Abstract

The invention provides a lane line-based vehicle positioning method, a calculating device, an intelligent vehicle, and a surface mark-based vehicle positioning method are provided. The lane line-basedvehicle positioning method includes the following steps: obtaining a visual map including lane line information; initially determining the current position of a vehicle in a world coordinate system;generating a top view having the same proportion and dimension with the visual map based on an image currently captured by a vehicle camera; determining the position of the top view on the visual mapbased on the initially determined current position of the vehicle, and determining a lane line part on the visual map, used for matching, as a visual map matching lane line mark based on the positionof the top view on the visual map; searching a lane line part matched with the visual map matching lane line mark on the top view; and determining a coordinate transformation relationship between thetop view and the visual map based on the matching lane line part on the top view and the visual map matching lane line mark in order to accurately determine the current position of the vehicle in theworld coordinate system.

Description

technical field [0001] The present invention generally relates to computer vision-based vehicle positioning technology, and in particular to a vehicle positioning method, computing device, computer storage medium and vehicle based on landmark information and visual maps on the ground. Background technique [0002] Intelligent driving, such as ADAS (Advanced Intelligent Driving Assistance) and unmanned driving, especially unmanned driving, has high requirements for position accuracy due to the safety of people and vehicles. The accuracy and real-time performance of the conventional positioning methods currently used are remarkable. insufficient. Contents of the invention [0003] The present invention has been made in view of the above circumstances. [0004] According to one aspect of the present invention, a vehicle positioning method based on lane lines is provided, which may include: obtaining a visual map including lane line information; initially determining that the...
