| 摘 要： | 作者以计算机打印字符占纸面积为基本坐标单元建立统一的坐标系,对非监督分类后的MSS数字图象进行几何精纠正,并将其与相同比例尺的地形图进行对照检查,结果表明,纠正中误差仅为±47.5米,相对误差不到一个象元,能够满足中、小比例尺MSS专业制图的精度要求。

| Abstract: | The precise geometrical correction method to MSS digital image with the microcomputer was probed and discussed.The digital unsupervised classified image was geometrically corrected with the computer printed character as the primary coordinate grid unit to establishing uniform coordinate system.The results showed that the error mean squares is 47.54M only,and the relative error generally did not reach to one pixel by comparatively checking the corrected image with the topographic map at the same scale.Therefore the needs of the accuracies of the professional mapping at the middle-small scale can be met this method. |
