  1. 1. An evaluation study of 3D imaging technology as a tool to estimate body weight and growth in dairy heifers

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Emelie Ahlberg; [2024]
    Keywords : body measurement; body weight; growth; heifer; three-dimensional imaging; young stock management;

    Abstract : The aim of this thesis was to evaluate the use of a 3D camera as a tool to estimate body weight and growth in dairy heifers. Data collection lasted from October 2022 to January 2023 and was performed at the Swedish Livestock Research Centre in Uppsala, Sweden. READ MORE

  3. 2. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Mathias Billenberg; [2023]
    Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

    Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

  4. 3. Improving a Background Model for Tracking and Classification of Objects in LiDAR 3D Point Clouds

    University essay from Lunds universitet/Matematik LTH

    Author : Seamus Doyle; Gustav Nilsson; [2022]
    Keywords : LiDAR; Semantic Segmentation; Neural Networks; RandLA-NET; 3D Point Cloud; Gaussian Process Regression; Robust Locally Weighted Regression; CARLA; Ground Model; Technology and Engineering;

    Abstract : This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. READ MORE

  5. 4. Estimating Forest Variables from LiDAR Pointcloud Data Using a Deep Learning Approach

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Ella Grundin; Rasmus Kozak Åslöv; [2022]
    Keywords : Deep Learning; Forest Management; Machine Learning; Measuring Forests; Neural Networks; Data Analysis; Digital Edge; Djupinlärning; Skogsbruk; Maskininlärning; Skogsmätning; Neurala nätverk; Dataanalys; Digital Edge;

    Abstract : Knowledge about forest measurements is essential for efficient and sustainableforestry. One important measurement is wood volume, both from an economicand an environmental perspective. Therefore it is crucial to measure wood vol-ume accurately and reliably. READ MORE

  6. 5. ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gabriela Olekszyk; [2022]
    Keywords : Geography; GIS; Lidar; ALS; Point cloud; Accuracy; Quality; Technology and Engineering;

    Abstract : Gabriela Olekszyk ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand. Lidar (Light Detection and Ranging) data is becoming more widely available and accessible. READ MORE
