从系统工程和信息论的角度提出了对铁路工程地质信息的理解和分析。用部分研究项目的卫星遥感图像进行断裂、褶皱、岩性等信息模型描述和处理效果的对比。认为:采用功能组合的图像处理方法是萃取信息的有效方法;多个处理功能实施时,处理功能必须有序的使用;在增强提取岩性信息时,采用对光谱维的幅度参数图像进行KL压缩,选择压缩后的前三个波段合成彩色图像,具有较好的效果。从色度学和视觉响应特性的匹配关系,提出假彩色图像波段赋色,应当按照波段信息量从主到次的顺序与蓝、红、绿色别对应。 更多还原

【Abstract】 The railway engineering geology information is analyzed from a point of system engineering and information theory. The contrast of the model description and processing effect for fault, fold and rock characteristics base on some satellite remote sensing images processing project was studied. It shows that the picture processing method with combined function is an effective method to extract information. When many processing functions are put into effect, it must be used orderly.
