Using a Raster Display for Photometric Stereo

This paper presents a new controlled lighting apparatus which uses a raster display device as a light source. The setup has the advantage over other alternatives in that it is relatively inexpensive and uses commonly available components. The apparatus is studied through application to shape recovery using photometric stereo. Experiments on synthetic and real images demonstrate how the depth map of an object can be recovered using only a camera and a computer monitor.
