摘要
红外探测器受材料和工艺限制存在盲元,降低了红外成像系统的图像质量,影响目标检测系统的检测概率和虚警率。有效、实时检测盲元并进行补偿至关重要。本文根据盲元在图像中与周围点的奇异性,利用图像目标检测的方法进行盲元检测;同时利用盲元的时间特性,将盲元与图像中的点目标区分开;最终实现高检测率,低虚检率的有效盲元检测算法。
The infrared detector has blind element because of the limitation of material and technology,it decreases the image quality of infrared thermal imaging system and influences the inspective rate and false alarm rate of target inspection system.Therefore,it is very important to conduct real-time and effective inspection for the blind element and make corresponding compensation.This article according to the particularity between the blind element in the images and surrounding points,adopts image target inspection method to inspect the blind element.Meanwhile,according to the time character of the blind element,separate the blind element from the point target area in the image.The purpose is to realize effective blind element inspection algorithm.
