| 摘 要： | 本文针对多个条带WorldView卫星图像,研究了基于有理函数模型的附加参数区域网平差方法,对高分辨率卫星图像定位精度进行了详细分析。青海地区WorldView卫星图像试验结果表明:无地面控制点时,多条带整体区域网定位结果优于各个条带单独平差结果,区域网平差方法结果优于直接前方交会方法;有地面控制点时,多条带区域网平差结果与各个条带单独平差结果相当,且沿路线不大于10km布设一个地面控制点,其精度可满足1∶2000比例尺加密精度要求,可用于公路初步设计。

| Abstract: | For multi-strip WorldView satellite imagery,the paper studied the Rational Function Model based bundle adjustment method,and the geolocation accuracy was thoroughly analyzed.The test was made on WorldView imagery in the Qinghai province,and the results showed that:under no control point condition,the result of overall adjustment of multi-strip WorldView imagery is better than that of one strip separate adjustment,but they are both superior to the result of forward intersection;when there are control points,the results of overall adjustment and separate adjustment are similar,and which could meet the requirements of 1∶2000 scale topographic map when laying out control points with distance less than 10km along the route and could be used for the road preliminary design stage. |
