Vehicle auxiliary driving system and method based on unmanned aerial vehicle road perception

Abstract

The invention discloses a vehicle auxiliary driving system and method based on unmanned aerial vehicle road perception. The vehicle auxiliary driving system is provided with an unmanned aerial vehicle and a target vehicle, wherein the unmanned aerial vehicle comprises a UAV-mounted controller, a UAV-mounted camera module, a UAV-mounted wireless communication module, a flight control module and a UAV-mounted GPS module; the target vehicle comprises a vehicle-mounted controller, a vehicle-mounted camera module, a vehicle-mounted wireless communication module and a vehicle-mounted GPS module; the UAV-mounted wireless communication module is wirelessly connected with the vehicle-mounted wireless communication module; the UAV-mounted camera module collects first road condition information in front of and around the target vehicle; the UAV-mounted GPS module locates a position of the unmanned aerial vehicle; the UAV-mounted controller calculates a position and a speed of the unmanned aerial vehicle; the vehicle-mounted camera module collects second road condition information in front of the target vehicle; the vehicle-mounted controller processes the first road condition information and the second road condition information; and the vehicle-mounted GPS module positions the position of a target vehicle. According to the vehicle auxiliary driving system and the method, the unmanned aerial vehicle is introduced into the vehicle auxiliary driving system for road perception, and the situation perception capability is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle assisted driving, in particular to a vehicle assisted driving system and method based on road perception of an unmanned aerial vehicle. Background technique [0002] With the popularization and application of vehicle assisted driving technology, the UAV assisted driving system with larger coverage and stronger situational awareness has become an important solution in the field of vehicle assisted driving. At present, the vehicle auxiliary driving system mainly collects road condition information around the vehicle through various sensors installed on the vehicle to assist the driver to complete the driving task of the vehicle. However, this method has a big limitation that the sensors are often fixedly installed on the vehicle body, and the collected road condition information is limited to the surroundings of the vehicle body, making it difficult to determine the real-time traffic conditions that...

AI Technical Summary

Problems solved by technology

However, this method has a big limitation that the sensors are often fixedly installed on the vehicle body, and the collected road condition information is limited to the surroundings of the vehicle body, making it difficult to determine the real-time traffic conditions that are far away from the vehicle

At the same time, due to the limited viewing angle of the sensor fixed on the vehicle, it can only realize information collection within a fixed direction range. When there are obstacles or other vehicles blocking it, it is impossible to detect the road conditions in the blind spot of sight, and it is difficult to assist the driver to navigate the route. Planning and Security Alerts

[0003] On the other hand, in the existing UAV-assisted vehicle driving systems, the road condition information obtained by the UAV is rarely fused with the road condition information obtained by the vehicle itself.

[0004] Usually, the energy carried by the UAV itself is limited. H
