【Abstract】 The 3D coordinate measurement is a key step in reverse engineering. The precision and usability of the measured key point affects the efficiency and effect of the model construction. The whole process of 3D coordinate measurement of auto fan from key point position design,jig location to data collection is discussed on the basis of the analysis about structure of the auto fan and requirement of computer assisted reverse design to the key point.更多还原
