Problems solved by technology

However, because the traffic signs and road signs used as samples are not evenly distributed in a large number, it is difficult to collect a sufficient number of samples at any time, which will inevitably lead to low positioning accuracy for unmanned vehicles in some time
In addition, in the case of insufficient light co

Embodiment Construction

[0039] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0040] figure 1 It is a flowchart of a vehicle positioning method according to an embodiment of the present disclosure. like figure 1 As shown, the method includes steps S101 to S105.

[0041] In step S101, the current position of the vehicle is acquired.

[0042] The step of acquiring the current position of the vehicle may be implemented through a Global Positioning System (Global Positioning System, GPS).

[0043] In addition, the step of acquiring the current position of the vehicle can also be implemented by a Global Navigation Satellite System (GLONASS), a Galileo Satellite Navigation System (Galileo Satellite Navigation System), a BeiDou Navigation Satellit...

Abstract

The invention relates to a vehicle positioning method and apparatus, and a vehicle and specifically relates to the field of vehicles. The method comprises the following steps: obtaining a current position of a vehicle; identifying a street lamp disposed in front of the current position of the vehicle; measuring a distance between the identified street lamp and the current position of the vehicle; by use of a map, based on the current position of the vehicle, determining longitude and latitude of the identified street lamp, wherein the map comprises latitude and longitude information and elevation information of street lamps at the two sides of a road; and according to the longitude and latitude of the identified street lamp and the distance, correcting the current position of the vehicle. The method can solve the disadvantages of too high cost and quite large errors existing in prior vehicle positioning arts and can accurately position the vehicle at a quite low cost.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a vehicle positioning method, device, and vehicle. Background technique [0002] At present, there are many high-precision positioning methods for unmanned vehicles. [0003] One of the methods is to use a high-precision Global Positioning System / Inertial Measurement Unit (GPS / IMU) to achieve through differential positioning technology and technologies such as lidar and millimeter-wave radar, but its cost is high. [0004] Another method is to collect multiple traffic signs and road signs as samples to calculate the distance between the unmanned vehicle and the traffic signs and road signs, so as to locate the unmanned vehicle. However, since the traffic signs and road signs used as samples are not evenly distributed in large numbers, it is difficult to collect a sufficient number of samples at any time, which will inevitably lead to low positioning accuracy of unmanned veh...
