| 摘 要： | 在采用多项式模型进行遥感影像的几何精校正中,控制点的选取对校正精度有重要影响。本文通过实例计算,分析比较控制点的数量、分布对校正结果的影响,分析结果表明:适当增加控制点的数量会提高校正精度,但控制点数量并非越多越好;选择均匀分布的控制点有利于提高几何校正的精度。

| Abstract: | The selection of ground control points plays an important influence on the accuracy in geometric correction of remote sensing image in the polynomial model. Through calculation of examples, this paper analyses and compares the influence of the number and the distribution of ground control points. Analysis results show that： the right to increase the number of ground control points will improve the accuracy of correction, but the number of control points is not the more the better; selection of control points uniformly distributed is helpful to improve the geometric correction accuracy. |
