摘 要:现如今随着科技的进步,显示技术已不仅仅局限于二维的平面中,各种三维的显示技术层出不穷。本项目对基于多块PDLC(聚合物掺杂液晶[1])屏幕的立体显示技术进行了研究,利用了PDLC屏幕的开关特性,采用多屏幕分时显示,同步的全息投影的方法,显示出三维的图像。实验中分析了PDLC屏幕的响应特性,设计了屏幕的驱动电路的硬件、时序和波形,探讨了基于Opencv的景深提取算法。最后获得了有一定景深的三维图像。
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.
