发明名称 High-speed, 3-D method and system for optically measuring a geometric dimension of manufactured parts
摘要 A high-speed, 3-D method and system for optically measuring a geometric dimension of manufactured parts such as cartridge cases are provided. The method includes consecutively transferring the parts so that the parts travel along a path which extends to a vision station at which each part has a predetermined position and orientation for optical measuring. A line of radiation having a predetermined orientation is projected onto spaced apart end surfaces of the part to obtain reflected line segments of radiation from the end surfaces of the part. The reflected line segments of radiation are detected at one or more image planes to obtain electrical signals and the electrical signals are processed to determine the geometric dimension such as primer pocket depth.

主权项 1. A high-speed, 3-D method of optically measuring a geometric dimension of a plurality of manufactured parts, the method comprising: consecutively transferring the parts so that the parts travel along a path which extends to a vision station at which each of the parts has a predetermined position and orientation for optical measuring, each of the parts having an exterior end surface and an interior end surface at a first end of each of the parts, the first end of each of the parts having a length and a width, each of the parts having a part-holding pocket extending from the exterior end surface to the interior end surface, the part-holding pocket having a depth defined between the exterior end surface and the interior end surface; projecting a line of radiation having a predetermined orientation onto the end surfaces to obtain reflected line segments of radiation from the end surfaces of the part; detecting the reflected line segments of radiation at one or more image planes to obtain electrical signals; and processing the electrical signals utilizing a depth algorithm to determine the depth of the part-holding pocket between the exterior end surface and the interior end surface.
