Problems solved by technology

However, due to factors such as wide coverage of existing roads, limited labor costs, and difficulty in obtaining road change information, data production companies generally have a long update cycle for road databases; affected by users' subjective will, they will actively feed back road change information There are not many users, and it is not enough to provide enough update value for massive road information

Abstract

The invention discloses a method and a device for updating road information based on user track, wherein the method comprises the steps as follows: matching the user track collected by the server with the existing road according to the matching strategy, confirming the matching relationship between the user track and the existing road, each user track comprises a series of track points; inquiring the road database to obtain the road information of the first existing road, wherein the first existing road is the existing road having matching relationship with the user track; comparing the road information of the first existing road and the track information of the first user track, confirming the updating information of the first existing road, wherein the first user track is the user track matching with the first existing road. The updating information of the existing road can be confirmed timely by using the method and the device, the updating efficiency of the road information and the user experience are improved.

Description

technical field [0001] The present invention relates to the field of navigation, and more specifically, to a method and device for updating road information based on user tracks. Background technique [0002] In the navigation system, the server provides navigation services for users according to the road information stored in the road database. In order to provide users with accurate navigation, road information needs to be updated in time. [0003] In the prior art, the road database is usually regularly maintained and updated by the data production company, or the road information is updated by the server or relevant personnel according to the road change information actively fed back by the user. However, due to factors such as wide coverage of existing roads, limited labor costs, and difficulty in obtaining road change information, data production companies generally have a long update cycle for road databases; affected by users' subjective will, they will actively fee...
