摘    要:利用2视图进行景物的3维重构中,基本矩阵的估计是一个非常重要的问题。目前无论是线性算法还是非线性算法,在估计基本矩阵时都不太理想。这里采用图像的Harries角点作为端点,经过基于小波变换的子线段匹配方法获得高精度的匹配点对;在此基础上,进一步采用Hartley提出的改进八点算法获得了高精度的基本矩阵。通过真实图像的对比实验证明,该方法能有效地提高景物3维重构中基本矩阵估计精度。

关 键 词:计算机视觉  基本矩阵  鲁棒估计  点特征提取  子线段匹配

Abstract:It's an important problem to estimate the fundamental matrix in two images for 3D construction.Now,it's not perfect to do this both with the liner and non-liner algorithm.The Harris characteristic points were used as extremity to get the high-precision matching points by the way of matching sub-line segment which based on wavelet transformation,and then,normalized eight-point algorithm proposed by Hartley was used to estimate the high-precision fundamental matrix.The true image experiments showed that this ...
Keywords:computer vision  fundamental matrix  robust estimation  extracting feature points  sub-line segment match
