Gesture three-dimensional interactive projection technology

Abstract

The invention relates to a gesture three-dimensional interactive projection technology. One or more fingers of a user wear ring LED luminous tubes. Through a plurality of mark points, the technology simplifies processing, tracking, identifying, and positioning, and a system detects the luminous tubes instead of fingertip detection. Through a light-spot, special position device in a screen is pointed to. Through a six-axis acceleration sensor, an infrared signal generator, screen ultrasonic and infrared positioning grids, a dual-depth of field camera above the screen above are used for signal acquisition. Beneficial of the technology are that through signal processing of hand trajectory actions and correction of light-induced data, interaction with a holographic projection picture is realized, through a touch simulation unit, touch induction is realized, interaction true feeling is enhanced, and users can get tactile feedback of holographic images at the same time through a light sensor and a trajectory data sensor in a light-sensing data glove, and through continuously increasing sampling quantity and optimizing parameters, human gesture interactive projection is realized, so as to realize self-adaptation of individual crowd.

Description

technical field [0001] The invention relates to gesture stereoscopic interactive projection technology. Background technique [0002] For a long time, a sealing pen and a blackboard have been the standard equipment for teaching; with the development of projection technology and interactive technology, interactive projection has appeared, including two types of contact and non-contact. control effects (including pressure detection and light wave detection). Non-contact, using an optical mouse that can emit infrared signals (confirm the position through light source detection, angle and time calculation), but if you want to achieve non-contact, you need to carry an optical mouse, which is relatively inconvenient and cannot fully free your hands during speeches ; Secondly, the method of image recognition with the camera, but there are also occlusion problems (such as the surrounding environment, objects, and the speaker's own human body may have the problem of occluding the ca...
