摘　　要：传统的视频采集使用连续录制的方式,一方面对存储需求较大,另一方面造成视频检索困难;针对这一问题,提出并实现了一种基于传感器驱动的视频采集和处理系统;系统以震动传感器和人体红外传感器作为触发器,实现对视频采集设备的驱动,并将获取的双路视频图像采用PIP技术进行处理;实验证明,这样做不仅能有针对性地获取视频信息,提高视频信息的可用性,而且可以扩大视频信息采集范围,节省存储空间。Traditional video acquisition using continuous recording way,on the one hand,it increases demand for storage,on the other hand,it causes difficulty of video retrieval.In order to solve this problem,a video acquisition and processing system based on sensor driver is proposed and implemented.In this system,vibration sensor and human body infrared sensor act as a trigger to drive the video acquisition device,and the obtained two-way video images are processed by using PIP technology.Experiments show that the system not only can be targeted for video information,improving the usability of video information,but also can expand the scope of the video information collection,saving storage space.
