【摘要】 与通常的传统的二维图像显示相比，立体显示技术能够显示深度信息，因而能更正确的认识事物的形状和运动情形，获得身临其境的感觉。传统的立体显示需要佩带偏振眼镜或头盔之类的辅助工具，十分不便。自由立体显示指的是运用光学、微电子技术、计算机技术等在二维显示平面上再现获取的立体左右眼图像对，以三维立体形式显示出来。自由立体显示技术无需佩带眼镜，具有更大的灵活性和实用性。本文研究的是基于FPGA的自由立体显示的硬件电路设计，该电路适用于双通道LVDS接口的17至20英寸的立体液晶显示器。本文介绍了FPGA及SDRAM的基础知识，在此基础上详细阐述了自由立体液晶显示的硬件电路设计方法和FPGA内部逻辑结构，并着重介绍了如何运用FPGA对SDRAM进行乒乓操作来完成像素数据的正确读写。在自由立体显示设计中，共有四种不同格式的图像，本文也对这四种图像源信号转换格式做了详细的介绍，并叙述了在自由立体显示硬件电路设计中，如何实现每一种3D信号格式的转换。本设计软件部分采用VHDL语言实现代码，只要通过适当修改代码即可应用于17至20英寸的立体显示器，具有较强的通用性。更多还原

【Abstract】 Compared with normal 2D display system, the 3D display system can save and record three-dimensional object with depth information, whichis helpful for recognizing the shape and movement of the object. Traditional 3D display needs assistant devices(special glasses,Helmet,etc.), so it’s very inconvenient. Autostereoscopic display technology can redisplay the lost depth information. Combining the technology of optics, electronics and computer, autostereoscopic display can present each viewer at least a pair of stereoscopic three-dimensional images. Autostereoscopic display helps achieve three-dimensional display without assistant devices, so it’s more flexible and practical.FPGA-based hardware circuit design for autostereoscopic display is presented in this paper. This paper includes the concept of FPGA and SDRAM.The design method of hardware circuit for autostereoscopic display and internal logic structure of FPGA were introduced in detail.It also interprets how to use FPGA to implement Ping-pong control of SDRAM to write and read pixel data correctly. There are four three-dimension display formats that were introduced in detail in this paper. And how to implement each three-dimension display format in the hardware circuit design for autostereoscopic is also illuminated.The software of this design was written with VHDL,which could be used universally into defferent size(17 to 20 inch) of autostereoscopic display through proper change.更多还原
