| 摘 要： | 提出了一种全自动、基于纯平液晶显示器（LCD）面格网、非参数畸变差和有限元内插模型的相机标定方法。由于相机内参数自身，以及内参数与绕LCD屏幕垂轴旋转的旋转角之间严重相关，特别引入了另外两类条件方程，使得参数之间的相关性得到削弱。实验证明了该方法的可行性，并且其精度高于一般的基于参数畸变差的标定方法。

| Abstract: | A new camera calibration method is presented based on completely flat liquid crystal display (LCD) and the interpolation model of digital elevation model (DEM) by finite elements, which belongs to non-parametric distortion calibration model. Firstly, the proposed calibration method is presented detailedly. And then, two other kinds of conditional equations are imported after correlativity analysis. A simple and automatic calibration algorithm is designed. Good results and comparisons with the method of normal parametric distortion model show that its accuracy is better than that of the latter. |
