  2. 6. Estimation-based iterative learning control

    Author : Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Jian-Xin Xu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; Automatic control; Reglerteknik;

    Abstract : In many  applications industrial robots perform the same motion  repeatedly. One way of compensating the repetitive part of the error  is by using iterative learning control (ILC). The ILC algorithm  makes use of the measured errors and iteratively calculates a  correction signal that is applied to the system. READ MORE

  4. 7. Single and Multiple Motion Field Estimation

    Author : Magnus Hemmendorff; Hans Knutsson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a framework for estimation of motion fields both for single and multiple layers. All the methods have in common that they generate or use constraints on the local motion. Motion constraints are represented by vectors whose directions describe one component of the local motion and whose magnitude indicate confidence. READ MORE

  5. 8. Motion and Structure Estimation From Video

    Author : Johan Hedborg; Michael Felsberg; Per-Erik Forssén; Reinhard Koch; Linköpings universitet; []
    Keywords : ;

    Abstract : Digital camera equipped cell phones were introduced in Japan in 2001, they quickly became popular and by 2003 outsold the entire stand-alone digital camera market. In 2010 sales passed one billion units and the market is still growing. READ MORE

  6. 9. Solutions and their ambiguities for structure and motion problems

    Author : Magnus Oskarsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

    Abstract : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. READ MORE

  7. 10. Pose Estimation and Structure Analysis of Image Sequences

    Author : Johan Hedborg; Michael Felsberg; Tomas Werner; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; KLT; GPU; structure from motion; stereo; pose estimation; TECHNOLOGY; TEKNIKVETENSKAP; Image analysis; Bildanalys; Signal processing; Signalbehandling;

    Abstract : Autonomous navigation for ground vehicles has many challenges. Autonomous systems must be able to self-localise, avoid obstacles and determine navigable surfaces. READ MORE
