  1. 1. 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.

  2. 2. 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.

  3. 3. Speckles in Coherent LiDAR

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ivar Nyman; [2022]
    Keywords : Spckle; LiDAR; coherent;

    Abstract : Speckles are a phenomenon which often appears in situations involving lasers. Their properties can be used as an advantage but in the case of LiDAR applications, they’re purelydestructive. The peaks and troughs of the intensity distribution across the collimatinglens can be seen as variations in signal strength at the detector. READ MORE

  4. 4. 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. 5. Environmental comparison of LiDAR and Camera in a simulated CARLA environment

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Philip Sokcic Hedin; [2022]
    Keywords : ;

    Abstract : Computer vision for autonomous vehicles is a widely studied and quickly evolving field of research. It can be difficult to know when one technology is performs better or worse, and in which scenario it's worth it to spend the additional resources on LiDAR. READ MORE
