地图模式信息的获取

Obtaining Map Pattern Information

着重讨论了图像扫描仪和地图模式信息的获取,并针对胶片地图扫描受光衍射的影响,提出了一种新的动态阈值算法,修改扫描程序.最后,对地图模式信息获取子系统加以讨论.

Image scanner and obtaining map pattern information are expounded in thispaper. According to the effect of light diffraction in scanned map film, a new trendthreshold algorithming is proposed to improve scanned program. And a subsrrtem ofobtaining map pattern information is discussed at last.
