  1. 1. Operation and Area Restriction of Autonomous Wheel Loaders Using Colour Markings

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Jonathan Fernkvist; Inas Hamzic; [2023]
    Keywords : Colour markings; Histogram; Line-following; Machine vision; Mapping; Wheel loader;

    Abstract : This thesis aims to create a system using colour markings for Volvo’s autonomous wheel loaders which determines their restricted area and operation using sensors available on the machine. The wheel loader shall be able to interpret and distinguish different colours of spray paint, and depending on the colour, act accordingly. READ MORE

  3. 2. Assessing tree modeling algorithm from terrestrial laser scanning in Rumperöd mixed forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stig Sand; [2023]
    Keywords : Terrestrial laser scanning; Hough transform algorithm; TreeLS; Rumperöd; Biology and Life Sciences;

    Abstract : Recent technological advancements have revolutionized tree inventory methods for the forest industry. The development of terrestrial laser scanning (TSL) and automatized tree recognition software to estimate crucial tree parameters such as diameter at breast height (DBH) has made the inventory work faster and more reliable.

  4. 3. Camera Distortion Calibration through Fringe Pattern Phase Analysis

    University essay from Linköpings universitet/Datorseende

    Author : Karl Karlsson; [2023]
    Keywords : fringe-pattern; distortion; monogenic signal; phase analysis;

    Abstract : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. READ MORE

  5. 4. A heuristic approach to screw pose detection

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

    Author : Emil Ransed; [2022]
    Keywords : ;

    Abstract : Object detection using vision systems could generally be accomplished using machine learning or conventional computer vision techniques. This thesis implements and compares three methods to locate screws on a flat plane using conventional computer vision on regular non stereo images without any depth or range information. READ MORE

  6. 5. Machine-vision-based Detection of Paper Roll Core Eccentricity : Fast and Robust On-Line Measurement Using Circular Hough Transform

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Erik Sehlstedt; [2022]
    Keywords : Eccentricity; Core eccentricity; Paper roll; Machine vision; Computer vision; Hough transform; Circular Hough transform; Defect detection; On-line measurement; Quality control;

    Abstract : The field of computer vision offers tools that allow machines to derive meaningful infor-mation from video and images and consequently make decisions based on visual inputs. In the paper industry, implementation of machine vision (MV) can be used to automate and speed up processes that require visual inspection, particularly certain segments of quality control – one such application being detection and measurement of paper roll core eccentricity.
