Abstract

The invention relates to a method and system for monitoring railway snow depth and wind and snow movement track based on image processing, which belongs to the field of image processing technology, and is characterized in that it at least includes: S1. Set up signage poles in the area; S2, collect digital image data of the signpost area; S3, extract the signpost images through image enhancement algorithm and image recognition algorithm in turn; S4, calculate the identification length of the signpost through the signpost images; The snow depth value is obtained by calculating the initial length and the identified length; S5, calculating the snow migration trajectory through the weather forecast data and the snow depth change. By adopting the above technical solution, the present invention utilizes the image processing technology to quickly and accurately monitor the snow accumulation depth and the movement track of wind and snow along the railway.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and system for monitoring railway snow depth and wind and snow movement trajectory based on image processing. Background technique [0002] As we all know, snow cover has always been one of the important hazards faced by railways in high latitudes. When snowfall and snowpack are accompanied by strong winds, large-scale migration of snowpack is more harmful. Therefore, timely and accurate acquisition of snow depth and snow migration information along the railway line under the action of strong wind is the premise to ensure the safety of railway construction and operation, and to evaluate snow protection measures. Under the environment of strong wind and heavy snowfall, traditional manual measurement faces difficulties in personnel transportation and operation, high risk factor, and low efficiency. Pressure components to monitor snow depth are compli...
