An automated CAD guided sensor planning process

摘要

A method of automatically determining one or more sensor locations for sensing a surface of a physical part includes a CAD model 12 and a sensor model 14. The CAD model 12, which is representative of the surface of the physical part, and the sensor model 14, which is representative of a 3-D image capturing sensor 22 are both input into a sensor planner 16. The sensor planner 16 subdivides the CAD model 12 of the physical part into a plurality of discrete partitions. The plurality of discrete partitions are then grouped into one or more subgroups based on visibility criterion. The sensor planner 16 then automatically outputs a set of viewing positions 18 and orientations for the sensor 22.
