Abstract

The present invention provides an augmented reality method and an augmented reality system. According to the captured image of the user in front of the projection screen, determine the first coordinates of each point on the image of the user on the projection screen in the real coordinate space; transform the first coordinates into the first coordinates in the view plane coordinate system where the user is located Two coordinates; converting the second coordinates to the third coordinates in the projection coordinate system where the projection screen is located; displaying the set image or video at the position corresponding to the third coordinates on the projection screen. In this way, the user in front of the projection screen viewed by the audience is superimposed with the virtual image on the projection screen, thereby improving the effect of augmented reality.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an augmented reality method and augmented reality system. Background technique [0002] Augmented reality is a brand-new human-computer interaction technology. Using such a technology, the real on-site landscape can be simulated, and users can not only feel the "immersive" experience experienced in the objective physical world through the virtual reality system. Realism, and can break through space, time and other objective constraints, and feel the experience that cannot be experienced in the real world. Augmented reality systems are usually realized by display technology, tracking and positioning technology, interface and visualization technology, and calibration technology. The application of augmented reality technology in many fields has good results. For example: teaching, through novel and rich image effects, it is more conducive to enhancing students' interest ...
