摘　　要：B样条曲线(B-spline curve)是贝塞尔曲线的一种一般化,具有几何不变性、凸包性、保凸性、变差减小性、局部支撑性等许多优良性质,可用于给几何体建造精确模型。文章介绍了B样条曲线的定义、特征、基本算法,将其应用于无人机航路修正与平滑处理,以保证无人机能在航路上正常飞行,并通过仿真验证其有效性。B-spline curve is a generalization of Bezier curve. It has many excellent properties, such as geometric invariance, convex enveloping, convexity preserving, variation and reduction, local support and so on, can be used to build precise to model geometry. This paper introduces the definition, characteristic and basic algorithm of B-spline curve, and applies it to modify and smooth the route of UAV. In order to ensure that the UAV can fly normally on the route, the effectiveness of the method is verified by simulation.
