【摘要】 提出了一种基于扩展摄像机成像模型的自标定方法,将采用不同视点成像的观念转换为不同方向透视投影下分析,得到在一幅图像中同时建立三对不同方向的空间面与图像面的单应关系,进而建立不同面的圆环点绝对二次方程,实现单幅图像标定。采用长方体进行实验,模拟实验和真实图像实验均验证了这种思维方法的可行性和正确性。更多还原

【Abstract】 This paper proposed a technique for self-calibration based on extended camera model.Changed a conception of thinking from different views photography to different direction perspective projection.Thus,it could obtian three different homography between space plane and image plane from one image simultaneously,and set up the absolute conic equation of circular points within their plane.So a single image completed the process of calibration.Took regular solid to vertify the idea and thinking way.Experiments with simulated data as well as with real images show that the proposed method is workable,and applicable in real applications.更多还原
