Abstract

The invention relates to an interactive holographic display system and method based on 3D dynamic touch, and belongs to the technical field of holographic 3D display and computer vision intersection.According to the invention, a real 3D image is reproduced in the air through the digital holographic 3D reproducing device. The touch detection device shoots a scene that a user dynamically touches a3D image in the air and transmits the scene to the main controller. The main controller detects a user instruction according to scattered light information when a user touches the aerial 3D image, andloads a corresponding hologram to the digital holographic 3D reproduction device according to the user instruction to reproduce a new aerial 3D image. According to the invention, dynamic touch interaction between a user and a plurality of 3D images reproduced in the air is realized, and the user can control the rotation direction and the rotation angle of the 3D images in the air through direct touch. Compared with a conventional non-touch interaction mode, the method can bring more real, freer and richer interaction experience to the user, and further improves the attraction to the user.

Description

technical field [0001] The invention relates to an interactive holographic display system and method based on 3D dynamic touch, and belongs to the cross technical field of holographic 3D display and computer vision. Background technique [0002] Human-computer interaction is developing towards a more natural and intuitive way, and the 2D screen touch method has become increasingly difficult to meet people's needs for real experience in the interaction process. At present, more researches are based on the gesture-based 3D interaction method, but the user cannot directly contact the interactive object in the gesture-based interaction method. Therefore, it is expected that the 3D display technology will be better combined with the user interface, and more interaction methods will be explored to provide a richer, more natural, and more realistic interactive experience. Contents of the invention [0003] The technical problem to be solved by the present invention is: the prese...
