摘要：针对跑道信息在机场目标识别算法中的重要性,分析了巡航子母弹在实施跑道封锁时对跑道端点信息的需求,给出了机场红外图像的灰度约束先验知识,针对传统霍夫变换无法获取直线端点信息的特点,提出了一种新的基于灰度特征约束的HT附加策略识别算法,对低对比度的红外图像进行了识别,仿真计算结果表明,可以较为有效地获得准确的跑道中点和端点信息。
Aiming for the key roles of the runway for airfield recognition,a new algorithm with gray constraint accessional strategy is presented.The information of runway endpoints that the cruise missile needs to destroy the airfield is discussed and the prior knowledge of the gray constraint for the airfield targets in infrared image is given. Compared with the traditional Hough Transform algorithm,the new algorithm here is more effective to obtain the information of the midpoint and the endpoints of the runway.The result of experiments demonstrate effectiveness of this method.
