| 摘要: |
| 提出了一种基于圆环点的新的摄像机自标定方法.该方法仅要求摄像机在3个(或3个以上)不同方位摄取一个含有若干条直径的圆的图像,即可线性求解全部摄像机内参数.该方法原理简单,完全摆脱了匹配问题,也无须知道任何物理度量.整个定标过程不需要人的干预,可以自动进行,非常适合非视觉专业人员使用.模拟和真实图像实验表明,该方法精确度较高,鲁棒性较强,有一定的实用性. |

| Abstract: |
| A new easy technique for calibrating a camera based on circular points is proposed. The proposed technique only requires the camera to observe a newly designed planar calibration pattern (referred to as the model plane hereinafter) which includes a circle and a pencil of lines passing through the circle抯 center, at a few (at least three) different unknown orientations, then all the five intrinsic parameters can be determined linearly. The main point of the proposed technique is that it does not need know metric measurement on the model plane and the corres pondences between points on the model plane and image one,hence it can be done fully automatically.The proposed technique is particularly use for those people who are not familiar with computer vision.Experiments with simulated datawell as well as with real images shoe that the new technique is robust and accurate. |
