| Abstract(in English) | This paper proposes an accurate restoration method of in-vehicle camera images in foggy conditions based on Kalman filter. Utilizing a cross ratio, the proposed method estimates a vanishing point from the target images, and calculates parameters of a fog deterioration model. Further, this model is introduced into the observation model of the Kalman filter. In addition, a new model, which estimates intensities between successive frames by using motion vector and compensate their errors, is also introduced into the state machine model. Consequently, since the proposed method achieves the restoration using the correlation between the successive frames, the accurate performance can be realized. |
