摘  要:
采用DGPS系统中的载波相位差分技术均匀地选取地面控制点,利用ERDAS IMAGINE9.1遥感影像处理软件,对天桥岭林业局太阳林场的SPOT5遥感影像进行了几何精校正。结果表明:采用3次多项式校正,相应面积控制点个数比在0.06~0.09(个.km-2)之间时校正精度最高,校正后误差为0.603个像元,即1.508 m。此方法不仅可以满足林业作业的精度要求,还可使外业工作量最小。

摘  要:
Using DGPS carrier phase differential technique evenly select the ground control points.Based on ERDAS IMAGINE9.1,the geometric precision correction of the remote sensing image of SPOT5 was processed in Taiyang forest farm of Tianqiaoling forestry bureau.The results showed that: by 3 times of polynomial correction,the appropriate number of control points area between 0.06 ~ 0.09(ind·km-2) appeared the highest correction precision,after correction the error was 0.603 ind pixel,namely 1.508 m.This method not only can content the accuracy requirement of forestry operation,still can make the minimum field work.
