Abstract

The embodiment of the invention discloses a vehicle positioning method and device, equipment and a medium, and relates to the technical field of intelligent driving, and the method comprises the stepsof obtaining the inertial measurement data of a vehicle at a current moment, the wheel speed of the vehicle and a target image of an environment where the vehicle is located; calculating a predictedpose of the vehicle at the current moment by utilizing the inertia measurement data and the vehicle wheel speed; calling a high-precision map comprising the information of the current environment of the vehicle based on the predicted position coordinates in the predicted pose; and correcting the predicted pose by using the target image and the high-precision map to obtain a target pose of the vehicle at the current moment. According to the embodiment of the invention, low-cost sensor deployment can be realized, the vehicle positioning precision is improved, and the method can be applied to a relatively wide positioning environment.

Description

technical field [0001] The embodiments of the present application relate to computer technology, in particular to intelligent driving technology, and in particular to a vehicle positioning method, device, equipment and medium. Background technique [0002] At present, the solutions commonly used for vehicle positioning include: positioning methods based on Global Positioning System (GPS), positioning methods based on LiDAR (Light Detection and Ranging, LiDAR), and positioning methods based on Ultra Wide Band (UWB) base stations. positioning method, and a camera-based pure vision positioning method. [0003] However, the GPS system, lidar, and UWB base station involved in the above method have high cost in terms of hardware deployment. Although the cost of pure visual positioning based on the camera is low, the positioning accuracy cannot be guaranteed. Contents of the invention [0004] Embodiments of the present application disclose a vehicle positioning method, device, ...
