基于三维实景模型的水库无线视频监控系统

以前坪水库为例,水库建设期视频监控系统信号采用无线网桥传输,基于无人机航摄生成三维实景模型进行视频监控点及无线网桥布置设计。介绍了采用大疆无人机DJ1 PHANTOM4 PRO进行航飞倾斜摄影,采用ContextCapture3D生成三维实景模型的过程步骤,对基于三维实景模型优化监控点布设及视野和信道复核的方法进行了研究。实践表明,基于无人机三维实景模型的水库无线视频监控系统设计可靠,可为其他类似工程参考借鉴。

Wireless video reservoir monitoring system based on 3D real scene modeling

During the construction of the Qianping reservoir, a wireless signal bridge was designed and applied to signal transmission, and a video surveillance system, based on the unmanned aerial vehicle (UAV) photography, was developed to generate three-dimensional real-time models for the monitoring points. This paper presents a method of the aerial photographer's oblique photography using the Dajiang unmanned aerial vehicle DJ1 PHANTOM4 PRO and a procedure for generating 3D real scene models using Context Capture 3D. We describe a method for optimizing the layout of monitoring points, visual field, and channel rechecking based on the 3D real scene model. Application shows that the wireless video surveillance system is reliable and useful for monitoring reservoirs and other similar projects.
