Abstract

The embodiment of the invention provides a high-precision map speed limit processing method and device, equipment and a storage medium, and the method comprises the steps: obtaining the speed limit information of each point speed limit in a road, and the speed limit information comprises a point speed limit value and a point speed limit type; aiming at each point speed limit, a dotting position of the point speed limit mapped in a high-precision map is determined, and the dotting position being used for representing a position corresponding to the point speed limit in the high-precision map; and according to the point speed limit value, the dotting position and the point speed limit type, performing batch processing on each point speed limit in the high-precision map into a linear speed limit. According to the method provided by the embodiment of the invention, the problem of low speed limiting processing precision in the prior art can be solved.

Description

Technical field [0001] The present application relates to the field of high-precision map speed limit processing, and more particularly to a high-precision map speed limit processing method, apparatus, device, and storage medium. Background technique [0002] With the rapid development of high-precision maps, more and more users use high-precision ordinary road maps to automatically drive. Since the road network density of ordinary roads is large, the scene is complicated, so in order to ensure efficiency and quality, high-precision map normal road speed limit information is an essential element. [0003] At present, the production of high-precision map ordinary road speed limitations requires artificial spot limit and line speed limit related information, and manually assigns the maximum speed limit value and speed limit information for each limit path line. [0004] However, the production of current regular speed limit information is complex due to complexity of ordinary road ...
