本文以“机车车辆轮对动态检测装置”为研究背景,以改进提升装置性能为目标,研究在Altera公司的FPGA(Field Programmable Gate Array)芯片Cyclone上实现图像采集控制、图像处理算法、JPEG(Joint Photographic Expert Group)压缩编码标准的基本系统。本文使用硬件描述语言Verilog,以RedLogic的RVDK开发板作为硬件平台,在开发工具OUARTUS2 6.0和MODELSIM SE 6.1B环境中完成软核的设计与仿真验证。 数据采集部分完成的功能是将由模拟摄像机拍摄到的图像信号进行数字化,然后从数据流中提取有效数据,加以适当裁剪,最后将奇偶场图像数据合并成帧,存储到存储器中。数字化及码流产生的功能由SAA7113芯片完成,由FPGA对SAA7113芯片初始化设置、控制,并对数字化后的数据进行操作。 图像处理算法部分考虑到实时性与算法复杂度等因素,从装置的图像处理流程中有选择性地实现了直方图均衡化、中值滤波与边缘检测三种图像处理算法。 压缩编码部分依据JPEG标准基本系统顺序编码模式,在FPGA上实现了DCT(Discrete Cosine Transform)变换、量化、Zig-Zag扫描、直流系数DPCM(Differential Pulse Code Modulation)编码、交流系数RLC(Run Length code)编码、霍夫曼编码等主要步骤,最后用实际的图像数据块对系统进行了验证。
