摘　　要：针对现有井下救援视频信号差,易受环境干扰,系统集成度低,不能实时显示现场救援信息等问题,提出了一种适用于井下救援通信的嵌入式视频信号处理系统。系统主要包括井下视频采集端和井上救援指挥端。井下视频采集端系统采用Linux作为软件开发平台,利用S3C6410自带的编码器MFC对视频数据进行H.264标准压缩编码;井上救援指挥端系统在VS2005开发环境下实现视频解码,网络传输和应用程序的开发,并针对矿山救援环境特点优化开源H.264解码算法。该系统完成了救援现场视频处理,提高了设备集成度和视频画面清新度,实现了井下救援的可视化。Aim at problems like poor signal, vulnerable to environmental interference, low system integration degree and cannot display site rescue information on the spot exist in current underground res- cue video, a kind of embedded video signal processing system suitable for underground rescue communi- cation was put forward. The system mainly consists of two parts ： the underground video capture terminal and surface rescue command terminal. H. 264 standard compression done on video data by using the own encoder MFC of $3C6410 and adopt Linux as software develop platform in the underground video capture terminal system. On the other hand, video decoding, network transmission and development of applica- tion program realized for surface rescue command terminal system in VS2005 development environment, and according to the characteristics of the mine rescue environment, an optimization about the open source for H. 264 decoding algorithm is made. This system has accomplished rescue site video process- ing, improved the equipment integration level and video picture clarity, and realized the visualization of underground rescue.
