曲面激光数字化测量数据误差的分析和处理

Error Analysis and Process of Laser Digitizing Measure Data for Curve and Surface

激光数字化测量因其测量速度快 ,适应范围广 ,在反求工程中获得了越来越广泛的应用 .由于测量过程中 ,测得的数据不可避免要受到各种随机测量误差的影响 ,影响到测量结果的准确性 .介绍的数据平滑处理方法 ,可以有效地减少这一误差 .

Laser digitizing measurement has been applicated in reverse engineering widely for its high measure speed and extensive applicable area.During the measure course,the measure data will be affected unavoidably by all kinds of errors,and the veracity of measure result will be affected.A kind of data smooth process method to reduce this kind of error will be introduced.
