Research And Implementation Of Intelligent Tourism System Based On VRGIS

In recent years,as the enhancement of people's material life level,tourism has become a relaxation and leisure activity for people.But infrastructures of many scenic areas are not perfect at present.And qualities of tour guide are still poor.These problems led to the losing of the children and the old man on scenic area in recent years.What's more,similar public secure problems have occurred occasionally.These problems caused the tourists giving a hurried and cursory glance at sightseeing tour,and caused poor experiences for the tourists.As the rise of mobile Internet,wisdom tourism products also appear constantly in the market.Most of these products take public security or scenic route recommendation as the breakthrough point to provide services for tourists.But the products can offer accurate scenic navigation service and personalized travel planning(Personalized Travel Planning PTP)for tourists are very few.So it is necessary to develop a system that provides accurate navigation services and personalized tourism planningTo solve above problems,this paper made improvement and optimization of path evaluation,path planning and dynamic adjustment on the basis of VRGIS technology and intelligent recommendation algorithm in view of the scenic spot.First of all,this paper proposes the discretization modeling of scenic area space.The discrete modeling of the scenic space makes the continuous problem discretized,so that the intelligent algorithm is convenient to optimize the target problem.Secondly,this paper puts forward the path evaluation rules,and personalizes the route for tourists according to their favor in the process of searching routes,and finds out the highest satisfied route.Third,this paper improves the updating operator of path recommendation algorithm,and makes the operator sort into original sequence according to the priority rules.It can greatly improve the efficiency of calculation.Fourth,the dynamic programming is to ensure planning a new route for tourist when tourism is not fit with the plan,and it improves the adaptability of system.In this paper,the three-dimensional simulation experiment is based on the East Campus of Beijing University of Chemical Technology.The campus building is taken as the scenic spot and the campus road as the scenic road network.The route search algorithm,the route recommendation algorithm,the route evaluation and the route dynamic adjustment strategy are applied in the system.Experiments show that the system can achieve precise positioning,and achieve the customization of visitors through the route search or route recommendation,and can achieve the dynamic adjustment of the route.And the proposed algorithm is proved to be highly efficient and feasible.
