Problems solved by technology

However, this invention does not take into account the suddenness of the road conditions ahead, and vehicles traveling on the road cannot obtain timely information on cracks, nor can they obtain reasonable driving route planning.
In the state of high-speed driving, it is difficult for the driver to have the reaction time to adopt the correct driving strategy, and there are potential safety hazards

Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein.

[0031] Such as figure 1 As shown, a driving path planning method based on road crack detection includes the following steps:

[0032] (1) Release and control the vehicle-mounted drone to fly according to the planned driving route of the vehicle, and use the vehicle-mounted drone to take pictures of the vehicle's traveling section;

[0033] (2) The UAV camera collects road information in front of the vehicle;

[0034] (3) Select the target detection area according to the road information in front of the vehicle collected by the drone camera, and identify whether there is a road crack in the target de...

Abstract

The invention discloses a driving path planning method and system based on road crack pit detection, and belongs to the technical field of road traffic safety. The driving path planning method is based on an image processing technology, and comprises the steps of firstly, collecting image information of a road section where a vehicle travels; identifying whether there is a road crack pit in the target detection area or not according to the obtained image information of the road section; judging whether the vehicle can safely pass through the crack pit or not by processing the collected crack pit geometrical parameters, crack pit position parameters and crack pit depth parameters, if not, conducting specific dangerous situation early warning, and planning a driving path of the vehicle according to the crack pit geometrical parameters and the crack pit position parameters so as to improve the road traffic safety.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety, and in particular relates to a driving path planning method and system based on road crack detection. Background technique [0002] When a vehicle is held up by the ground due to insufficient clearance between it and the ground, the situation where it cannot pass is called a clearance failure. Specifically, when the front of the vehicle touches the ground and makes it impossible to pass, it is called contact failure; when the rear of the vehicle touches the ground and makes it impossible to pass, it is called tail support failure. When there are cracks on the road surface, these two types of failures are prone to occur when vehicles pass through the pits, and there are potential safety hazards. Therefore, accurate road cracks are very important. [0003] The invention with application number 201710177036.0 discloses an automatic detection method for road potholes. In this method, tw...
