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通过像移补偿来实现;在分析垂直拍照的面阵CCD相机像移产生原因基础上,确定了采用稳定平台与面阵CCD的TDI相结合的像移补偿方法,理论上计算了像移补偿后的像移残差小于3μm(即1/3像元),满足成像质量要求;根据实际的成像试验,证明文章论述的面阵CCD像移补偿技术是正确可行的。
Because that the image motion is brought out in aeroplane＇s continuing flight and the change of airplane gesture angles including roll, pitch and yaw, it is necessary to enhance the image resolution of the camera in photographing by image motion compensation （IMC）. Based on the analysis of image motion reasons of area scan CCD camera, the camera uses a IMC method of three axis gyro body sta- bilized platform in conjunction with the TDI of area scan CCD. According to analysis, the remain image motion with IMC is less than 3 μl and this meets the desire to image quality. The real experiments prove that it is an efficient method of IMC.
