摘要: Existing orthophoto map based on satellite photography and aerial is not precise enough for road marking. This paper proposes a new approach to high-accuracy mapping. The uses inverse perspective transformation process the image information generates fragment. offline interpolation algorithm used location information. It processes dead reckoning EKF information, result transform fragments global coordinate system. At last it wavelet divides two frequency bands weighted median deal with them separately. of experiment shows that produced this method has high accuracy.
