1. 1. 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

3. 2. Robotics Approach in Mobile Laser Scanning : Generation of Georeferenced Point-based Forest Models

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

   Author : Tamas Faitli; [2023]
   Keywords : mobile laser scanning; rotating lidar; slam; real-time positioning; georeferencing; state estimation; lidar odometry; point-based forest model; forest harvester; forestry; mobil laserskanning; roterande lidar; slam; realtidspositionering; georeferens; tillståndsuppskattning; lidarodometri; punktbaserad skogsmodell; skogsskördare; skogsbruk;

   Abstract : A mobile laser scanning (MLS) system equipped with a lidar, inertial navigation system and satellite positioning can be used to reconstruct georeferenced point-based models of the surveyed environments. Ideal reconstruction requires accurate trajectories that are challenging to obtain in forests. READ MORE

4. 3. Extracting masts of overhead supply and street lights from point cloud

   University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

   Author : Yi Zhu; [2019]
   Keywords : Support Vector Machine; point cloud; laser scanning; automatic extraction;

   Abstract : Regular inspection and documentation for railway assets are necessary to monitor the status of the traffic environment. Mobile Laser Scanning (MLS) makes it possible to collect highly accurate spatial information of railway environments in the form of point cloud, and an automatic method to extract interested objects from the point cloud is needed to avoid too much manual work.

5. 4. Backpack-based inertial navigation and LiDAR mapping in forest environments

   University essay from Umeå universitet/Institutionen för fysik

   Author : Tjernqvist Mattias; [2017]
   Keywords : lidar; gnss; ins; mls; forest;

   Abstract : Creating 3D models of our surrounding world has seen a rapid increase in research and development over the last few years. A common method is to use laser scanners. Mapping is done either by ground based systems or airborne systems. READ MORE

6. 5. Development of a Workflow for Automatic Classification and Digitization of Road Objects Gathered with Mobile Mapping

   University essay from KTH/Geodesi och satellitpositionering

   Author : Jacob Ekblad; Jacob Lips; [2015]
   Keywords : Mobile Mapping; Automatic classification; Laser scanning; Road;

   Abstract : Mobile Mapping Systems gathers a lot of spatial data that can be used for inventory and analyses regarding road safety. The main purpose of this thesis is to propose a workflow for automatic classification and digitisation of objects in a point cloud gathered by a Mobile Mapping System. READ MORE
