基于POS的多视倾斜影像展绘与筛选方法

A Plotting and Selecting Method of Multiview Oblique Images Based on POS

以机载POS数据为基础,利用ArcEngine进行二次开发,实现多视倾斜影像拍摄范围在谷歌地球上的展绘,以及完成对海量多视倾斜影像数据的筛选工作。该方法首先采用测区平均高程和POS对影像直接定位;然后,利用DEM数据迭代求解提高精度;最后,实现数据的展绘与筛选。实验证明,该方法能较好地完成对多视倾斜影像的展绘与筛选工作。

Based on the airborne POS data and using Ar- cEngine to do the secondary development, we plot the shoot- ing range of muhiview oblique images on Google Earth , and complete the selection of large amount of multiview oblique images. Firstly, the average elevation of the survey area and POS data are used to position images directly. Secondly, DEM data are used to improve the accuracy by iterative sol- ver. Finally, we complete the show and selection of the da- ta. Experimental results show that the method can accom- plish the jobs of plotting and selecting of muhiview oblique images better.
