摘要：

针对车载相机在线标定问题，尤其是外参数标定方面，文中提出了一种基于车道线的在线标定方法，首先通过分析相机外参数与消失点、拍摄倾角之间的关系，将外参数的计算方法进行化简，并在已知相机高度的条件下，通过寻找场景中两组相互垂直的平行线，获取相关信息进行参数标定。实验结果表明，文中所提出方法简便可行，且具有一定的实用价值。

Abstract:

A new method based on lane line for self calibration of vehicle camera, especially the external parameter calibration, is proposed. By using the relationship between the external parameters of the camera and the vanishing point and the shooting angle, the calculation method of the external parameters is simplified. With the height of the camera given, the parameters can be calibrated by looking for two of the parallel line information. Experiments show that the proposed algorithm is feasible and of practical value.

Key words: vehicle camera, lane line, double parallel lines calibration, external parameter
