Design and testing of a multi-sensor pedestrian location and navigation platform.

Morrison A, Renaudin V, Bancroft JB, Lachapelle G - Sensors (Basel) (2012)

Bottom Line: In order to achieve compatibility and flexibility in terms of multiple sensors, an advanced adaptable platform is required.The system provides a research tool for pedestrian navigation, location and body motion analysis in an unobtrusive form factor that enables in situ data collections with minimal gait and posture impact.Testing and examples of applications of the NavCube are provided.

ABSTRACT
Navigation and location technologies are continually advancing, allowing ever higher accuracies and operation under ever more challenging conditions. The development of such technologies requires the rapid evaluation of a large number of sensors and related utilization strategies. The integration of Global Navigation Satellite Systems (GNSSs) such as the Global Positioning System (GPS) with accelerometers, gyros, barometers, magnetometers and other sensors is allowing for novel applications, but is hindered by the difficulties to test and compare integrated solutions using multiple sensor sets. In order to achieve compatibility and flexibility in terms of multiple sensors, an advanced adaptable platform is required. This paper describes the design and testing of the NavCube, a multi-sensor navigation, location and timing platform. The system provides a research tool for pedestrian navigation, location and body motion analysis in an unobtrusive form factor that enables in situ data collections with minimal gait and posture impact. Testing and examples of applications of the NavCube are provided.

f6-sensors-12-03720: Comparison of the steps detected with the handheld inertial sensors (cyan dots) and the strides events detected with the sensors rigidly attached to the left foot (red dots).

Mentions: The handheld IMU senses the footfalls of both feet, whereas a foot mounted IMU senses only the beginning of the foot corresponding to the stride. Figure 6 presents the results of the step detection process and effectively observes this phenomenon since for one footfall, marked with a red dot, and two steps marked with the cyan dots, detection occurs with handheld inertial sensors.
