The invention discloses a parking lot navigation method, a parking lot navigation device and an intelligent parking lot system. The parking lot navigation method comprises the following steps: 1, setting parking spaces of a parking lot and intersections of vehicle driving roads as Nodes and numbering the Nodes; setting driving roads between the Nodes as Lines and numbering the Lines; 2, establishing an openlist and a closelist, and emptying the openlist and the closelist; obtaining a Node closest to the current position of the vehicle as a starting node Node1, and adding the Node1 into the openlist; and 3, inspecting the nodes which are in the openlist and are not in the closelist until a destination node is found, and tracing back to the starting node according to a father node of the destination node to obtain a path from the starting node to the destination node. The method is simple in algorithm and easy to implement, and can quickly obtain the path from a vehicle starting positionto a target parking space.
本发明公开了一种停车场导航方法、装置和智慧停车场系统,其中停车场导航方法包括:1、将停车场的停车位、车辆行驶道路的交叉路口处设置为节点Node并编号;节点Node之间的行驶道路设置为Line并编号;2、建立openlist表和closelist表并清空;获取距离车辆当前位置最近的Node点作为起始节点Node,将Node加入openlist;3、对在openlist中且不在closelist中的节点进行考察,直到找到目的地节点,并根据目的地节点的父节点追溯到起始节点,得到从起始节点到目的地节点的路径path。该方法算法简单,易于实现,能够快速获取车辆起始位置到目的停车位之间的路径。
