The invention discloses a parking guiding method, and the method comprises the steps: packaging a LoRa module and a geomagnetic sensor to form LoRa geomagnetism, and burying the LoRa geomagnetism below each parking space in a one-to-one manner; the method comprises the following steps that: a LoRa module receives a parking space, sets a two-dimensional coordinate formed by coordinates x and y for each parking space, records the two-dimensional coordinate in LoRa geomagnetism, and when a local magnetic sensor senses that the occupation condition of the parking space is changed, the LoRa module wirelessly transmits the two-dimensional coordinate and current parking space state information to a LoRa gateway together, and further transmits the two-dimensional coordinate and the current parking space state information to a background server; the server issues parking space state information and provides parking navigation to clients through the Internet; in the path planning of parking navigation, determining and calibrating three types of key point coordinates, namely a starting coordinate, a target coordinate and an obstacle coordinate; wherein the initial coordinate is fixed at the entrance of the parking lot, the target coordinate is obtained by calculating each LoRa terrestrial magnetism and the initial coordinate, and finally, the shortest path from the initial coordinate to the target coordinate is calculated through an A * algorithm to guide a vehicle owner to park.

    本发明公开了一种停车引导方法,将LoRa模块和地磁传感器封装形成LoRa地磁,以一对一方式埋于每个停车位下方;同时为每个停车位设定一个由坐标x、y构成的二维坐标并记录在LoRa地磁中,当地磁传感器感应到停车位占用情况发生变化时,LoRa模块将该二维坐标与当前车位状态信息一同通过无线传递至LoRa网关,进而传至后台服务器;服务器通过互联网向客户下发车位状态信息以及提供停车导航;在停车导航的路径规划中,确定标定三类关键点坐标,分别是起始坐标、目标坐标和障碍物坐标;其中,起始坐标固定在停车场入口处,目标坐标由各个LoRa地磁与起始坐标进行计算后得出,最后通过A*算法算出从起始坐标到目标坐标之间的最短路径,引导车主泊车。
