Development Of Binocular Camera Based On FPGA

With the rapid development of computer vision, its theory and technology have been greatly enriched and binocular vision has always been a very important branch in the field of computer vision and its heat and status been rising in recent years. Binocular camera system as a specific form of binocular vision, the scope and prospects of application by the industry researchers attention. We can see binocular vision system more and more in the smart car, industrial testing, medical robots, service robots and even aerospace and other fields.With the increasing complexity of binocular vision applications and the increasing role of binocular vision, the requirements for its function and efficiency also increasing. The traditional binocular camera has been difficult to meet the practical needs of modern applications, so the development of a high efficiency,low power, lightweight, low cost binocular camera is a trend and very necessary choice.In this paper, the traditional binocular vision system is analyzed and studied,and the advantages and disadvantages of each scheme are compared. The design idea and optimization scheme are clarified. From the hardware system, the field-editable gate array (FPGA) as the computing platform, the image processing and local computing work. FPGA gives full play to its rich hardware and logic resources to enhance the overall operation and computational efficiency of binocular camera. And it can reduce the time of binocular camera system of work.And achieve the binocular camera system optimization.The main work of this paper is as follows: 1) Research and choose MT9V034 of Micron Technology Company as the image acquisition unit and complete the schematic diagram and PCB design of its peripheral circuit; 2) Using Xilinx's All Programmable SoC Zynq 7000 platform as the processing core of the binocular camera, and complete its core working circuit, external memory circuit and interface circuit schematic and PCB design; 3) Complete image transmission and caching software system design; 4) The design and implementation of the camera calibration and image distortion correction method for the binocular camera are completed.Finally completed the prototype production and debugging. The experimental results show that the binocular camera based on FPGA has low power consumption,small size, relatively low cost and high real-time performance, which meets the design target and application requirement.
