红外长线列探测器位置错位校正方法

红外长线列探测器在扫描成像系统中正得到越来越多的广泛应用,相应的遥感图像预处理工作的重要性也日渐突出,红外长线列探测器位置校正是遥感图像预处理的重要组成部分,对其方法的研究有着重要的实用价值.针对多元红外长线列探测器模块内像元错位和模块闻位置错位,提出并用FPGA实现了一种红外长线列探测器位置错位实时校正方法.实验结果表明该方法效果良好,可以有效的消除图像错位畸变,提高图像质量.

Dislocation Correction of Long Linear Infrared Detectors

As the Long Linear Infrared Sensors are now widely used in the scanning-systems,the preprocessing of the corresponding remote sensing images is becoming more and more important.Dislocation Correction of Long Infrared Linear Sensor is an important part of image preprocessing and the research of the used methods has great application value.In this paper,Methods of Dislocation Correction of multi-element Detector between pixels and that among modules ate put forward and implemented in FPGA.The result shows the methods put up in the paper can effectively eliminate the dislocation of images and can greatly improve the location-distorted image quality.
