SYSTEM, PROGRAM PRODUCT, AND RELATED METHODS FOR REGISTERING THREE-DIMENSIONAL MODELS TO POINT DATA REPRESENTING THE POSE OF A PART

摘要

A system (30), program product (39), and method to perform automated three- dimensional image registration of a part (43) within an inspection cell (49), are provided. The system (30) can include a laser-ultrasound inspection device (31) having a scanning head (61) to generate ultrasonic surface displacements in a part (43), an inspection laser (55), and an interferometer (59) to collect phase modulated light reflected by the part (43). The system (30) can also include a part position locator (33) positioned to measure a distance between points on a surface of the part (43) and a scanning laser reference location. The system (30) can also include a database (45) containing computer-aided design models (41) for each part (43) of interest, and a model (47) of the inspection cell (49). The system (30) can further include a laser ultrasound inspection computer (35) communication with the laser-ultrasound inspection device (31) and the part position locator (33), and laser ultrasound inspection program product (39) adapted to perform automated three-dimensional image registration of the part (43).
