摘要
研究了一种多摄像机的视野(Field of View,FOV)分界线恢复方法,利用Harris角点检测和单应矩阵的方法完成摄像机视野分界线恢复。用Harris角点检测算法提取图像中角点特征;在有重叠区域图像间进行特征点匹配,再根据匹配点计算图像间的单应矩阵;最后由图像的边界点及图像间的单应矩阵计算摄像机的FOV分界线。该方法能准确恢复摄像机的视野分界线,具有准确性和鲁棒性。
In this paper, a kind of method about restoring multi-camera＇ field of view line is researched. Harris corner detection and homograph method should be done to restore the field of view line between the cameras. First, it extracts corner features in the image using Harris corner detection algorithm. Next the feature point matching is performed between the images＇ overlap region. Then the homograph is computed according to matching points between images. Finally the FOV lines are restored by the image boundary points and images＇ homograph. This method can restore the camerag field of view line, with accuracy and robustness.
