摘要：

This paper established an eccentric error mathematics model based on analysis of the effect of concentric circle eccentricity error caused by perspective projection, and put forward a high-precision camera calibration method based on concentric eccentric error compensation iteration. The method used optimization algorithm based on geometric constraint to constantly update the coordinates of the center projection of concentric circles, so as to achieve high precision camera calibration. Experiments and simulations verify the effectiveness of the proposed method in visual applications. The results show that the proposed method can provide higher precision calibration results for computer vision and three-dimensional reconstruction tasks compared with traditional methods.
