| 摘 要： | 提出了一种考虑径向畸变的摄像机线性标定方法。采用一个方格图样模板进行标定,先利用改进的Harris算子精确提取角点的亚象素坐标,通过预标定获得主点坐标;然后在考虑摄像机径向畸变的情况下建立摄像机模型,并求解摄像机内外参数。实验及误差分析表明:该标定方法具有较高的精度和较好的实时性。

| Abstract: | A new linear approach with radial distortion model for camera calibration is presented. Firstly,the improved Harris detector is applied to obtain the sub-pixel coordinates of the corners.Then a camera model with radial distortion is established to calculate the intrinsic and extrinsic parameters of the camera.The experimental results demonstrate its high accuracy and efficiency. |
