扫描地图的定向与纠正

ORIENTATION AND RECTIFICATION OF SCANNED MAPS

介绍了通过识别地图编号得到地图位置信息 ,进而利用公里格网点对扫描地图进行定向与纠正的过程。

A process for scanned map orientation and rectification according to map codes and mile-grid crosses has been described in this article. So we can orient and rectify scanned map with these theoretical and existent coordinates. As an emphasis, the authors describe the algorithm of mile-grid-matching based on LMSE, and map code recognition as well.
