Working method of holographic projection device on basis of gesture recognition

Abstract

The invention discloses a working method of a holographic projection device on the basis of gesture recognition. The holographic projection device comprises a computer, a display screen, a camera andan inverted pyramid projector, wherein the computer is connected with the camera and the display screen through data lines; the display screen is horizontally arranged; and the inverted pyramid projector is vertically installed on the display screen through a support. The working method comprises gesture recognition based on OpenCV and comprehensive information processing based on multiple threads. The invention aims to break through the traditional two-dimensional plane display information, and through OpenGL three-dimensional modeling, the model is displayed in a three-dimensional space by using a conventional holographic projection technology; and through OpenCV gesture recognition, the working method can realize the functions of controlling the three-dimensional model to rotate, zoom in, zoom out and the like, can be used for the aspects of problem display, process analysis and discussion, display interaction of three-dimensional images of an exhibition and the like, and brings brand-new, visual and three-dimensional experience to life and office work of people.

Description

technical field [0001] The invention relates to a gesture recognition technology, in particular to a holographic projection technology based on gesture recognition. Background technique [0002] With the development of science and technology, more and more high-tech comes into view. The birth of 3D glasses, VR, AR and other glasses has broken the traditional two-dimensional imaging, but these devices are inseparable from the use of glasses. In order to realize the human-computer interaction function, the traditional gesture recognition is based on the tracker worn on the hand to realize the communication between the hand and the machine, but it is very inconvenient to wear. Holographic projection gets rid of the wearing of glasses, and the application location is no longer restricted. At the same time, it also presents the 3D structure more clearly for people, so that people can better analyze and solve problems. [0003] At present, this high-tech projection display method...

Problems solved by technology

[0003] At present, this high-tech projection display method has not been widely used in daily life. Projection devices based on similar principles have appeared on the market, but their practicability is not high, and they are only toys that can be used for entertainment.

Regarding holographic projection, domestic and foreign researches have been started a long time ago, and it has a history of several decades, but the process is relatively slow, and almost all display devices are only the display of the object itself without human-computer interaction. functions, display devices with interactive functions also require terminal control, and no devices and technologies have been found to directly control the display status through gestures
