Multidisciplinary Analysis for Feature Information Extraction of Remote Sensing
|
Abstract:
According to the spectral characteristics of different geobodies, and using principal component analysis, information multiplex and multidisciplinary analysis method, a good result of mineralized information extraction was given in this paper, with FIMS flight strip in Tie-muerte of North Xinjiang.The yellow abnormal color tone was show en in the mineralized feature information of FIMS flight strip of the region in image processing result. It reflected on mineralized feature with lower content of silica and higher f erri-ferrous content in polymetalic mineralization belt. Yellow abnormal color tone in form of lumps showed the distribution of gasson, magnetite and skarn on exposing surface. According to the field examination, the distribution section of yellow color tone is in agreement with the mineralized area on the spot surface.There are four steps of multidisciplinary analysis for extracting the feature information of remote sensing, which are independent of each other and also related to each other. The four steps include: The analysis of essential feature information, image processing, verification analysis and mechanism explaination. In fact, only by multidisciplinary analysis, could the inherent law of feature information be revealed and the feature information extracted be made into a good practical value one.
