Fachgebiet Augmented Reality Technische Universität München Introduction / Motivation Tracking is one of the main tasks in Augmented Reality. Should be precise, accurate, and robust, as possible. Need multiple sensors → Sensor Fusion Deep Learning is a very trending topic !! Akyazı: Sensor Fusion with Deep Learning 3
Fachgebiet Augmented Reality Technische Universität München Problem Description: Issues Using 2 or more IMU sensors, realize sensor fusion to get the position, orientation, acceleration and angular velocity of a target. Existing solutions for sensor fusion are almost all analytical approaches. These methods have a drawback of sensor registration. State of the art solutions require very deep mathematical knowledge Akyazı: Sensor Fusion with Deep Learning 4
