Abstract

The invention relates to a handheld structure apparent crack measuring device, which comprises a telescopic bracket, a shooting module, an image processing module and a distance measuring module; the initial end of the telescopic bracket can axially stretch relative to the tail end; the image processing module is electrically connected with the shooting module, and the image processing module is used for performing apparent crack feature extraction on the structure apparent crack image within the target range acquired by the image acquisition module and numbering and storing the apparent crack features; and the distance measuring module is arranged on the shooting module and is electrically connected with the image processing module. Compared with the prior art, the crack feature information can be displayed, numbered, stored and uploaded to a database in real time, and compared with a traditional method, the device has the advantages of rapidness, standardization, informatization, precision, intellectualization and the like; and the crack information of the structure surface in a narrow space and an irregular plane can be obtained through the operation of an applicable person.

Description

technical field [0001] The invention relates to the field of structural disease detection, in particular to a hand-held device for measuring apparent cracks in structures. Background technique [0002] Due to the current bridge girder structure during construction, transportation and the entire operation period, cracks and diseases often appear on the surface of the structure due to reasons such as construction errors, transportation loss, and repeated loading of vehicle loads, which in turn affects the durability and safety of the overall structure. [0003] The traditional method mainly relies on manual visual inspection, and marks the found cracks with numbers. This method is inefficient, time-consuming and labor-intensive, and highly subjective. Moreover, due to poor lighting conditions in the box girder, it is easy to cause missed inspections and false inspections. [0004] CN207662806U discloses a hand-held bridge apparent disease detection device, which includes a thr...
