| 摘 要： | 文章根据光束法区域网平差原理,利用ERDAS的OrthoBASE模块对2006年内蒙古磴口县乌兰布和沙漠拍摄的130张航空像片,共10条航带进行了GPS辅助空中三角测量,并对其进行了正射投影纠正,生成了1km2实验区比例尺为1∶1000影像图,影像图地面分辨率为0.1m,达到了相当高的精度。这也是我国林业部门第一次使用基于PPP精密单点定位导航的数码航摄系统生成的正射影像图。

| Abstract: | Base on the theory of bundle aerotriangulation,using OrthoBASE module of ERDAS software,130 digital airscapes consisted of 10 strips were orthorectified by GPS-supported Aerial Triangulation,which were taken in Wulanbuhe desert in Inner Mongolia in 2006.Then 1 km 2area images(1:1000 scale) were obtained,and image resolution was 0.1m.It was the first time that orthophoto image was generated by digital aerial photograph system based onby PPP(Precision Point Position) navigation in China forestry. |
