  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. Industrial 3D Anomaly Detection and Localization Using Unsupervised Machine Learning

    University essay from Linköpings universitet/Datorseende

    Author : Kevin Bärudde; Marcus Gandal; [2023]
    Keywords : Machine Learning; 3D Anomaly Detection; Feature Extraction; Manufacturing; Computer Vision; Vision Transformer; PointNet;

    Abstract : Detecting defects in industrially manufactured products is crucial to ensure their safety and quality. This process can be both expensive and error-prone if done manually, making automated solutions desirable. READ MORE

  4. 3. Feature-Aware Point Transformer for Point Cloud Alignment Classification : Pose your pose to FACT

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Ludvig Dillén; [2023]
    Keywords : point cloud alignment; point cloud alignment classification; alignment validation; point cloud; map validation; map quality; misalignment recognition; alignment quality; point transformer; Sinkhorn divergence; differential entropy; point cloud co-visibility; point cloud visibility; SLAM; point cloud registration; point cloud density;

    Abstract : As the demand for 3D maps from LIDAR scanners increases, delivering high-quality maps becomes critical. One way to ensure the quality of such maps is through point cloud alignment classification, which aims to classify the alignment error between two registered point clouds. READ MORE

  5. 4. Design, implementation and evaluation of a daylight estimation tool using 3D city model data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Peter Nezval; [2021]
    Keywords : 3D city model; CityJSON; solar energy; free and open-source software; 3D feature extraction; solar urban planning; sustainable urban development; geomatics; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : Solar energy is an important component of sustainable urban development. However, it is still not reaching its full potential due to several reasons. One of them is a lack of free tools based on open geodata capable of estimating solar energy (daylight) metrics on building features, e.g. READ MORE

  6. 5. Robust Registration of ToF and RGB-D Camera Point Clouds

    University essay from KTH/Fastigheter och byggande

    Author : Shuo Chen; [2021]
    Keywords : Robustness; Estimator; Feature extraction; RANSAC; BLAVE; M-estimator; ToF; RGB-D; Robusthet; Uppskattare; Särdragsextraktion; RANSAC; BLAVE; M-uppskattare; ToF; RGB-D;

    Abstract : This thesis presents a comparison of M-estimator, BLAVE, and RANSAC method in point clouds registration. The comparison is performed empirically by applying all the estimators on a simulated data added with noise plus gross errors, ToF data and RGB-D data. The RANSAC method is the fastest and most robust estimator from the comparison. READ MORE
