Abstract

The invention relates to the technical field of pavement detection, and specifically relates to a pavement crack detection device and method. The invention aims at ironing out the defects of the pavement manual detection technology, improves the pavement detection efficiency, and provides the pavement crack detection device. Through the combination of an imaging module, a light supplement module and a processing module, the device carries out the segmentation of the threshold value of an image via a Sobel edge detection algorithm, so as to improve a clearer crack.

Description

technical field [0001] The invention relates to the technical field of road surface detection, in particular to a device and method for detecting cracks in the road surface. Background technique [0002] As the road has been exposed to the atmosphere for a long time, it has suffered from natural disasters, accident damage, crack wear, heavy load, overload, and human damage, etc., and road maintenance is urgent. In the past, traditional manual detection methods were used in pavement crack detection. With the development of highways and the increase of their quantity, this manual detection method can no longer meet the requirements of highway development. Contents of the invention [0003] The invention aims to overcome the defects of the existing manual pavement detection technology, improve the pavement detection efficiency, and provide a pavement crack detection device and a pavement crack detection method. [0004] To achieve the above object, the present invention ado...
