摘要
载体平台在行进间的振动会导致光电全景成像系统采集的图像发生几何畸变。为了校正图像,本文提出了一种基于惯导信息的图像校正算法,该算法首先采用基于惯导信息的图像坐标转换方案,得到了校正后图像与原图像坐标点的对应关系;然后通过基于边缘导向的插值法,确定了校正后图像中各像素点的灰度值。实验表明,该算法可以有效实现光电全景成像系统的图像几何校正,并抑制了图像的边缘模糊效应,提高了图像复原的效果。
Vibration of carrier platform during travel will lead to the presence of geometric distortion of the images, which were obtained by optical panoramic imaging system. An image correction algorithm based on Inertial Navigation Information was proposed, in order to correct the image. First of all, through the coordinate conversion scheme based on Inertial Navigation Information, we can get the corresponding relationship for coordinate points between the corrected image and the original image. Then, via the edge-directed interpolation method, we can determine the gray value of each pixel in the image after the correction. Experimental results show that the algorithm can effectively achieve the goal of image correction for optical panoramic imaging system, suppress the edge blur effect of images, and improve the effect of image restoration.
