

technical field [0001] The present disclosure relates to the technical field of projection, and in particular, to a projection correction method, device, storage medium and electronic equipment. Background technique [0002] In order to meet people's viewing needs for large-size screens, projection devices are widely used in homes, offices, schools and entertainment venues. The projection device may project onto an imaging medium to display a corresponding projected image on the imaging medium, where the imaging medium may be, for example, a projection screen, a wall or a hard screen. However, when the projection device projects onto an imaging medium, the projected image may be distorted, which will affect the projection effect of the projection device. For example, for short-focus or ultra-short-focus projection equipment, due to the limitations of the design process, processing technology and assembly process of the projection light machine, the projection image projecte...
