摘要
航空相机在拍照瞬间由于飞机的飞行运动和姿态变化而产生像移,要提高照相分辨率必须进行像移补偿。文章介绍了两种面阵CCD航测相机前向像移补方法,即旋转俯仰轴补偿法和面阵CCD TDI功能补偿法,计算了两种方法的像移残差及误差精度,给出了旋转俯仰轴方法的适用范围,对比了两种方法的优劣,通过实验室拍摄验证了方法的有效性。
Image motion is brought out in aircrafts＇ continuing flight and the change of gesture angles, so it is necessary to enhance the image resolution of the camera by image motion compensation （IMC）. Two forward image motion compensation methods for airborne area CCD cameras were introduced： rotating pitching axis compensation method and area CCDTDI function compensation method. The residual image motion and error precision of the two methods were calculated, and the applications of the rotating pitching axis were presented. The two methods are comparatively analyzed, and the effectiveness is verified experimentally in laboratory.
