Range-image-based method and system for automatic sensor planning

摘要

A system (10) for measuring one or more dimensions of a physical part (18) includes a fringe generator (14) for projecting a fringe pattern of light onto a surface of the physical part (18) to be measured. The system (10) includes a sensor (12) for capturing images of the fringe pattern on the surface. The sensor (12) and the fringe generator (14) are located at different positions. The fringe generator (14) and the sensor (12) are each in communication with a computer (16) to determine whether each of the fringe generator (14) and the sensor (12) have line-of-sight visibility to the surface to be measured.
