【摘要】 从计算机视觉系统的基本体系结构出发 ,指出了计算机视觉系统要实现的主要功能 ,从理论上探讨了计算机视觉系统在硬件实现层次上存在的问题。进一步以立体视觉的应用要求为例提出了以现场可编程门阵列 (FP GA)为核心芯片的视觉处理系统。因为FPGA具有极强的可重构性 ,可承担部分原来由上位机软件完成的运算 ,增强了视觉处理的实时性。其应用于计算机三维立体视觉系统中 ,作为前端的图像采集器和视觉协处理器取得了良好的效果。更多还原

【Abstract】 Studied in accordance with computer vision system, this article puts forward the major problems existing in the hardware embodying levels of vision system. Then it explores new ideas in resolving these problems, and puts forward a vision processing system based on FPGA in the need of stereo vision system. As FPGA can be reconstructed freely, it can take charge of some computing work to strengthen the real time issue of visual processing. The system can be well applied to 3-D stereo vision system as a front-end graphic grabbing device and co-processor.更多还原
