  1. 1. Learning features for extrinsic camera calibration of wide-angle cameras

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Albin Holmkvist; Max Björkander; [2023]
    Nyckelord :Computer vision; camera calibration; machine learning; artificial intelligence; wireframes;

    Sammanfattning : This thesis attempts to solve the problem of estimating the extrinsic camera parameters (pitch and roll) from a wide-angle view image. The first contributionis a data generation pipeline capable of producing wide-angle distorted images with rotation and line segment annotations. LÄS MER

  3. 2. Windshield Distortion Modelling

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Therese Luong; [2022]
    Nyckelord :windshield distortion; image distortion; camera model;

    Sammanfattning : When a camera system in a car is mounted behind the windshield, light rays will be refracted by the windshield. The distortion can be significant, especially for wide field-of-view cameras. Traditional approaches handle the windshield distortion along with the calibration that calculates the intrinsic and extrinsic parameters. LÄS MER

  4. 3. Camera pose estimation with moving Aruco-board. : Retrieving camera pose in a stereo camera tolling system application.

    Kandidat-uppsats, Jönköping University/JTH, Datateknik och informatik

    Författare :Jakob Isaksson; Lucas Magnusson; [2020]
    Nyckelord :Extrinsic camera calibration; OpenCV; Aruco; Perspective N Point; Tolling system.;

    Sammanfattning : Stereo camera systems can be utilized for different applications such as position estimation,distance measuring, and 3d modelling. However, this requires the cameras to be calibrated.This paper proposes a traditional calibration solution with Aruco-markers mounted on avehicle to estimate the pose of a stereo camera system in a tolling environment.

  5. 4. Machine vision camera calibration and robot communication

    Magister-uppsats, Institutionen för teknik, matematik och datavetenskap

    Författare :Per Stark; [2007]
    Nyckelord :Robotar; Robotteknik;

    Sammanfattning : This thesis is a part of a larger project included in the European project, AFFIX. The reason for the project is to try to develop a new method to assemble an aircraft engine part so that the weight and manufacturing costs are reduced. The proposal is to weld sheet metal parts instead of using cast parts. LÄS MER
