摘要
针对空间坐标对图象平面坐标的非线性光学映射关系 ,本文提出了逐步逼近实现 3- D空间坐标计算的测量方法。该方法对摄象机的摆放姿态与双目传感器的装配精度要求较低 ,可去除介质折射产生的坐标计算误差。结合局部标定法 ,对摄象机光学系统的畸变误差进行校正。实验数据表明 ,在对双目传感器不提出较高要求的测量条件下 ,测量结果令人满意。
Aiming at the nonlinear optical mapping between spatial coordinates and image plane coordinates,a measuring method for 3 D spatial coordinates calculation carried out with progressive approach is put forward in the paper.The method has low requirements for the placement attitude and assembling accuracy of binocular sensor,thus the calculation error of coordinates produced by medium refraction can be removed.Combining with local calibration,the distortion error of the optical system in the camera is corrected.The experimental data show that without higher demands are proposed for the binocular sensor,the measured results are satisfied.
