Abstract:
The method is based on the reconstruction unit of three views. To avoid the complex computation of trifocal tensor, a simple strategy is presented. After that, a global feature matching process is taken. And a parallel hierarchical method to combine correspondences is used. For a sequence of size n, the traditional method needs (n-1) combinations and (n-1) layers, while the method presented needs (n-2) combinations and lb(n-1) layers, in each layer the combinations are parallel.
Key words:
image sequence,
projective reconstruction,
multi-view geometry,
fundamental matrix,

摘要: 可并行迭代式重建策略以三视图为重建单元,为避免求解三焦张量而提出一种简单的实现策略,并对三视图进行全局的特征点匹配。给出可并行的分层对应点合并策略。对长度为n的序列,传统迭代方法需要进行(n-1)次重建单元合并,且重建层数为(n-1),而对可并行迭代策略需要进行(n-2)次单元合并,重建层数为lb(n-1),且每一层的单元合并完全可并行。
