摘要
随着遥测领域对视频图像数据需求的快速增长,高速视频与多图像流的实时处理成为关键技术挑战。基于Windows呈现基础(Windows Presentation Foundation,WPF)框架,采用模块化架构与多线程动态分配机制,设计了遥测多路视频图像解析软件。通过地面站接收飞行器遥测信号,利用自适应线程池实现数据解析与影像流解码的并行处理,有效解决了传统单线程模式在处理高速视频时出现的卡顿和绿屏问题。集成了多源图像同步显示与动态合成功能,支持靶场飞行试验中实时性、高帧率及高分辨率视频流的稳定呈现,并为遥测数据的事后分析提供了可视化工具。实际飞行试验表明,该软件在靶场应用中具备优异的实时性、高帧率与高分辨率表现,可以满足工程实践要求。
With the rapid growth of demand for video image data in the telemetry field,real-time processing of highspeed videos and multi-image streams has become a key technical challenge.Based on the Windows Presentation Foundation(WPF)framework,a telemetry multi-channel video image parsing software was designed using a modular architecture and a multi-thread dynamic allocation mechanism.By receiving aircraft telemetry signals through a ground station and utilizing an adaptive thread pool to achieve parallel processing of data parsing and image stream decoding,this software effectively solves the stuttering and green screen issues that occur when traditional single-thread modes process highspeed videos.It integrates multi-source image synchronous display and dynamic synthesis functions,supports the stable presentation of real-time,high-frame-rate,and high-resolution video streams in range flight tests,and provides a visualization tool for the post-analysis of telemetry data.Actual flight tests show that the software exhibits excellent real-time performance,high frame rate,and high-resolution performance in range applications,which can meet the requirements of engineering practice.
