We present a method for obtaining three-dimensional and large size parts information by CCD （Charge Coupled Device）, illustrate the mechanical structure and software composition of this system, and introduce image processing for extraction and synthesis of crankshaft measurement information. With the information obtained from image processing, geometric dimensions and tolerances of the crankshaft of different angles can be determined precisely and rapidly. In this way the goal of crankshaft measurement is achieved. This method settles the difficult problem of visual angle and precision of the three-dimensional and large size parts, expands the CCD detecting application field and provides a new way for other crankshaft parts measurement.
