- Step count algorithm adapted to indoor localizationPublication . Terra, Rui; Figueiredo, Lino; Barbosa, Ramiro; Anacleto, RicardoThis paper presents a step count algorithm designed to work in real-time using low computational power. This proposal is our first step for the development of an indoor navigation system, based on Pedestrian Dead Reckoning (PDR). We present two approaches to solve this problem and compare them based in their error on step counting, as well as, the capability of their use in a real time system.
- Traveled Distance Estimation Algorithm for Indoor LocalizationPublication . Terra, Rui; Figueiredo, Lino; Barbosa, Ramiro S.; Anacleto, RicardoThis paper presents an ankle mounted Inertial Navigation System (INS) used to estimate the distance traveled by a pedestrian. This distance is estimated by the number of steps given by the user. The proposed method is based on force sensors to enhance the results obtained from an INS. Experimental results have shown that, depending on the step frequency, the traveled distance error varies between 2.7% and 5.6%.
