Research On The Technology Of Stereo Photograph Display Based On FPGA

The technology of stereo photograph display applies to research and development of photoelectric medical devices-3D TV endoscope that used in minimally invasive surgery, design the stereo camera display system based on FPGA technology in order to satisfying with 3Dendoscope, a three-dimensional battlefield observation system and three-dimensional movie technical requirements.Main content of stereovision study is stereoscopic display system hardware circuit design, VerilogHDL language programming, video chipconfiguration and initialization parameter control by I~2C bus. Stereo display system is based on the principle of binocular stereo vision video decoder chip ADV7402 used to achieve a variety of video input format, used the Lattice XP series of nonvolatile LFXP6C-3P208 chips and Verilog HDL language to program to realized two-channel video sampling, synthesis and processing. Complete design and functional simulation of frequency clock generator module, YC signal input control module, VGA signal output control module, SDRAM control module, the module video color space Transformation, video sync signal output module.The technology successfully applies to 3D endoscope, which supports multiple video input format, with brightness, contrast regulatory function. 100Hz VGA video signal output. LCD modulation screen and circularly polarized modulation using stereoscopic display technology.
