Description

指纹定位数据的采集方法及装置 技术领域
本发明涉及数据采集领域，具体而言，涉及一种指纹定位数据的采集方法及装置。
背景技术
目前，指纹定位由于其定位精度高，无需增加额外的设备，已经成为定位常用的技术手段，备受各行各业的青睐。指纹定位是用当前定位信息与指纹库中的指纹位置特征数据作匹配，选取相似度最大的指纹位置特征数据作为定位结果。指纹位置特征是由一组无线信号特征数据组成的，代表某一位置的唯一特征信息，所以采集指纹位置特征，构建一个完整、有效的指纹库非常重要，而且指纹库有效数据越丰富，指纹定位精度越高，指纹库也需要实时更新。
相关技术中的指纹位置特征数据采集方式如下：

2、预测采集：采用预测仿真软件，结合区域地理信息以及基站信息，自动生成预测区域内的指纹位置特征数据，形成指纹库；预测采集较人工采集减少了很大的工作量，然而由于真实的地理环境实时的变化，给指纹预测采集的准确度带来了严重的干扰。

在本实施例中提供了一种指纹定位数据的采集方法，图1是根据本发明实施例的指纹定位数据的采集方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，接收用于请求采集指纹定位数据的采集指令，其中，采集指令包括：采集区域；
可选的，采集指令用于触发整个控制采集的流程，采集区域可以是GPS定位效果不好的室内空间或者地下区域，也可以是一般的采集点。采集指令除了采集区域之外，还可以包括采集时间，指定采集终端的终端地址等，其中，采集时间用于指示合适的采集时间段，指定采集终端的终端地址用于提供指定终端的终端物理地址，但本实施例并不限于使用指定的采集终端，使用采集区域内的非指定终端也可以实现本方案，并解决相同的技术问题。
步骤S104，采集位于采集区域内的终端的位置信息，以及终端所在位置的无线信号信息；
在本实施例中，采集区域内可以是一个或多个终端，依据具体的采集环境而定，采集终端的位置和无线信号时，终端的位置是一定的，即，采集终端在采集区域内同一位置的位置信息和无线信号信息。
步骤S106，组合位置信息和无线信号信息构建成采集区域的指纹定位数据。
可选的，将采集区域内同一位置的位置信息和无线信号信息组合成一组相关联的数据，在采集的区域内的多个位置点采集多组相关联的数据，每组数据中的位置信息所显示的终端位置不同，在不同空间位置终端的无线信号信息也不同，这样就构成了指纹定位数据。
通过本实施例，采用接收用于请求采集指纹定位数据的采集指令，其中，采集指令包括：采集区域，然后根据采集指令采集位于采集区域内的终端的位置信息，以及终端所在位置的无线信号信息，最后组合位置信息和无线信号信息构建成采集区域的指纹定位数据，解决了相关技术中人工采集指纹定位数据时工作量大的问题，同时提高了采集数据的准确率，进而达到了提高指纹定位数据的采集效率和可利用率的效果。

可选的，根据上述实施方式，组合位置信息和无线信号信息构建成采集区域的指纹定位数据包括：构建GPS定位数据到由一个或多个信号强度构成的集合的映射关系，将映射关系存储为采集区域的指纹定位数据，其中，由一个或多个信号强度构成的集合包括：无线访问接入点的类型、终端到无线访问接入点的信号强度值。
可选的，采集到终端的GPS定位数据为(A1、B1)，采集到该点C、D、F三个无线访问接入点的信号强度值，分别是10db、18db、23db，则该区域内位置(A1、B1)点的指纹定位数据为{(A1、B1)，(C、10db)、(D、18db)、(F、23db)}，在该区域内采集到多个位置点的位置GPS定位数据到由一个或多个信号强度构成的集合的映射关系后，就可以形成指纹定位数据库。
在根据本实施例的可选实施方式中，在采集位于采集区域内的终端的位置信息，以及终端所在位置的无线信号信息之后，方法还包括：
