Multi-Screen 3 D Volumetric Displaying Technology
摘要
Abstract
Nowadays, displaying technologies are developing rapidly, they have not only confined to the two-dimensional plane,many kinds of three-dimentional displaying technologies have been emerged. This program did some research on volumetric displaying technology based on multi PDLC ( Polymer Dispersed Liquid Crystals )-screens,we took advantage of the switching character of PDLC-screens,used the method of time-divided displaying of multi screens and synchronized holographic projection to display a 3D graph. In this program,we analysed the response characteristics of PDLC screens, and designed the hardware of the circuit, the synchronization timing of PDLC-driving and projection, and the signal waveform of the PDLC-driving circuit. Furthermore we discussed the depth-of-field extraction algorithm based on Opencv. Finally we get 3D-graphs with different depth-of-field.关键词
