| 摘 要： | 航空拍摄时,由于飞机与地面景物存在相对速度等原因的存在,发生像移是难免的。为了提高航拍图像的成像质量及相机分辨率,大面阵数字航测相机设计开发了像移补偿装置。采用了由步进电机驱动凸轮机构从而推动CCD平动的像移补偿方法。依据相应的补偿原理,得出航拍过程中的理论像移量。经过航拍实验验证,设计的补偿装置实际补偿后的地物位移量小于1/3像元。

| Abstract: | It is inevitable to bring image motion during aerial photography because of the existence of relative speed between plane and ground scenery and other factors. In order to improve imaging quality of aerial photography image and camera resolution, large resolution digital aerial survey camera designed image motion compensation device, and adopted the way that the step motor drove cam machine to push CCD. According to corresponding compensation theory, image motion value is educed in the course of aerial photography. Aerial photography experiments show that ground matter displacement quantity is less than one third pixel after compensation. |
