Three-dimensional display system based on spatial positioning

Abstract

The invention discloses a three-dimensional display system based on spatial positioning. The three-dimensional display system comprises a desktop three-dimensional display module and a spatial positioning module, the desktop three-dimensional display module comprises a binocular projection assembly and a three-dimensional host assembly. The space positioning module comprises a tracker positioningassembly and a base station positioning assembly; the tracker positioning assembly is connected with the base station positioning assembly and the three-dimensional host assembly. The three-dimensional host assembly is connected with the binocular projection assembly. The tracker positioning assembly is used for feeding back the position of a viewer in real time and sending an ultra-wideband pulsesignal to the base station positioning assembly. According to the three-dimensional display system, the interactivity and the viewing angle of the display system can be enhanced, the application scene of three-dimensional display is expanded, meanwhile, multiple problems existing in the space positioning technology are solved, and the space positioning system which is high in positioning speed, wide in positioning range, low in cost and high in precision is achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a three-dimensional display system based on spatial positioning. Background technique [0002] Today, the 3D display technology is getting more and more attention, and various ways of realizing 3D display have been developed rapidly. Among them, 3D display technology has attracted widespread attention because it can truly restore the near-large and far-small and occlusion relationships in 3D scenes, and can provide smooth motion parallax. However, the existing 3D display application systems lack the spatial positioning function, resulting in extremely poor interactivity and lack of user experience, which seriously hinders the development of 3D display technology. [0003] At present, the spatial positioning technology in the industry mainly uses infrared optical positioning, laser positioning and visible light positioning. Infrared optical positioning uses mul...

AI Technical Summary

Problems solved by technology

Infrared optical positioning uses multiple infrared emitting cameras to cover the indoor positioning space. The positioning accuracy is very high and the range is large, but the cost of multiple high frame rate cameras is very high; laser positioning uses multiple lasers on the positioning light tower and the positioned object Inductive receiver calculates laser angle difference positioning, high positioning accuracy and wide range, but complex equipment structure and high cost; visible light positioning uses camera to capture active visible light of tracking points, although it has the advantage of low cost, but low positioning accuracy and narrow range
