  1. 11. A Deep Learning Based Approach to Object Recognition from LiDAR Data Along Swedish Railroads

    University essay from KTH/Fastigheter och byggande

    Author : Egil Morast; [2022]
    Keywords : Deep learning; DGCNN; LiDAR; Object recognition; Railroad; Automatisation; Sweden; Point cloud; Djupinlärning; DGCNN; LiDAR; Objektigenkänning; Järnväg; Automatisering; Sverige; Punktmoln;

    Abstract : Malfunction in the overhead contact line system is a common cause of disturbances in the train traffic in Sweden. Due to the preventive methods being inefficient, the Swedish Transport Administration has stated the need to develop the railroad maintenance services and has identified Artificial Intelligence (AI) as an important tool for this undertaking.

  3. 12. Autonomous Propulsion for a GPR-UGV

    University essay from Umeå universitet/Institutionen för fysik

    Author : Fredrik Wall Eskilsson; [2022]
    Keywords : robotics; gpr; autonomous; robot; ros; slam;

    Abstract : This thesis presents the research and development behind the integration of an autonomous propulsion system for a four-wheeled Ground Penetrating Radar (GPR) measurement unit, previously requiring manual operation. In order to ease the administration of the complex new system, Robot Operating System (ROS) 2 was used as middleware, where an implementation of Light Detection And Ranging (LiDAR) 3D-SLAM (Simultaneous Localization And Mapping) served to secure precise localization of the Unmanned Ground Vehicle (UGV) and mapping of its environment.

  4. 13. Design and evaluation of a solid-state LiDAR system : for wireless distance measurements

    University essay from Uppsala universitet/Signaler och system

    Author : Christian Hagstedt; Sebastian Jönsson; [2022]
    Keywords : Solid-state; LiDAR; Python; Raspberry Pi; Switching regulator; PCB; 3D Printing;

    Abstract : The advent of smarter vehicles coupled with declining costs for solid-state light detection and ranging (LiDAR) sensors unlocks the potential of cheaper devices that experience less mechanical wear while providing smaller form factors. The early state of the market makes evaluating the limited supply of available sensors interesting. READ MORE

  5. 14. LiDAR Point Cloud De-noising for Adverse Weather

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Johan Bergius; Jesper Holmblad; [2022]
    Keywords : Semantic Segmentation; Lidar point cloud; CNN; GAN; CycleGAN; Unsupervised; LiOR; DSOR; DROR; WADS;

    Abstract : Light Detection And Ranging (LiDAR) is a hot topic today primarily because of its vast importance within autonomous vehicles. LiDAR sensors are capable of capturing and identifying objects in the 3D environment. However, a drawback of LiDAR is that they perform poorly under adverse weather conditions. READ MORE

  6. 15. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

    University essay from Umeå universitet/Institutionen för fysik

    Author : Christoffer Elebro; [2022]
    Keywords : GPS; GNSS; RTK; Lidar; 3D-mapping;

    Abstract : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. READ MORE
