摘要
基于对线路平面扫描图产生几何畸变的分析 ,提出了用 NE网格规整方法对大幅面线路平面图进行网格分割与几何畸变校正 ,并按照 NE网格进行图块的拼接 。
On the basis of the analysis of the geometry distortion of the scanned route brid's eye map images, this paper presents an algorithm for normalizing NE grid, which divides large size map images into small files in uniform size, reduces geometry distortion of these parts, and links them in order. Then the continual display of stripling birds eye maps is realized.
