【摘要】 可视化就是运用计算机图形学和图像处理技术,将科学计算过程中产生的数据和计算结果转换为图形或图像在屏幕上显示出来,并进行交互处理的理论、方法和技术。在水声学研究中,我们用声波探测水底的世界,为了让我们所得到的抽象数据变为我们能够轻易看懂的图形图像,我们为之设计了很多基于可视化基础上的显控平台。本文是在高分辨率成像声纳系统和回波测深仪的两个控制平台的基础上对声纳图像数据的高速显示技术的研究。对现代的声纳图像显控平台来说,图像是否能够实时快速显示是检验该平台是否优越的重要标志。而对本文所研究的两个平台来说,在近距离扫描和测深的情况下,原有的软件并不符合要求,因此,本文的研究显得尤为重要。首先,我们改变了高分辨率成像声纳系统的绘图和显示方式,采用高效的DirectX软件包和多线程的引入使得程序执行效率更高,显示速度更快。其次,我们基于某些具体要求对原有的双频回波测深仪进行改动,使它变为基于网络通信传输的高频测深显控系统。该过程是为了实现网口模式下的测深快速显示过程,其中我们不但要去掉所有功能模块的高频部分,而且需要对原有的数据结构和通信方式进行改变。文中所有的程序编写都是使用C和C++语言,在WindowsXP平台下利用VC++ 6.0进行编译和调试的。更多还原

【Abstract】 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.更多还原
