Description

Technical Field

[0001] The utility model relates to the field of AR technology, and specifically refers to an AR gesture recognition platform. Background Art

[0002] Augmented reality technology is a technology that cleverly integrates virtual information with the real world. It widely uses a variety of technical means such as multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, and sensing. It simulates computer-generated virtual information such as text, images, three-dimensional models, music, and videos, and applies them to the real world. The two types of information complement each other, thereby achieving "enhancement" of the real world.

[0003] During the AR experience, it is necessary to use a somatosensory recognition device to capture and collect the user's gestures, etc. The existing patent, such as an AR gesture recognition platform with application number 202221424496.1, includes a support frame, an adjustment bracket and a recognition platform. The support frame includes a fixed base, a support frame main body and a fill light strip. The top of the fixed base is fixedly connected to the support frame main body, one side of the support frame main body is provided with a groove, and the fill light strip is fixedly connected in the groove. The adjustment bracket includes a bracket main body, a rotating groove and a connecting protrusion. The top of the bracket main body is provided with a rotating groove, and the inner wall of one side of the rotating groove is fixedly connected to the connecting protrusion. The AR gesture recognition platform has an adjustment bracket fixedly connected to the top of the support frame, and the top of the adjustment bracket is rotatably connected to the recognition platform. The recognition platform has a built-in camera module. The user can perform gesture control on the recognition platform when in use. The camera module captures the user's hand movements and analyzes the user's gestures through the internal recognition chip. The support frame plays a stabilizing role, and the adjustment bracket can adjust the angle of the recognition platform.

[0004] Although the above patent analyzes the user's gestures through a recognition station, a single recognition station will have a recognition blind spot when recognizing and analyzing gestures, resulting in low gesture recognition efficiency and recognition failure. At the same time, when the user is standing and performing gesture recognition for a long time, the user becomes tired, resulting in low recognition efficiency. Utility Model Content
