Volumetric 3D display device based on reciprocating image scanning and control method thereof

Abstract

The invention provides a volumetric 3D display device based on reciprocating image scanning and a control method thereof. The volumetric 3D display device comprises a vacuum shell, a display module, alinear reciprocating motion mechanism, an ultra-short focus high-speed projection device, a motion frequency detection device, a vacuum degree detection device, a motion control module and an upper computer, wherein the display module and the linear reciprocating motion mechanism are arranged in the vacuum shell. The motion components are positioned in a vacuum environment, the drag coefficient can be greatly reduced, operations can be performed at a higher scanning frequency, the 3D imaging resolution is increased, the device is small in mechanical vibration and noise, and the service life of the device is prolonged. The motion frequency detection device is used for detecting a real motion frequency of the device in real time, and the upper computer is used for updating display images ofthe high-speed projection device in real time according to a refresh ratio, so that the condition that the display effect is influenced by image distortion is avoided. The vacuum degree detection device is capable of detecting the vacuum degree information of the vacuum shell in real time, and the optimal motion frequency is provided for the system, so that the optional 3D display effect of the device is achieved.

Description

technical field [0001] The invention relates to the field of true three-dimensional display technology and automatic control technology, in particular to a volumetric three-dimensional display device based on reciprocating image scanning and a control method thereof. Background technique [0002] In recent years, with the rapid development of computer software, hardware and multimedia industry, computer stereo vision system has increasingly become the mainstream development direction of the next generation display field. Compared with two-dimensional display technology, three-dimensional display is more in line with people's daily binocular observation habits, can bring better viewing and immersive experience, and has been widely used in military, medical, aviation, advertising, entertainment and other industries Applications. [0003] Currently, three-dimensional display technologies can be divided into four categories: Glasses-based Stereoscopic, Autostereoscopic Displays...

AI Technical Summary

Problems solved by technology

However, there are two big problems with the linear reciprocating motion of the screen: the first is that its drag coefficient is very large, and high-frequency movement will bring greater noise and resistance; the second is that the linear reciprocating motion is a process that requires constant acceleration and deceleration , the load on the display screen and supporting mechanism is relatively heavy, which affects the performance of the entire system
