| 摘 要： | 为使相机检校过程简单化,本文提出一种分步骤的相机检校方法。即基于延伸焦点的原理标定相机的主点;基于直线求解影像几何畸变系数;对影像进行畸变改正后,利用简单的三角形相似原理,求解相机的主距。 |
| 关 键 词： | 数码相机 内方位元素 畸变系数 |

| Abstract: | In order to simplify camera calibration procedure,a new method is proposed to estimate both the interior orientation parameters and lens distortion step by step.The principle point is calibrated on the basis of the focus of expansion(FOE) priciple at first.Vertical lines are used for determining lens distortion.After correcting lens distortion of images,principle focus length is calculated using the similar triangles theorem. |
| Keywords: | digital camera interior orientation parameters distortion parameters |
