摘　　要：针对线列红外探测器扫描成像特点,提出了一种基于平台直方图统计的红外图像增强算法。仿真结果表明,该算法能够校正扫描型热像仪由盲、闪元引起的黑白道,提高图像的对比度,修正全局灰度等级,锐化图像中的边缘细节,对扫描成像系统的红外图像具有较好的增强效果。Aiming at scan imaging characteristics of the line array infrared detector,an infrared image enhancement al-gorithm based on histogram statistics platform is proposed.The simulation results show that,the algorithm can correct black and white lines caused by blind and flash pixels of scanning thermal imager.It can also improve the image con-trast,revise global grayscale,and sharpen edge details of the images.This algorithm has good enhancement effect for infrared image of scanning imaging system.
