A Robust and Ubiquitous Multi-Sensor Fusion-based Floor Localization System


Prof. Moustafa Youssef

13:30- / March 18th (Mon.)


Room 1509, 15th floor, NII


Floor localization is an integral part of indoor localization systems that are deployed in any typical high-rise building. Nevertheless, while many efforts have been made to detect floor change events leveraging phone-embedded sensors, there are still a number of pitfalls that need to be overcome to provide robust and accurate localization in the 3D space. In this presentation, we present a robust and ubiquitous probabilistic crowdsourcing-based floor determination system. Our proposed system is a hybrid system that combines the barometer sensor and the ubiquitous WiFi access points installed in the building into a probabilistic framework to identify the user's floor. In particular, the system incorporates a discrete Markov localization algorithm where the motion model is based on the vertical transitions detected from the sampled pressure readings and the observation model leverages a Multilayer Perceptron neural network to fuse the outputs of various learners that detect the most probable floor of the user based on statistical properties of the observed WiFi scan. The system also has provisions to handle practical deployment issues including handling the inherent drift in the barometer readings, the noisy wireless environment, heterogeneous devices, among others.
