| 摘 要： | 分析了航空数字相机像移的产生机理,提出了一种后推式像移补偿方法。搭建了航空数字相机的航拍仿真试验台,通过微米电机控制相机镜头反向运动的补偿速度和补偿量,实现后推式像移补偿。利用图像清晰度评价补偿前后的图像效果,补偿后像移残差值低于1/3像素。最后给出了后推式补偿方法与软件补偿方法的对比,结果表明,后推式补偿方法在补偿精度方面优于软件补偿方法,说明了该方法的可行性。 |

| Abstract: | The mechanism of image motion of airborne digital camera is analyzed and a method of the backward-push forward motion compensation is proposed. The aviation simulation test-platform of airborne digital camera is build to achieve backward-push forward motion compensation by use the micro motor to control the compensation speeds and compensation of camera lens countermove. The compensated remain image motion is less than 1/3 pixel by applying image clarity to evaluate the compensation effect. The method of the backward-push forward motion compensation is contrasted to software compensation method and the results show that the method of the backward-push forward motion compensation is superior to software compensation in the matter of the compensation precision. The method proposed is feasible. |
| Keywords: | airborne digital camera forward motion compensation (FMC) the backward-push image-clarity software compensation |
