Abstract: This paper proposes an earthenware reconstruction sys-tem, which can automatically reconstruct some earthen-ware from numerous given potsherds in two dimensional grayscale images. The system supposes that given potsherds are thin and moderately flat and small. Some earthenware having three dimensional shape, such as crocks, can be reconstructed by the system within the supposition. The system performs earthenware reconstruction through two phases. At the first phase, potsherds are joining automatically in two dimensions. An efficient joint detection algorithm using surface pattern and shape similarity is proposed at the phase. At the second phase, three dimensional shape is recovered by adequate three dimensional transformation. In this paper, some experimental results of reconstruction from numerous potsherds are also reported.
