基于VirtuoZo平台的1∶10000地形图高程点快速生成技术

在利用VirtuoZo全数字摄影测量系统立体测图采集1∶10000高程点时,常常受到植被覆盖的山地及高山地等地形困扰,导致产生高程采集不准、点线矛盾、高程点分布不均、采集工作量大等问题。为解决这一难题,本文通过实际生产经验,利用DEM重构的方法自动获取高程点,可完全达到预期效果,大大提高了生产效率。

Rapid Generation Technology of 1:10000 Scale Topographic Map Elevation Points Based on VirtuoZo Platform

When stereo collecting 1∶10000 scale elevation points in VirtuoZo full digital photogrammetry system,we are often troubled by the problems,such as inaccurate elevation collection,contradiction between points and lines,uneven distribution of elevation points,heavy workload of collection and so on in vegetation covered lush mountains and high mountains.The DEM reconstruction method is used to automatically obtain elevation points,which achieves the expected effect and greatly improves the production efficiency.
