Vehicle positioning method, device and equipment and storage medium

Abstract

The embodiment of the invention discloses a vehicle positioning method and device, equipment and a storage medium. The method comprises the steps: acquiring road network information and vehicle longitude and latitude information; according to the longitude and latitude information of the vehicle and the longitude and latitude information of the center line of the at least one road, obtaining the coordinates of the center line of the at least one road in a relative coordinate system; and according to the center line coordinates of the at least one road, ingeniously converting a coordinate system into a relative coordinate system relative to the center position of the vehicle based on the vehicle position coordinates, simplifying the calculation complexity of calculating the distance between the center point of the vehicle and the center line of the at least one road, and determining a target road where the vehicle is located in the at least one road according to the distance and the road width information of the at least one road. According to the technical scheme disclosed by the embodiment of the invention, the road positioning of the vehicle is realized, the communication pressure of the vehicle is reduced, and the safety of the vehicle-mounted terminal equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, and in particular to a vehicle positioning method, device, vehicle-mounted terminal equipment, and storage medium. Background technique [0002] With the continuous advancement of science and technology, automobiles are developing in the direction of intelligence, and among them, the positioning technology of automobiles has become an important research direction in the field of automobiles. [0003] For vehicle positioning, it is usually realized through the Internet of Vehicles platform, or with the help of installed third-party positioning software (such as navigation software); however, obtaining positioning information through the Internet of Vehicles platform requires the vehicle to maintain real-time remote communication with the Internet of Vehicles platform. This places extremely high requirements on the communication bandwidth of the vehicle terminal equipment....

Problems solved by technology

[0003] For vehicle positioning, it is usually realized through the Internet of Vehicles platform, or with the help of installed third-party positioning software (such as navigation software); however, obtaining positioning information through the Internet of Vehicles platform requires the vehicle to maintain real-time remote communication with the Internet of Vehicles platform, This places extremely high requirements on the communication bandwidth of the vehicle terminal equipment. At the same time, the communication between the vehicle and the Internet of Vehicles platform is restricted by environmental factors, and it is difficult to ensure the stability of the communication; and with the help of third-party positioning software, there is also the possibility that the communication is easily interfered. In addition, the third-party software itself also has certain security risks, and the security of the software is difficult to be guaranteed.
