通过在位于机身下方的吊舱中安装两台高速摄像机,从不同方向拍摄由机翼携带并随机翼运动的机载**,并对采集到的序列图像进行处理,获得了机载**在投放发射阶段的三维运动姿态参数。为了提高系统的测量精度和可靠性,首先对每个摄像机采集的图像进行单目摄像测量获得各自独立的运动姿态参数,再利用双目摄像测量算法同时处理两个摄像机采集的图像再次获得运动姿态参数。理论分析和实验结果表明该系统角度测量精度优于0.1°,位移测量精度优于0.5 mm,满足机载**投放发射阶段的测试需求。

Key parameters of airborne weapon such as 3D velocity and 3D pose can be acquired by processing images taken by two high speed cameras mounted in the cabin,which is fixed under the fighter plane. In order to improve the precision and reliability of the video-metric system,a new design based on monocular and binocular video-metric is realized separately. Theory and measurement results show that the angular accuracy of this system is prior to 0.1 degree and its displacement accuracy is prior to 0.5 mm,which achieves the testing requirement in airborne weapon bombing/launching period.
