本文详细地介绍了一种基于PC机的立体图象显示和观察装置。该装置利用TVGA-8900显示卡的帧同步信号,通过特殊的软件交替切换左右两幅图象并控制液晶(LCD)开关眼镜在PC机监视器上实现立体图象显示和观察的。它具有分辨率高,实时性好,操作简单等特点,并能根据观察者的需要随意改变物体的前后位置。该装置在医学图象诊断和工业无损探伤等领域具有较大的应用价值。
This article describes in detail a PC-based stereo image display and observation device. The device uses the TVGA-8900 graphics card frame synchronization signal, through the special software to alternately switch the left and right two images and control the liquid crystal (LCD) switch glasses in the PC monitor to achieve three-dimensional image display and observation. It has high resolution, real-time, easy to operate and so on, and according to the needs of observers to change the object before and after the position. The device has great application value in the fields of medical image diagnosis and industrial non-destructive testing.
