| Abstract(E) | A novel road surface recognition method using an optical spatial filter is proposed. The optical system of a non-contact ground speed sensor with the spatial filter was adopted for the recognition. The road surfaces such as gravel, asphalt and snow were experimentally discriminated with a spatial frequency spectrum and intensity of regularly reflected light from the surface. Accordingly, the optical sensor which can detect both ground speed and a kind of road surface should be realized by means of the proposed method. |
