摘    要:与基于交比不变性求解特征点坐标来标定激光平面的方法不同,本文提出了一种可适用于未知环境的线结构光三维视觉传感器现场标定的新方法,该方法只需简单几何知识,就可直接利用几何方法实现快速标定。通过拍摄一个与线结构光相交并以不同姿态随机自由移动的平面靶标的图像(至少三幅),就可同时实现三维视觉传感器CCD和激光平面的快速标定。该方法方便,快捷,简单,可实现自动化,标定精度高。实验结果证明了该方法的方便和有效性。

关 键 词:线结构光  几何法  标定

Abstract:Compared with traditional cross-ratio invariance approach by solving three-dimensional coordinates of intersection points to calibrate the laser plane,this paper presents a new method for structured light vision sensor calibration.The proposed approach only needs little mathematical knowledge,it can directly use laser intersection line image to calibrate the system.Through photographing image of the randomly moving target plane intersected by the laser plane(at least 3),the vision system calibration can be ...
Keywords:Line structured light vision sensor  Geometric method  Calibration
