摘　　要：针对室内行人所处楼层位置感知问题提出了一种结合水平仪和气压计的多层建筑物室内环境中行人楼层高度识别算法。利用水平仪进行行人行走及上下楼状态的识别,并结合气压计完成对行人所处楼层的识别。此方法结合水平仪测量的实时性和气压计数据的连续性,可以准确识别行人所处多层建筑物中的楼层变化。实验结果表明,行人上下楼的识别的准确率可达到93%和91%,对于高度估计的误差在6 m内低于1.6%。In order to solve the problems of indoor continuous high-precision plane positioning and position perception in stairs,a novel method of estimating the floor altitude of pedestrians who are walking in the indoor environment of a multi-story building based on level and barometer is proposed.High-precision estimates of the floor where pedestrians are located were obtained by barometer data,as well as the state of pedestrian walking and up and down,deduced from level data.By combining the real-time measurement of the level and the continuity of the barometer data,this method is established,and floor changes in multi-storey buildings where pedestrians are located can be accurately identified.The experimental results demonstrate that the recognition rates of going upstairs and going downstairs are 93%and 91%respectively,the error of the estimated height of the cumulative height is about 1.6%over a total height of 6 m.
