Correction method and device for multi-optical-machine projection image and multi-ray machine projector

Abstract

The embodiment of the invention relates to the technical field of multi-optical-machine projection, and particularly discloses a correction method and device for a multi-optical-machine projection image, a multi-optical-machine projector and a readable storage medium. The method comprises the steps: acquiring a projection picture area of each optical machine; calculating coordinates of four angular points of an overlapping region of projection picture regions of all optical machines and a projection picture conversion relational expression of each optical machine; reversely converting the coordinates of the four angular points of the overlapping area to the projection coordinates of each optical machine to adjust the projection coordinates of each optical machine, so the projection imagesof the multiple optical machines can completely coincide with the projection images of the multiple optical machines, the projection brightness is improved, the assembly precision requirement of the projector with the multiple optical machines is not high, and the projector is suitable for wide popularization.

Description

technical field [0001] The present invention relates to the technical field of multi-light machine projection, and in particular to a correction method and device for multi-light machine projection images, a multi-light machine projector and a readable storage medium. Background technique [0002] The existing methods of calibrating dual-optical projection are based on two separate projectors, and then use an external camera to calibrate. The whole system is complex and difficult to operate, with many devices and not portable, so it has been used in professional fields and cannot Promote widely. At present, there is no method for correcting the projected image so that the projection images of multiple optical machines can completely overlap with two or more optical machines on one projection device. Contents of the invention [0003] In view of this, the present application provides a method and device for correcting images projected by a multi-light machine, a multi-ligh...
