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.
