Virtual information display method and device

Abstract

The invention discloses a virtual information display method and a virtual information display device, which belong to the field of Internet technologies. The virtual information display method comprises the steps of: extracting feature information of an image from the image acquired by a camera of a terminal in real time; if a feature database does not comprise feature information matched with the feature information of the image, acquiring current geographical position information of the terminal and orientation information of the camera, wherein the feature database is at least used for storing feature information and geographic position information of a plurality of targets; determining a matched target from the feature database according to the current geographical position information of the terminal and the orientation information of the camera; and acquiring and displaying virtual information of the matched target. The virtual information display method and the virtual information display device can improve the success rate of identification, especially in the case that the image comprises a plurality of targets or the target is a large-scale target such as a building or a scenic spot, and can prevent the occurrence of identification failure.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a virtual information display method and device. Background technique [0002] With the continuous development of Internet technology, the display of information on the terminal becomes more and more intuitive. For example, when the user needs to know a certain target, the terminal camera can be used to scan the target, and the target can be recognized. The virtual information corresponding to the target is displayed. The virtual information can be text information that introduces the target, or can be picture or video information. [0003] In the prior art, taking the target as a movie poster as an example, the method for displaying the virtual information is explained: the terminal camera scans the movie poster, and according to the characteristic information of the movie poster, the characteristic information of multiple targets is stored The feature information of the mov...

Problems solved by technology

[0005] The above-mentioned virtual information display method can only scan and identify targets with a small volume or area. For large targets such as shopping malls and buildings, it is difficult to scan the panorama at close range, which leads to the inability to effectively identify the target, which in turn cannot display the target. target virtual information
