Abstract

A system is described which acquires a depth map of an object using the stereo principle. The system consists of a matched pair of cameras, which are able to move, zoom etc. under computer control, enabling an entire inspection sequence to be performed automati-cally. The correspondence problem is overcome by projecting a controlled stripe of laser light onto the object, and then moving the stripe to obtain a series of images that are processed to give a dense depth map. The accuracy of this depth map and its limiting factors are discussed, with particular reference to the calibration procedure used and the components of the system.
