本发明实施例提供的楼栋位置的确定方法，可以应用于用户携带终端设备进入楼栋的场景，本发明实施例中所涉及的楼栋可以为办公楼、居民楼和商业 楼等。
实施例一
如图1所示，本发明实施例提供一种楼栋位置的确定方法，该方法可以包括下述步骤：
101、终端设备获取第一位置信息和第二位置信息。
其中，第一位置信息为第一时间点检测到的位置信息，第一时间点为最后检测到GPS信号的衰减量大于或等于预设变化量的时间点，第二位置信息为第二时间点检测到的位置信息，第二时间点为首次检测到气压值以目标变化量进行变化的时间点。
可选的，上述预设变化量可以根据实际情况进行设置，本发明实施例不作限定。
可选的，上述目标变化量也可以根据实际情况进行设置，本发明实施例不作限定。
在用户携带终端设备进入楼栋的过程中，由于GPS信号可能会存在一个衰减的过程，在衰减的过程中，可能存在多个GPS的衰减量大于或等于预设变化量的时间点，本发明实施例中的上述第一时间点即为在整个衰减过程中最后检测到GPS信号的衰减量大于或等于预设变化量的时间点。
可选的，本发明实施例中，第一位置信息和第二位置信息具体可以为通过GPS定位的方式检测到的位置信息，也可以为通过无线保真(Wireless Fidelity，WI-FI)技术定位或者蓝牙定位的方式检测到的位置信息。
需要说明的是，在实际中存在一种极端情况，在第一时间点GPS信号可能会衰减至没有信号，此时在第一时间点无法通过GPS定位的方式检测到位置信 息，这时可以将第一时间点之前，最接近第一时间点的时刻检测到的位置信息作为第一位置信息。
102、终端设备根据第二位置信息、第一位置信息、第一时间点和第二时间点，计算第二位置信息与第一位置信息之间的运动轨迹。
可选的，本发明实施例中，上述102可以通过下述步骤实现：
102a、终端设备根据第一位置信息和第二位置信息分别确定起始点和终止点。
102b、终端设备计算第二时间点与第一时间点之间的时间差，以得到第一时长。
102c、终端设备计算终端设备在第一时长内从起始点到终止点的运动轨迹。
可选的，上述102c具体可以根据下述两种方式实现：
方式一：
终端设备根据步行者航位推算(Pedestrian Dead Reckoning，PDR)算法，计算终端设备在第一时长内从起始点到终止点的运动轨迹。
终端设备可以采用惯性测量单元(Inertial Measurement Unit，IMU)感知携带终端设备的用户在行进过程中的加速度、角速度、磁力和压力等数据，并利用这些数据对用户的行进步长与行进方向进行推算，从而获取终端设备的用户或终端设备的运动轨迹。
其中，PDR算法中，可以根据初始位置，用户在行进过程中的加速度、角速度、磁力和压力等数据，实时估计用户的行进步长与行进方向，并根据行进步长和行进方向确定出多个位置点，并进一步根据该多个位置点确定出终端设 备的用户或终端设备的运动轨迹。
方式二：
终端设备获取第一时长内终端设备的多个GPS定位信息，根据多个GPS定位信息计算终端设备在第一时长内从起始点到终止点的运动轨迹。
在有GPS信号的情况下，终端设备可以获取第一时长内终端设备在该起始点与终止点之间的多个GPS定位信息，根据该多个GPS定位信息可以计算终端设备在第一时长内的运动轨迹。
103、终端设备从运动轨迹中确定出第三位置信息，作为楼栋的位置信息。
由于通常终端设备在接近楼栋，即将进入楼栋时GPS信号会大幅度的衰减，因此本发明实施例中，通过在第一时间点(即最后检测到GPS信号的衰减量大于或等于预设变化量的时间点)所检测到的第一位置信息，可以认为是终端设备在楼栋的外部，靠近楼栋的位置(记为第一位置)。
而通常在终端设备处于楼栋内部的情况下，在用户携带终端设备在楼栋内部上楼或下楼的过程中，由于终端设备所在高度的变化，终端设备所在位置的气压值会持续的以一定的变化量变化，因此本发明实施例中，通过在第二时间点(即首次检测到气压值以目标变化量进行变化的时间点)检测到的位置信息，可以确定为终端设备在楼栋内部的楼梯或电梯的位置(记为第二位置)。
