To realize better video acquistition,a video acquisition system was designed by using USB-camera and taking RT5350 of Ralink technology as the core chip,Linux as the embedded operating system kernel,and V4L2 as the video equipment kernel driver.This system was small in size and low in power consumption.In the paper, the hardware framework of the system,the flowchart and key code of software were given in detail.The experimental results showed that the videos recorded by the the system were clear and stabile,which meant that the system had good market value.
