The invention relates to the technical field of positioning navigation, and in particular relates to an underground parking lot navigation method for a mobile phone. The method comprises the following steps of: training a behavior action judgment model by utilizing deep learning based on data of a mobile phone sensor; collecting parking lot data, and establishing a parking lot high-precision map in advance; positioning a vehicle starting position, and selecting a target parking space; planning a driving path of the vehicle in the high-precision map of the parking lot according to the starting position of the vehicle and the target parking space position; calculating the moving distance and direction of the vehicle based on data of the mobile phone sensor, obtaining a positioning result, and recording moving track points; registering the moving track points, and correcting a positioning result; predicting a driving behavior of the vehicle; and correcting the next moving track point of the vehicle in combination with the predicted vehicle driving behavior. According to the invention, continuous positioning navigation in the underground parking lot is realized, and low-cost positioning navigation is realized by using the sensor of the mobile phone and the parking lot map acquired in advance.
本发明涉及定位导航技术领域,具体为一种用于手机地下停车场导航方法,基于手机传感器的数据,利用深度学习训练行为动作判断模型;采集停车场数据,并提前建立停车场高精地图;定位车辆起始位置,选择目标车位;通过车辆起始位置和目标车位位置,规划出车辆在停车场高精地图中的行驶路径;基于手机传感器的数据推算车辆的移动距离和方向,获得定位结果,并记录移动轨迹点;对移动轨迹点进行配准,修正定位结果;预测车辆的驾驶行为;结合预测的车辆驾驶行为对车辆下一移动轨迹点进行纠偏校正。本发明实现地下停车场中的连续定位导航,利用手机自带传感器及事先采集的停车场地图实现低成本的定位导航。
