Based on expatiation of the theory on visualization , technical measure , the theory of real terrain and the modeling techniques on real - time dynamic display of 3d terrain , author has made uses of opengl to realize terrain visualization based on dem 笔者在阐述了可视化的原理、技术手段、地形的真实感图形绘制原理、三维地形的实时动态显示的建模技术等理论的基础上,利用开放式的高性能图形和交互式视景处理标准的opengl技术,实现基于dem的地形可视化。
M - mode is a kind of dynamic display mode . it also uses the brightness to represent the strength of the ultrasonic returns , but the independent variable in the display is time . returns from different scanned depths are revealed along the time axis to show the movement of different layers of the scanned organs M型是一种运动显示方式,它也是以亮度的强弱来表示回声信号强弱,但将声束路径上不同深度的回波图象沿时间轴慢慢展开,以表示界面的运动轨迹。
At the same time the author makes a deep research into the serial communication of the controlling signals of the sonar , the dynamic displaying of the image as well as the image post - processing and classification for the sake of sonar intelligentizing and the computer aided classification 本文以投入正样机研制的猎雷声呐为背景,在着力解决工程实际问题的同时,对声呐设备中控制信号的串行通信、声纳图像的动态显示以及后置图像处理与识别做了较为深入的研究。
The simulation system includes the optics , chopper control , driving signal design , image data acquisition based on vi technology and image processing including image difference , non - uniformity correction ( nuc ) , image intensification and dynamic display , etc . according to the corresponding theories , the author designed all these software modules . the research on the pyroelectric imaging technology through this experiment is of great importance to practical thermal imaging system in the future 根据热释电焦平面成像原理,用sspa器件在可见光条件下设计了基于虚拟仪器技术的热释电凝视焦平面成像模拟系统,包括光学系统、斩波控制、驱动信号设计、基于虚拟仪器技术的图像数据采集和相关的图像处理技术,如图像差< wp = 5 >分、非均匀性校正、图像增强和动态显示等。
