摘　　要：提出了均匀三次B-spline曲线反算的快速算法。在Matlab中编程实现,大大降低了程序的复杂性,提高了运算效率,并使重构所得曲线的两个端点处曲率不为零,满足了一阶连续,并给出了应用实例。A rapid algorithm working out control points of uniform cubic B-spline is proposed. It is realized in Matlab, which greatly reduced the complexity of program and improved the operation efficiency. At the same time, the curvature of the two endpoints on the reconstructed curve is not zero, then first-order continuity is achieved. and some examples are described at last.
