  1. 36. Visualization and Interaction with 3D Data

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Dennis Trollsfjord; [2023]
    Nyckelord :point cloud; change detection; t2c; m3c2; lidar; os0-128; open3d; cloudcompare;

    Sammanfattning : This paper presents Triangle-To-Cloud (T2C), a new approach for point cloud change detection. The method is compared to the established method Multiscale Model to Model Cloud Comparison (M3C2) on the accuracy to detect changes, from a point cloud to another. LÄS MER

  3. 37. Inventering av skred genom jämförelse av två generationer LiDAR-genererad höjddata

    Författare :Klara Alm; [2023]
    Nyckelord :Landslides; LiDAR; multi-temporal; DoD; visual observation;

    Sammanfattning : Landslides are a natural hazard that is expected to increase in the future, due to climate change. In order to keep risk management plans up to date, an efficient inventory method is needed. LÄS MER

  4. 38. Image and RADAR fusion for autonomous vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xavier de Gibert Duart; [2023]
    Nyckelord :Image; Camera; Computer Vision; Data Fusion; Sensors; 3D data processing; Point Clouds; Calibration; MATLAB and RADAR; RADAR; kamera; datorseende; datafusion; sensorer; 3D-databehandling; punktmoln; kalibrering; MATLAB Image;

    Sammanfattning : Robust detection, localization, and tracking of objects are essential for autonomous driving. Computer vision has largely driven development based on camera sensors in recent years, but 3D localization from images is still challenging. Sensors such as LiDAR or RADAR are used to compute depth; each having its own advantages and drawbacks. LÄS MER
