Map updating method, device, equipment and storage medium

Abstract

The invention provides a map updating method, device and equipment and a storage medium. The method comprises that data, including data of a second area to be updated, of a first area is obtained; thedata of the first area is compared with data in a map, and a position of the second area in the map is determined; and the position in the map is updated based on the data of the second area. Thus, the map can be updated locally, and the map updating efficiency is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of map technologies, and in particular, to a map update method, device, device, and storage medium. Background technique [0002] With the widespread application of autonomous driving technology, the scale of high-precision maps used in autonomous driving technology is also increasing, and high-precision maps are not static after generation, but need to be used when the environment changes. The environment data updates the original data. [0003] However, the data currently used for updating often have certain errors. If the map is updated directly based on these data, the updated map will often have errors such as twisted roads and inaccurate connections. Contents of the invention [0004] Embodiments of the present application provide a map update method, device, device, and storage medium, so as to realize partial map update and improve the accuracy and efficiency of map update.
