| Abstract(in English) | Recently, Virtual Earth, Google Earth, or Map Cube provide a virtual city modeled from real outdoor environment, and they also provide a service to embed other virtual objects into the virtual space. For the first step for analyzing such complex outdoor scene, we show some results of analyzing the skylight, which dominates the half of the outdoor scene. The sunlight is unpolarized, and the sky becomes polarized when the sunlight is reflected at the aerosol. We provide some experimental results of detecting the sun orientation under clear sky and cloudy sky, using linear polarizer and fisheye lens. |
