摘要
以黄埔区某村旧改例,提出了面向"三旧"改造的基于无人机倾斜摄影技术获取大比例尺地形图的工作流程,并通过对点位、边长、高程和建筑物面积检查精度分析,验证了该技术的可行性,并为其他"三旧"改造项目提供了一定的参考。
In this article,taking a village in Huangpu District for example,we proposed a workflow for obtaining large-scale topographical maps based on UAV oblique photography technology for the renovation of"Three Olds".And through the inspection accuracy analysis of the point position,side length,elevation and building area,we verified the feasibility of the technology,and provided a certain reference for other"Three Olds"renovation projects.
