Embodiment 1

[0093] This embodiment provides a method for updating points of interest, such as figure 1 As shown, the method includes:

[0094] S100: Obtain preset road information of a specific type of road network element from a road library;

[0095] When updating the POI corresponding to the road network element, the road information of the road network element may be processed in batches according to the type of the road network element. Specifically, the road information corresponding to a certain preset road network element of a specific type is obtained from the road library. If the point of interest corresponding to the road network element of the roundabout type is to be updated, the Road information for road network elements.

[0096] S110: Generate a point of interest corresponding to the road network element according to the road information of the road network element;

[0097] Wherein, the road information includes road sections and / or road nodes, such as a road network e...

Embodiment 2

[0107] The point-of-interest update method provided in Embodiment 2 of the present application, such as figure 2 shown, including:

[0108] S200. Obtain road information filter conditions corresponding to a specific type of road network element;

[0109] In the embodiment of the present invention, road information filter conditions corresponding to various types of road network elements are pre-stored, for example, for a road network element whose type is a roundabout, the corresponding filter conditions include: the road section type is a roundabout, road name and alias contains at least names ending with keywords such as "roundabout", "roundabout", "junction", "interchange", "roundabout", "roundabout", "roundabout", "square". For a road network element whose type is a bridge, its corresponding filter conditions include: the road section type is a bridge type, and at least one of the road name and alias must end with "bridge", "separation", "road-railway", "overpass", etc. O...

Embodiment 3

[0122] The POI update method provided by Embodiment 3, such as image 3 shown, including:

[0123] S300. Obtain preset road information of a specific type of road network element from a road library, where the road information includes a road segment and a road node of the road segment.

[0124] S310. Splicing the road sections and road nodes of the road information of the road network elements to obtain a splicing object;

[0125] Specifically, according to the common road nodes owned by the road sections, the road sections are sequentially spliced ​​to obtain splicing objects.

[0126] For example, if the specific type is a roundabout, the process of splicing the road sections in the road information corresponding to the roundabout is as follows:

[0127] Since the driving direction of each road section in the road information that makes up the roundabout is not necessarily the same, when splicing, it may be that the head node FNode of the two road sections is the same and...

Abstract

The invention discloses an interest point updating method and a device. The interest point updating method comprises following steps: road information of preset specific type road network elements isacquired from a road library; interest points corresponding to the road network elements are generated based on the road information of the road network elements; interest points to be revised are searched in an interest point library, wherein the interest points to be revised are in a preset range of the positions of the interest points, and the types of the interest points to be revised and thetypes of the interest points are the same; if the interest points to be revised are found, updating of the attribute information of the interest points to be revised is carried out based on the attribute information of the interest points, otherwise, the interest points are added into the interest point library as newly increased interest points. The interest point updating method is capable of realizing timely comprehensive updating of road network element corresponding POI.

Description

technical field [0001] The present application relates to the technical field of information data processing, and more specifically, to a method and device for updating a point of interest. Background technique [0002] At present, in order to facilitate users to identify road network elements such as roads, tunnels, overpasses, toll stations, etc., POIs corresponding to the road network elements are stored in the POI database. The attribute information of the POI includes name, point of interest type, Coordinates, etc. In general, the POI type of the POI is consistent with the type of the corresponding road network element, and the name of the POI is the same as the name of the corresponding road network element. If a road network element is "XX roundabout", its corresponding The POI type of the POI is a roundabout, and the name of the POI is "XX roundabout". In the subsequent rendering of the electronic map, in addition to rendering the road network elements, POIs corresp...
