Abstract

The invention provides an air-based platform image-based rail foreign body monitoring method and device. The method comprises steps: a to-be-processed image is acquired, wherein the to-be-processed image is a rail image photographed by a low-altitude unmanned aerial vehicle; the effective gradient information of the to-be-processed image is acquired; according to the type of the effective gradientinformation, the effective gradient information is subjected to coding processing to obtain a first feature; according to the hue, saturation and transparency HSV color model of the to-be-processed image, a second feature is obtained; and according to the first feature and the second feature, whether a foreign body exists in the rail in the to-be-processed image can be judged. According to the air-based platform image-based rail foreign body monitoring method and device provided in the invention, the effective gradient information and the color information of the image are combined to judge whether a foreign body exists in the rail, and the rail foreign body monitoring efficiency is improved.

Description

technical field [0001] The invention relates to aerial monitoring technology, in particular to a method and device for monitoring foreign objects on rails based on images of space-based platforms. Background technique [0002] Rail transit is the main way for the country's passenger and freight transportation, and it has very important strategic significance. Among them, railway transportation plays a particularly important role. Due to the large population of our country, the large-traffic railway traffic requires more rigorous security inspections to ensure the safety of passengers. [0003] In the prior art, with the wide application of low-altitude drones in the field of inspection and surveillance, more and more air-based platforms using low-altitude drones are used for inspections along railway lines to save manpower and material costs. The railway track maintenance personnel monitor the condition of the railway through the pictures of the railway track sent back by ...
