Internet-of-things building three-dimensional real-time monitoring and analysis method based on photogrammetry principle

Abstract

The invention relates to monitoring methods and particularly relates to building monitoring. An internet-of-things building three-dimensional real-time monitoring and analysis method based on photogrammetry principle includes a monitoring and analysis method that comprises the following five steps: 1) selecting a monitoring point and a controlling point and performing monitoring; 2) calculating three-dimensional coordinates of the monitoring point; 3) calculating variation tendency of the three-dimensional coordinates of the monitoring point; 4) calculating the variation tendency of the to-be-tested building; and 5) backuping the variation tendency by means of internet-of-things. The method, compared with the prior art, can acquire a large amount of physical and geometric information of the to-be-tested building in real time at distance, and can complete safety monitoring of buildings without damage on the body of a building and interference on natural status of the building and under some severe environments and the like conditions. The whole monitoring process is non-destructive, high-effective, safe, reliable and low-cost.

Description

technical field [0001] The invention relates to a monitoring method, in particular to building monitoring. Background technique [0002] As the country strengthens the protection of cultural heritage, especially architectural heritage, and the improvement of safety standards for modern residential and office buildings, the demand for building monitoring related to ancient building monitoring and dilapidated building monitoring has gradually increased, especially for building tilt , settlement and other core elements of monitoring. At present, people usually use traditional surveying and mapping technology to carry out regular monitoring of the above content, but this monitoring method has the disadvantages of time-consuming, high cost, low efficiency, poor timeliness, etc., and is not conducive to follow-up analysis. Remote real-time monitoring based on other types of IoT sensing devices solves the efficiency and timeliness problems to a certain extent, but there are also p...

Problems solved by technology

At present, people usually use traditional surveying and mapping technology to carry out regular monitoring of the above content, but this monitoring method has the disadvantages of time-consuming, high cost, low efficiency, poor timeliness, etc., and is not conducive to subsequent analysis

However, remote real-time monitoring based on other types of IoT sensing devices has solved the problems of efficiency and timeliness to a certain extent, but there are also problems such as high cost, poor accuracy, difficult implementation, interference or even damage to buildings, etc.
