Reconstruction of Implicit Surfaces from Uncalibrated Camera Image Sequences

  • 摘要: 为了提高未标定图像序列三维重建得到的几何模型的质量,提出特征点检测算法,以得到更多的匹配点.其主要思想是在首帧图像指定密集的网格,在网格点附近确定最容易跟踪的特征点,利用迭代方法得到子像素精度的特征点坐标,然后用稀疏特征集的金字塔Lucas-Kanade光流跟踪算法跟踪这些特征点,再用自标定算法,重建出相对均匀和稠密的三维点云,最后利用基于径向基函数(RBF)的隐式曲面重建算法,生成目标的表面模型.多个图像序列的重建结果表明,本方法对纹理丰富的场景能够获得较好的重建结果.
