The invention discloses a monocular camera and millimeter wave radar external parameter calibration result accuracy evaluation method. A plurality of metal balls are arranged in a scene, after data information of the metal balls in all coordinate systems is converted, statistics and comparison calculation are completed, and four indexes describing the accuracy of an external parameter result are obtained, and two indexes are in a camera image plane and two indexes are in a radar point cloud space. 本发明公开了种单目相机与毫米波雷达外参标定结果准确性的评价方法，通过在场景中布置数个金属球，对金属球在各个坐标系下的数据信息进行转换后，完成统计与比较计算，得到了四种描述外参结果准确性的指标，其中两种在相机图像平面内，两种在雷达点云空间内。
