摘要
通过对遥感数据生成机理的分析,得出遥感数据存在不确定性,并进一步论证了不确定性中含有模糊不确定性,这样对遥感数据的不确定性处理更加全面和合理,从而达到提高遥感数据的精度和消除遥感数据不确定性的目的。综合国内外对遥感数据模糊不确定性的处理研究,探讨了几种处理方法,发现还没有一种方法能圆满解决遥感数据的模糊不确定性。
The paper gets across analysis on creating mechanism of remote sensing data, and derives that remote sensing data existed uncertainty, and more proofed uncertainty contained fuzzy uncertainty. In this way, it is complete and reasonable in dealing with remote sensing data so as to realize the aim to improve remote sensing data precision and eliminate fuzzy uncertainty. Analyzing researches on processing remote sensing data fuzzy uncertainty at home and abroad, the authors discuss several methods, and find out that no methods can really and wholly solve remote sensing data fuzzy uncertainty at present.
