The paper proposes a computer-aided 3-dimensional shape measuring system which consists of 5-directional measuring machine installed with a newly developed non-contact distance sensor, and processors provided to transform the measured distance data to coordinates then also to construct entire mesh point data of the object workpiece. The distance sensor is based on an astronomical telescope typed optical system, equipped with laser tube and one dimensional CCD set horizontally on the optical axis. The device has following features : (1) wide range of measuring distance, (2) high measuring rate, (3) linear measuring characteristics, (4) less hidden effect and (5) compact size. The system is one of the sub-systems in a more comprehensively computer-aided marking system which, also having been realized in the same period, executes automatically all processes concerning to marking operation for large sized workpiece produced by casting and/or forging. Some test results of the measurement are presented constructing mesh point data model of the entire surface for a few typical workpieces.