进一步的，由于第一位置信息为终端设备在楼栋的外部，靠近楼栋的位置，而第二位置信息为终端设备在楼栋内部的楼梯或电梯的位置，因此在确定了终端设备从第一位置到第二位置之间的运动轨迹之后，则可以确定在运动轨迹中处于第一位置与第二位置之间的一个点的位置作为楼栋的位置，该点的位置信息即为上述的第三位置信息。
可选的，可以确定在运动轨迹中处于该轨迹的中间位置作为楼栋的位置，该点的位置信息即为上述的第三位置信息。
本发明实施例提供一种楼栋位置的确定方法，终端设备可以获取最后检测到GPS信号的衰减量大于或等于预设变化量的第一时间点、在该第一时间点检测到的第一位置信息、首次检测到气压值以目标变化量进行变化的第二时间点和在该第二时间点检测到的位置信息，并根据第二位置信息、第一位置信息、第一时间点和第二时间点，计算第二位置信息与第一位置信息之间的运动轨迹，从该运动轨迹中确定出第三位置信息，作为楼栋的位置信息。可见，实施本发明实施例，可以通过GPS信号的衰减的情况和气压值的变化情况，确定终端设备户从楼栋外部进入楼栋内部，并计算终端设备从楼栋外部进入楼栋内部的运动轨迹，以及从该运动轨迹中确定出楼栋的位置，从而相比于现有技术中采用GPS来定位楼栋的位置，准确性更高。
可选的，本发明实施例中，在上述103之后，终端设备可以根据上述第三位置信息和上述运动轨迹，计算终端设备进入楼栋的第三时间点。其中，第三时间点为终端设备到达第三位置信息所指示的位置的时间点。
本发明实施例中，在上述运动轨迹中确定出第三位置之后，可以结合该轨迹的起始点和终止点所对应的第一时间点和第二时间点估算，终端设备到达第三位置时的时间点，并将估算出的时间点作为终端设备进入楼栋的时间点。
由于本发明实施例中，不仅能精确的确定楼栋的位置信息，还能进一步确定出终端设备进入楼栋的时间点，从而还可以实现对终端设备的位置的追踪。
实施例二
结合图1，如图2所示，在上述103之后，本发明实施例提供的楼栋位置 的确定方法还可以包括下述步骤：
104、终端设备检测当前的气压值。
可选的，终端设备可以通过终端设备中的气压计传感器检测当前的气压值。
105、终端设备根据该当前的气压值和终端设备所在地区的海平面气压值，确定终端设备当前的海拔高度。
通常，每个地区的海平面气压值为一个确定的值。
本发明实施例中，可以根据当前终端设备的气压值和终端设备所在地区的海平面气压值，计算出终端设备当前的海拔高度。
106、终端设备终根据海拔高度确定终端设备在楼栋中的楼层。
通常楼栋的楼层高度有一定的高度范围。例如，每层楼的高度在3至4米之间。本发明实施例中，根据海拔高度和每层楼的高度可以估算出终端设备在楼栋中的楼层高度。
本发明实施例中，终端设备可以直接根据检测到的气压值，确定终端设备在该楼栋中的楼层，从而不仅可以进行楼栋的定位，还可以实现对终端设备在楼栋内部的楼层更加精准的定位。
可选的，结合图2，如图3所示，本发明实施例提供的楼栋位置的确定方法还可以包括下述步骤：
107、终端设备获取搜索到的无线接入点的信号强度。
可选的，上述搜索到的无线接入点的信号强度是指搜索到的每个无线接入点的信号强度，这里的无线接入点的数量可以为一个或者多个。
可选的，该无线接入点可以是指蓝牙接入点和/或WI-FI接入点。
108、终端设备将无线接入点的信号强度以及楼层的楼层标识发送至服务器。
其中，终端设备将无线接入点的信号强度以及楼层的楼层标识发送至服务器，以使其他设备向服务器发送无线接入点的信号强度之后获取服务器推送的楼层的楼层标识，从而可以方便其他设备获取其所在楼层的标识。
本发明实施例中，服务器可以保存多组无线接入点的信号强度与楼层的楼层标识之间的对应关系。这样在其他设备向服务器发送无线接入点的信号强度之后，终端设备可以从保存的对应关系中，确定出与该无线接入点的信号强度对应的楼层的楼层标识，并将该楼层标识推送给该设备。
由于其他设备可以通过向服务器发送无线接入点的信号强度，就可以方便的获取服务器推送的楼层标识，因此对于没有气压计传感器的设备来说，可以通过与服务器的交互来获知终端设备当前所在的楼层。
