摘要
产品外形的3D测量与可视化是逆向设计中的重要环节,但是数据采集及可视化效率往往取决于产品外形结构的复杂程度.针对该问题,本文以管状工件为对象,利用激光位移传感器设计了3D测量系统,并基于产品外形尺寸突变信息,优化数据采集策略及插值方法,实现了产品3D外形的可视化.实验结果表明:本文优化的数据采集策略及插值方法,极大地提高了测量效率和可视化效率,相比于螺旋扫描提高了约2倍.
3D appearance measurement and visualization of workpieces are the important steps of reverse design. However, the efficiency of data acquisition and visualization depends on the complexity of the workpieces＇ appearance. So, for the tubular workpiece, this paper used the laser displacement sensor to design the system of 3D measurement. Also based on the mutation information of the workpieces overall dimensions, the strategy of data acquisition and interpolation method was optimized. Then the 3D appearance visualization of workpieces was realized. The result shows that the strategy of data acquisition and interpolation method in this paper improves the efficiency of measurement and visualization. Compared to the spiral scanning, the efficiency increases about 2 times.
