| 摘 要： | 建立了摄像机的径向畸变模型，采用“两步法”标定技术分解了摄像机的内外参数，将有效焦距、畸变系数、不确定因子统一于线性方程组中。使算法简便、快速、准确。通过试验比较了线性模型和畸变模型在三维重建中的误差。 |

| Abstract: | A distortion model is set up in this paper. The camera exte rn al position is decomposed by the two-stage technique. And the effective focal length, distortional coefficients and uncertain parameters are unified in a line ar functions group, which makes the algorithm simple, efficient and accurate. Th en, the errors in 3D reconstruction of linear model and distortion model are com pared through experiment. |
| Keywords: | Camera calibration Distortion model 3D reconstruction |
