Vehicle intersection collision avoidance system and method based on unmanned aerial vehicle

Abstract

The invention belongs to the technical field of crossing of unmanned aerial vehicles and intelligent vehicles, and particularly relates to a vehicle intersection collision avoidance system and method based on an unmanned aerial vehicle. The system comprises a vehicle-mounted unmanned aerial vehicle takeoff and landing system, an unmanned aerial vehicle system and a vehicle-mounted industrial personal computer system. According to the vehicle intersection collision avoidance system and method based on the unmanned aerial vehicle, the traffic condition of an intersection can be monitored in the air in real time, vehicles in blind areas such as buildings, trees and the like at the intersection can be recognized, a driver is reminded to decelerate in time, the system conducts automatic emergency braking when necessary, collision accidents can be effectively avoided, and the active safety of the automobile is improved; and the unmanned aerial vehicle measures the angle between the vehicle and the corner point of the intersection, the airborne processor of the unmanned aerial vehicle is used for automatically filtering objects in the visible area of the vehicle, and only objects in the blind area of the vehicle are considered, so that the calculation amount of an algorithm can be greatly reduced, and the algorithm is faster.

Description

technical field [0001] The invention relates to the technical field of intersecting drones and smart vehicles, in particular to a system and method for avoiding collisions at vehicle intersections based on drones. Background technique [0002] Unmanned Aerial Vehicle (UAV) is an unmanned aerial vehicle that is controlled by radio remote control equipment, mobile phones, computers, etc. or by its own intelligent control system. It has a wide field of vision, small size, low cost, vertical take-off and landing, It can hover in the air and has strong wind resistance. With the rapid development of the UAV field, it has broad application prospects in the fields of transportation, military, aerial photography, plant protection, modern logistics, and disaster relief. [0003] With the progress of society and the improvement of people's living standards, automobiles have become a gradually popular means of transportation. In 2020, the number of cars in my country will reach 270 mi...

Problems solved by technology

The disadvantage of this system is that LTE-V communication is only applicable to pedestrians or vehicles with Internet of Vehicles communication equipment. Pedestrians need to wear smart devices and vehicles need to install on-board unit OBU (On boardUnit) to realize communication, which is not applicable to ordinary Pedestrians and vehicles; millimeter-wave radar is used. The penetration ability of millimeter-wave radar to trees and buildings is weak, and it is easy to produce blind spots, and cannot detect vehicles and pedestrians in the blind spots well.

The disadvantage of this system is that the electronic signs used are set at intervals in sequence, which consumes a lot of financial and material resources; it can only identify speed limit signs and signal lights, and is not suitable for intersections with no speed signs and signal lights; it cannot recognize pedestrians and cannot be avoided. collided with a pedestrian
