高速数字图像记录系统的实现
Development on high-speed digital image acquisition
摘要
在弹道测量中,高速数字图像数据的获取有重要意义.在实现记录功能的基础上,论述实现记录系统的实时性优化问题.对Windows的部分性能做出了调整,解决了Windows的非实时性对记录系统的影响.提出了记录系统的线程池模型,提高了系统对实时性记录任务的吞吐率.制定记录系统的丢帧检测方案,测试结果表明:整个系统可完成50 MB/s的高速图像记录任务,工作稳定正常.
Abstract
High-speed digital video acquisition is important for the image inspection in ballistic trajectory.How to optimize real-time characteristic of recording system is discussed. Contraposed windows operation system′s non-real-time characteristic, several methods are proposed to reduce non-real-time characteristic of operation system. Thread pool model of system is proposed to enhance throughput ratio of recording task.Scheme of losing image ratio detection is establised. Testing result shows that grabbing velocity breaks through 50 MBps and the whole system works steadily.
