摘要: 目前纸质的飞机系统图、原理图矢量化方法用基本的矢量图元按其位置来再现原始图,从而导致矢量后图中各符号整体信息丢失问题,该文提出的自动符号识别方法可有效地解决该问题,此外改进多级缓冲显示技术不但可有效地解决CBT中系统图、飞机原理图的快速显示,而且也保证图形可连续光滑滚动和消除放缩拖动时屏幕闪烁现象。

关键词: 纸质图, 矢量图, 符号识别, CBT

Abstract: The total auto symbol recognition disposition method proposed in this paper can deal with the problem which converts papery of aircraft theory graphics or system graphics into vectorgraphs which can lose some useful information. Furthermore, the display technique with multi-level buffer not only resolves the problem of high-speed for aircraft theory graphics or system graphics in CBT, but also ensures scrolling and zooming in/out smoothly and avoids the flashing phenomenon efficiently.
