【摘要】 相机标定是计算机视觉领域中从二维图像获取三维空间信息必不可少的步骤,传统的标定方法利用3个正交方向的消失点来进行标定,实际场景中不容易同时得到三个正交的消失点。本文在多幅图像中利用消失点不变性约束对两个相互正交方向的消失点来对相机进行自标定,实验结果验证了本文算法的有效性。更多还原

【Abstract】 Camera self-calibration is key issues in computer vision.The conventional algorithm make use of three orthogonal vanishing points to calibrate camara,but it is difficulty to obtain three orthogonal vanishing points in the real-world scene.In this paper am algorithm ios designed to calibrates camera parameters only using two orthogonal vanishing points by the vanishing points invariance constraints in a number of images,the experimental results confirm the efficiency of our algorithm.更多还原
