Problems solved by technology

[0003] At present, multiple point lasers are used in the rut detection system. Since the position of the rut on the road surface may appear between the two lasers, it is impossible to accurately detect the rut data in the entire section of the road surface, which greatly affects the accuracy of the detection data. And the system The use process is complicated, which greatly affects the use of detection

Abstract

The invention relates to the field of road detection, in particular to a high-precision rut measurement device and measurement method based on monocular measurement. The high-precision rut measurementdevice comprises a line laser for illumination and a single high-resolution camera, moreover, the position relation between the line laser for illumination and the single high-resolution camera is optimized, so that the laser and the camera work cooperatively, moreover, through a monocular calibration method, the high-precision rut measurement device has the capability of collecting and processing data under various illumination conditions, meanwhile, the data testing precision is greatly improved, and the rapid and accurate measurement of a road surface rut is realized.

Description

technical field [0001] The invention relates to the field of road detection, in particular to a high-precision rutting measurement device and measurement method based on monocular measurement. Background technique [0002] Rutting refers to the longitudinal strip-shaped grooves on the road surface along the driving track, which are caused by the flow deformation, wear and subsidence of vehicles on the road. Rutting directly endangers the quality of the road surface, reduces the service life of the road surface, and shortens the maintenance cycle; in addition, during high-speed driving, if the direction is turned slightly, accidents that are difficult to deal with are prone to occur. Therefore, it is very necessary to regularly detect and repair road ruts. [0003] At present, multiple point lasers are used in the rut detection system. Since the position of the rut on the road surface may appear between the two lasers, it is impossible to accurately detect the rut data in th...
