岩石表面的BRDF特征模型研究
Study on BRDF Feature Model of Rock Surface
摘要
Abstract
The multi-angle reflectance spectrum of rock surface in 2π space was studied in this paper. By studying the BRDF spectral characteristics of more than 10 kindsof rock in 2π space, we summed up the multi-angle rock surface bidirectional reflectance distribution function(BRDF) feature model. Four factors' data: reflectance spectrum, light incidence angle, detection angle, and azimuth angle were measured for these 10 kinds of rock in the experiment. The results showed that the impact of the incident angle of light was most important in the experiment. The reflection spectra of rock, varies significantly with the angle change of incidence of the light. Secondly, under the same detection angle, space horizontal azimuth impacts polarization characteristics on spectrum, and these spectra performed the elliptical distribution. We will be able to fully describe the reflection spectrum characteristics of rock under different incident angles in 2π space, and then determine the BRDF model, only using or measuring some of the key data of the direction of e, p value. If the BRDF reflection by the multi-angle feature model is established, we can use it to correct the existing geological remote sensing spectral image.关键词
