基于航测方式获取地貌信息的探讨

Discussion on the Geomorphological Information Acquisition Based on Aerial Photogrammetry

利用JX4数字摄影测量工作站的影像匹配技术进行森林覆盖区域的DEM及曲线的生产。利用JX4的影像匹配及特征线解决复杂地理条件下的DEM及曲线的生产。利用DEM数据自动加注高程注记。

This paper discussed the production of DEM and curves for the area covered with forest using the image matching technology of JX4 digital photogrammetric workstation. It produced DEM and curves under complex geographic condition using the image matching and feature line extraction of JX4. It also realized the automatic annotation of elevation using DEM data.
