Problems solved by technology

However, this correction method not only requires the user to repeatedly debug, but also cannot guarantee that the keystone distortion will be completely eliminated, so that the user can obtain the best viewing effect
[0003] Although with the emergence of keystone correction technology, although related projectors can also achieve automatic correction, the existing correction methods are usually only designed for long-focus and short-focus projectors. For ultra-short-focus projectors, due to When an ultra-short-throw projector projects an image, the projected light has a large upward angle, so the existing keystone correction technology has limitations

Abstract

The invention relates to a projector correction method and system, a storage medium and electronic equipment, and relates to the technical field of projection, and the method comprises the steps: determining the offset information of a projector relative to a projection plane, and determining the two-dimensional imaging vertex coordinates of a projection image, projected on the projection plane, of an original image according to the offset information; correcting the scale of the original image according to the two-dimensional imaging vertex coordinates of the projection image to obtain the corrected scale of the original image; and controlling the projector to project according to the corrected scale of the original image. The beneficial effects of the present disclosure are that the keystone distortion generated by the projector in the projection process can be automatically corrected through the offset information, and the correction method can quickly and accurately determine the two-dimensional imaging vertex coordinates of the projection image, so that accurate keystone distortion correction is performed on the projector, and the accuracy of the projection process is improved. Therefore, the projection picture watching effect of the user is improved.

Description

technical field [0001] The present disclosure relates to the technical field of projection, and in particular, to a projector calibration method, system, storage medium, and electronic equipment. Background technique [0002] When the projector projects the image picture onto the projection plane (curtain or wall), due to the relative positional relationship between the projector and the projection plane, the image picture displayed on the projection plane appears trapezoidal distortion. Usually, the user can correct the trapezoidal distortion by manually adjusting the relative positional relationship between the projector and the projection plane. However, this correction method not only requires repeated debugging by the user, but also cannot guarantee that the trapezoidal distortion can be completely eliminated, so that the user can obtain the best viewing effect. [0003] Although with the emergence of keystone correction technology, although related projectors can also...
