| 摘 要： | 该文提供一种地形图扫描文件的纠正方法,可使变形的位图获得纠正。地形图扫描文件的变形是图纸的收缩变形和扫描过程中变形的总和。该文采用的变形纠正数学模型与航测中改正像点坐标系统误差的数学模型相同。实践证明该方法可行。

| Abstract: | The paper provides a kind of correcting method of scanned files in topographic map,it can correct deformed bitmap.The deformation of scanned files in topographic map consists of two parts: shrinkage deformation of drawing and deformation in scanning.The deformation correcting mathematical model adopted in the paper is the same as the mathematical model of correcting image point coordinates system errors in aerial surveying.The practice proves the method is feasible. |
