Abstract

According to example embodiments of the present disclosure, a method, apparatus and computer-readable storage medium for updating an electronic map are provided. A method for updating an electronic map includes: obtaining a set of acquisition images acquired by an acquisition entity associated with a target map element in an electronic map, the target map element having an image of a target and a position of a target; performing inter-group matching between images; performing intra-group matching between the group of collected images; and updating the position of the map element to be updated associated with the target map element based on the inter-group matching, the intra-group matching and the target position. In this way, the positioning accuracy of map elements can be improved.

Description

technical field [0001] Embodiments of the present disclosure mainly relate to the field of electronic maps, and more specifically, to a method, device and computer-readable storage medium for updating electronic maps. Background technique [0002] At present, autonomous driving technology is attracting more and more attention. During the automatic driving process of the vehicle, it is necessary to use the electronic map to locate the vehicle. In order to ensure the accuracy of positioning and thus the reliability of automatic driving operations, there are usually high requirements for the drawing of electronic maps. For example, the accuracy of the electronic map is required to be as high as possible, because the accuracy of the electronic map will affect the positioning accuracy of the vehicle. It is also required that the relevant data of the electronic map be as accurate and comprehensive as possible. For example, detailed navigation and positioning information, such a...
