| 摘 要： | 应用多个激光点结构光传感器对大尺寸工件横断面进行扫描，形成多个光切平面；拟合各个光切面上离散点为空间椭圆曲线，求出光切面中心的空间三维坐标，由此确定大尺寸工件轴线的直线度，并计算出横截面几何形状。提出了一种大尺寸工件直线度激光视觉测量方法，推导了数学模型，进行实验研究并给出实验结果。

| Abstract: | Several light incisions are formed when the large size part is scanned along the cross-section by laser light structure sensors.Since discrete points of each light incision are fitted to elliptic curve,the 3D coordinates of the center of the light incision plane can be attained.And with the space line fitting and error examination arithmetic,the large cross-section part's straightness is obtained.This paper puts forward the method and mathematical model of the measurement of the large-size part's straightness by laser vision,with experimental results presented. |
