摘要 基于单幅图像的摄像机姿态问题是计算机视觉领域中的核心问题之一.在已有的姿态估计方法中,通常要求已知空间点或线的精确位置,本文借助于旋转体自身的对称特性,避开了这一难题,给出了一种利用旋转体来估计摄像机的姿态的新算法,并通过模拟实验和真实实验,验证了该方法的可行性和有效性.此方法是一种比较灵活方便的姿态估计方法. Camera pose estimation from a single image is one of the key issues in computer vi sion. Most existing approaches need accurate space information. A new method is proposed based on the surface of revolution, taking advantage of its special attribute of symmetry, thus avoiding the knotty problem. Both synthetic and real data show that this technique is feasible and flexible.
