改良点云过滤技术在汽车冲压件逆向中的应用

点云数据一般是由非接触式三坐标测量系统获取,得到的结果需要进行点云过滤.由于一般扫描的点云数据量比较大,单是过滤点云就要化费大量的时间.为此利用点云数据过滤原理,并结合逆向工程设计软件Image ware与设计软件CATIA,改进了原来的过滤技术,缩短了逆向设计的时间,提高了工作的效率.

Application of improved data cloud filtered technology in automation pressing parts reverse engineering

Data cloud is obtained from the non-contact three-coordinates measuring machine usually,but the result must be filtered.,wuich cost much time because so many points to filter.Now by taking advantage of the filtering data cloud principle and the reverse engineering software Image ware and CATIA,the old filtering technology is innovated,the time spent on the reverse design is shorten clearly and the result sound much efficient.
