Study of Defog Technology Based on Scattering Model in Assistant Driving System
Hongjun Liu, Yan Zhou, Xinwei Wang · 2009
This paper firstly analyzes a typical defog algorithm. Directly towards assistant driving system, monocular camera machine vision and atmosphere scattering model are combined to construct the scene depth map by linear imaging model. At last, the image was restored by atmosphere scattering model. With RETINEX algorithm, this method has a better effect in different distance: the error of depth map increases along distance increasing; two factors on the algorithm precision: the installing height and pitching angle of camera. Finally, point out that next stage we estimate the error coursed by extrinsic parameters by experimentation.
