Abstract

本申请实施例公开了一种指纹定位方法及终端，其中的方法可包括：将待定位区域划分成M个子区域；在所述每个子区域对应的指纹数据库中分别进行筛选，选择所述指纹数据库中的N个AP的BSSID构成参考AP集合，所述N个AP为所述对应的指纹数据库中最大RSSI大于预设阈值的AP，所述每个子区域对应一个所述参考AP集合；比较终端设备接收到的AP的BSSID与所述M个参考AP集合中的BSSID，确定终端设备所在的子区域对应的目标参考AP集合；根据所述目标参考AP集合对应的指纹数据库进行定位计算，确定终端设备所在的位置。采用本申请可以解决现有技术中指纹定位计算过程中由于定位计算量大导致的定位效率较低的问题。
