摘要
为解决海天线附近红外弱点目标的检测问题,提出了一种新的弱点目标检测方法。该方法通过多向梯度检测来实现对弱点目标的检测,具有运算结构简单,计算量小的特点。仿真实验结果表明,该方法可有效剔除海天线、云层以及海浪等自然背景的边缘,大大提高了复杂背景下弱点目标的检测性能,并可满足舰载红外警戒系统中弱点目标检测的实时处理要求。
A new algorithm based on multi-orientation grads detection is presented to solve the problem of target detection of weak infrared point targets near the sea-horizon. The algorithm has the virtue of simple operation structure and speedy calculation. The experimental results show that the sea-horizon and the brim of cloud and ocean wave can be eliminated very well and the performance is very well to detect weak point targets under complicated background, and it can fulfill the time demand of target detection in the shipboard infrared search and track system.
