Embodiment Construction

[0051] As the main positioning system in the navigation and positioning system of the Internet of Vehicles, GPS has obvious advantages: the navigation error does not accumulate over time, the positioning accuracy is high, and it has authorization functions. However, when the satellite signal is weak or there is no satellite signal, GPS positioning cannot be achieved. Therefore, stable and accurate positioning cannot be achieved in GPS blind areas caused by high-rise urban areas, tunnels, underground garages, and bad weather. In addition, due to the low update frequency of GPS, accurate real-time positioning cannot be achieved when the vehicle is driving fast. Therefore, GPS is not suitable as a navigation and positioning system for vehicle terminals alone.

[0052] The inertial navigation system, as another main positioning system of the vehicle network navigation and positioning system, has the advantages of absolute confidentiality and no interference, fast update rate, high...

Abstract

The invention discloses a vehicle positioning method and system based on the Internet of Vehicles, belonging to the field of the Internet of Vehicles. The method includes: performing identity authentication on vehicles in the target area to obtain an authenticated vehicle; obtaining location information of the authenticated vehicle; and extracting location information of the target vehicle based on the location information of the authenticated vehicle, wherein the target vehicle is An interested vehicle among the authentication vehicles; based on the positioning information of the target vehicle, locating the target vehicle. The vehicle positioning method and system based on the Internet of Vehicles provided by the embodiments of this specification can realize stable, high-precision, and low-cost positioning, improve positioning efficiency, and completely solve the problem of GPS blind spot positioning.

Description

technical field [0001] The present application relates to the field of the Internet of Vehicles, in particular to a vehicle positioning method and system based on the Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a huge interactive network composed of information such as vehicle location, speed, and route. By collecting and sharing information, the interconnection between vehicles and vehicles, between vehicles and roadside infrastructure, and between vehicles and urban networks is realized. The Internet of Vehicles uses radio frequency identification (Radio Frequency Identification, RFID) and sensors to obtain information from the physical world, and then transmits this information to users or servers through the network to provide users with various services. [0003] Positioning technology is a key technology in the Internet of Vehicles. With the rapid development of the Internet of Vehicles, vehicle positioning has received more and more...
