  1. 1. Generative adversarial network for point cloud upsampling

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Edison Widell Delgado; [2024]
    Keywords : Point cloud upsampling; Generative adversarial network; GAN;

    Abstract : Point clouds are a widely used system for the collection and application of 3D data. But most timesthe data gathered is too scarce to reliably be used in any application. READ MORE

  3. 2. Evaluation of SLAM based mobile laser scanning and terrestrial laser scanning in the Kiruna mine : A comparison between the Emesent Hovermap HF1 mobile laser scanner and the Faro Laser Scanner Focus3D X 330 terrestrial laser scanner

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Claes Gustafsson; [2023]
    Keywords : Terrestrial laser scanning; mobile laser scanning; simultaneous localization and mapping; underground mapping; Kiruna mine.;

    Abstract : The mining industry has over the last few decades seen a drastic increase in the usage of laser scanning technologies as a way of creating 3D maps of the mines being exploited. Underground mapping in places such as mines has become more prevalent as the technology has progressed and made it easier to generate highly detailed point clouds faster. READ MORE

  4. 3. 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

  5. 4. Clustering on groups for human tracking with 3D LiDAR

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Simon Utterström; [2023]
    Keywords : Computer Vision; Computer Science; AI; Machine Learning; clustering; Kernel Density Clustering; tracking; LiDAR; 3D LiDAR; tracking; human; pedestrian; real time; Datavetenskap; Dataseende; clustering; SLR; CVC; KDEG; KDE; Kernel Density Clustering; HDBSCAN; DBSCAN; LiDAR; point cloud; tracking; human; pedestrian;

    Abstract : 3D LiDAR people detection and tracking applications rely on extracting individual people from the point cloud for reliable tracking. A recurring problem for these applications is under-segmentation caused by people standing close or interacting with each other, which in turn causes the system to lose tracking. READ MORE

  6. 5. Static Extrinsic Calibration of a Vehicle-Mounted Lidar Using Spherical Targets

    University essay from Umeå universitet/Institutionen för fysik

    Author : Philip Sandström; [2023]
    Keywords : ;

    Abstract : Self-driving cars are steadily becoming a reality by a growing number of driver assistance functions enabled by smart perception sensors. The light detection and ranging (lidar) sensor show great potential for perception tasks due to its precise distance measurements. READ MORE
