Research On Data Processing Technology Of High Definition 3D Sensor

3D image sensor is a new type of visual sensor,it needs to be synchronized to collect and output the left and right eye image function.The high-definition left and right eye image collected by 3D sensor contains parallax information,it can effectively restore the depth of information,thus reducing the real three-dimensional scene.Based on the analysis of stereoscopic principle,this paper establishes the optical model of high-definition 3D sensor,develops the micro-electronic circuit of 3D sensor,and completes the logical design of 3D video data acquisition and display.The main work done in the paper research is:(1)Establishing high-definition 3D sensor optical model,and setting FPGA as the core components of high-definition 3D sensor system.The design logic algorithm completes the simultaneous configuration of the image sensor registers and the timing constraints of the 3D sensor signals so that they can collect the left and right eye views simultaneously.(2)The inner FIFO of FPGA and external SDRAM composed of "three buffer pool" structure to cache image data,the use of hardware logic to build 3D sensor synchronization acquisition,cache,dual view splicing and storage of large-scale digital circuits.(3)Completing the left and right stereo image of the splicing algorithm research,so that it can output left and right format 3D video through the image sensor interface.At the same time to complete the three-dimensional image on the flat display on the left and right format display.(4)Using the pulse subdivision method to effectively improve the image pixel capture and reassignment timing accuracy,to complete the left and right view pixel splicing.The three-dimensional view display on the naked eye 3D display correctly through the pixel sub-screen reassignment.Through the series of experiments,it is verified that the developed 3D sensor hardware logic algorithm can collect stereo images synchronously and can accurately splice and reconfigure.The hardware logic algorithm of 3D image sensor is correct,and the front-end design of dedicated IC is basically completed.
