The present application discloses a method, device and equipment for updating road network information, wherein the method includes: determining the first tensor currently corresponding to the target road section according to the acquired driving trajectories of multiple vehicles; according to the road network data corresponding to the target road section, Determine the second tensor corresponding to the target road section; input the first tensor and the second tensor into the preset network model to determine whether the first tensor matches the second tensor; if the first tensor matches the second If the quantity does not match, update the road network data of the target road section according to the first tensor. This application realizes the automatic detection of whether the road network information changes by collecting the driving track of the vehicle, and automatically updates the changed part when the road network information changes, thereby improving the update efficiency of the road network information. And it can shorten the cycle, which brings convenience to the user's travel.
Description
technical field [0001] The present application relates to the technical field of information processing, in particular to a method, device and equipment for updating road network information. Background technique [0002] With the progress of urbanization and rapid economic development, the update rate of road network information is gradually increasing. At present, when updating the road network information, it is usually completed according to the road network change data reported by the user. Due to the low efficiency and long cycle of the data reported by the user, the update of the road network information always cannot keep up with the actual road network changes. affect user travel. Contents of the invention [0003] This application provides a road network information update method, device and equipment, which are used to solve the problem of updating road network information in related technologies. Due to the low efficiency and long period of data reported by us...
