【摘要】:正目前,巖石礦物光譜識(shí)別利用的光譜吸收特征主要包括波譜曲線的譜帶寬度、形態(tài)、深度、位置及光譜的相關(guān)系數(shù)等相似性度量(周強(qiáng)等,2005)。研究表明,在不同影響因素下礦物光譜特征參量的穩(wěn)定性對(duì)蝕變信息提取影響很大。因此,在蝕變信息提取中采用比較穩(wěn)定的光譜參量是研究的一個(gè)重點(diǎn)(王潤(rùn)生等,1999;杜培軍等,2006;張宗貴,2004;杜培軍等,2003)。在礦物光譜曲線的諸多特征中,峰谷位置是最穩(wěn)定、最主要的特征。因此,
[Abstract]:At present, the spectral absorption characteristics used in the spectral recognition of rock minerals mainly include the spectral band width, shape, depth, position and correlation coefficient of the spectral curve (Zhou Qiang et al. 2005). The results show that the stability of mineral spectral characteristic parameters has great influence on the extraction of alteration information under different influence factors. Therefore, the use of relatively stable spectral parameters in the extraction of alteration information is one of the key points of the study (Wang Runsheng et al. 1999; du Peijun et al. 2006; Zhang Zongguirong 2004; du Peijun et al. 2003). Among the characteristics of mineral spectral curves, the peak and valley position is the most stable and main feature. Therefore,
