Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0041] Such as figure 1 , 2 The shown augmented reality system based on image feature matching of the present invention includes: an image capture unit, a feature storage unit, a model storage unit, a first feature extraction unit, a first feature matching unit, a second feature extraction unit, A second feature matching unit, a position marking unit, an image processing unit, an image display unit, and a feature tracking unit.

[0042] The image capture unit captures the target image of the target object, and the first feature extraction unit extracts natural features of the target image. The feature storage unit stores multi-scale features of multiple feature files, and the model storage unit stores at least one model corresponding to the feature files. Multi-scale featur...

Abstract

The invention relates to a reality augmenting system and method based on image feature matching. By means of the matching technique of processing an image according to natural feature information of the image, the identity-free reality augmenting technology for multiple templates is achieved. In the feature point matching process, the error-removing matching algorithm is used, so that the accuracy of image matching is improved; feature parameters are extracted twice through the coarse-to-fine strategy; when matching fails or tracking fails, a system just needs to execute coarse feature extraction, so the execution speed of the system is increased; in the matching process of feature points of a target image and feature points of an identity image, the tracking algorithm is used for estimating the positions of the matching feature points of a next frame according to the currently matching feature points to obtain feature point pairs which change stably, so that the stability of model display is guaranteed, and user experience is improved.

Description

technical field [0001] The present invention relates to an augmented reality system and method, in particular to an image feature matching based augmented reality system and method. Background technique [0002] Augmented reality uses computer graphics technology and visualization technology to generate virtual objects that do not exist in the real environment, and accurately "places" the virtual objects in the real environment through image recognition and positioning technology, and integrates the virtual objects with the real environment with the help of display devices. And present a real visual experience to the user. Augmented reality technology uses markers to establish a virtual three-dimensional space, and markers play a role in connecting virtual space and real space. According to the category of markers, it is currently divided into two types: Marker augmented reality technology and Markless augmented reality technology. Compared with the augmented reality techn...
