摘要
构建了由2个结构光传感器组成的激光视觉三维测量系统,建立了测量系统的数学模型。提出了一种基于未知运动的平面靶标获得测量系统全部参数的现场校准方法。实验表明,传感器校准后的三维坐标精度为0.011、0.008和0.115mm,所提出的校准方法无需依赖专门的三维测量设备,操作简单,促进了双传感器激光视觉测量系统的工程化三维测量应用。
A 3-D laser vision measurement system with double structured-light sensors is constructed and the mathematical model of the measurement system is established. By using unknown motion of planar target,a flexible approach to easily determine all the model parameters of the measurement system in site is proposed. The real experiments show that the threedimensional coordinates RMS errors are 0. 011 rnm,0. 008 mm and 0. 115 mm in calibration case respectively. The experimental results also show that the proposed calibration method can be performed in site without special three-dimensional measurement apparatus and elaborate setup. The method advances double sensors laser vision measurement system from la boratory environments to real engineering three-dimensional metrology applications.
