Abstract

The invention discloses a railway engineering detection method and system based on an unmanned aerial vehicle inspection video. The method comprises the following steps: performing frame-by-frame detection on the inspection video based on a target detection algorithm, and obtaining a plurality of target detection frames comprising target structures; tracking each target detection frame based on a target tracking algorithm and acquiring a target trajectory of each target structure; according to the frame data of each trajectory frame in each target trajectory, determining an estimated coordinate of each target structure; determining the positioning information of each target structure appearing in the inspection video according to each estimation coordinate and the design data of each target structure in the railway line design drawing; wherein the inspection video is a video obtained after the unmanned aerial vehicle shoots the whole or part of the predetermined railway line, and the frame data comprises the position data of the unmanned aerial vehicle and the attitude data of the camera, so that the target structure on the railway line can be automatically and accurately detected from the inspection video of the unmanned aerial vehicle, and the efficiency of railway construction inspection is improved.

Description

technical field [0001] The present application relates to the technical field of railway construction engineering monitoring, and more specifically, to a method and system for railway engineering inspection based on drone inspection video. Background technique [0002] Construction monitoring is an important part of railway construction management. In recent years, with the explosive growth of high-speed railways under construction and planned new mileage, it has brought greater challenges to the inspection work of high-speed railway construction sites. [0003] Railway lines include a variety of structures, such as tunnels, bridges, bridge piers, roadbeds, tracks, four electrical projects (communication engineering, signal engineering, power engineering, electrification engineering), stations, housing construction, etc. Conduct inspections on the construction of each structure, and the application of UAV aerial photography technology has improved the efficiency of line insp...
