【摘要】 Harris算子是在计算机视觉领域使用非常广泛的点特征提取算子,它算法简单,而且稳定,但当在光照、震动等复杂情况下,准确率却达不到实际应用的要求。由棋盘角点周围灰度中心对称的特征,提出了一种基于Harris算子改进的棋盘角点自动提取方法。实验证明,该方法可以准确地自动提取标定点,有效地提高标定的精度。更多还原

【Abstract】 Harris corner detector is most widely used in the field of computer vision.It is simple and stable.However,when there are the defect in the light,vibration and other complex cases,the accuracy rate is not practical application requirements.Around the corner from the chessboard gray center symmetrical features,raise a based on Harris chessboard-corner automatic extraction methods.Experiments show that it is an accurately automatic extraction method to improve the accuracy of calibration effectively.更多还原
