  1. 1. Positional calibration methods for linear pipetting robot

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Oscar Uudelepp; [2020]
    Keywords : linear; robot; pose; calibration; camera; vision; pressure;

    Abstract : This thesis aims to investigate and develop two positional calibration methods that can be applied to a linear pipetting robot. The goal of the calibration is to detect displacements that have been made to objects that are located in the the robot’s reference system and try to estimate their new position. READ MORE

  2. 2. Transformation of Time-based Sensor Data to Material Quality Data in Stainless Steel Production

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Adam Inersjö; [2020]
    Keywords : Time series; Stainless steel; Steel; Sensor data; Digitalization; Aggregation; Continuous production; Outokumpu; Tidsserier; Rostfritt stål; Stål; Sensordata; Digitalisering; Aggregering; Kontinuerlig produktion; Outokumpu;

    Abstract : Quality assurance in the stainless steel production requires large amounts of sensor data to monitor the processing steps. Digitalisation of the production would allow higher levels of control to both evaluate and increase the quality of the end products. READ MORE

  3. 3. Map Matching to road segments using Hidden Markov Model with GNSS, Odometer and Gyroscope

    University essay from Linköpings universitet/Programvara och system

    Author : Hugo Lindholm; [2019]
    Keywords : map matching; hmm; hidden markov model; gnss;

    Abstract : In this thesis the Hidden Markov Model (HMM) is used in the process of map matching to investigate the accuracy for road segment map matching. A few HMM algorithms using a Global Navigation Satellite System (GNSS) receiver, odometer and gyroscope sensors are presented. The HMM algorithms are evaluated on four accuracy metrics. READ MORE

  4. 4. Identification of absolute orientation using inertial measurement unit

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi; Högskolan i Halmstad/Akademin för informationsteknologi

    Author : André Kopfinger; Daniel Ahlsén; [2019]
    Keywords : Indoor navigation; absolute orientation; inertial measurement unit; IMU; indoor positioning;

    Abstract : Because of the limitation of GPS indoors there is a demand for alternative methods to accurately determine both position and orientation. Previous attempts at positional tracking has required an infrastructure of hardware and sensors to provide the path of an object or person. This is not a mobile solution to a mobile problem.

  5. 5. Six DOF tracking system based on smartphones internal sensors for standalone mobile VR

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

    Author : Fredd Duque; [2019]
    Keywords : Virtual reality; Positional tracking; Simultaneous location and mapping; Head-mounted-display;

    Abstract : Nowadays mid-range smartphones have enough computational power to run simultaneous location and mapping (SLAM) algorithms that, together with their onboard inertial sensors makes them capable of position and rotation tracking. Based on this, Google and Apple have released their own respective software development kits (SDKs) that allow smartphones to run augmented reality applications using six degrees of freedom tracking.
