Embodiment Construction

[0034] The following will further describe the specific embodiments of the present invention in conjunction with the accompanying drawings, so as to understand the present invention.

[0035] See attached figure 1, a system based on unmarked augmented reality on images, which includes an image retrieval system, that is, a mobile phone camera is used to scan a scene, retrieve images appearing in a scene in a database, and find consistent images as retrieval results; and augmented reality The system is to render the video introduction corresponding to the image to the position of the image in the scene to perform reality augmentation.

[0036] A method based on unmarked augmented reality on an image, wherein the image retrieval uses an invariant descriptor ORB to detect and describe feature points on an image, and the specific process retrieval process is as follows:

[0037] Step 1. Use the invariant descriptor ORB feature point detector to perform feature point detection on e...

Abstract

The invention discloses a system and a method for carrying out unmarked augmented reality on an image. The system comprises an image retrieval system and an augmented reality system, and is characterized in that a scene is scanned by using a mobile phone camera, an image appeared in the scene is retrieved in a database, and an image, which is consistent with the image appeared in the scene, is searched to act as a retrieval result; and video introduction corresponding to the image is rendered to the position where the image is located in the scene so as to carry out reality augmentation. The system disclosed by the invention has the advantages that unmarked augmented reality on the image is carried out, the accuracy is high, the adaptive distance is great, and the system adapts to a lot of image sources.

Description

technical field [0001] The present invention relates to the field of digital application technology, relates to an image recognition technology, in particular to a system and method based on augmented reality without markers on images. Background technique [0002] As we all know, image recognition technology is a technology widely used at present, which judges the relevant information corresponding to the image by recognizing the features of the image. Such as barcode loading technology, each barcode has its specific character set; each character occupies a certain width; has a certain verification function; at the same time, it also has the function of automatic identification of information in different lines, and the processing of graphic rotation change points. For example, the two-dimensional code loading technology, the two-dimensional code is to use a specific geometric figure according to a certain rule in the plane (two-dimensional direction) distribution of black ...
