We propose a method of judging fog density using in-vehicle camera and millimeter-wave(mm-W) radar for driving support in foggy conditions. Behind this, there is the growing interest in driving support technologies of recent years. It is known that accident rates in bad weather conditions are about 17 times higher than that in fair ones. Especially under foggy conditions, drivers are not aware, though fog negatively in°uences human percep-tion. It is the cause of making dangerous situations. From this, a driving support system, such as danger alerts or automatic lighting of fog lamps is expected. Considering these problems, a method of judging fog density by using in-vehicle camera and mm-W radar is proposed in this report. To evaluate fog density, the scattered coe±cient in Koschmieder's model is used. This can be calculated from the change of the variance of brightness between the captured vehicle image and a vehicle image captured in a fair condition and the distance to the vehicle. The proposed method classi¯es the image into three classes of fog density from calculated scattered coe±cient. To evaluate the performance of the proposed method, we compare the judgments by the human subjects and the proposed method. From this, a concordance rate acheved 84%. |
