摘　　要：针对城市高楼、隧道、室内外等多种复杂环境下单源导航定位系统的定位精度低、可靠性差和不连续等问题,提出一种基于GPS、MIMU、表面肌电信号(SEMG)传感器、三维电子罗盘的SINS/GPS/PDR室内外无缝导航定位算法。利用SEMG传感器配合三维电子罗盘进行行人航位推算,同时以捷联惯导为主,多传感器辅助的方式建立多源信息融合模型,设计自适应联邦卡尔曼滤波算法。行走测试结果表明,该方法能够实现室内外无缝导航定位,多源融合的精度水平优于1.5 m(室外)/2 m(室内),显著改善了定位精度与连续性。In order to solve the problems of low positioning accuracy,poor reliability and discontinuity of the single-source navigation and positioning system in various complex environments such as urban high-rise buildings,tunnels,indoors and outdoors,a SINS/GPS/PDR indoor and outdoor seamless navigation and positioning algorithm based on GPS,MIMU,surface electromyographic(SEMG)signal sensor,and three-dimensional electronic compass was proposed.By using the SEMG sensor and the three-dimensional electronic compass for pedestrian dead reckoning,while by using strapdown inertial navigation as the main method,a multi-source information fusion model was established based on a multi-sensor assisted method,and an adaptive federated Kalman filter algorithm was designed.The walking test results showed that the method could achieve seamless indoor and outdoor navigation and positioning,and the accuracy level of multi-source fusion was better than 1.5 meters(outdoor)/2 meters(indoor),which significantly improved the positioning accuracy and continuity.
