Abstract (in Japanese) (See Japanese page) 
(in English) This article proposes a parallelization method for multi-view stereo 3D shape reconstruction using a PC cluster. The proposed method divides the subject 3D space into several domains by planes passing through a virtual view point, and assigns the process for each divided domain to a PE (Processing Element) individually. This process assignment approach can reduce the amount of inter-PE communication. In addition to this, the proposed method balances the loads on the PEs dynamically for efficient parallelization. The experimental results show that the proposed method can reduce the computation time up to 40% compared with a naive space division method and achieve about 9 times speedup in case of 32 PEs.
