Accumulated water monitoring and warning device for railway based on machine vision and method

Abstract

The invention is suitable for the field of accumulated water monitoring for railways, and provides an accumulated water monitoring and warning device for a railway based on machine vision and a method. The method comprises the steps that after a railway video is acquired through a camera, image extraction is conducted according to frames, image binarization processing is conducted, color spaces ofrailway images are converted into HSV converted color space models capable of being conveniently processed, and geometrical characteristics of the railway are obtained; a Canny edge detector is usedfor edge detection, clearer edges are extracted for the railway images, and an erosion and dilation technology is adopted for achieving image denoising and edge enhancement, so that geometrical characteristics of the images are enhanced; finally, Hough transformation is conducted, contrasted with preset standard railway images, whether or not accumulated water covers the railway is judged, and therefore accumulated water data is obtained. When it rains, the camera works to monitor water accumulation conditions of points in real time, the accumulated water data and Beidou positioning information are transmitted to a monitoring center though a data transmission device, and corresponding alarm reminding is conducted, so that water accumulation railway sections are treated in time.

Description

technical field [0001] The invention belongs to the technical field of railway water accumulation monitoring, and in particular relates to a machine vision-based railway water accumulation monitoring and alarming device and method. Background technique [0002] As we all know, the current machine vision technology has been widely used with the rise of artificial intelligence. Computers are mainly used to simulate human visual functions, extract information from images of objective things, process and understand them, and finally use them for actual detection. Measure and control. The biggest feature of machine vision technology is fast speed, large amount of information, and multiple functions. Therefore, this also provides a new idea for railway water monitoring. [0003] As we all know, railways, as the main economic artery of our country, play a very important role in economic and social development, so the safety issues along the railway lines are extremely important; ...
