Abstract

The invention discloses a railway engineering detection method and system based on an unmanned aerial vehicle inspection video. The method includes: detecting the inspection video frame by frame based on a target detection algorithm and obtaining a plurality of target detection frames including target structures; The target tracking algorithm tracks each target detection frame and obtains the target trajectory of each target structure; determines the estimated coordinates of each target structure according to the frame data of each trajectory frame in each target trajectory; The design data of each target structure in the inspection video determines the positioning information of each target structure in the inspection video; among them, the inspection video is based on the video of the whole or part of the predetermined railway line shot by the drone, and the frame data includes unmanned The position data of the drone and the attitude data of the camera can be used to automatically and accurately detect the target structures on the railway line from the drone inspection video, thereby improving the efficiency of railway construction inspections.

Description

technical field [0001] The present application relates to the technical field of railway construction engineering monitoring, and more particularly, to a railway engineering detection method and system 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 railway mileage under construction and planned new construction, it has brought greater challenges to the inspection work of the entire high-speed railway construction site. [0003] Railway lines include a variety of structures, such as tunnels, bridges, piers, roadbeds, tracks, four electrical engineering (communication engineering, signal engineering, power engineering, electrification engineering), station yards, housing construction, etc. The construction of each structure is inspected, and the application of UAV aerial photography technology has improved the efficiency of l...
