Low-visibility weather phenomenon monitoring method based on image recognition technology

Abstract

The invention relates to the technical field of visibility weather phenomenon monitoring, in particular to a low-visibility weather phenomenon monitoring method based on an image recognition technology. A monitoring device used in the method comprises a loop, an imaging module, a visibility sensor, a weather phenomenon receiver and a controller. The section of the loop is I-shaped, and the bottom of the loop is fixedly connected with electric push rods. The electric push rods are uniformly distributed at the bottom of the loop, and the end parts of the electric push rods are fixedly connected with supporting legs. The top of the annular channel is in sliding connection with a sliding plate. The lower end of the sliding plate is rotationally connected with two rollers. According to the monitoring device used in the low-visibility weather phenomenon monitoring method based on the image recognition technology, the electric push rods drive a slide way to move up and down, a motor drives a slide plate to slide along the slide way, so that the monitoring range of the imaging module and the visibility sensor on the surrounding area is expanded, and the accuracy of the visibility is improved.

Problems solved by technology

[0002] Visibility and weather phenomena are two important meteorological observation elements, which provide an important basis for weather forecast, meteorological information, climate analysis, scientific research and atmospheric monitoring; the observation of visibility has transitioned from manual observation methods with low accuracy and poor objectivity to automation Measurement, while obtaining the measurement data, an intuitive on-site visibility image with a single direction and a fixed angle is added; due to the lack of existing technology, the on-site image with a single direction and a fixed angle cannot fully reflect the directional distribution and change of visibility in an area, especially in the Areas with complex and changeable topography, concentrated pollution sources, and fog movement on the main road network; at the same time, the monitoring situation of a single visibility sensor cannot accurately reflect the visibility of the area, resulting in monitoring errors in the area

[0003] In the prior art, there have also been some technical solutions for low-visibility weather phenomenon monitoring methods based on image recognition technology. For example, a Chinese patent with application number CN201220685526.4 discloses a visibility weather phenomenon monitoring with multi-directional panoramic shooting function. instrument, which includes an imaging device installed on the top of the column, a weather phenomenon receiver and a visibility sensor are installed on the column, a data acquisition instrument is installed in the cabinet, and the data acquisition instrument is electrically connected to the imaging device, the weather phenomenon receiver and the visibility sensor respectively; The camera installed with an angle adjustment mechanism makes up for the lack of single-direction fixed-angle shooting, and gets rid of the requirements for monitoring stations. It can be installed in open areas, residential areas and other monitoring areas where it is inconvenient to set up stations, which can reduce costs and reduce maintenance. It is easy to monitor. In areas where the terrain is complex and changeable, pollution sources are concentrated, and cloud fog is moving on the main road network, in the case of rapid changes in visibility and uneven regional distribution, the changes in visibility conditions in the surrounding environment can be observed by relying on the captured pictures. The difference in distribution can subdivide the atmospheric visibility changes caused by weather phenomena and haze pollution factors; however, the visibility of a single place measured by this technical scheme cannot accurately reflect the visibility of this area, which in turn causes the limitations of this scheme
