基于嵌入式VxWorks USB摄像头驱动的实现

Implementation of USB camera driver based on embedded VxWorks

摘要:

通过在Gene-8315开发板上加载嵌入式VxWorks系统对USB摄像头驱动进行研究。介绍了嵌入式VxWorks系统和USB摄像头驱动结构的特点，分析了spca5xx下USB摄像头视频采集的过程，裁剪并移植了spca5xx下ZC030x系列摄像头的采集过程，实现了基于嵌入式VxWorks系统下对Logitech USB摄像头的驱动和视频采集，并在显示器上显示驱动的过程和采集的结果。最后给出了对USB摄像头视频采集包头数据的分析。

Abstract:

Since few studies pay attention to the Universal Serial Bus(USB) camera driver in embedded VxWorks up till now, the VxWorks operating system is loaded to the Gene-8315 development board to study it in this paper. The features of embedded VxWorks and the driver structure of USB are introduced, the capture process of USB camera in spca5xx is analyzed，and the video capture process of ZC030x camera is cut and transplanted from spca5xx. The drive and video capture of Logitech USB camera is realized in embedded VxWorks and the monitor successfully displays the results．Finally the analysis of packet header data about the video capture is given.
