激光仿形的杂散点处理

Processing for Desultory Point of Laser Profile

针对数控激光仿形中出现的杂散点问题 ,提出了误差评定区域法。其基本思想是 :先找到有效数据段 ,利用误差评定区域原则找到杂散点 ,最后剔除掉杂散点 ,同时采用回朔法恢复有效数据点。并举例证明了此方法的有效性。

The article bring forward a viable means aim at the problem that desultory point exist in the laser profile data.We named the means is error assess area.The basic idea of it is finding a available data segment first,then using principle of error assess area to find desultory point weeding them and comeback the available data by retrospect at last.The ensample prove the validity of this means.
