  1. 1. Applying Deep Learning To Improve Optimization- Based Approaches For Robust Sensor Fusion

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pernilla Wikström; [2021]
    Keywords : Inertial Measurement Unit; Zero Velocity UPdaTes; Temporal Convolutional Network; PoseGraph Optimization; Inertial Measurement Unit; Zero Velocity UPdaTes; Temporal Convolutional Network; Optimering av GrafBaserad Positionering;

    Abstract : Recent studies show that deep learning can be employed to learn from sensor data to improve accuracy and robustness of sensor fusion algorithms. In the same vein, in this thesis we use a state-of-the-art temporal convolution network to predict zero velocity updates (ZUPT) from raw inertial measurement unit (IMU) signals, and use the network output to improve the performance of an optimization-based pose estimator.

  3. 2. Calibration and Evaluation of Inertial Navigation with Zero Velocity Update for Industrial Fastening Tools

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johan Rågmark; [2021]
    Keywords : Inertial navigation; Inertial measurement unit; Zero velocity update; Indoor positional navigation; Kalman filter; Tröghetsnavigering; Inertial measurement unit; Zero velocity update; Inomhuspositionering; Kalman filter;

    Abstract : Indoor Positional Navigation (IPN) systems can be used to track the position of tools in factories which is crucial for quality assurance in many manufacturing industries. Inertial navigation is rarely used on its own because of the noisy Inertial Measurement Unit (IMU) sensors which contribute to large drift. READ MORE

  4. 3. Evaluation of drift correction strategies for an inertial based dairy cow positioning system. : A study on tracking the position of dairy cows using a foot mounted IMU with drift correction from ZUPT or sparse RFID locations.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Maria Markovska; Ruben Svensson; [2019]
    Keywords : Inertial navigation system; IMU; PDR; dairy cows; drift correction; ZUPT; sparse locations.; Tröghetsnavigeringssystem; IMU; PDR; mjölkkor; driftkorrigering; ZUPT; sparse locations.;

    Abstract : This thesis investigates the feasibility and performance of an inertial based positioning system for dairy cows in a barn environment. The investigated positioning method is pedestrian dead reckoning using inertial navigation with MEMS sensors. READ MORE

  5. 4. A Study on Positioning for Industrial Tools using Inertial Sensors

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Satyajit Bagchi; [2017]
    Keywords : ;

    Abstract : This thesis investigates the currently achievable estimates of position and orientation using inertial measurement units(IMU) intended for use in indoor positioning of tightening tools. The study first introduces the reader to the problems inherent in estimating position and orientation using inertial measurement units. READ MORE

  6. 5. Indoor Positioning Using Opportunistic Multi-Frequency RSS With Foot-Mounted INS

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan

    Author : Martin Nilsson; [2014]
    Keywords : Particle filters; Simultaneous localization and mapping; Radio navigation; Multisensor integration;

    Abstract : Reliable and accurate positioning systems are expected to significantly improve the safety for first responders and enhance their operational efficiency. To be effective, a first responder positioning systemmust provide room level accuracy during extended time periods of indoor operation. READ MORE
