Indoor and outdoor seamless positioning and navigation library self-construction method

Abstract

The invention discloses an indoor and outdoor seamless positioning and navigation library self-construction method. The method comprises the following steps: acquiring initial positioning data output based on a sensor; acquiring a first receiving state corresponding to a global navigation satellite signal and a second receiving state corresponding to received signal strength data, and determining error data corresponding to the initial positioning data according to the first receiving state, the second receiving state and the initial positioning data; and acquiring positioning data output based on a sensor, and correcting the positioning data according to the error data to obtain target positioning data. The problem that correct indoor or outdoor positioning information of a user is difficult to obtain by using a sensor on a mobile phone due to the lack of a technology for correcting the positioning information output by the sensor in the prior art is solved. 本发明公开了一种室内外无缝定位及导航库自构建方法，所述方法通过获取基于传感器输出的初始定位数据；获取全球导航卫星信号对应的第一接收状态和接收信号强度数据对应的第二接收状态，根据所述第一接收状态、所述第二接收状态以及所述初始定位数据，确定所述初始定位数据对应的误差数据；获取基于传感器输出的定位数据，根据所述误差数据对所述定位数据进行修正，得到目标定位数据。解决了现有技术中缺乏对传感器输出的定位信息进行修正的技术，因此利用手机上的传感器难以得到用户在室内或者室外的正确定位信息的问题。
