摘要
针对三维头盔显示器的结构与特点,提出了以PC为平台,以FPGA(现场可编程门阵列)为控制核心,以OLED(有机发光二极管)微显示芯片为图像源的三维头盔显示器USB2.0接口电路设计方案;并且在PC机上利用三维造型软件3ds MAX进行三维建模并从中提取出具有一定视差的双目图像,然后通过USB2.0接口将其按照给定的视频格式并行传送到左右两个微显示芯片进行显示,从而实现了双目立体视觉,验证了方案的可行性.
Considering the structure and characteristic of the head-mounted display （HMD）, this paper proposed a design of three-dimensional HMD＇s interface circuit based on USB2.0 specification, which use PC as the platform, FPGA （Fielded Programmable Gate Array） as the primary controller, micro-display chip in technique of OLED as the image source. For the feasibility verification of the theme, a 3D model, from which the binocular images with some parallax were extracted, was build by a 3D modeling software-3ds max on PC at first. After that, these images were transferred concurrently to the two micro-display chips for display through the interface of USB2.0 in specified video format. At last, the binocular stereo vision was realized consequently.
