摘要

This paper describes the path smoothing technique forrnUAV using clothoid curve method. The resultant smoothrnpath is flyable by UAV considering the UAVs kinematicrnconstraint such as minimum turning radius. The solutionrnis divided into two phases. The first phase involves therngeneration of collision free, piece-wise linear path basedrnon visibility graph method. In the second phase, anrnalgorithm to generate clothoid curve based on Fresnelrnintegral is designed and implemented. The path generatedrnis flyable by the UAV since it has gradual transitionrnbetween linear segments. Furthermore, the path allows thernUAV to pass through the given waypoints. Simulationrnresults are included to illustrate the proposed method.
