3D Reconstruction of Free-form Objects Based on CB-spline Curve

A algorithm based on CB-spline curves is presented for 3D reconstruction of 3D objects.CB-spline Curves which have the property of the affine invariance can be used as primitives to reconstruct 3D objects under the assump- tion of the affine camera model.Experiments demonstrate that this algorithm presented is more accurate and robuster than other approaches.
