In this paper we propose a snow sensor that detects presence of snow on road surface. Automatic threshold selection is one of the statistical image processing techniques and is effective way to divide image into some regions that have common properties. Using this method, we can detect snow from images containing pavement marking such as center line under various road conditions. Furthermore, we install the sensor on actual road and control a snow melting system. It is confirmed that the sensor works appropriately and reduces operating time of the snow melting system compared with the conventional snowfall sensor.
