Projection correction method and device, storage medium and projection equipment

Abstract

The invention relates to a projection correction method and device, a storage medium and projection equipment, and relates to the technical field of projection, the method comprises the steps that a feature image is projected to a target projection area, a shot image of the target projection area is acquired, and the feature image comprises scale marks distributed in an image preset area; on the basis of scale marks of a projection picture in the shot image, a target picture area is determined in the shot image, and the target picture area is an area where the feature image in the modulation plane is mapped on the shot image; and correcting the projection image on the modulation plane based on the target picture area. Therefore, the method not only can significantly improve the speed of projection correction, but also is suitable for a target projection area of a single plane, and is also suitable for a target projection area of a complex multi-plane. And meanwhile, the corrected image can conform to the viewing angle of the user, so that the optimal projection viewing experience is provided for the user.

Description

technical field

[0001] The present disclosure relates to the field of projection technology, and in particular, to a projection correction method, device, storage medium, and projection equipment. Background technique

[0002] With the popularization of dynamic projection devices and rotatable projection devices, when users use dynamic projection devices or rotatable projection devices, projection pictures are often projected on complex three-dimensional surfaces. For example, complex solid surfaces such as yin and yang corners of walls and ceiling corners.

[0003] In the related art, facing the application scenario where the projected picture is projected on a complex three-dimensional surface, the picture is generally encoded according to the projected structured light of the projection device, and then the projected picture is encoded according to the distorted image of the current projected picture and the pre-calibrated encoded picture. Make corrections. However, thi...
