Angular spectral response from covered asphalt
2007 (English)In: Applied Optics, ISSN 1559-128X, E-ISSN 2155-3165, Vol. 46, no 20, 4277-4288 p.Article in journal (Refereed) Published
By measuring the spectral reflection from the four different road conditions dry, wet, icy, and snowy asphalt, a method of classification for the different surfaces -- using two and three wavelengths -- is developed. The method is tested against measurements to ascertain the probability of wrong classification between the surfaces. From the angular spectral response, the fact that asphalt and snow are diffuse reflectors and water and ice are reflective are confirmed.
