Method and device for displaying points of interest

Abstract

The embodiment of the invention provides a display method and display equipment for an interest point. The method comprises the steps of acquiring building block surface information of the interest points within a preset range according to the positioning coordinate point of the terminal, wherein the building block surface information comprises coordinates of boundary points of the building blockinformation; determining a projection range of the interest point on the screen of the terminal according to the position relation between the positioning coordinate points and the boundary point coordinates and a pre-built model observation projection MVP matrix; and displaying the information of the interest point on the screen of the terminal according to the projection range. According to themethod and equipment provided by the embodiment of the invention, the interest point information can be stably displayed on the screen of the terminal.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of map navigation, and in particular, to a method and device for displaying points of interest. Background technique

[0002] With the development of the map navigation technology, the user can check the position of the point of interest (Point of Interest, POI) through the electronic map on the terminal, and find the point of interest according to the position of the point of interest.

[0003] With the popularization of camera functions on smart phones, it becomes possible to develop augmented reality functions based on images captured by the camera. At present, there are products for real-scene navigation based on the images acquired by the camera, which can add the information of points of interest to the real-scene images, specifically project the center or key points of the points of interest onto the screen of the terminal, so that users can Identify points of interest.
