A method includes projecting an image onto a projection surface through a projection lens of a projector, where the image comprises a fiducial marker. The method also includes capturing a point cloud of the fiducial marker with a camera, and generating a distortion map of projection lens distortion based at least in part on the point cloud. The method also includes generating a correction map for the projection lens, and applying the correction map to a video signal input to the projector.
