Abstract

The invention discloses a method and a system for an unmanned aerial vehicle holder to automatically track a railway area, and belongs to the technical field of aviation monitoring. The method comprises: a rail part is detected based on a collected image, the center-of-gravity coordinate of a rail in the image is calculated, the deviation vector of the center of gravity of a rail area and the center of an image picture and the respective angles of the two rails are calculated and input into a holder servo control module, so that the railway is kept in the center of the image in the unmanned aerial vehicle inspection process, and the effect is remarkable. The method can be used for automatic control of the camera holder for unmanned aerial vehicle railway inspection, improves the information quality of collected rail data, has the advantages of small calculated amount, short response time, good control effect and the like, and has great significance for subsequent rail foreign matter detection and daily analysis of inspection railways.

Description

technical field [0001] The invention belongs to the technical field of aerial surveillance, and relates to a method and system for a railway inspection-oriented unmanned aerial vehicle platform to automatically track a railway area. Background technique [0002] Under the situation of rapid development of my country's railway construction, the process of railway network construction has been significantly accelerated. The traditional line patrol inspection is that the staff use ordinary instruments or naked eyes to inspect the facilities, record the patrol situation in the form of paper media, and then manually enter it into the computer. Therefore, the quality of inspection results is affected by human factors, and the life safety of line inspectors will be endangered in dangerous areas, and the amount of manually entered data is large; at the same time, it is impossible to effectively manage whether the inspection personnel are in place, and the inspection quality cannot ...
