| 摘 要： | 根据某些特殊作业现场对视频监控的需求,研究了在嵌入式Linux系统下采用分散存储方式进行视频采集的方法.针对当前嵌入式Linux系统下视频采集一般仅采用V4L存在的问题,提出了一种在嵌入式Linux系统下同时采用V4L和SDL进行视频采集的方案.本文重点解决了在仅采用V4L情况下实时显示、时间信息的获取和事件处理难于实现或过于复杂等问题.实验结果表明,同时采用V4L和SDL在嵌入式Linux系统下进行视频采集方法可行,操作更简捷,效果更好.

| Abstract: | In the light of the demand for video surveillance in certain special workplaces,the method adopting scatter storage technique for video collection under embedded Linux system is studied.In view of the serious problems with the method that only uses V4L to carry out video collection under Linux system currently,the plan adopting V4L and SDL at the same time for video collection is proposed.Great importance has been attached to the solutions to such problems as real time display,access to time message and event handling,which are either hard to realize or too complicated when only V4L is used.The experimental result shows that the method adopting V4L and SDL simultaneously for video collection under Linux system is feasible,which features easy operation and better effect. |
