摘　　要：目前水中靶场尚无手段在较大范围内对目标结构塑性形变实施快速、高精度测量。以2台大恒千兆相机和自制标定板为基础,搭建了双目光学测量技术验证平台,在实验室条件下对点云拼接实测,对实测数据结果进行了分析,得到了有效的精度结论并分析了影响测量精度的主要因素。For the shooting range,there is no means to carry out fast and high-precision measurement for plastic deformation of target structure in large range at present.On the basis of2gigabit cameras and a self-made calibration board,the validation platform for binocular optical measurement technology is constnited to test,point cloud registration in laboratory conditions.Through analysis on the test data results,the effective accuracy conclusion is obtained,and the main factors affecting measurement accuracy are analyzed.
