Abstract

The invention provides a vehicle locating method, vehicle locating devices and a vehicle. The method includes: acquiring an image collected by a vehicle camera at current time; recognizing the image,and acquiring road features; acquiring a feature window corresponding to the current time, wherein the feature window is a locating area of the vehicle on a navigation map at the current time, and road features and coordinate information thereof are set on the navigation map; carrying out matching on the road features in the image and the feature window; and determining locating information of thevehicle according to coordinate information, which corresponds to matching road features, when the matching road features corresponding to the road features exist in the feature window. Therefore, alocating area can be determined first on the navigation map according to satellite locating information of the vehicle, the locating area is smaller, the included road features are also fewer, thus the vehicle can be accurately located on the locating area, changing on lane lines is avoided, locating cost is low, an application range is large, locating accuracy is high, and use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle positioning method, device and vehicle. Background technique [0002] The current vehicle positioning method mainly uses the vehicle camera to collect the special marking image set in advance on the lane line, and then compares the special marking image features with the special marking image features set in advance on the preset map to determine the positioning of the vehicle information. However, in the above solution, different special markings need to be set on different lane lines and different sections of the lane line, which requires too many changes to the lane line, high positioning costs, and the above solution has a small scope of application and low feasibility. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the ...
