根据机载扫描仪的特点和遥感用户的要求,精心研制了在脱机状态下运行的CCT格式器。其主要功能:(1)将模拟磁带上的多光谱遥感信息数字化,制成便于计算机处理的通用格式化产品——计算机兼容磁带(CCT);(2)读出CCT上的数据,进行图像的快速显示或硬拷贝;(3)对指定的子区目标,进行快速查找与定位。 本文详细论述CCT格式器硬件和软件设计特点,给出磁带数据格式,介绍一些使用情况。该格式器不仅作为机载扫描仪的主要配套设备之一,而且也适合那些需要处理大量磁带数据的图像处理系统。
According to the characteristics of the airborne scanner and the requirements of the users of remote sensing, the CCT formatter running offline is carefully developed. Its main functions are as follows: (1) Digitizing the multi-spectral remote sensing information on the analog tape to make CCT (Computer Compatible Cartridge) which is a common format product for computer processing; (2) Reading out the data on the CCT for image Fast display or hard copy; (3) the designated sub-area target, for quick search and positioning. This article discusses in detail CCT formatter hardware and software design features, given the tape data format, introduces some usage. This formatter not only serves as one of the main ancillary equipment for on-board scanners, but also for those image processing systems that need to handle large amounts of tape data.
