A road surface detection method and device

Abstract

The application of the invention discloses a pavement detection method and device. The method includes the following steps: GPS coordinates on a driving route and data elevation values corresponding to the GPS coordinates, of the pavement are automatically collected during the driving process of a user; a collecting point is set at every preset distance on the curve formed by the GPS coordinates; GPS coordinates and data elevation values corresponding to the collecting points are acquired; corresponding gradient values of the pavements between every two collecting points are calculated according to the data elevation values and the preset distances of the two adjacent collecting points; then whether the difference value between the two adjacent gradient values is larger than the preset value or not is judged; if yes, the area with the two adjacent gradient values larger than the preset value is confirmed to have sedimentation and require maintenance. Therefore, the technical scheme disclosed by the embodiment of the invention has the following advantages: site investigation by staff is not needed, and all that needed is to automatically analyze collected data to judge and obtain the GPS coordinate positions of the route requiring maintenance, so that labor cost is reduced, and the treatment efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of detection equipment, and more specifically, to a road surface detection method and device. Background technique [0002] After the construction of the road is completed, with the overload of vehicles, the passage of time, and the changes in the natural environment, the damage is gradually increasing. In order to ensure that the operation of the vehicle is not affected, it is necessary to regularly detect the damage of the road. Serious roads need to be repaired, so the maintenance cost of the road is also increasing day by day. Among them, the maintenance cost of the road mainly includes the maintenance cost and the maintenance cost. [0003] Among them, at present, when road inspection is carried out, manual inspection is mainly used for inspection. The inspectors inspect the scene and then judge whether the road surface needs to be repaired. However, this inspection method has the problems of ...
