摘要
目标潜在区域的确定对于成像型反舰导弹的目标检测、目标识别具有重要意义。深入分析了海空背景及舰船目标的红外特性,提出了一种海空背景下确定弱小目标潜在区域的方法,首先利用梯度算子得到差分图像,然后基于边缘阈值策略二值化图像,最后利用二值化图像在竖直方向上的投影确定目标潜在区域。实验证明次种算法速度快、精度较高、能够有效地剔除部分干扰。
To get the region containing the dim targets is important for the target detection and target recognition of the imaging guided anti-ship missles. The characteristics of the sea-sky background and the ship target are analyzed in detail. A detection algorithm of the region containing dim target is presented, which is divided into three steps： 1）Getting the difference image by using directional operators; 2）Binarizing the difference image using the methods of edge threshold; 3）Getting the region containing the dim target by the projection of the binarized image on the vertical axis. The experimental results show that this algorithm costs less time, has higher precision and can restrain some interference effectively.
