Abstract
Disclosed is a projector keystone correction method, including: obtaining first coordinate values of a plurality of position points on a projective plane through an RGBD (Red, Green, Blue-Depth) camera in a first coordinate system; determining second coordinate values of the position points according to a predetermined conversion relation and the first coordinate values in a second coordinate system; and using an included angle between a fitted plane obtained by fitting according to the second coordinate values of the plurality of position points and a coordinate plane of the second coordinate system to achieve keystone correction.
