Automatic Measurement System of 3-dimensional Coordinate Measuring Machine on the Basis of Image Processing

In Case of Workpieces Composed of the Combination with Rectangular Prisms

Abstract

The study presents the method of automatically measuring dimensions of unknown workpieces placed at an arbitrary position by use of a 3-dimensional coordinate measuring machine (3 D-CMM). To recognize the workpiece shape, the image processing technique is utilized. The recognition of workpiece shapes leads to the generation of measuring paths of 3 D-CMM. Though the workpiece shapes are limited to the combination with rectangular prisms, the method is found to have the potential of automatically measuring workpiece dimensions.
