Device and method for detecting ice and snow thickness

Abstract

The invention discloses a device and method for detecting ice and snow thickness. The device comprises a ruler, a camera, a light-emitting diode (LED) floodlight and an image processing device, the ruler is used for being directly contacted with ice and snow and serves as a reference for ice and snow measurement, the LED floodlight is used for proving illumination for the ruler, the camera is used for collecting image data in a scope of the ruler, and the image processing device is used for obtaining the ice and snow thickness after processing the image data collected by the camera according to a dual threshold edge extractive image identification method. By means of the device for detecting ice and snow thickness, ice and snow quantitative measurement on public transit facilities such as airfield runways and expressways can be achieved, remote control of a computer can be achieved, multi-threshold real-time alarm on snow and ice disasters can be carried out, a provided intelligent supplementary lighting device can support all-weather monitoring, the dual threshold edge identification method removes background interference, and the device is high in reliability, simple in structure, visual in image and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of sensors and measurements, and more particularly relates to a device and method for detecting the thickness of ice and snow. Background technique [0002] Ice and snow cover reduce the surface friction of public transportation facilities such as airport runways and expressways, which can easily cause aircraft and automobiles to lose control, and cause huge safety hazards to the safety of people's lives and property. As a result, many researchers have made active attempts in the field of icing detection. The title of the invention is: Electrical Wire Ice Accumulation Measuring Device and Measurement Method. The patent application document with application number 201010300750.2 proposes a device and method for measuring electrical wire icing. This method uses image processing, but due to the lack of absolute scale As a reference, there is a certain error in the measured icing thickness. The name of the uti...
