摘要: 航空相机是对地勘查测量获取信息的重要设备,通常采用前向飞行结合翼展方向摆扫的方式来扩大航空相机视场。着眼于扩大视场带来的运动像移问题,进一步严格推导了飞行和翼展两个方向的像移补偿公式,提出了实用性较强的像移补偿方案。基于MATLAB/Simulink环境对像移补偿系统数学建模进行仿真验证,仿真结果证明了该补偿方案的可实现性。在硬件实验中采用FPGA芯片作为核心芯片,实现了设计方案中像移补偿的功能。实验和仿真结果曲线实现了较好的吻合,像移补偿效果图进一步证明了像移补偿是提高航空成像质量和分辨率必不可少的环节。

Abstract: Aerial camera is an important device on obtaining information by the method of air-to-ground investigation and measurement. The way of forward flight together with pendulum scanning in the direction of wingspan is commonly used for broadening the field of view of aerial camera. The problem of image motion compensation was focused on, which was produced by broadening the field of view. The image motion compensation formulas of the flight and wingspan direction were further derived, and the high practicability compensation scheme was proposed. Based on the MATLAB/Simulink environment,the mathematical model of image motion compensation was simulated and verified. Simulation results show that the compensation scheme is achievable. In the hardware experiment, the circuit which was mainly made of the FPGA chip was used to achieve the function of image motion compensation. The experimental and simulation result curves are in good agreement. The effect images further certificate that the image motion compensation is an indispensable link in improving the imaging quality and resolution.
