| 摘 要： | 图像采集系统负责监控和记录运载器上多个重要点位的视频信息。文中介绍了一种基于网络架构的箭载通用图像采集系统,负责采集高清图像并无损存储在图像压缩器内,将高清图像压缩后经遥测传输至地面,由于带宽有限,可实时切换下传的图像信息,同时支持通过网络实时访问箭上图像信息和事后图像数据回读功能,为评估箭上的工作状态或分析故障提供了保障。

| Abstract: | The image acquisition system is responsible for monitoring and recording the video information of several important points on the carrier.A general image acquisition system on board the rocket based on network architecture is introduced,which is responsible for collecting high-definition images and storing them losslessly in an image compressor.The high-definition images are compressed and transmitted to the ground through telemetry.Due to the limited bandwidth,the image information transmitted down can be switched in real time.At the same time,real-time access to image information on the rocket is supported through the network and post image data retrieval function,and guarantee for evaluating the working state of the arrow or analyzing the fault is provided. |
