The Study For High-speed Display Technology On The Sonar Image Data

We can convert data and results which get by scientific computing to graphic or image, make the graphics and image displayed on the screen and dealed with interactive disposal by using computer graphics and image processing technology . Visualization is a theory,way and technology like this. In the study of underwater acoustic,we use sound waves to detect underwater world. In order to change abstract data into a graphic or image we can easily understand, we design many display and control systems based on visualization.This paper studied the high-speed display technology on the sonar image data, which based on the two control platform:high-resolution imaging sonar system and echo sounder platform. According to the modern sonar image display and control platform, real-time image display is an important indicator superior for one platform's examination. For those two platform in my paper, the intrinsic software can't accord the request when it's under the close quarters and sound instance. Firstly, the mapping and display style in the high-resolution imaging sonar system has been changed. Using DirectX package and multithreading make program efficiency more efficient and make display speed faster. Secondly, we make changes on original software of dual-frequency echo depth sounder based on some requirements. It turned high-frequency sounding display control system based on network communication transmission. We not only remove high-frequency part in all functional modules, but also make changes on the original data structure and communication style.All programming of this paper are in the WindowsXP platform, using C and C++, and using VC + + 6.0 to compile and debug.
