Abstract: ABSTRACT: How to transform the abstract into a traditional method of monitoring and controlling the construction site of tension tension tension tension lines, such as using supervision personnel to squat, telescope observation, and online video placement, which consumes a lot of manpower and is limited in control. There are shortcomings in detail control, and the control of key construction steps is weak. This article cites drones to control on-site construction operations, from local to overall, and from point to line, From line to surface, the entire work surface is subject to three-dimensional control, with real-time supervision of the key points and key steps of traditional control, reducing personnel costs and effectively improving control efficiency.
