| 摘 要： | 利用Erdas imagine 8．6软件，结合DGPS野外采集的地面控制点，采用多项式变换法，对蛟河林业实验区管理局所辖区域的SPOT5图像进行几何精校正。结果表明：当多项式次数取3次，控制点个数此为0．06～0．09个／km^2时，校正精度最高。校正后误差为0．7410个像元，即1．8525m。

| Abstract: | Using Erdas imagine 8.6 software Combined with collected ground control point by DGPS in field acquisition,and adopting the method of polynomial transform,the SPOT5 image of experiment area in Jiaohe forestry administration bureau was calibrated The results showed that the highest correction accuracy was gained when the degree of polynomial was three times and GCP density was 0.06-0.09 GCP/km2.the calibration error was 0.741 0 pixel,that is,1.852 5 m. |
