摘　　要：提出了一种由3幅图像间一组对应消失线进行度量重建的方法.首先利用对应的消失线和模值约束计算出无穷远平面的单应矩阵,然后根据无穷远平面的单应矩阵保持绝对二次曲线的像不动的性质,线性求解摄像机内参数,最后得到度量重建.模拟实验和真实图像实验均验证了这种度量重建方法的可行性和正确性.A technique for metric reconstruction based on one triplet of corresponding vanishing line in three images is proposed. Firstly, the infinite homography is computed by using the vanishing line correspondence and the modulus constraint. Then the camera intrinsic parameters are determined linearly by using the property that the infinite homography preserves the image of the absolute conic. Finally a metric reconstruction is obtained. Experiments with simulated data as well as with real images show that the proposed method is workable and applicable in real applications.
