| 摘 要： | 为了去除高速公路监控视频中自身位置不稳定的事物给全局运动矢量估计带来误差,先通过Canny算子检测图像中的直线,并根据车道边界的特征筛选出道路边界,确定道路区域。再检测道路区域内的Harris角点信息,并与背景图中道路区域内的角点位置进行匹配,从而得到全局运动矢量,并计算出稳定的图像。实验表明,该算法能够满足高速公路场景下的稳像需求。

| Abstract: | In order to remove the estimation error of global motion vector caused by precarious locations in the supervising system of expressway,firstly,this paper detects the lines in image by Canny operator,and then chooses the road boundaries to determine road region according to the characteristics of driveway boundary.Secondly,detects Harris corners in the road region gotten,gets global motion vector by matching them with all corners in the road region of background image,and then calculates the stable image.Exp... |
