摘要
传统路径规划方法以最短路径准则来设计代价函数,显然其规划结果已无法满足特种车辆在道路损毁、恶略天气和行进安全等多约束条件下的应急行动路径规划需求。为了优化设计复杂环境下特种车辆的机动路径,本文通过分析应急行动过程中路径规划的目标条件和约束条件,在研究Dijkstra算法和A*算法基础上,设计了不同目标条件下的代价函数,利用PostGIS数据库构建开发了机动路径规划计算软件。实验结果表明,研发成果具备快速性和安全性条件下的机动路径规划功能。
The traditional path planning method uses the shortest path criterion to design the cost function.Obviously,the planning results can not meet the emergency action path planning requirements of special vehicles under the constraints of road damage,bad weather and travel safety.In order to optimize the maneuvering path of special vehicles in complex environments,the paper analysed the objective and constraint conditions of path planning in emergency operations,designed cost functions under different objective conditions on the basis of studying Dijkstra algorithm and A*algorithm,and developed calculation software path planning using PostGIS database.The experimental results show that the software achievement has the function of mobile path planning under the conditions of rapidity and security.
