Abstract: 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.
