摘要
遥测系统在传输图像数据时,通常要求图像遥测单元在尽量小的空间中较多地采集和传输图像信息,以提高图像质量和试验效率,减少系统研制成本。遥测图像压缩系统通过采用大规模FPGA和专用图像压缩芯片方法,在紧凑空间内,实现了遥测图像压缩系统的全部功能,节省了传输带宽,提高了系统的整体性能体积比。该遥测图像压缩系统已应用于具体试验,试验结果证明,遥测图像系统的设计可以满足系统的使用要求。
Telemetry systems usually require that the telemetry units should,in a smaller space,acquire and transfer more image information,and thus to improve the test efficiency and reduce system development costs.The remote sensing image compression system adopts large-scale FPGA and special image compression chip,thus to improve its overall performance and achieve its full functionality in a compact space.The telemetry sensing image compression system is applied to the specific test,and the results show that the design of remote sensing image unit could meet the system requirements.
