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
