Abstract

The invention discloses a reference plane determination method and determination system. The reference plane determination method comprises the steps that a depth image is acquired; edge extraction is performed on the depth image so as to form an edge image, wherein the edge image comprises multiple plane figures; and the plane figures of the edge image are selected through screening so as to determine a reference plane. According to the technical scheme, the reference plane in a real scene can be determined so that a virtual coordinate system can be established based on the reference plane, and finally the objective of mutual fusion of virtual objects and the real scene can be realized. Therefore, the virtual objects and the real scene are mutually fused through the technical scheme so that the experience feeling of real-time matching can be brought to users, and the reference plane determination method and determination system have wearable portability and freedom.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and system for determining a reference plane. Background technique [0002] Augmented Reality (AR for short) is a new technology that "seamlessly" integrates real world information and virtual world information. Specifically, augmented reality technology applies virtual information to the real world, so that the real environment and virtual objects are superimposed on the same picture or the same space in real time, so that they can be perceived by human senses and achieve a sensory experience beyond reality. Therefore, augmented reality technology not only displays the information of the real world, but also displays the information of the virtual world at the same time, and the two kinds of information complement and superimpose each other. [0003] In the field of augmented reality, the optical see-through augmented reality system has the advantages of simpl...
