Dangerous rock displacement monitoring method based on image modeling

Abstract

The invention provides a dangerous rock displacement monitoring method based on image modeling. The method based on computer image processing and modeling matching technologies can perform all-weather real-time monitoring on a displacement condition of a dangerous rock in a to-be-observed dangerous rock area, the method does not need the aid of a relatively expensive special detection facility and also the help of a relatively complex address exploration and survey method, and the method reduces monitoring cost and improves a scheme for monitoring a dangerous rock displacement through computer image processing. Through combinations with background image model and a scheme of matching processing for a monitored image, the method can effectively overcome influences of illumination and climate changes and a motion interference of a non-dangerous rock moving object; and, through a combination with a multi-matching determination mechanism, the method ensures accuracy of a displacement monitoring result of the to-be-observed dangerous rock, the method effectively solves the problems of difficult implementation, high monitoring cost and limited monitoring accuracy of real-time monitoring of dangerous rock safety in the prior art, and the method can be applied to an actual dangerous rock safety monitoring technology well.

Description

technical field [0001] The invention relates to the technical fields of dangerous rock protection and control technology and computer image processing, in particular to a dangerous rock displacement monitoring method based on image modeling. Background technique [0002] Dangerous rock is a potential collapse body, which is a relatively common structure in the field of geotechnical engineering. The main basis for its identification is: the location has a large height difference, or the slope is an isolated and steep mountain mouth, and there is a huge empty surface in front of the slope. The slope is concave and steep; cracks are developed in the slope body, the rock mass structure is incomplete, and there are a large number of cracks or weak zones that are consistent with or parallel to the slope; the development of collapses at the foot of the slope indicates that collapse activities have occurred; Cracks appear and expand continuously; rock mass creeps and rocks fall; the...

AI Technical Summary

Problems solved by technology

However, these dangerous rock safety monitoring methods often require the help of relatively expensive special detection facilities, or the assistance of more complex address survey methods, the monitoring cost is high, the processing time is slow, and it is difficult to achieve continuous real-time monitoring

[0005] The more commonly used technical means for continuous real-time monitoring is the dangerous rock displacement monitoring method based on computer image processing technology. Object detection, to realize real-time monitoring of the displacement of dangerous rocks, among which the more commonly used detection methods for moving objects are mainly background difference method and frame difference method; The influence of image chromaticity and brightness, and the inter-frame difference method can overcome the influence of illumination changes and climate changes to a certain extent, but it is vulnerable to non-dangerous rock moving objects such as swaying leaves and passing pedestrians. motion interference

Therefore, the monitoring accuracy of the dangerous rock displacement monitoring method based on computer image processing technology in the prior art is relatively limited, and the misjudgment rate is high, so it is difficult to be well applied to the actual dangerous rock safety monitoring technology.
