Visual monitoring method for mud-rock flow

Abstract

The invention relates to the computer vision and photographing measurement technology and discloses a visual monitoring method for mud-rock flow to solve the problems in the traditional technologies adopted in mud-rock flow monitoring schemes that a manual observation mode often brings poor timeliness and accuracy while a contact type detection mode is often high in cost and is not convenient for unified monitoring and management. The method comprises the following steps: a) deploying a monitoring platform for visual monitoring of the mud-rock flow wherein the monitoring platform comprises at least two cameras; marking the cameras after the deployment of these cameras; b) using the monitoring platform to measure the shape of the circulation area of the mud-rock flow so as to obtain the parameters of the shape prior to the occurrence of the mud-rock flow; and c) conducting real-time monitoring to the circulation area of the mud-rock flow by the monitoring platform; and when a mud-rock flow occurs, based on step b, obtaining the parameters of the circulation area shape of the mud-rock flow as well as the changing amount of these parameters so as to calculate for the mud-rock flow related data. The invention is suitable for mud-rock flow monitoring.

Description

technical field [0001] The invention relates to computer vision and photogrammetry technology, in particular to a visual monitoring method for debris flow. Background technique [0002] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain. Debris flow is a common mountain disaster. Its movement process is between landslides, landslides and floods. It is characterized by suddenness, fast flow, large flow, large material capacity and strong destructive power. [0003] my country is a country with frequent occurrence of debris flow disasters, especially during the flood season every year, which often destroy roads, railways and other transportation facilities and even villages and towns, causing large casualties and economic losses to the local area. Therefore, debris flow monitoring technology has...
