| 摘 要： | 为了分析仿射变换模型对煤矿矿图手工数字化位置数据系统误差的控制能力，首先导出了ＡＴ模型参数误差估计的基本公式，然后进一步导出了ＡＴ模型输入，输出数据间误差传播的通式。基于此，通过理论推证和为数值实验分析得出了四角检验点为最佳布设方案的结论。

| Abstract: | To study the ability of Affine Transformation (AT) model in controlling the systematic errors, a basic formula for estimating the AT model parameter errors is derived. And a general formula is further induced to find out the propagation errors in inputting and outputting data by AT model. The optimal design of four control points in registration of a mining map was found based on the formula and checked by theoretical deduction and numerical simulation. |
