摘要
为生产体积小、成本低、功耗低、实时性高的视频监控系统,提出了一种基于SOPC的嵌入式视频监控方案。以台湾友晶公司的DE2FPGA开发板为硬件平台,以Quartus II 9.0和NIOS II 9.0为软件平台,实现了对数字图像传感器MT9M111输出的ITU-R BT.656视频流的采集、色彩空间转换、VGA显示器上实时显示。图像能够以640×480(30Hz)显示格式在VGA显示器上实时显示,具有截屏静止、存储等功能。与传统方案相比,该方案能提高系统的性能,减少软硬件设计周期,降低开发成本。
To produce a small size, low cost, low power consumption, real-time video surveillance system, an embed- ded video monitoring program based on SOPC is presented. The hardware platform of the design is Taiwan Terasic DE2 FPGA development board and the software platform is Quartus II 9.0 and NIOS II 9.0. It implements the acqui- sition of the ITU-R BT. 656 video stream which is output by the digital image sensor MT9Mlll, color space conversion and VGA monitor real-time display. The image（640×480,30 Hz） can be displayed on a VGA monitor in real time and has a screenshot stationary storage. Compared with traditional programs, the design can improve the performance of the system, reduce the hardware and software cycle and development cost.
