Abstract: 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.
