摘要

针对飞行试验机载环境下摄像机或镜头的抖动影响影像测量精度的问题,提出了一种机载影像测量消抖算法.通过在同一帧画面内将运动目标和固定不动的参考系加以区分,利用参考系内3个以上不动特征点采用空间后方交会算法逐帧解算摄像机的外方位元素,修正摄像机拍摄时刻的位置和姿态,消除或减小摄像机抖动对测量精度的影响.试验结果表明,该方法可使影像测量精度提升至毫米级,满足飞行试验数据精度要求.

Abstract

A algorithm for eliminating camera or lens's micro-shaking which affects measurement accuracy caused by aircraft's vibration during flight test was proposed, According to differentiating the moving target and stationary reference in the same frame, and then using 3 or more fixed feature points in the stationary reference of every frame to solve the camera's exterior orientation elements based on space re-section to correct the camera's pose.After that, the effect on measurement accuracy can be eliminated or reduced.The test results show that this method allows image measurement accuracy up to millimeter level, which meets the accuracy requirements in flight test.