终端设备可以通过检测的终端设备当前的气压值，获取终端设备当前所在的楼层信息，并将搜索到的无线接入点的信号强度和楼层信息一起上报至服务器，以使得服务器可以保存终端设备上报的搜索到的无线接入点的信号强度和楼层信息的对应关系，并且服务器可以实时的根据不同终端设备上报的信息，更新服务器中保存的对应关系。进一步的，还可以使其他终端设备向服务器发送无线接入点的信号强度之后，获取服务器推送的与该无线接入点的信号强度对应的楼层信息。
作为一种可选的实现方式，在上述103之后，终端设备可以获取搜索到的无线接入点的信号强度，在获取搜索到的无线接入点的信号强度之后，显示用户输入界面，以提示用户输入当前所在楼层信息，然后终端设备可以接收用户 输入楼层信息的输入，并响应于该输入获取当前所处的楼层信息，以及向服务器发送获取的搜索到的无线接入点的信号强度和当前所处的楼层信息。
通过上述可选的实施方式，终端设备可以通过用户的输入获取终端设备当前所在的楼层信息，并将搜索到的无线接入点的信号强度和楼层信息一起上报至服务器，以使得服务器可以保存终端设备上报的搜索到的无线接入点的信号强度和楼层信息的对应关系，并且服务器可以实时的根据不同终端设备上报的信息，更新服务器中保存的对应关系。进一步的，还可以使其他终端设备向服务器发送无线接入点的信号强度之后，获取服务器推送的与该无线接入点的信号强度对应的楼层信息。
作为一种可选的实现方式，在上述103之后，终端设备可以根据楼栋的位置信息，确定楼栋标识(可以为楼栋的名称)，并获取与该楼栋对应的推荐信息，该推荐信息可以用于向终端设备的用户推荐与该楼栋相关的生活服务类信息。其中，该生活服务类信息可以包括商铺、停车场和该楼栋内部的地图等信息。
其中，终端设备可以通过大数据获取与该楼栋标识对应的推荐信息，或者借助终端设备中安装的第三方应用程序获取与该楼栋标识对应的推荐信息。
终端设备根据楼栋的位置信息，确定楼栋标识的方法可以包括：根据楼栋的位置信息，结合高精度的地图信息可以确定出该楼栋的名称。
通过上述可选的实现方式，终端设备在获取楼栋的定位信息之后，可以根据该定位信息确定终端设备的用户所在的楼栋标识(例如，获知用户在某个商场)，此时可以进一步根据楼栋标识获取与该楼栋对应的推荐信息，以向终端设备的用户推荐与该楼栋相关的生活服务类信息。从而可以根据楼栋的位置信 息为用户实时推荐与该楼栋相关的生活服务类信息，以为用户提供多样化的信息。
实施例三
结合图1，如图4所示，在上述103之后，本发明实施例提供的楼栋位置的确定方法还可以包括下述步骤：
109、终端设备获取搜索到的无线接入点的信号强度。
110、终端设备将无线接入点的信号强度发送至服务器。
相应的，终端设备将搜索到的无线接入点的信号强度发送至服务器之后，服务器可以将搜索到的无线接入点的信号强度(即为第一强度)与服务器中保存的无线接入点的信号强度与楼层的对应关系进行对比，确定与该第一强度对应的楼层，然后将楼层信息(可以为楼层标识)发回给终端设备。
可选的，在上述110之前，服务器保存了多组无线接入点的信号强度与楼层信息的对应关系。具体的，在上述110之前，一些终端设备(可以为本发明实施例中的端设备，也可以为其他的终端设备)可以获取搜索到的无线接入点的信号强度和当前所处的楼层信息，并向服务器发送搜索到的无线接入点的信号强度和当前所处的楼层信息，然后服务器可以将接收到的每组无线接入点的信号强度和当前所处的楼层信息以对应关系的形式保存。
111、终端设备获取服务器发送的与无线接入点的信号强度对应的楼层标识。
112、终端设备根据楼层标识，获知终端设备在楼栋中的楼层。
上述实现方式中，终端设备可以通过向服务器发送无线接入点的信号强度，以获取服务器推送的楼层标识，从而不仅可以进行楼栋的定位，还可以通 过终端设备与服务器的交互实现对终端设备在楼栋内部更加精准的定位。
需要说明的是，本发明实施例中，上述各个附图所示的车辆控制方法均是以结合本发明实施例中的一个附图为例实例性的说明的。具体实现时，上述各个附图所示的车辆控制方法还可以结合上述实施例中示意的其他可以结合的任意附图实现，此处不再赘述。
