摘要
本文采用无人机飞马D-2000为飞行平台,搭载飞马D-OP4000相机,获取日喀则市主城区共计105.6 km^(2)航摄影像并重建三维模型,基于三维模型与往期数据修补日喀则市城区1∶500地形图;开展地下管线探测及普查工作,完成探测日喀则城区700 km地下管网及100 km地下排水管网,分析排水管网缺陷的主要因素;基于三维模型与管网数据,搭建管线平台系统,实现了地下空间安全运行的宏观监测、地下空间综合管线二三维数据一体化、排水管网在线监测以及道路窨井盖安全监测。
This article utilizes the Feima D-2000 Unmanned Aerial Vehicle(UAV)as the flight platform,equipped with the Feima D-OP4000 camera,to capture aerial images covering a total area of 105.6 km^(2)in the main urban area of Shigatse City.Subsequently,a three-dimensional model is reconstructed based on these images.Using the three-dimensional model and existing data,a 1∶500 topographic map of the urban area of Shigatse City is created.Furthermore,underground pipeline detection and survey work is conducted,covering a total length of 700 km for the underground pipeline network and 100 km for the underground drainage pipeline network in the urban area of Shigatse City.The primary factors causing defects in the drainage pipeline network are analyzed.Based on the three-dimensional model and pipeline data,a pipeline platform system is established,enabling macro-monitoring of underground space for safe operation,integration of two-dimensional and three-dimensional data of comprehensive underground space pipelines,online monitoring of the drainage pipeline network,and safety monitoring of road manhole covers.
