A POI labeling method and device

Abstract

The invention discloses a POI labeling method and device. The method comprises the steps that two-dimensional data of indoor floors are obtained, and three-dimensional reconstruction is performed on the indoor floors according to the two-dimensional data to obtain a three-dimensional floor model; a screen display map corresponding to the three-dimensional floor model is determined according to a preset MVP matrix; according to the preset avoiding rule, labeling information of a POI in the indoor floors is added to a display region, corresponding to the POI, of the screen display map. According to the POI labeling method and device, the position information of the POI is reasonably and visually displayed, and the display effect of the indoor map and the user application experience effect are improved.

Description

technical field [0001] Embodiments of the present invention relate to electronic map technology, and in particular to a POI labeling method and device. Background technique [0002] With the development of interior design in urban buildings in a diversified direction, people are more and more eager to intuitively understand the distribution of indoor buildings and facilities through indoor maps. [0003] Most of the current maps are coordinates established and displayed on a two-dimensional plane. Each POI (Point of Interest, information point) contains information such as name, category, longitude and latitude, nearby hotels, restaurants, shops, etc., and the POI is marked as "ground ” label, its label information does not actually contain height information. When displaying POIs with the same latitude and longitude but different heights (that is, the same location on different floors), it will encounter a problem that is difficult to display. For example, see figure 1 A...

Problems solved by technology

In addition, in the display effect of existing indoor maps, there is still a problem that POI labels are mutually occluded so that users cannot recognize them.

[0004] Since most of the existing indoor maps are displayed using two-dimensional maps, users cannot intuitively obtain the indoor location information of POIs in the real world through the POI labeling information on the map

When users view the indoor map, they need to select the floor they want to view first. If the user is not familiar with the indoor facilities, they may need to view the floor by floor, which is time-consuming and not conducive to improving the user's application experience.

In addition, different providers of electronic maps have different interface definition styles. Users need to convert the marked information (such as floor symbols) into comprehensible location information in reality through brain reprocessing, so as to obtain the actual location of the POI. The POI display It is not intuitive enough. If the labeling information of POIs are still occluded so that users cannot identify them, it will further affect the user's application experience.
