Technology of the On-field Calibration of a Stereo-visual Sensor Based on the 3-D Measuring Model

提出了基于双目立体视觉传感器三维(3 D)测量模型的传感器现场标定技术,并建立了标定数学模型。相关实验表明,这种标定方法简单,具有较高的标定精度,最大尺寸测量误差小于0.05mm,对标定环境及靶标的摆放姿态无严格要求。

The method of on-field calibration of stereo-visual sensor based on its three-dimensional (3-D) measuring model was presented, and its mathematical model was established. The solution was proven by experiments to be easy and has high precision whose maximum dimensional measuring errors are less than 0.05 mm and with less demands for calibration environment and the posture of target.
