Description

一种校准方法 技术领域
[0001] 本发明属于定位领域, 尤其涉及一种校准方法。
背景技术
[0002] 基于位置信息的服务已经得到广泛的应用, 其中大众最为熟知的是利用 GPS ( Global Positioning System, 即全球定位***) 对车辆导航。 在现有的基于位置信 息的服务中, 绝大部分只能应用于室外。
[0003] 如果希望在室内实现长吋间 (比如几年) 的定位追踪服务, 一般需要在室内安 装一系列基站。 基站可以被认为是"室内卫星", 通过多个基站协作, 则可以实现 "室内 GPS***"。 在基站初装完毕后, 需要经过校准才能投入使用, 校准的目的 是消除***误差从而保证定位精度。 如果某个基站被更换或被移动, 则在更换 或移动完成以后, 所有的基站需要被重新校准。 如果室内环境发生重大变化, 校准工作也需要重新进行。 即使室内环境没有重大的变化, 定期的校准 (例如 一个月一次) 可以消除漂移误差, 从而保持定位精度。
[0004] 为了完成一次完备的校准, 校准器件必须尽可能遍历整个室内空间, 因此, 一 般需要花费巨大的吋间和代价。 为避免经常性的校准, 在某些室内定位方案中 , 一些校准器件被永久性地安装在室内的某些固定位置; 显然, 永久性地大范 围地安装校准器件在实际中会带来很大不便。
技术问题
[0005] 本发明实施例的目的在于提供一种校准方法, 旨在解决现有应用于室内定位系 统的校准成本高的问题。
问题的解决方案

[0009] 所述无线信号收发装置, 用于和室内定位***以无线方式交换定位信号。
发明的有益效果
有益效果
[0010] 本发明实施例在校准过程中使用惯性导航装置测量位置信息。 惯性导航装置可 以实吋自主地 (即, 不依赖任何其它设备) 测量位置信息, 另外可选地, 惯性 导航装置可以利用小车的速度信息进一步提升其位置测量精度; 所以, 在校准 过程中小车可以高速不停地移动, 从而可以在短吋间里完成完备的校准。 本发 明实施例的校准方法具有通用性, 可以校准各种不同的室内定位***。 本发明 实施例的校准器件轻便便携, 可以被方便的搬移到任何室内环境。 以上优点使 得本发明实施例的校准方法可以大幅降低室内定位***的校准成本。
