无人机航测系统实测1∶500地形图的精度探讨

Precision Discussion of UAV Aerial Survey Actual Measurement of 1 ∶500 Topographic Map

无人机航摄系统作为传统航空摄影测量手段的有力补充,在小区域大比例尺地形测绘领域发挥了积极有效的作用。本文以哈尔滨市呼兰测区为例,采用无人机平台获取航片,探讨基于无人机无控制点制作1∶500比例尺测图的可行性。

UAV aerial photography system,as a powerful supplement to traditional aerial photogrammetry,plays an active and effective role in small area and large scale topographic mapping.Taking Hulan of Harbin as an example and using UAV platform to obtain aerial film,the feasibility of making 1∶500 scale mapping based on UAV without ground control points was discussed.
