A rail foreign matter detection method based on low-rank matrix factorization

Abstract

The invention discloses a rail foreign matter detection method based on low-rank matrix factorization, and belongs to the technical field of computer vision. The implementation process comprises the following steps: 1) carrying out straight line detection on an unmanned aerial vehicle aerial photography railway image, screening a straight line group, finding a rail edge straight line, and determining an area needing to be detected and processed; 2) extracting a pixel vector from the rail area and clustering the pixel vector, wherein the pixel vector can be divided into two subsets of sleepersand stones; 3) performing low-rank matrix decomposition on a matrix formed by the two subsets, and subtracting the obtained low-rank matrix with background information to obtain a foreground matrix; According to the method, the rail foreign matter is detected through an algorithm based on low-rank matrix decomposition, the foreign matter is quickly confirmed through images transmitted back in realtime through space-based monitoring, and the method can be used for the fields of railway safety monitoring and the like.

Description

technical field [0001] The invention belongs to the technical field of computer vision, relates to digital image processing technology and target detection technology, and specifically refers to a method for detecting foreign objects on rails based on low-rank matrix decomposition. Background technique [0002] Rail foreign object detection refers to the measures to check the rail area for foreign objects in order to ensure the safety of trains. According to the relevant regulations on the safe running of trains in our country, in the railway line safety protection zone and its adjacent areas, there must be no foreign objects that endanger the normal running of the train within the railway limits stipulated by the state, so as not to cause the driver to see the foreign objects at a relatively short distance. Braking treatment, but the braking is not timely, the braking distance is too long and the collision with foreign objects causes property damage and safety accidents. ...

Braking treatment, but the braking is not timely, the braking distance is too long and the collision with foreign objects causes property damage and safety accidents

[0003] When inspectors enter the railroad tracks without trains for maintenance, due to the nature of their work, they may leave their helmets, work wrenches and other items between the railroad tracks, or train passengers throw garbage and other foreign objects out of the window, causing train accidents.
