摘要
安防监控系统中常要处理YUV格式的图像数据。实时存储的单位时间内数据量大,容易丢帧。为满足实时存储的需求,设计并实现了一种基于多线程的YUV格式的图像存储软件。采用定量的缓冲区进行缓存大量实时的YUV数据,再利用多线程实现该数据的实时存储。实验结果显示以多线程实现的摄像机实时数据采集和实时数据存储是可行的,而且能够确保记录的图像数据丢帧率低、可用性高。
The image data which format is YUV is often processed in security monitoring system. Thedata of real-time storage are large and easy to lost frames. In order to meet the demand of real-timestorage, a image storage software about YUV format was designed and implemented in the paper, itadopted quantitative buffer whichmultithreading for implementing datadata collection and storage of vidiconloss rate and high usability.could cache plenty of real-time YUV data and made use of＇ s real-time storage. The experiment result showed that the real-timebased on multithreading were feasible, it was also insured low frame
