| 摘 要： | 克服了传统的立体摄像机标定要求在摄像机前精确地配置标定物,过程繁复,户外实现较困难的弱点,提出一种改进标定方法,通过双目匹配点,线性地求解本质矩阵,快速找出摄像机的相对位置关系。实验表明,其精度与传统的方法相当,且优于其他的快速标定方法,可广泛应用于各种户外场合。

| Abstract: | Most traditional approaches of stereo camera calibration often require expensive calibration apparatuses and elaborate setups,which limits their practicability in many out-door applications.The paper proposes a more flexible method to overcome this drawback.The proposed scheme solves the essential matrix and then calculates the relative position of the two cameras.Equation of the essential matrix is formed by finding matched points in the image-pair and solved linearly.Experiments show that the calibration results of the proposed method are better than that obtained by other fast calibration methods and can be compared with the traditional ones. |
