Abstract:The traditional A* algorithm iswidelyused for path planning in static environments,butwhen facing the special longandnarrowformofriver,itspathplanningisoftenineficientduetooverlysimplenodeexpasionmethods.Onthisbasis, an improved A* algorithm forunmannedsurfacevehicle path planning isproposed.Theadaptabilityandeficiency of the traditional A ∴∗ algorithm in the narow and long river environment are optimized by combining the region segmentation and jump pointsearchtechniques.Theregionsegmentationmethodisusedtosignificantlydistinguishtheriverchannelintomultiple rectangularregions,andthesearch processisoptimizedbymeansofthejump-pointalgorithmtoreducetheinefectivenode expansion,thusacelerating thepath search.Anadaptive heuristicfunctionisintroduced toadjustthesearchpriorityof the nodesbyconsideringtheterraincharacteristicsofthepath,whichefectivelyreducestheredundantpartsofthepathand unecessry turns,and improves thestraightnessandoveralleficiencyof pathplanning.Thesimulationresultsshowthatthe improved algorithmisbetter thanthe traditional A algorithmin terms of path length,number of turning points and computation time,whichverifiesthepracticalityandsuperiorityoftheproposedalgorithmforunmannedsurfacevehiclepathplanninginriver environment.
