Abstract

Three-dimensional computer vision can be useful in applications like gauging and inspection of shapes. In this paper an approach for model-based shape inspection of large objects using active 3-D vision is presented. The 3-D vision sensor developed is based on the direct measurement of the time-of-flight of a laser pulse. Inspection software, including methods for comparison of the acquired shape information to a CAD model, is described. Results of preliminary tests are reported.
