Problems solved by technology
However, at present, a large number of researches focus on the measurement of rut shape, but few studies focus on the extraction of rut trajectory.
This is mainly due to the fact that although the vehicle-mounted laser displacement sensor can describe the deformation state of the rut, it will not be able to accurately locate the rut track if it detects the driving deviation of the vehicle.

The invention relates to an automatic detection and positioning method for the three-dimensional size of asphalt pavement ruts fused with multivariate data. The multivariate data are matched and fused. Aiming at the automatic detection of the three-dimensional size of road ruts, firstly, the cross-section line data is preprocessed by noise elimination and slope correction; then a method is proposed to locate the rut feature points by establishing the undeformed axis of the road surface; finally, according to the determined rut bottom point And the edge point, measure the width of the rut, the maximum depth, the slope of the rut wall, and the area of the depression. For the automatic positioning of road ruts, firstly, through the two-dimensional image of the road surface, the edge line of the lane is identified, and the center line of the lane is located based on the identified edge line of the lane; position; finally measure the offset of the left and right rut centers relative to the center of the lane. The invention provides richer information for road rutting detection.
Description
technical field [0001] The invention relates to the field of automatic detection and positioning of asphalt pavement rutting diseases, in particular to a method for automatic detection and positioning of three-dimensional size of asphalt pavement ruts integrating multivariate data. Background technique [0002] The automatic measurement of rutting has been widely used at home and abroad, mainly by installing laser displacement sensors at the front or rear of the detection vehicle to obtain road deformation information and extract rutting characterization parameters. For different data acquisition devices (point laser displacement sensor and line scan laser displacement sensor), the calculation methods of rutting characterization parameters are also different. [0003] The point laser-based rutting measurement method uses multiple point laser displacement sensors to obtain the longitudinal height value of a specific position on the road surface, thereby describing the road su...
