Problems solved by technology

[0002] With the development of the road network, more and more roads are newly built, and the update of the map, that is, the road network information, needs to be completed by collecting data through manual surveying and mapping, which has problems such as low efficiency and long update time
As a result, the map cannot be updated quickly in places where the map needs to be used (such as navigation software, etc.), which affects the efficiency of travel

Embodiment Construction

[0033] The technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described examples are part of the examples in this application, not all of them. Based on the examples in this application, all other examples obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0034] As mentioned above, the update of road network information used in current navigation and other applications is usually achieved through data collection through manual surveying and mapping, which has problems such as low efficiency and long update time. For this reason, the present application proposes a road network update method, which can update the road network based on the user's location data, and can quickly and effectively update the road network information, thereby making it more convenient for the user to travel.

Abstract

The invention provides a road network information updating method. The method comprises the steps: obtaining the position information of a user; generating a movement track of the user according to the obtained position information of the user; comparing the movement track of the user with conventional road network information, and determining a new path which is not in the existing road network information in the movement track of the user; and writing the information of the new path into the road network information. The invention also provides a road network updating device. The method anddevice can achieve the updating of the road network information according to the movement track of the user, and there is no need of manual mapping, so the method and device are more convenient and timely.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and device for updating road network information. Background technique [0002] With the development of the road network, more and more roads are newly built, and the update of the map, that is, the road network information, needs to be completed by collecting data through manual surveying and mapping, which has problems such as low efficiency and long update time. As a result, the map cannot be updated quickly in places where the map needs to be used (such as navigation software, etc.), thereby affecting the efficiency of travel. Contents of the invention [0003] The example of the present invention provides a method for updating road network information. The method includes: obtaining the location information of the user; generating the user's movement trajectory according to the obtained user location information; comparing the user's movement traje...
