| 摘 要： | 研究了基于直线特征的非量测相机几何标定方法,依据中心投影影像的几何特性建立了基于直线特征的相机内参数标定模型,并推导了其线性化公式。与常规基于控制点的空间后方交会和几何检校的实验结果对比表明,该方法可以达到与传统方法同等的定位精度,且回避了常规方法物像必须严格对应的问题,为缺少控制点情况下的几何标定提供了另一个可选方案。

| Abstract: | The characteristics of the camera calibration method based on linear features was introduced in this pa-per.According to the geometric characteristics of the central projection image the model of camera calibration pa-rameters based on linear features was established. Compared the results with that of the conventional one based on control points the method can achieve equivalent positioning accuracy and avoid the problem that the object side and the image side must strictly correspond to each other which provides another option for the case of lack of con-trol points. |
