specific Embodiment approach 1

[0029] Specific implementation mode 1. Combination figure 1 Describe this embodiment, the ground-air integrated vehicle networking system described in this embodiment, the system includes an aerial photography UAV system, a data center and a vehicle-mounted terminal, and the aerial photography UAV system includes a digital camera 1, an onboard processor 2, No. 1 GPS is positioned at device 3 and No. 1 wireless transceiver device 4;

[0030] The digital camera 1 is installed on the unmanned aerial vehicle, is used for photographing the image information of the road surface, and sends the photographed image information to the on-board processor 2;

[0031] The on-board processor 2 is used to receive the road surface image information sent by the digital camera 1 and the UAV position information sent by No. 1 GPS positioning device 3, and extract the vehicle position information on the road surface according to the UAV position information and the road surface image information, ...

specific Embodiment approach 2

[0045] Embodiment 2. This embodiment is a further description of the ground-air integrated vehicle networking system described in Embodiment 1. The No. 1 wireless transceiver device 4 and the No. 2 wireless transceiver device 5 both use DTU (DataTransferunit) wireless terminal equipment accomplish.

specific Embodiment approach 3

[0046] Specific implementation mode 3. The method for realizing navigation of the ground-air integrated vehicle networking system described in this implementation mode, the specific steps of the method:

[0047] Step 1: Use the digital camera 1 in the aerial photography UAV to take pictures of road surface image information at a frequency of once per second, and send the image information to the onboard processor 2; use No. 2 GPS positioning device 8 to check the location of the car where the vehicle terminal is located Carry out positioning; and send the destination address information of the vehicle where the vehicle-mounted terminal is located and the vehicle where the vehicle-mounted terminal is located to the data center through the No. 2 wireless transceiver device 5;

[0048] Step 2: The on-board processor 2 compares the received image information with the map corresponding to the image information, obtains the actual position of the vehicle on the road, calculates the a...

Abstract

A land-air integrated vehicle networking system and a method for realizing navigation thereof belong to the technical field of the vehicle networking. The problem of traffic congestion can be alleviated, the route of cars can be quickly planned, and the transportation efficiency and the capacity of the existing road network can be improved. The application of the aerial photography of the small unmanned aerial vehicle of the present invention obtains vehicle location information within a certain range through aerial photography and positioning, and sends the information to the vehicle-mounted terminal and data center in real time through the wireless transmission system. The on-board processor judges the running status of the vehicle according to the calculated acceleration value, and the data center obtains the vehicle location information, judges the road congestion within a certain time range, and sends the appropriate driving route to the on-board terminal. The invention is suitable for use as car navigation.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles. Background technique [0002] Due to the convenience of cars, the number of cars has continued to increase, leading to an increasing traffic flow in urban areas. The development of urban transportation has been unable to meet the growth of car ownership, and traffic jams have become a social problem. Moreover, the increase in car ownership has also brought traffic hazards, and traffic accidents have become a global public traffic safety problem. Therefore, to effectively alleviate traffic congestion, improve transportation efficiency and the capacity of the existing road network, and ensure driving safety are the problems we have to solve. Contents of the invention [0003] The invention proposes a land-air integrated vehicle networking system and a method for realizing navigation thereof, in order to alleviate the problem of traffic congestion, quickly plan vehicle driving routes...
