摘要
传统的手势图像采集系统常常使用摄像机采集图像,然后再传送到分析计算机,进行分析。由于摄像机输出信号多为模拟信号,受信号传输衰减和噪声影响,传输距离受限,且必须在分析端安装视频采集卡,占用分析计算机部分CPU资源。基于此,本文提出一种基于ARM9的图像采集系统,直接在采集端将图像传感器输出的数字图像信号封装成IP包,通过网络传送给分析计算机进行分析。相对于传统图像采集系统,具有成本低、灵活组网、不受信号传输衰减和噪声影响等优点。
Vidicon is often used in traditional pantomime collecting system,the collected video is transmitted to analyzing computer to analyse. But most of output signals of vidicon are analog signals, they are easy to be weakened and disturbed by noise and have limited transmission distance. A piece of video collecting card must be installed in analyzing computer, it will occupy part of CPU resource. So in this essay,a video collecting system based on ARM9 is proposed, it will pack the out digital video signal of video sensor into some IP packages,and transmitting them to analyzing computer by network. Comparing to traditional video collecting system, it is cheaper, easier to organizing network, be immune to the effects of transmission and noise.
