A monitoring method and system based on a video monitoring measuring instrument and an inclinometer terminal

Abstract

The invention discloses a monitoring method for a video surveillance measuring instrument and an inclinometer terminal, comprising: recording initial inclination information, initial height information, real-time inclination information and height information of a point to be measured; measuring and recording the initial three-dimensional information of the point to be measured Spatial coordinate information, real-time three-dimensional space coordinate information; establish the initial three-dimensional digital model of the point to be measured, the real-time three-dimensional digital model of the preset time; calculate the change amount and the cumulative change amount of the measurement information of the point to be measured, and judge the change amount and the cumulative change amount If the amount is greater than the preset value; if so, issue a first-level early warning; add points to be measured, measure and record their three-dimensional space coordinate information, collect live video images in real time, and establish a real-time three-dimensional space digital model of the added points to be measured; The overall displacement range and displacement direction of the surrounding area; determine whether the displacement range is greater than the preset range; if so, issue a second-level alarm. The invention has the advantages of high monitoring accuracy and low false alarm rate.

Description

Technical field [0001] The invention relates to the technical field of engineering construction, in particular to a monitoring method and system based on a video monitoring measuring instrument and an inclinometer terminal. Background technique [0002] Under the influence of factors such as the unloading effect of the soil around the foundation pit, geological water infiltration, weather disasters and other factors, the retaining piles and supporting piles will be squeezed and tilted, or even collapse, and safety accidents may occur. In order to avoid accidents, accurate and real-time dynamic monitoring and early warning of the inclination angle and displacement of the retaining piles and supporting piles around the deep foundation pit are required to ensure construction safety. Similarly, in the protection and monitoring of ancient buildings, monitoring of dangerous buildings, and early warning of high slope collapse disasters, it is also necessary to accurately measure the inc...
