| 摘 要： | 为提高航空遥感相机的照相分辨率,必须对航空遥感相机进行像移补偿。探讨一种面阵CCD相机像移速度的计算方法——坐标变换法,其原理是利用地面上相同点在相机姿态变换前后像面不同坐标值之间的矩阵关系求出像移量及像移速度。利用该方法计算航空遥感相机在垂直工作方式下像面中心点与像面上任一点由于飞机的姿态变化与飞机的飞行运动引起的前向像移速度和横向像移速度,并将此方法推广到倾斜式相机像移速度的计算中。

| Abstract: | To improve the imaging quality and enhance the image resolution of the camera in photographing,it is necessary to compensate image motion(IM) which is brought out in airplane's continuing flight and altering airplane gesture angles including pitching angle,yawing angle and rolling angle.In this paper,the technique of converting coordinate system was applied to calculate the value of IM while the airplane was continuing flight and the gesture angles were changing.The value of IM and its velocity were calcula... |
