Method and device for binding points of interest (POI) and roads

Abstract

The invention discloses a method and device for binding points of interest (POI) and roads. Through the provided method and device, the POI and roads can be reasonably bound together. The method comprises the following steps: determining a road in a preset geographical range, which takes a POI to be bound as the center; calculating the vertical distance between the POI and the road, judging whether the vertical distance is smaller than or equal to a preset first distance threshold value; if the vertical distance is smaller or equal to the first distance threshold value, taking the node of the road as the start point and POI as the final point to design a first route, taking the POI as the start point and the node as the final point to design a second route; and if the length of the first route is smaller or equal to a preset second distance threshold value and the length of the second route is smaller or equal to a preset third distance threshold value, binding the POI to the road.

Description

technical field [0001] The present invention relates to the technical field of electronic maps, in particular to a method and device for binding roads with Point of Interest (POI). Background technique [0002] At present, in order to facilitate the user to intuitively understand which POIs are interested around the current driving road. The current practice is to bind POIs whose vertical distance to the road is less than or equal to a preset distance threshold (such as 100 meters) to the road in advance for each road. In the subsequent navigation process, according to the category entered by the user, the POIs that match the category entered by the user among the POIs bound to the user's current driving road are displayed to the user, so that when the user wants to go to a certain POI, he can navigate from the current location to that POI. POIs. [0003] The existing way of binding POIs to roads directly binds POIs whose vertical distance to the road is less than or equal...

Problems solved by technology

[0004] Although some POIs have a short vertical distance to the road, the vertical distance does not reflect the actual length of the road from the user's current location to the POI. It is very likely that there is no closer road from the user's current location that can directly reach the POI. , but it takes a long way to drive to the POI, or even to the POI (for example, the POI is separated from the road by a river), therefore, the existing technical solutions directly make the vertical distance to the road less than or equal to the preset distance Threshold POIs are bound to this road. There is an issue of binding unreasonable POIs to roads
