Image calibration method and projector system that are able to automatically adjust a distorted image

摘要

An image calibration method includes determining a plurality of positioning devices on a projection plane, obtaining a plurality of coordinates of the plurality of positioning devices on the projection plane, and controlling a first projector to adjust a first raw image projected by the first projector to a first adjusted image that is framed at the plurality of coordinates. The first adjusted image is a polygonal image without the introduction of keystone distortion.
