Problems solved by technology

The vision-based gesture recognition method can provide users with a more natural and direct human-computer interaction method, but it has space constraints. When encountering irresistible factors such as occlusion, it cannot be accurately recognized, and the visual method itself is unstable. Restricted by the background environment, the recognition accuracy is limited

Embodiment

[0076] Such as figure 1 As shown, the 360° floating three-dimensional display system synchronously projects images onto the high-speed rotating directional scattering screen 005 through the high-speed projector 003 to realize a 360° probeable floating three-dimensional light field display. Among them, the frame frequency of the high-speed projector is 18000fps, and the rotation speed of the directional scattering screen 005 is 30r / s, the directional scattering screen 005 rotates once to receive and project 600 images. The servo motor 006 under the directional scattering screen 005 drives the screen to rotate at high speed in the horizontal plane. The high-speed projector 003 is located directly above the screen rotation center, and the optical axis of the projector is coaxial with the screen rotation center to ensure that the projected image is not distorted. In this way, the system realizes the reconstruction of the light field of the display point and displays the real thr...

Abstract

The invention discloses a gesture interaction device and method for a 360° suspended light field three-dimensional display system. The gesture interaction device includes a wearable device worn by a user, an optical positioning device for collecting hand position information, and a device for processing And the processor that transmits the signal; the IMU sensor in the wearable device can detect the attitude information such as the acceleration of each finger, the bending angle and the rotation angle of the palm, and communicate with the processor through the Bluetooth module; the optical positioning device is controlled by a near-infrared camera Array and infrared marker points. Determine the position information of the hand through the infrared camera array, calculate the positional relationship between the finger and the three-dimensional image, detect the hand posture through the wearable device, communicate data with the processor, judge the gesture and control the image change of the display system to achieve the purpose of gesture interaction . The invention has the advantages of simple structure, accurate recognition and strong expansibility, and can be used for human-computer interaction of various light field three-dimensional display systems.

Description

technical field [0001] The present invention relates to the technical field of computer vision and gesture recognition, and in particular to a gesture interaction device and method for a 360° suspended light field three-dimensional display system. The device and method realize the user and the three-dimensional display system based on an optical positioning system and a wearable device gesture interaction. Background technique [0002] Vision is an important way for human beings to obtain information. Among the information that people obtain every day, 80% are obtained through vision. The two-dimensional display devices used more in daily life lack the depth information in the physical world, and the displayed images lack a sense of reality. The emergence of three-dimensional display technology has solved this problem very well. [0003] The 3D display technology can provide real 3D perception effects such as occlusion and perspective, giving the observer an immersive exper...
