5G基站精细化建模的倾斜摄影数据采集方式比较

针对5G基站智慧巡检问题,以昆明市呈贡区某5G基站为例,采取不同航线规划,以倾斜摄影技术采集5G基站影像数据,构建5G基站三维模型,对3种航线规划获取的数据进行几何精度分析,并进行视觉纹理效果评价。实践证明,井字飞行法、五向飞行法及贴面环绕飞行法均满足三维地理信息模型数据产品规范中的成图比例尺1∶500中平面精度0.3 m、高程精度0.5 m的要求,但从视觉纹理效果而言,井字飞行法与五向飞行法均存在立面缺失、构件粘连的情况,贴面环绕飞行法相对能够较为完整地反应5G基站立面数据,适宜用于采集5G基站影像数据。

Aiming at the problem of 5G base station wisdom inspection,a 5G base station in Chenggong District of Kunming City is taken as an example,different types of route planning are adopted,5G base station image data is collected by tilt photography technology,5G base station 3D model is constructed,geometric accuracy analysis of data obtained from three route planning is conducted,and visual texture effect evaluation is carried out.It is proved that the tic-tac-toe,five-way flight and veneer surround flight methods meet the requirements of 0.3 m plan imetric accuracy and 0.5 m elevation accuracy in the scale of 1∶500 in the 3D geographic information model data product specification,but in terms of visual texture effect,the tic-tac-toe flight method and five-way flight method have missing elevations and adhering components,and the veneer surround flight method can relatively completely reflect elevation data from the 5G base station,and thereby is suitable for collecting 5G base station image data.
