Title:
PROJECTOR CORRECTION METHOD AND SYSTEM, AND STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/193558
Kind Code:
A1
Abstract:
The present disclosure relates to a projector correction method and system, and a storage medium and an electronic device, and relates to the technical field of projection. The method comprises: determining offset information, relative to a projection plane, of a projector, and then determining, according to the offset information, two-dimensional imaging vertex coordinates of a projected image of an original image that is projected onto the projection plane; according to the two-dimensional imaging vertex coordinates of the projected image, correcting the scale of the original image to obtain the corrected scale of the original image; and controlling the projector to perform projection according to the corrected scale of the original image. The beneficial effects of the present disclosure are: a keystone distortion, which is generated during a projection process of a projector, can be automatically corrected by means of offset information, and by means of the correction method, two-dimensional imaging vertex coordinates of a projected image can be quickly and accurately determined, so as to perform accurate keystone distortion correction on the projector, thereby facilitating the improvement of a picture effect of a projection viewed by a user.
