摘要
将实景三维建模技术应用于消落区景观打造中,动态监测水库消落区,为景观规划、库岸治理及生态环境管理提供全面且精准的数据支持.以肇庆市FLX-A23消落区为例,探索如何利用这一技术为行业带来实质性的效益.利用无人机搭载高清航测镜头对消落区所在区域进行倾斜摄影测量,利用点云投影软件Pix 4D Mapper对消落区进行了实景三维建模.对模型数学精度的验证结果表明:模型满足消落区梯级景观打造所需的测绘数据精度要求,可为消落区库岸治理提供可靠的依据.
Abstract
The real-time 3D modeling technology applied in the construction of the landscape of the reservoir's subsidence area provides comprehensive and accurate data support for landscape planning,reservoir bank management,and ecological environment management through dynamic monitoring of the reservoir's subsidence area.The FLX-A23 subsidence area in Zhaoqing City is taken as an example to explore how to use this technology to bring substantial benefits to the industry.Using a drone equipped with a high definition aerial survey lens,oblique photogrammetry was carried out in the area where the subsidence area is located.The point cloud projection software Pix 4D Mapper was used to create a realistic 3D model of the subsidence area.The verification results for the mathematical accuracy of the model showed that it meets the accuracy requirements of surveying data required for the construction of the cascade landscape in the subsidence area,and can provide a reliable basis for the management of the reservoir bank in the subsidence area.
