According to the Bluetooth positioning method for the large-scale three-dimensional bus parking lot, in the large-scale three-dimensional bus parking lot, a Bluetooth gateway is used for obtaining data of Bluetooth beacons on buses, a database server obtains the data and calculates the positions of the Bluetooth beacons through a positioning algorithm, and therefore the positions of the buses are determined and sent to a mobile intelligent terminal; comprising the following steps: S1, arranging a Bluetooth gateway and Bluetooth beacon equipment; s2, the Bluetooth gateway obtains Bluetooth beacon data; s3, searching a target Bluetooth beacon; s4, smoothing the signal intensity value through Kalman filtering; s5, calculating the distance between the Bluetooth gateway and the Bluetooth beacon; s6, calculating the position of the Bluetooth beacon; and S7, matching the position of the Bluetooth beacon with the map of the parking lot. The system is low in equipment cost and easy to deploy, and can densely cover a large three-dimensional bus parking lot; by using the method of the invention, the bus can be accurately positioned. The method does not depend on a data fingerprint database, so that the scene change does not make the method invalid.

    大型立体公交停车场的蓝牙定位方法,在大型立体公交停车场,利用蓝牙网关获取公交车上蓝牙信标的数据,数据库服务器获取该数据并通过定位算法计算蓝牙信标的位置,从而确定公交车位置,并发送到移动智能终端;包括:S1,布置蓝牙网关和蓝牙信标设备;S2,蓝牙网关获取蓝牙信标数据;S3,寻找目标蓝牙信标;S4,卡尔曼滤波平滑信号强度值;S5,计算蓝牙网关与蓝牙信标距离;S6,计算蓝牙信标位置;S7,蓝牙信标位置与停车场地图匹配。本发明设备成本低且易部署,可密集覆盖大型立体公交停车场;利用本发明方法可准确定位公交车。因不依靠数据指纹库,场景的变换不会使本发明方法失效。
