【摘要】 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。更多还原

【Abstract】 The off-line working CCT formatter for the airborne scanner was successfully developed according to the characteristics of the airbone scanner and the requirements of the remote sensing users. Its principal functions are:(1) To transform the multispectral remote sensing information to computer compatible tape (CCT) from analogue high density tape.(2) To read out CCT data for quickly displaying or hardcopy of the image.(3) Rapidly to check up and locate given target in the subarea.This paper describes the design features of the CCT formatter hardware and software in detail. The CCT data format and some results of application are shown. The CCT formatter is not only one of the main fittings of the scanner, but also suitable for those digital image processing systems which deals with processing a large number of CCT data.更多还原
