摘要
人脸检测是在图像中检测到人脸的位置,是当今科技领域攻关的热点技术。提出一种基于CMOS图像传感器和USB2.0的人脸检测系统。该系统利用CMOS图像传感器OV9620和USB2.0主控芯片CY7C68013设计高分辨率数字图像采集系统,由PC机采集图像数据,并对数据进行彩色恢复处理。在此基础上,完成视频图像中人脸的实时检测。文章阐述了该采集系统的软硬件结构设计和人脸检测的算法设计及实现。实验结果表明,该系统采集图像清晰稳定,传输速度为32.6Mbyte/s,图像处理速度为16 frame/s。实现了图像采集和人脸实时检测。
A human face detection system is proposed,based on CMOS image sensor and USB2.0. The system takes use of CMOS image sensor and USB2.0 CY7C68013 designing a high-resolution digital image acquisition. The image data is caught by PC, and it is necessary to process the data for restoring its color. On this basis, we can complete the real-time face detection on the video image. The article describes the hardware and software design of the acquisition system, and the algorithm design and realization of the face detection. The experimental results indicate that acquisited image is clear and stable. Speed of transmission is 32. 6 Mbyte/s, and speed of processing image is 16 frame/s. The image acquisition and real-time face detection have been realizated.
