Problems solved by technology

[0002] When the vehicle is driving on the road, different road sections may travel at different speeds. If there are potholes or bumps on the road, the vehicle will cause bumps if the vehicle does not slow down in time. It will cause safety accidents. Therefore, it is necessary to detect the position of the bumpy area on the road surface to remind other vehicles passing through the road section to slow down or remind road maintenance personnel to perform maintenance in time.
[0003] In the prior art, the road surface image is generally collected by the camera, and the bumpy area of ​​the road surface is roughly positioned. The location of the bumpy area of ​​the road surface is not accurate enough to effectively remind other vehicles to avoid the bumpy area.

Embodiment approach

[0045] In one embodiment, the method also includes:

[0046] When the vehicle passes the bumpy road area and the driving state data includes acceleration, the depth or height of the bumpy road area is determined according to the component of the acceleration in the vertical direction.

[0047] In practical applications, if the vehicle passes through a bumpy area on the road surface, the acceleration will change in the vertical direction compared to the vehicle driving on a flat road section. Therefore, after the acceleration of the vehicle is obtained, the component of the acceleration in the z-axis direction, that is, the component in the vertical direction, among the components of the acceleration in the three directions of the x-axis, y-axis, and z-axis can be used to represent the magnitude of the vehicle's bumps, so as to determine Depth of concave areas of road surface or height of raised areas.

Abstract

The invention provides a road bumping area detection method and device, electronic equipment and a storage medium, and relates to the technical field of computers. The method comprises the following steps: acquiring driving state data and vehicle orientation of a vehicle; determining whether the vehicle passes through a road bumping area according to the driving state data; and under the condition that the vehicle passes through the road bumping area, determining the position of the road bumping area according to the driving state data and the vehicle orientation. According to the technical scheme, when the vehicle passes through the road bumpy area, the position of the road bumpy area is determined through the driving state data of the vehicle and the vehicle orientation, the position of the road bumpy area can be accurately positioned, other vehicles are effectively reminded to take measures in time, and road maintenance personnel are reminded to carry out road maintenance in time.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to the field of data processing. Background technique [0002] When the vehicle is driving on the road, different road sections may travel at different speeds. If there are potholes or bumps on the road, the vehicle will cause bumps if the vehicle does not slow down in time. It will cause safety accidents. Therefore, it is necessary to detect the position of the bumpy area on the road surface to remind other vehicles passing through the road section to slow down or remind road maintenance personnel to perform maintenance in time. [0003] In the prior art, the road surface images are generally collected by a camera to roughly locate the bumpy area of ​​the road surface. The position of the bumpy area of ​​the road surface positioned in this way is not accurate enough to effectively remind other vehicles to avoid the bumpy area. Contents of the invention [0004] Th...
