1. Applying Deep Learning To Improve Optimization- Based Approaches For Robust Sensor Fusion
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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.

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)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
