千兆级视频流实时处理关键技术研究

Study on Key Technologies of Real-time Processing of Gigabit-level Video Stream

机载遥感系统图像具有数据量巨大、传输速率高、存储时间长等特点。为保证数据传输稳定,解决图像数据传输过程中的丢帧问题,针对目前常见的各种图像数据存储和显示的软硬件实现手段进行分析比较,设计了一种稳定的基于GigEVision协议的千兆级视频流实时处理系统。重点介绍了系统的软硬件构架和视频处理模块StreamPix的开发途径。实验表明该系统能对视频图像进行实时显示和存储,丢帧率为零,图像回放清晰,效果优良。

Based on the airborne monitoring systems having the following features,huge amounts of image data,high transfer rate,long storage time and so on,in order to ensure stable data transmission and solve the problem of the frames dropping during the transmission process,a stable system based on GigE Vision protocol is designedto real-time process gigabit-level video stream,by anglicizing and comparing the software and software and hardware architecture implementation of the system.The system hardware selection and the module＇s design of StreamPix for the video process are introduced.Experiments show that the system can display and store the high-definition images real-time.Leakage frame rate is 0.The playback of video is clear and fluent.
