Building structure surface crack size automatic labeling method

Abstract

The invention discloses a building structure surface crack size automatic labeling method, which belongs to the technical field of electronic information and structure detection, and is used for solving the problem that the size data of a structure crack cannot be automatically and rapidly obtained and outputted at present. The specific technical implementation steps of the invention comprise A, collecting the image data; b, carrying out the image gray processing; c, simplifying the image into a trend line; d, determining a labeling point; e, adding a picture to the labeling software; f, determining a labeling position; g, obtaining the size information between the points; and H, carrying out size labeling and drawing. According to the invention, the labeling function of the AutoCAD software commonly used in engineering is ingeniously used; after the image is processed, the size labeling in the length direction and the width direction is carried out, the achieved crack labeling methodhas the advantages of being high in automation degree, rapid in image drawing, high in result reference and the like, and the method has the advantages for the cracks with irregular shapes.

Description

technical field [0001] The invention relates to a method for automatically marking the crack size on the surface of a building structure, in particular, it can be applied to automatically process, mark and draw the cracks on the surface of a concrete structure building. Background technique [0002] Most of the architectural concrete used in modern engineering is a brittle material, which is prone to brittle fracture and cracking during its use. Under normal use conditions, if the cracking of the structure exceeds a certain limit, it will cause users to feel psychological discomfort when using it, and it will also affect the function of the structure; The damage effect will also be reflected in its cracking situation at the same time. In this regard, it is of great significance to accurately obtain the size of structural cracks to study the safety, durability and stability of structures. [0003] At present, the method used for on-site crack size measurement is mainly manu...

Problems solved by technology

Although this method is relatively simple to implement, its measurement accuracy is limited, and the result accuracy of this method is greatly affected by the subjective operation of engineers

In addition, there are potential safety hazards in the structure with obvious cracks, which is not good for the personal safety of the staff entering it or close to the area to be tested; the unstandardized operation of the operator will cause certain damage to the area to be tested and destroy its original appearance
