The advantage of skeleton-based 3D reconstruction is to com- pletely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruc- tion but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbi- trary number of calibrated acquisitions. The main contribu- tion is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the num- ber of topology changes to map the 3D skeleton topology to topologies on images is minimum. This way, the number of matched branches is maximum.
