The invention relates to a reverse vehicle searching method and system based on Bluetooth beacons and a medium, and the method comprises the steps: G1, building a vehicle body coordinate system based on the Bluetooth beacons laid in a parking area with a vehicle as an original point, and obtaining the coordinate matrix data information of the Bluetooth beacons; g2, based on the coordinate matrix data information of the Bluetooth beacons, the user enters the parking area, RSSI values are sent according to the Bluetooth beacons, and coordinate data information of the position of the user is obtained in real time; and G3, based on the coordinate data information of the position of the user, performing path planning by adopting an improved ant colony algorithm to obtain coordinate data information from the user to a vehicle path point, and performing curve fitting by adopting a Fresnel integral-cleat spiral algorithm. According to the invention, the problem of difficulty in vehicle searching in a city-like parking lot such as a shopping mall, a hospital, an office building and the like in daily life is solved, and the practical problems of large distance deviation, signal interference, high cost and the like caused by positioning distance measurement are solved.

    本发明涉及一种基于蓝牙信标反向寻车的方法、系统及介质,所述方法包括G1.基于停车区域铺设的蓝牙Beacon信标,以车辆为原点,建立车体坐标系,得到蓝牙信标的坐标矩阵数据信息;G2.基于所述蓝牙信标的坐标矩阵数据信息,用户进入停车区域,根据蓝牙Beacon信标发送RSSI值,实时获取用户的位置的坐标数据信息;G3.基于所述用户的位置的坐标数据信息,采用改进的蚁群算法进行路径规划,得到用户到车辆路径点的坐标数据信息,采用菲涅尔积分‑羊角螺线算法进行曲线拟合。本发明不仅解决日常生活中在商场、医院、写字楼等偌大停车场内,寻车难的问题,而且解决定位测距,出现的距离偏差大,信号受干扰,成本高等实际问题。
