Abstract
We investigate the projective properties of the feature consisting of two concentric circles. We demonstrate there exist geometric and algebraic constraints on its projection. We show how these constraints greatly simplify the recoveries of the affine and Euclidean structures of a 3D plane. As an application, we assess the performances of two camera calibration algorithms.
摘要
我们研究了由两个同心圆组成的特征的投影特性。我们证明了其投影存在几何和代数约束。我们展示了这些约束如何极大地简化三维平面仿射结构和欧几里得结构的恢复。作为一个应用，我们评估了两种相机校准算法的性能。
