| 中文摘要: |
| 提出了采用成直角关系的3点作为标定装置来求解数码相机的外部参数.该方法是利用三角形标定装置的成像过程,建立一个与标定装置相似的三角形,再利用直角三角形两直角边正交的特点,建立数码机外部参数的数学模型.推导了数码相机拍摄图像时的外部参数矩阵中各参变量的计算公式.实验证明了这种方法的可行性和实用性. |
| 英文摘要: |
| A method is brought forward that exterior parameters of digital camera are calibrated with calibration apparatus of right-angle three points in this paper.A triangle similar to calibration apparatus is built with imaging process of the apparatus.A mathematical model is built on digital camera exterior parameters in which characteristic of right-angle triangle is used. Calculation formulas of all exterior parameters of the digital camera imaging are derived.Experiment has proved that the method is feasible and usable. |
