基于虚拟现实技术的三维影像智能显示系统嵌入式设计

Design of 3D image embedded intelligent display system based on virtual reality technology

以往的三维影像智能显示系统体积大、精度差,显示效果和同步性不能满足用户需求,针对这种现象,设计基于虚拟现实技术的三维影像嵌入式智能显示系统。虚拟现实技术使用Open GL和3ds MAX开发系统的数据采集与调试模块,使用VC++6.0开发显示模块,实现人与自然、人与人的视觉交互。对数据采集与调试模块的FPGA进行嵌入式设计,通过FPGA采集三维影像进行色彩调节,以压缩形式传导给显示模块的HI1257B芯片进行解码、去噪、画质增强和显示。实验结果表明,所设计的智能显示系统拥有显示效果逼真、同步性好的特点。

The display effect and synchronization of previous 3D intelligent image display system can＇t satisfy the user demand due to its large volume and poor accuracy. Therefore, a 3D image embedded intelligent display system based on virtual reality technology was designed. The virtual reality technology uses the OpenGL and 3ds MAX to develop the data acquisition and debugging module, and employs VC＋＋ 6.0 to develop the display module, so as to realize the visual interaction of human and nature, as well as human and human. The FPGA embedded design was performed for the data acquisition and debugging module. The 3D image is acquired through FPGA for color adjustment, and transmitted to the HI1257B in the display module in the compressed form for decoding, denoising, image quality enhancement and display. The experimental result shows that the designed intelligent display system has the characteristics of vivid display effect and high synchronization.
