The invention discloses a method for identifying a pavement pit slot and a device thereof based on the pavement pit slot which can be obtained by binocular vision or the three-dimensional characteristics of the length, width, and depth of a protrusion. By combining a suspension displacement sensor and a driving record device, the position of the pit slot or the protrusion can be quickly located. Adata image of a binocular camera in the section can be obtained directly from a calculation unit according to the location of the pit slot or the protrusion by the driving record device in the post processing, the problems that three-dimensional spatial information of the pavement pit slot is difficult to obtain and a position of the pavement pit slot cannot be located in the prior art are solved. According to the method for identifying the pavement pit slot and the device thereof, the three-dimensional spatial information of the pavement pit slot is obtained, and the position of the pavementpit slot can be located accurately and quickly.
Description
technical field [0001] The invention belongs to the technical field of road detection; in particular, it relates to a method and a device for identifying road surface potholes. Background technique [0002] At present, urban roads, expressways, and bridge pavements are all paved with asphalt. Due to the effect of driving load and the influence of natural factors, various damages are gradually formed on the road surface, among which road pits have the greatest impact on the ride comfort of cars. , but also affect driving safety. Therefore, the importance of detecting potholes on asphalt pavement as early as possible is self-evident. [0003] Most of the current road pothole detection is based on single-camera imaging. Although this method has greatly improved the detection efficiency, it is difficult to obtain the three-dimensional space information of the road potholes, and it is also unable to locate the position of the road potholes. Repairs are inconvenient. [0004] T...
