Embodiment 1

[0066] Please refer to Figure 1-4 , Embodiment 1 of the present invention is:

[0067] The augmented reality interaction method based on a fixed trigger source provided by the present invention is mainly applied in the field of teaching, and the scene description of the embodiment is as follows:

[0068] 1. In the classroom, the teacher's podium and the students' desks are arranged in a ring along the circumference, and a trigger area 7 is set on the ground in the center of the ring, and a trigger image is set on the trigger area 7; the characteristic degree of the trigger image It is recommended to reach 5 stars (that is, judged by Qualcomm Vuforia). There is no limit to the production method of the trigger image, and there is no limit to the fixation method of the trigger image (it can even be designed to be flexible and disassembled). The size of the trigger image is determined according to the actual space of the classroom. When the diameter is between 2m-10m, the trigge...

Abstract

The present invention relates to the field of information technology, in particular to an augmented reality interaction method and system based on a fixed trigger source. The method includes: the preset mapping table stores the first image information of the first image and a plurality of interaction information groups corresponding to the first image information; the first interaction information group includes the first orientation information and the The first interaction information corresponding to the first orientation information; acquiring the second image, if it is recognized that the feature points of the second image match the feature points of the first image, acquiring the interaction information group corresponding to the first image information The second interaction information group in the second interaction information group; extracting the second interaction information with the same orientation from the second interaction information group; superimposing the second interaction information with the second image through augmented reality to obtain augmented reality information. Combined with the orientation information, the orientation of the interactive information after augmented reality is also different when displayed, which improves user experience and plays a role in promoting teaching interaction when applied in the teaching field.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an augmented reality interaction method and system based on a fixed trigger source. Background technique [0002] Augmented Reality (AR for short) is one of the research hotspots of many well-known foreign universities and research institutions. AR technology not only has a wide range of applications in fields similar to VR technology (virtual reality), such as research and development of cutting-edge weapons, aircraft, visualization of data models, virtual training, entertainment and art, but also because of its ability to The enhanced display output of the real environment has more obvious advantages than VR technology in the fields of medical research and anatomy training, precision instrument manufacturing and maintenance, military aircraft navigation, engineering design, and remote robot control. [0003] The Chinese patent document with application number 2015...
