Embodiment Construction

[0052] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other under the condition of no conflict.

[0053] Many specific details are set forth in the following description to facilitate a full understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, and Not all examples.

[0054] Usually, once the connection status between roads in real space changes, the lane topology in the electronic map needs to be updated, and a new version of the electronic map is released. However, the period from the revision of the electronic map to the...

Abstract

The invention relates to a lane topology updating method and device, equipment and a storage medium. According to the invention, the production publisher publishes the lane topology update data, so that the application end can determine the target area corresponding to the lane topology change area in the existing electronic map, and the lane set composed of the lanes driving into the target area and the lanes driving out of the target area is obtained. And selecting at least two target lanes meeting a preset constraint condition from the lane set. And further, according to the lane topology change type, updating the topological relation of the at least two target lanes. As the lane topology update data is simple in structure, small in quantity, easy to mark and low in manufacturing cost, a production publisher can dynamically publish the lane topology update data in real time, so that an application end can immediately and quickly update the lane topology according to the lane topology update data, and the lane topology update efficiency is improved. Therefore, the new lane topology can be instantly and quickly applied by the application end.

Description

technical field [0001] The present disclosure relates to the field of information technology, and in particular, to a lane topology update method, device, device, and storage medium. Background technique [0002] With the continuous development of technology, users can install various types of application programs (Application, APP) on the terminal, for example, including travel applications. Travel applications can provide services such as route planning and navigation to users or to unmanned vehicles. [0003] However, the inventor of the present application found that once the connection status between roads in the real space changes, the lane topology in the electronic map needs to be updated, and a new version of the electronic map needs to be released. However, the period from the revision of the electronic map to the release is long, so that the new lane topology cannot be applied immediately. SUMMARY OF THE INVENTION [0004] In order to solve the above technical...
