| 摘 要： | 针对现有线结构光传感系统标定过程中对设备要求高、标定过程繁琐等问题,提出一种基于三点透视模型的快速标定方法.引入一个可自由移动的平面靶标,靶标上只需要共线且相互位置确定的3个特征点,利用共线三点建立三点透视数学模型,根据3个特征点以及光条纹在摄像机像面的成像信息,获取了光平面上标定点在摄像机坐标系下的坐标.平面靶标在视觉范围内任意移动几个位置,得到光平面上多个标定点坐标,从而确定光平面方程.实验证明,该方法平均相对测量误差约为0.72%,标定时不需要昂贵的辅助调整设备,也不需要求解坐标系之间的转换矩阵,简单、快速,适合现场标定. |

| Abstract: | In order to solve the calibration problems in line structured light sensor systems such as requirements for high accuracy calibration models,complicate calibration procedures and so on,a calibration method based on perspective-three-points was proposed.A calibration model was established by introducing a planar target that could move freely with three collinear and known mutual location points.The calibration point coordinates in a camera coordinate system could be calculated by using the imaging informatio... |
