摘要

在不熟悉的复杂高层建筑中,用户不仅需要了解楼层的二维平面位置信息,还需要获取楼层的Z轴信息。根据这一需求,我们提出了一种基于多传感器的室内三维定位机制,整合气压检测和地磁检测信息辅助惯性导航进行标定,并对检测信息进行综合处理。该机构基于动态气压楼层判别模型,根据当前实际楼层、通过各楼层的平均时间和各楼层的高度,实时确定用户所在楼层;根据楼层标准地磁信息数据,基于地磁实时定位模型计算当前位置的地磁坐标,实时获取楼层人员及楼层平面位置。在机构定位过程中,不需要额外的硬件设备或网络信号,只需要气压计传感器和地磁传感器即可完成建筑物室内三维实时定位,实际应用方便,适应性广。

3D Indoor Localization Mechanism Based on Multiple Sensors
In unfamiliar complicated high-rise building, users not only have to understand the 2D plane location information of floor, but also need to obtain the Z axis information of floor. According to this requirement, we proposed a 3D indoor localization mechanism based on multi-sensor, which integrates the air pressure examination and geomagnetic examination information to assist inertial navigation for calibration, and conduct integrated processing of examined information. The mechanism is based on the dynamic air pressure floor discrimination model, and according to the actual current floor, average time spent by passing each floor and the height of each floor, determine the floor of user in a real-time manner; according to the standard geomagnetic information data of floor, compute the geomagnetic coordinates of current location based on the geomagnetic realtime localization model, and obtain the floor of personnel and the plane location on the floor in a real-time manner. During the localization process of mechanism, it does not require additional hardware equipment or network signal, but only needs the air pressure gauge sensor and geomagnetic sensor to complete the indoor 3D real-time localization of building, which is convenient in practical application with broad adaptability.
