Abstract:
1. A system for the non-contact measurement of a surface of a complex part shape comprising: a support on which the part is mounted for holding the part in a predetermined fixed position; a large area optical sensor positioned so the part is substantially within the sensor's field of view at the distance from the sensor where the part is mounted on its support, the optical sensor measuring surface features of the part; positioning means on which the optical sensor is installed for moving the optical sensor over the surface of the part in a non-contact manner to locate surface features of the part in a co-ordinate system; a high resolution point sensor for locating and measuring the edges of the part, the point sensor also being installed on the positioning means and moved over the part in a non-contact manner to locate the edges of the part's surface; and, a processor processing the surface feature information and comparing the information with corresponding information from either a master part model or a reference part to determine acceptability of the part.
