The intelligent monitoring system is now the cutting-edge application of the electronic information technology in the field of deformation monitoring in the world. A dangerous rock motion deformation image is acquired by a motion image processing technology, and the visual function of human beings is simulated by combining image processing and computer vision, so as to acquire dangerous rock deformation information and realize intelligent early warning. By adopting the method of the invention, dangerous rock deformation feature real-time monitoring and alarm can be realized. The method can make up for the defects of the existing method such as high cost and incapability of real-time monitoring or weak representativeness of monitoring points, and can provide dangerous rock deformation monitoring data and alarm for engineering geology, mining engineering and other related fields.

Description

technical field [0001] The invention belongs to the technical fields of geological engineering and mine engineering, and in particular relates to a method for extracting dangerous rock deformation information and alarming based on moving images. Background technique [0002] The monitoring of the deformation of the dangerous rock mass runs through the stages before, during and after the implementation of the prevention and control project. By closely monitoring the deformation dynamics of the dangerous rock mass, it is possible to predict the stability and deformation development trend of the dangerous rock mass, feedback the prevention and control construction design, guide the construction and inspect the prevention and control Effects play an important role. At present, the commonly used deformation monitoring methods include three-dimensional laser scanning monitoring, total station fixed-point deformation monitoring, and local crack deformation monitoring. The three-di...

AI Technical Summary

Problems solved by technology

The three-dimensional laser scanning monitoring has high precision, and can accurately and detailedly understand the deformation development trend of each point of the entire dangerous rock. However, due to the high cost of the laser scanner, it cannot be used for real-time monitoring; the total station can accurately understand the deformation development of specific control points However, due to the high cost, it cannot be used for real-time monitoring; local fracture deformation monitoring can monitor the deformation development trend of specific cracks in real time and provide early warning, but its representativeness is poor, and it cannot reflect the deformation development trend of the entire dangerous rock mass.

To sum up, there is currently no method for dangerous rock deformation monitoring that can monitor multi-point deformation and early warning in real time
