Estimating the pose of objects with circle feature from images is a basic and important question in computer vision
community. This paper is focused on the ambiguity problem in pose estimation of circle feature, and a new method is proposed based
on the concentric circle constraint. The pose of a single circle feature, in general, can be determined from its projection in the image
plane with a pre-calibrated camera. However, there are generally two possible sets of pose parameters. By introducing the concentric
circle constraint, interference from the false solution can be excluded. On the basis of element at infinity in projective geometry and
the Euclidean distance invariant, cases that concentric circles are coplanar and non-coplanar are discussed respectively. Experiments
on these two cases are performed to validate the proposed method
