Abstract
A method, device, equipment and computer-readable storage medium for obtaining map data. The method includes: determining a vehicle position at a preset time interval; determining a target road section based on the vehicle position for each determined vehicle position; obtaining first high-precision map data corresponding to the target road section; updating second high-precision map data stored in a storage area based on the first high-precision map data, wherein the high-precision map data stored in the storage area is used to be called by an intelligent driving module. Through the present application, the high-precision map data stored in the storage area is only related to the target road section corresponding to the vehicle position, which greatly reduces the amount of high-precision map data stored in the storage area. On this basis, when the intelligent driving module calls it, the data processing pressure is relatively small, thereby reducing the consumption of computing resources.
