一种双正交消隐点的双目相机标定方法
Binocular self calibration using two pairs of orthogonal vanishing points
摘要
Abstract
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 dis-tortion,distortion correction was implemented by linear constraints.During this process,the optimi-zation 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 coor-dinates 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 require-ments,and it is stable and reliable,high precision and strong robustness for self calibration.关键词
