卫星图像实时接收及回显技术研发

为了快捷而方便地实时接收卫星图像并进行质量分析,在运行控制系统的图像子系统中开发了卫星图像实时接收及回显主控接口软件。该软件是在SGI工作站上以UNIX操作系统为平台,运用X窗口系统、MOTIF窗口管理器和SGI公司的IRISGL的图形技术,采用C语言编写的。通过控制界面和控制选项实时接收卫星图像并将从磁盘或磁带上传输过来的图像资料进行各种回放显示、加网格、黑体定标、图像定位、提取周时间表等显示处理并进行质量分析。该软件已运用在气象卫星资料的实时处理中。

Development of Real-time Reception and Display Techniques for Satellite Images

In order to quickly and conveniently receive and analyze the satellite images in real time,the master interface software for satellite images real-time reception and analyses was developed in image subsystem of running control system.The software was developed by UNIX platform,X-Window,Motif,IRIS GL and C program on SGI workstation.The satellite images were received through control interface and options.Moreover the images transmitted through disks or tapes were displayed,processed and qualitatively analyzed by options such as "replay","grid","line","samelola" and "display-manam".And the software has been applied in the actual processing of meteorological satellite data.
