Abstract: A software system, which can realtimely complete the 3D modeling of submarine sonar data and display is developed with VTK. The modeling process includes the realtime construction of the single frame and the realtime registration and mosaicing of a range of frames. The mosaicing module of a range of frames resolves the problem that as the number of frames increases, the mosaicing efficiency reduces. Test results show that this system can successfully complete the realtime visualization of sonar data and display it.

Key words: submarine sonar, threedimensional modeling, realtime processing, mosaicing

摘要： 设计并实现对海底声纳数据进行实时三维建模的系统，利用可视化工具包VTK实现建模结果显示功能。建模过程包括单帧数据实时建模、多帧数据实时配准与拼接，解决了数据不断增多时拼接速度变慢的问题。测试结果证明，该系统可以完成对声纳信号的实时可视化处理并显示结果。
