摘要
采用本文坐标转换方法,将所截矩形图片四个顶点定位变形,分析变形处理后图片的偏差,发现其偏差与图片区域东西向长度及区域纬度关系较大,并计算出偏差值,分析偏差及精度关系,对工程人员有一定的参考意义。
Using coordinate transformation method, this paper cut rectangular images by four vertices localization deforma- tion, analyzed deviation of images after deformation processing, and found that the deviation of images between regional east -west length and latitude is larger, and calculated the deviation value, analyzed relationship between deviation and preci- sion, and the paper has certain reference significance for engineering personnel.
