Structured light vision systems provide a practical solution to many 3‑D inspection problems. This paper examines the trade‑offs involved in designing 3‑D inspection systems that use triangulation. The authors derive general equations for triangulation‑based 3‑D inspection, describe a multistripe implementation, and analyze common structured‑light problems with proposed alternatives. Experimental results from a prototype system are presented.
Structured light vision systems offer a practical solution to many 3-D inspection problems. This paper examines the trade-offs involved in the design of 3-D inspection systems that use triangulation. General equations describing the behavior of such systems are derived. The implementation of a multistripe system is discussed. Problems common among structured light systems are explored, and alternative solutions are suggested. Experimental results from a prototype system are presented.
