摘　　要：对双目视觉测量方法进行了研究和分析,采用张正友平面法对相机进行内外参数标定,根据标定所得参数对立体图像对进行校正和匹配,测距实验结果表明,在目标距离为112 m的静态条件下,该方法测量误差在5%以内,能满足一定场合的非接触测量需求。最后对影响双目测量精度的主要因素进行了分析,指出了进一步优化和提高双目系统测距精度的方向。Binocular vision measuring methods are demonstrated,ZHANG＇s camera calibration method is used to acquire both intrinsic and extrinsic parameters of cameras,followed by the rectification and matching of stereo images. The experiment results show that the ranging error is below5 % for a static target at 112 m,which could meet the need of some non-contact measurement occasions. Finally,factors that undermine the measuring precision are analyzed,and the heading of precision optimization as well as improving is indicated.
