Abstract

The embodiment of the invention discloses a path state information acquisition method and device and a storage medium. The method comprises the steps of collecting motion tracks of a plurality of objects, wherein the motion track comprises feature points corresponding to a plurality of time points; selecting a plurality of feature point pairs from the plurality of feature points according to the time points of the feature points, obtaining the speed of the object in the feature point pair to obtain a speed set corresponding to each object, fusing the speed sets of the plurality of objects to obtain the object reference speed of the path where the motion track is located, and obtaining the path state information corresponding to the path according to the object reference speed of the path.According to the scheme, the path state information acquisition efficiency can be improved.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a method, device and storage medium for acquiring path state information. Background technique [0002] Path status refers to the technical status of the existing road subgrade, road surface, structures and auxiliary facilities. For example, through the navigation on the driving application, the process of moving the target object from one place to another can be monitored, and the target object and the path can be combined to reflect the path state of the path in the area, so as to realize the path state acquisition. Intelligent. However, the current path state information acquisition method takes too long and has low efficiency. Contents of the invention [0003] Embodiments of the present application provide a path state information acquisition method, device, and storage medium, which can improve the efficiency of path state information acquisition. [0004] An emb...
