研究基于图像序列的分层重构,包括射影重构和欧氏重构,主要介绍在射影重构过程中如果存在遮挡情况所采取的算法,并简单介绍了欧氏重构。存在遮挡时,选取序列中的三幅图进行处理,采用因式分解的方法获得结构模型,并且从获得的结构模型去检验被遮挡部分的溢出值,从而提取出有效值。实验证明算法的重建效果好。
This article does some research about the algorithm of hierarchical reconstruction. Hierarchical reconstruciton con- cludes projective reconstruction and euclid reconstruction. This article introduces projective reconstruction with occlusion and euclid reconstruction. When there is occlusion,it chose three of the images' sequence with factorization to get the structure. Then it can use this structure to do the validity check for outliers. In experiment, the result of this method is validity.
