Abstract

The invention provides a crack measuring device, which comprises a data acquisition part, the data acquisition part comprises a first shell and a contact type image sensor arranged in the first shell, the first shell is provided with a measuring area, and the contact type image sensor acquires width data of a crack through the measuring area; the device also includes a data transmission line and a control part in signal connection with the data acquisition part through a data transmission line; the control part comprises a second shell and a distance sensor, the distance sensor is arranged in the second shell, and at least one part of the distance sensor is exposed out of the second shell so as to measure the length data of the crack. According to the invention, the problem of complex crack detection in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of crack measurement, in particular to a crack measurement device. Background technique [0002] At present, more or less cracks have appeared in many buildings, especially in some surviving ancient buildings, cracks are more common. At the same time, cracks in concrete bridges, steel bridges, etc. are also increasing. Cracks have become one of the most serious hazards in buildings, and the detection of cracks in buildings is becoming more and more important. [0003] At present, the commonly used method of measuring cracks is image detection, that is, taking a picture of a crack with a camera, analyzing and calculating the cracks in the image, and obtaining parameters such as the length and width of the crack. This detection method is relatively complicated, and the accuracy of the detection results is poor. Contents of the invention [0004] The main purpose of the present invention is to provide a cr...
