摘　　要：三坐标测量是逆向工程的关键环节,测量数据点的精度与可用性直接影响建模的效果和效率.在分析轿车风扇结构特点、考虑计算机辅助反求设计对点的要求的基础上,介绍了轿车风扇从特征点位置设计、装夹定位到数据采集的三坐标测量全过程.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.
