Abstract

The invention provides a reality enhancement method and a reality enhancement system. The method comprises: according to a shot image of a user in front of a projection screen, determining first coordinates of each point on the image of the user on the projection screen in a realistic coordinate space; converting the first coordinates into second coordinates in a view plane coordinate system where the user is disposed; converting the second coordinates into third coordinates in a projection coordinate system where the projection screen is disposed; and displaying a set image or video at a position corresponding to the third coordinates. In such a way, it is seen by audience that the user in front of the projection screen is superposed with a virtual image on the projection screen, and the reality enhancement effect is improved.

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 effect. For example: teaching, through novel and rich image effects, it is more conducive to enhancing students' interest a...
