一种探雷声纳图像分割方法及应用

摘要

提出一种适用于探雷声纳图像的疑似水雷目标扫描分割方法.该方法以图像区域生长法为基础,根据探雷声纳的成像原理及水雷目标的图像特性,对区域生长法中的参数做了特别设定,分搜索和定位两步对图像中疑似目标进行扫描分割,讨论了搜索和定位两种扫描窗口的尺寸及扫描方法.将该方法应用于实际探雷声纳图像,可得到符合预定信混比要求的疑似目标区域,为基于探雷声纳图像的水雷自动判别奠定了基础.%An image segmentation method for mine detecting sonar images is proposed in this paper, which is based on the (SRG) seeded region growing segmentation method of normal image. This method has revised the parameter of SRG method relying on the imaging principle of mine detecting sonar and the properties of actual targets, discusses the sizes of two searching windows together with their searching process. Using this new method for actual sonar images, we achieves some suspected targets' region of predetermined SRR(signal-to-reverberation ratio). This method generates a solid foundation for automatic mine detection.
