The quality of industrial products is gradually increasing. In the same time, products and their parts most often have complex geometry which has to be described accurately by thousands or millions of measurement points. One of the most important quality control requirement is dimensional object to reference model consistency condition. Actually, large-size production process, especially in airplane, car and power industries, requires more effective measurement techniques. These new methods should introduce faster measurement speed and simultaneously high accuracy. In the paper we present a concept that combines the accuracy of coordinate measurement machines (CMM) and the speed of full-field optical methods. We present a model of opto-mechanical measurement machine (OMMM) based on the integration of an optical measurement system with a CMM. To minimize measurement time, the following sequence is proposed: optical measurement of whole surface, data analysis, contact re-measurement of critical object's areas and final metrological characterization. To prove correctness of the OMMM idea a laboratory prototype had been constructed. In the paper some experimental results of car body measurement are presented with uncertainty sources discussion.
