Abstract

The invention discloses a high-precision map updating method, a vehicle, a server and a storage medium. The method comprises: extracting target semantic information from the acquired image and a pre-stored high-precision map; determining whether the target semantic information can be successfully matched with the data in the high-precision map or not; and when it is determined that the target semantic information fails to be matched with the data in the high-precision map, sending error information to a server, so that the server determines whether the high-precision map needs to be updated according to the error information, and receives map updating incremental data sent by the server, wherein the map updating incremental data is data sent when the server determines that the high-precision map needs to be updated according to the error information, and the high-precision map is updated according to the map updating incremental data. The high-precision map updating method is low in cost and high in updating efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the field of automatic driving, and in particular to a method for updating a high-precision map, a vehicle, a server, and a storage medium. Background technique [0002] The function realization of L3 level (conditional automatic driving) self-driving vehicles requires the use of high-precision maps. Traditional high-precision map collection relies on sensors such as lidar, camera, and high-precision integrated inertial navigation, and requires map collectors to have certain surveying and mapping qualifications and professional surveying and mapping capabilities. Therefore, the cost of data collection, production and maintenance is extremely high. Roads are constantly being built, and the update of high-precision maps is more important than the production of initial maps. Traditional map collection methods alone cannot meet the requirements of data updates due to factors such as cost constraints. [0...
