Abstract

The invention discloses a virtual object display device based on augmented reality, residing in a mobile terminal with a camera and a display screen, the device includes: an image capture module, adapted to capture images containing markers in the current real scene via the camera The location acquisition module is adapted to obtain current geographic location information; the feature extraction module is adapted to perform feature detection on captured images and extract feature points of markers in the images; the object matching module is adapted to extract feature points based on Determine the image template associated with the acquired geographical location information in the database and include the identifier; it is also suitable for obtaining the virtual object corresponding to the image template; the object display module is suitable for superimposing the image in the current real scene with the acquired virtual object, so as to The corresponding virtual scene is obtained, and the virtual scene is displayed via the display screen. The invention also discloses a corresponding method and system.

Description

technical field [0001] The present invention relates to the technical field of mobile augmented reality, in particular to a virtual object display method, device and system based on augmented reality. Background technique [0002] Augmented Reality (AR) technology is a new computer application and human-computer interaction technology developed on the basis of virtual reality technology. AR systems based on early architectures limited the user's range of motion and could not be applied to outdoor environments. With the maturity and development of smart terminals and mobile Internet technologies, many mobile Internet AR applications based on image recognition have emerged. Early mobile augmented reality systems required users to wear portable computers, power supplies, head-mounted displays, cameras, etc. with them. Such systems are bulky, heavy, expensive, and difficult to carry and maintain for a long time. The rise of small hand-held mobile devices (such as PDAs, smart m...
