| 摘 要： | 航测相机像移补偿有两种方法 :一是在相机的焦平面上 ,使感光平面沿飞行方向 ,在曝光瞬间作一微小位移 ,以改正因摄影平台相对于被摄目标的运动引起的像点位移 ;二是在曝光瞬间 ,使相机作一微小的俯仰角旋转 ,以改正因摄影平台相对于被摄目标的运动引起的像点位移。前者简称为焦平面平移改正法 ,后者可称为俯仰旋转改正法。本文中研究了这两种像移补偿方法的差异和所能达到的精度水平及其适用范围

| Abstract: | There are two FMC(forward motion compensation) methods of aerial photogrammetric camera to correct the image displacement due to the relative motion between the photographic platform and objects at the exposure instant:1) On the focal plane of camera, the sensitive plane is moved a little in the direction of flight; 2) The camera is rotated a slight pitching angle. The first is simply called translational correction of focal plane, the second is called pitching rotation correction. The paper reveals the differences between these two FMC methods, their obstainable accuracy and applicable range. |
