Method for rapidly obtaining building crack opening degree at low cost

Abstract

The invention provides a method for quickly obtaining the opening degree of a building crack at low cost, which comprises the following steps of: 1, marking a crack: numbering the crack, pasting a two-dimensional code beside the crack, associating two-dimensional code information with the crack number, and uploading the two-dimensional code information and the crack number to a server; 2, pictureuploading: photographing the crack and the two-dimensional code to enable the crack and the two-dimensional code to exist in the same picture, and uploading the picture to a server; 3, picture processing: the server performs image processing and analytical calculation on the uploaded picture; 4, a database is perfected, wherein the actual size of the crack obtained through calculation is stored ina server; and 5, data storage and feedback: judging whether the crack is at a dangerous point according to the trend of the crack, giving a pre-judged moment of the dangerous point of the crack, andsending the moment to a corresponding picture uploading terminal. According to the method, the trouble of traditional manual crack width detection is avoided, the cracking condition of the crack is monitored in real time through real-time shooting and uploading analysis of the two-dimensional code and the crack, a set of complete monitoring method is provided, and the method is simple, rapid, safeand efficient.

Description

technical field [0001] The invention relates to a method for obtaining the opening of building cracks quickly and at low cost, and belongs to the field of building crack monitoring. Background technique [0002] With the rapid development of China's economy and the rapid development of the domestic construction industry, the stock of existing buildings is very large. The problem that follows is the aging of buildings. The existing buildings have been used for decades due to temperature stress and Due to the influence of foundation settlement, there is inevitably the problem of cracking. The change of crack width can reflect the health status of buildings, so the monitoring of crack width change is an important monitoring work. [0003] At present, the traditional methods of crack monitoring still rely on manual on-site measurement of each building on a regular basis, and borrow simple tools such as magnifying glasses and width testers. Such a monitoring mode is not only ex...

AI Technical Summary

Problems solved by technology

Such a monitoring mode is not only extremely inefficient, but also cannot take into account the overall situation in the face of a large number of aging buildings. For some aging buildings that are in an unsafe state, there is a certain risk for operators to enter the construction work
