为了保证双目相机标定精度的同时,提高算法速度。利用田字形模板中的两对正交消隐点,拍摄两幅图像,实现快速标定。首先,提出了消隐点寻优的方法来提取每幅图像中误差最小的两对正交消隐点,线性计算相机主点和归一化焦距,作为内参数的初值。再根据同一幅图像消隐点共线和所有直线畸变后也为直线的原则,构建约束函数,利用优化的差分进化算法进行全局寻优,完成相机畸变校正。最后,根据优化后消隐点坐标求得左右相机的旋转矩阵,并结合左右相机的角点世界坐标,利用刚性变换求得平移向量。双目标定的平均重构误差为0.598 pixel,跟传统方法标定误差相当。该标定算法重构误差与传统算法在一个级别,能满足标定中稳定可靠、精度高、抗干扰能力强等要求。
In order to realize fast and accurate binocular calibration
two pairs of orthogonal vanishing points product from square template were used. This method requires only two images. Firstly
two pairs of orthogonal vanishing point were extracted from each image; secondly
winner point and focal length on each single camera were solved by linear algorithm; thirdly
considering the radial lens distortion
distortion correction was implemented by linear constraints. During this process
the optimization differential evolution algorithm was proposed. Parameters within the solution were set as initial value. Line collinear features were set as constrained optimization parameters. According to the coordinates of 4 vanishing point
by using the infinite homography matrix rotation orthogonal constraint
the initial values of the rotation matrix can be obtained and more accurately calculated rotation matrix can be obtained by the iterative method. Experimental results indicate that the reconstruction error is 0.598 pixel. The experimental results show that the calibration method can meet the precision requirements
and it is stable and reliable
high precision and strong robustness for self calibration.
