Design of a ZYNQ-Accelerated Real-Time Template Matching System with OpenCV Integration

  • 摘要: 针对OpenCV在PC端部署存在的环境复杂、性能开销大及实时性不足问题,本研究提出基于ZYNQ平台的硬件加速方案. 通过改进传统模板匹配算法,采用多尺度模板金字塔增强尺度适应性,并利用Vivado HLS将C++算法封装为可综合IP核. 结合多媒体收发芯片构建硬件架构,通过AXI总线实现PS端控制与PL端加速协同,采用裸机程序驱动完成1080P视频的实时处理与显示. 实验结果表明:系统处理单帧图像耗时6.562 ms,逻辑资源占用率12%-24%,较PC端196 ms处理速度提升显著,HDMI接口可清晰输出处理后画面. 该方案有效解决了传统OpenCV嵌入式部署的实时性瓶颈,为复杂图像处理算法的硬件加速提供了可扩展的实现路径.

     

    Abstract: To address the challenges of complex deployment environments, high computational overhead, and insufficient real-time performance when deploying OpenCV on PCs, this study proposes a hardware acceleration solution based on the ZYNQ platform. The traditional template matching algorithm is improved by incorporating a multi-scale template pyramid to enhance scale adaptability. The C++ algorithm is encapsulated into a synthesizable IP core using Vivado HLS. A hardware architecture is constructed by integrating multimedia transceiver chips, enabling PS-PL collaboration via the AXI bus, and real-time 1080P video processing and display are achieved through bare-metal programming drivers. Experimental results demonstrate that the system processes a single frame in 6.562 ms, with logic resource utilization ranging from 12% to 24%, achieving a significant improvement over the PC-based implementation (196 ms per frame). The HDMI interface outputs processed video with clearly marked matching regions. This solution effectively resolves the real-time bottleneck of traditional OpenCV deployment in embedded systems and provides a scalable implementation pathway for hardware acceleration of complex image processing algorithms.
