基于反蛙人声纳的小目标检测算法

随着蛙人侵扰活动的日益频繁,在一些重要的部位如港口、码头、海岸洞库和锚泊水域中都安装了水下监控系统,在这些系统中,基于反蛙人声纳的小目标检测既是研究的重点也是难点之一。文章针对小目标检测问题进行了讨论,提出反蛙人声纳图像处理和小目标检测算法。由实践结果可以得出,此算法具有较高的小目标检测率,有效提高了水下监控系统的可靠性。

Algorithm for Detection of Small Target in Sonar Image Based on Anti-diver Sonar

Diver invading incidents happens more and more frequently.Underwater surveillance systems are installed in some important area,such as port,dock,seashore depository and anchorage.In these systems,the detection of small target based on anti-diver sonar is the researching emphasis and difficulty.The key issues in small target detection is discussed in this paper.An sonar image processing and detecting algorithm of anti-diver is proposed.Practising results are presented and indicate that this algorithm is of high detecting rate,which increases the reliability of the underwater surveillance systems.
