Road concave-convex object detection method and device

Abstract

The invention relates to a road concave-convex object detection method and device, and relates to the technical field of intelligent traffic. The method comprises the following steps: firstly, acquiring an acceleration signal of each wheel of a vehicle, carrying out framing processing on the acceleration signal, and respectively calculating an acceleration difference and an acceleration multiple ratio of each frame of acceleration signal of each wheel; if the corresponding acceleration multiple ratio is larger than the corresponding preset acceleration multiple ratio threshold value, it is judged that the corresponding wheel passes through the concave-convex object in the corresponding frame, data information of each concave-convex object passed by the vehicle is obtained, and the data information of all the concave-convex objects is transmitted to a traffic department server; and the traffic department server evaluates each concave-convex object by using the data information of the concave-convex objects and the vehicle information of the corresponding vehicle. According to the road concave-convex object detection method provided by the invention, the problems that the detection effectiveness of the concave-convex object on the road is poor, the accuracy of the detection structure is low and the overall efficiency needs to be improved in the related technology are solved.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a method and device for detecting road bumps and convexities. Background technique [0002] At present, due to various reasons, there are often some bumps on the road. When a vehicle drives over these bumps, especially at high speed, it will cause discomfort to the occupants, and may also cause damage to the vehicle and its contents. , cause traffic accidents, and even cause loss of people's lives and property. Therefore, it is very necessary and important to detect the bumps on the road, especially the bumps on the highway. [0003] In related technologies, there are generally two ways to detect bumps and convexities on the road. The first way is to use manual visual inspection, which is a purposeless detection method that mainly relies on manual detection, which is extremely inefficient and requires The manpower, material resources, financial reso...
