摘    要:扇扫声纳在搜寻目标,躲避障碍物,跟踪动态目标,水下检视等方面有着广泛的用途。针对影像噪声大,实现动态目标的自动跟踪有较大难度的问题,分析了扇扫声纳影像中动态目标和静态目标的特点,利用目标在序列影像中的变化完成动态目标的分离,在此基础上,使用卡尔曼滤波方法实现动态目标的跟踪,最后结合实际数据进行了分析,表明算法的有效性。

关 键 词:扇扫声纳  动态目标  光流  卡尔曼滤波  跟踪

Abstract:The sector scan sonar plays an important role in searching static ohjects, avoiding obstacles, tracking dynamic objects, inspecting underwater environment, etc. However, because of large noise in the sonar image it is difficult to automatically track dynamic objects. In this paper, we analyzed the characteristics of dynamic and static objects, realized the separation of the dynamic objects from sonar image by means of the changes of objects in sequent imagery. Then, Kalman filter technology was used to realize the track of dynamic objects. The method was verified by the real data.
Keywords:sector scan sonar  dynamic obj ect  optical flow  Kalman filter  tracking
