Abstract

The invention discloses a positioning method, which comprises the steps of obtaining a local semantic map based on an initial position; determining a local plane based on the local semantic map; determining a conversion matrix Tp of a global coordinate system O1 and a coordinate system O2 of a local plane; and determining vehicle positioning based on the conversion matrix Tp. According to the invention, the plane assumption is used as a constraint and is applied to the positioning process, so that the positioning precision, the positioning robustness and the success rate are improved.

Description

technical field [0001] This application relates to the field of unmanned driving, in particular to a positioning method, device, electronic equipment and storage medium. Background technique [0002] With the development and popularization of intelligent driving, various application scenarios also put forward higher requirements for its key technologies, especially positioning technology. The current mainstream positioning technology includes GPS positioning technology, positioning technology based on external facilities such as base stations, and positioning technology based on vehicle sensors such as lslam and vlsam. The above technologies have their own advantages, disadvantages and application limitations. In order to adapt to more and more extensive and complex application scenarios, the industry is currently paying more and more attention to the use of advanced semantic information in the environment to improve the positioning effect. Can provide limited positioning c...
