摘　　要：设计并实现一种相控阵三维声纳图像的离线数据处理系统,并进行可视化建模。系统中精确配准采用最近点迭代配准,结合外围点消除法,通过拟牛顿进行最优化。拼接融合及多帧再重建采用多级分辨率,同时支持低精度的快速显示和高精度的精细显示。测试结果证明,该系统能较好地实现相控阵三维摄像声纳图像的处理及可视化。In this paper,an off-line processing and visualization system of 3D phased array sonar data is designed.The system consists of modules of sonar data parsing,single-frame reconstruction,accurate registration,mosaicing and multi-frame reconstruction.The accurate registration module which includes Iterated Closest Point（ICP） algorithm with robust outlier rejection and Quasi-newton optimization,improves the precision of registration.The mosaicing and multi-frame reconstruction module reconstruct a range of frames by multilevel resolutions,which supports rapid display at low resolutions and also precise display for details at high resolutions.Test results show that this system can successfully complete the processing and visualization of phased array sonar data.
