摘要
介绍了捷联式行扫图像畸变机理与矫正方法。捷联式行扫仪与平台式行扫仪相比,有很多优点,但载机姿态角扰动运动时引起图像畸变而影响目标识别。研究捷联式行扫图像畸变产生机理,建立了行扫图像畸变矫正的反向数学模型,提出了一种行扫图像畸变矫正算法,并在VC环境下编写矫正软件。仿真结果表明该行扫图像畸变矫正算法是可行有效的。
The principle and the rectifying method of strap-down line scanning image distortion are introdued. Compared with platform line scanner, strap-down line scanner has many virtues. But the image distortion caused by aircraft attitude angle disturbance movement can affect target identification. The generation principle of image distortion for strap-down line scanning is analyzed, and the inverted mathematic model is established to rectify image distortion. An algorithm is proposed to rectify the line scanning distorted image and a rectifying software is compiled in Visual C++. The simulation results show that the strap-down line scanning image distortion rectifying algorithm is effective and feasible.
