摘要:
为了提高双目摄像机标定参数的精确性,以张氏标定方法为基础,首先采用Harris 算法对黑白棋盘表格进行内角点提取,其次将内角点像素点坐标精确到亚像素精度,最后利用投影线性关系求出双目摄像机的内外等参数,并与cvFindChessboardCorners()函数提取内角点标定方法进行对比,证明了该方法准确、有效,提高了黑白棋盘表格内角点检测的准确性和标定精度,可以应用于双目视觉系统中.
Abstract:
In order to improve the accuracy of binocular camera parameter calibration, on the basis of the Zhang’s calibration approach, Harris algorithm was adopted to extract angles point of the black and white chessboard.The internal angle points in pixel coordinates is made accurate to sub-pixel accuracy.Finally this paper uses the internal and external parameters of binocular camera by linear relationship .The experimental result compares with the Zhang’s calibration approach in cvFindChessboardCorners(), which show that the method is accurate, effective which improves the precision of black and white chessboard form an internal angle detection and calibration precision.The result can be applied to the binocular vision system.
