【Abstract】 A fast algorithm for reconstruction of a convex singly connected 3 dimensional object using 2 dimensional photos is presented. The basic idea is to shoot from different angles a series of photos of a convex singly connected 3 dimensional object positioned on a turn table, and then combine the 2 dimensional information by tracing the rays to obtain the 3 dimensional coordinates of the points on the surface of the object. Compared to some available methods, our algorithm significantly saves space, the accuracy is independent of the resolution, and the speed is also greatly improved especially when the object has large volume.更多还原
