Embodiment Construction

[0072] Assume that in the prior art, the missing time of positioning data is 20 minutes, a driving route planned by a certain route planning algorithm is 7.9 kilometers, and another driving route planned by another route planning algorithm is 7.9 kilometers. The path is 9.7 km. Of course, if other path planning algorithms are used, other possible driving paths can also be planned. However, the inventor of the present application has found that if one looks at the traffic status map when the vehicle is driving, it can be clearly found that there are congested road sections in the above two planned driving routes, for example, the congested road section lights up a yellow warning , and the traffic cost of the yellow warning is relatively large, so that the traffic time of vehicles on the above two planned driving paths may increase exponentially. Assume that according to the traffic conditions of the above two planned driving routes, it is calculated that the passing time of th...

Abstract

The embodiment of the invention discloses a method for repairing a driving route. The method comprises the following steps: a server reads a positioning data sequence of missing positioning data from a database storing positioning data, wherein the positioning data sequence includes a plurality of positioning data of the same moving object; the server plans driving routes for the missing positioning data in the positioning data sequence according to a path planning algorithm; the server uses the planed driving routes as candidate driving routes, and calculates a traveling time of each candidate driving route; and the server selects a driving route whose travelling time is the closest to the missing time of the positioning data as a missing driving route. Through the adoption of the method, the accuracy of repairing the missing driving route can be improved as much as possible, and the missing driving route that is as realistic as possible can be obtained. The embodiment of the invention further discloses a device for repairing the driving route.

Description

technical field [0001] This application relates to the field of computer applications, in particular to a method and device for repairing driving paths. Background technique [0002] In the current era of big data, vehicle positioning data and the driving route determined based on the vehicle positioning data have been widely used in various fields of social science and natural science, and play an important role. Wherein, during the driving process of the vehicle, the positioning device on the vehicle can regularly collect the positioning data of the vehicle, and then the communication device on the vehicle will regularly upload the collected positioning data to the server, and the server further uploads the positioning data uploaded by the vehicle Stored in a database, therefore, a large number of vehicle positioning data are stored offline in the database. In addition, the driving route of the vehicle can also be determined according to the positioning data of the vehicl...
