This paper proposes an object detection method using characteristics of spectral reflectance in mid- infrared region. Retroreflective traffic signs are irradiated with infrared light and the reflected light from the traffic signs is taken with an infrared camera. Infrared lights with wavelength of around 1400nm and 1150nm are used, since solar lights do not contain these wavelengths and the detection of traffic signs can be realized without the effect of the sun. The effectiveness of the proposed method is verified by experiments.
