零件测量位置对光栅投影测量精度的影响
摘要
从原理上分析了光栅投影法测量的误差产生原因
并通过不同的测量方法对风机叶片的同一块表面形状进行了测量
比较各种测量方法之间的误差情况
验证了拍摄中心位置所测得的点云数据与被测物体在远离拍摄中心的情况下
偏离距离越远
其绝对偏差越大
点云数据也更加离散。
Abstract
This paper analysis the principle cause of errors in the grating projection method.The same position of a fan blade measured by different measurement ways and compare those different error situation of different experimental data to verify a conclusion that-The cloud point data measured away from the camera center
