摘要
随着数字化电站建设的发展,老水电站的数字化也面临着挑战,如何在图纸资料不全的情况下实现老水电站数字化是个难题。采用无人机倾斜摄影测量与自动化建模技术完成新安江水电站枢纽数字化建设工作,建立新安江水电站包含大坝、开关站等在内的枢纽精确模型。在无人机采集数据过程中,针对开关站和大坝区域高压出线密布的情况,采取航摄分区和近景摄影的办法分区域获取开关站和大坝等的影像数据,分区域获得的影像数据导入自动建模软件Smart3DCapture进行建模,建模过程中采用Delaunay三角网进行重构完成实景数字化自动建模。采用该方法建立的新安江水电站枢纽数字化模型精度高,可以应用于老水电站大场景数字化建模。
With the development of digital power station construction,the digitalization of the old hydropower station is also facing challenges.How to realize the digitalization of the old hydropower station under the condition of incomplete drawings and data is a difficult problem.In this paper,tilt photography and automatic modeling technology are used to complete the digital construction of Xin'anjiang hydropower station,and the precise model of Xin'anjiang hydropower station including dam and switch station is established.In the process of UAV data acquisition,aiming at the situation that the high-voltage outgoing lines are densely distributed in the switch station and dam area,the method of aerial photographing and close photographing is adopted to obtain the image data of switch station and dam in different regions,and the image data obtained in different regions are imported into the automatic modeling software smart3dcapture for modeling.In the process of modeling,Delaunay triangulation is used to reconstruct the real scene digital modeling.The digital model of Xin'anjiang hydropower station based on this method has high precision.It can provide a reference for the old hydropower station large scene digital modeling.
