摘要
目前所采用的视频处理软件不能满足试飞工程师试飞数据分析处理的专用需求,面临现有商业软件所存在的众多局限性,采用解码库和时间戳同步等方法通过VC编程解决了多种视频音频格式解码、多路视频时间精确同步等关键技术。经过试飞工程师实际使用验证表明,该软件满足试飞视频数据分析处理所需的时间同步、精确定位等专用需求,本文详细介绍了该软件的结构和各功能模块,并讨论了软件的具体实现、技术创新点及软件实现的关键技术。
Because the video processing software can not meet the special needs for data analysis and processing of the flight test engineers due to many limitations existing in the available commercial softwares, decoding libraries and timestamp synchronization are adopted in this paper to realize the key technologies of various video and audio format decodings, and multi-channel video time precise synchronization through VC programming. The actual application of flight test engineers show that the the software can meet the time synchronization, precise positioning and other special needs required for data analysis and processing of the test flight video synchronization. The structure and function modules of the software are described in detail, and the key technologies of specific implementation method, technology innovation and software design are discussed in this paper.
