摘要
在智能交通领域,车辆的违章检测是重要的技术。而视频检测算法基本上都是基于PC平台的软件检测,无论是从稳定性和价格等都是不可取的。结合最新的SOPC技术,提出了一种基于SOPC的视频检测技术。以Nios II软核处理器和外设IP核为硬件平台,结合A/D和D/A视频接口,以$C/OS为操作系统,实现了视频检测的硬件与软件结合的嵌入式检测技术,从而摆脱了PC的限制。最后通过具体的工程验证了设计的有效性,该方法具有高达82%的检测率,从而在智能交通领域发展有很好的市场前景。
In the field of intelligent transportation, violation vehicle detection was an important technique. Most of the video detection algorithms were software testing based on the PC platform, so need one IPC as a front-end detection part for the operation of detection platform, either stability or price not desirable. One video detection technology based on SOPC was proposed. In the device, the Nios Ⅱ soft CPU core and peripherals IP cores were embedded, and with A/D and D/A video interface. The μC / OS realtime operating system was replanted in it, and the detecting algorithm was also achieved in it. Finally, a project is designed to verify the validity of design, which shows that the method has high detection rate of 82% and would have good market prospects in the development of intelligent transportation field.
