Abstract

The invention discloses a path planning method, a path planning device, equipment and a storage medium. The method comprises the following steps that: a to-be-served task edge is determined accordingto a service request; a task matrix is determined on the basis of the to-be-served task edge; and a planned path is determined according to the task matrix and a preset path planning model. Accordingto the technical schemes provided by the embodiments of the invention, the task edge is used as a minimum unit for providing services, and therefore, path planning efficiency can be improved, the conveying efficiency of an unmanned express delivery vehicle can be improved, and calculation cost can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer application technology, and in particular, to a path planning method, device, device and storage medium. Background technique [0002] With the development of modern life, the emergence of express delivery has made human life more convenient. At present, unmanned express vehicles have become the focus of research in the field of express delivery. Unmanned express vehicles need to automatically drive to customers to send and receive express delivery. Fixed, once it is full or unloaded, the unmanned express vehicle needs to return to the warehouse to load and unload the express. In order to make the unmanned express vehicle achieve the best delivery efficiency, each street is only served once and the total driving distance is the smallest. service path planning. [0003] In order to solve the above problems, in the prior art, each street to be served is used as the path planning un...
