基于环形队列的视频预录方法

Video Pre-Recording Method Based on Circular Queue

针对嵌入式智能相机芯片算力有限,在同时运行不同算法检测不同事件时,算法延时导致录像不及时的问题,提出了一种基于数组的环形队列实现的预录功能。在人形检测算法上进行验证,实验结果表明,环形队列可保存事件发生前最新的视频数据,基于此种方法实现的预录功能可完整保存事件发生前后的视频内容,解决了由于算法延时造成的事件记录不完整问题,在一定程度提高了智能相机的安防性能。

Aiming at the limited computing power of embedded intelligent camera chip,when different algorithms are running at the same time to detect different events,the algorithm delay leads to the problem that the video recording is not timely,and a pre-recorded function based on array loop queue is proposed.The experimental results show that the ring queue can save the latest video data before the event,and the prerecorded function based on this method can completely save the video content before and after the event.The problem of incomplete event recording caused by algorithm delay is solved,and the security performance of intelligent camera is improved to some extent.
