热敏拷贝遥感图像制图是计算机控制下图像数据直接输出至热敏拷贝机成图的技术。其速度高、成本低、灵活性好。同常规遥感图像制作技术相比,自动化程度高,工序简单。作地质解译效果良好。遥感图像数据经分块拷贝、合并镶嵌,可制作成大幅面的彩色合成图像,是微机遥感图像处理系统中理想的输出设备。本系统引进的COLORVIEW热敏拷贝机,联接在Oliveti 486微机上。由磁带机将TM磁带数据读入主机,经过各种处理,最后三个通道数据以红、绿、兰合成彩色的方法由COLORVIEW热敏拷贝机输出。制作了1/10万和1/5万的大幅面TM彩色合成图像。热敏拷贝机是以减色法替代红、绿、兰加色法合成为真彩色。其色彩是由黄、品红、青三色染料依据三个通道灰度值的大小通过抖动矩阵拷贝在白纸上。在遥感图像的加色法合成中,以红、绿、兰三原
Thermal copy remote sensing image mapping is a computer-controlled image data output directly to the thermal copy machine mapping technology. Its high speed, low cost, good flexibility. Compared with the conventional remote sensing image production technology, a high degree of automation, the process is simple. Geological interpretation of good results. Remote sensing image data by the block copy, the merger mosaic, can be made into a large format color composite images, computer remote sensing image processing system is the ideal output device. The system introduced COLORVIEW thermal copy machine, connected to the Oliveti 486 microcomputer. By the tape drive to read the TM tape data into the host, after a variety of processing, the last three channels of data to red, green and blue color synthesis methods COLORVIEW thermal copy machine output. Produced 1/10000 and 1/5 million large-format TM color composite images. Thermal copy machine is subtractive method to replace the red, green, blue plus color synthesis for true color. The color is yellow, magenta, cyan dye according to the size of the three channels of gray-scale dither matrix copy on white paper. In remote sensing image additive color synthesis, with red, green, blue three original
