摘要
在仿射相机模型的假设下 ,提出了一种基于 B样条曲线的立体视觉方法来重建三维自由曲线 .利用 B样条曲线的仿射不变性 ,通过重建控制点来重建空间 B样条曲线 .实验结果证明 ,较之传统方法该方法重建精度更高、算法复杂性更低 ,且具有鲁棒性 .
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.
