Method for acting on augmented reality virtual objects

Abstract

The invention relates to methods for acting on augmented reality virtual objects. According to the invention, the coordinates of a device for creating and viewing augmented reality are determined in relation to a real-world physical marker by means of analysis of an image from a camera of the device; a virtual camera is positioned in calculated coordinates of the device in relation to a physical base coordinate system in such a way that the marker, which is visible to the virtual camera, is positioned in the field of vision thereof, just as the physical marker is positioned in the field of vision of the device camera; a vector is calculated, which corresponds to a direction from the marker to the virtual camera in real-time mode; information is generated relating to all of the movements of the camera in relation to the marker, i.e. rotation, zoom, tilt.
