Device and method for monitoring collapse of dangerous rock by video recording method

Abstract

The invention discloses a device for monitoring collapse of a dangerous rock by a video recording method. The device comprises a wireless night vision camera, markers, a signal receiver and a terminal computer, wherein the wireless night vision camera is fixed on the stable side of a crack of the dangerous rock; the markers are placed on the two sides of the crack of the dangerous rock; the wireless night vision camera performs video recording on the crack continuously and transmits to the signal receiver in a wireless manner; the recorded video is transmitted to the terminal computer remotely in a wireless manner through the signal amplification of the signal receiver; and the distance data between the markers and crack change data are automatically searched on video processing software and are further analyzed to draw a dangerous rock crack width change curve, so that collapse of the dangerous rock is monitored accurately in real time. The device has the advantages of wireless data transmission, real-time monitoring, simple structure, high monitoring accuracy, safety and easiness in operation, low requirement on the monitoring environment, capacity of acquiring image data at the first time during emergency, and the like.

Description

technical field [0001] The invention relates to the field of dangerous rock mass collapse monitoring and the technical field of video acquisition and processing, in particular to a device and method for monitoring dangerous rock mass collapse by using a video recording method. Background technique [0002] The safety monitoring of dangerous rock mass has been studied for a long time, and there are many monitoring methods. The traditional method adopts the intuitive micrometer observation method, which is to directly measure the crack width change of dangerous rock mass with a micrometer. The measurement method is intuitive and simple. However, there are problems such as poor precision and inability to record. [0003] With the further development of science and technology, GPS and INSAR three-dimensional laser scanners have also been introduced into the safety detection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the m...

[0002] The safety monitoring of dangerous rock mass has been studied for a long time, and there are many monitoring methods. The traditional method adopts the intuitive micrometer observation method, which is to directly measure the crack width change of dangerous rock mass with a micrometer. The measurement method is intuitive and simple. However, there are problems such as poor accuracy and inability to record

[0003] With the further development of science and technology, GPS and INSAR three-dimensional laser scanners have also been introduced into the safety detection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the monitoring requirements, and the cost is expensive. In the engineering application, it can not play a very good role in monitoring and predicting the collapse of dangerous rock mass.
