  1. 16. Visual Odometryin Principle and Practice

    Författare :Mikael Persson; Michael Felsberg; Klas Nordberg; Per-Erik Forssén; Janne Heikkilä; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual Odometry; Continuous Pose Trajectory; P3P; PNP; VO; Tracking; Calibration;

    Sammanfattning : Vision is the primary means by which we know where we are, what is nearby, and how we are moving. The corresponding computer-vision task is the simultaneous mapping of the surroundings and the localization of the camera. This goes by many names of which this thesis uses Visual Odometry. LÄS MER

  3. 17. Homography-Based Positioning and Planar Motion Recovery

    Författare :Mårten Wadenbäck; Mathematical Imaging Group; []
    Nyckelord :;

    Sammanfattning : Planar motion is an important and frequently occurring situation in mobile robotics applications. This thesis concerns estimation of ego-motion and pose of a single downwards oriented camera under the assumptions of planar motion and known internal camera parameters. LÄS MER

  4. 18. Vision-based Perception For Autonomous Robotic Manipulation

    Författare :Dinh-Cuong Hoang; Todor Stoyanov; Achim Lilienthal; Per-Erik Forssén; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In order to safely and effectively operate in real-world unstructured environments where a priori knowledge of the surroundings is not available, robots must have adequate perceptual capabilities. This thesis is concerned with several important aspects of vision-based perception for autonomous robotic manipulation. LÄS MER

  5. 19. View Planning and Refractive Modeling for Structure and Motion

    Författare :Sebastian Haner; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Structure and Motion; 3D Reconstruction; View Planning; Refractive Modeling;

    Sammanfattning : This thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy.

  7. 20. Local visual feature based localisation and mapping by mobile robots

    Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. LÄS MER
