Multi-source fusion positioning method

Abstract

The invention discloses a multi-source fusion positioning method. The method comprises the following steps: acquiring to-be-corrected positioning information through a micro electro mechanical system sensor group in a user terminal; a target positioning algorithm corresponding to the user terminal is determined, reference positioning information is determined according to the target positioning algorithm, and the target positioning algorithm is a positioning algorithm executed by the user terminal through an action hotspot; and correcting the to-be-corrected positioning information according to the reference positioning information to obtain target positioning information corresponding to the user terminal. According to the invention, the positioning results output by the two positioning sources of the action hot spot and the micro electro mechanical system sensor are fused, and the problem that an accurate positioning result is difficult to obtain by using a single indoor positioning source in the prior art is solved. 本发明公开了一种多源融合定位方法，所述方法包括：通过用户终端内的微机电系统传感器组获取待修正定位信息；确定所述用户终端对应的目标定位算法，根据所述目标定位算法确定参考定位信息，其中，所述目标定位算法为所述用户终端通过行动热点执行的定位算法；根据所述参考定位信息对所述待修正定位信息进行修正，得到所述用户终端对应的目标定位信息。本发明的融合了行动热点和微机电系统传感器两种定位源输出的定位结果，解决了现有技术中使用单一的室内定位源难以得到准确的定位结果的问题。
