A stereo vision algorithm based on B spline curve is presented for 3D reconstruction of free curves under the assumption of affine camera model. Because of the affine invariance of B spline curves, a space B spline curve can be reconstructed by just reconstructing its control points. The experimental results demonstrate that comparing with traditional approaches, the algorithm presented is found to be more accurate, simple and robust.
