  1. 6. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jessica McKenna; [2023]
    Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  3. 7. Point Cloud Registration using both Machine Learning and Non-learning Methods : with Data from a Photon-counting LIDAR Sensor

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Maja Boström; [2023]
    Nyckelord :Point Cloud Registration; Machine Learning; Photon-counting LIDAR; Iterative Closest Point;

    Sammanfattning : Point Cloud Registration with data measured from a photon-counting LIDAR sensor from a large distance (500 m - 1.5 km) is an expanding field. Data measuredfrom far is sparse and have low detail, which can make the registration processdifficult, and registering this type of data is fairly unexplored. LÄS MER

  4. 8. DRONAR: Obstacle echolocation using ego-noise

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Henrik Nilsson; [2023]
    Nyckelord :Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

    Sammanfattning : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. LÄS MER

  5. 9. Autonomous Navigation: LIDAR-based SLAM, Terrain of Technology Explored

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Oscar Sanner; [2023]
    Nyckelord :MSc; SLAM; Pathing; ICP; FastSLAM; LIDAR; Technology and Engineering;

    Sammanfattning : In this thesis, an autonomous system capable of navigating and mapping unknown environments is developed. The solution uses a family of algorithms called SLAM or simultaneous localization and mapping, capable of mapping the environment and retaining accurate position data without external sensors such as GPS.

  7. 10. Poggio Aquilone - Survey and Repurposing in a Medieval Italian Village

    Uppsats för yrkesexamina på avancerad nivå, KTH/Arkitektur

    Författare :Philip Reimers; [2023]
    Nyckelord :Italy; Repurposing; Transformation; Refurbishment; Renovation; Survey; Umbria; Ruin; Rural Tourism; Lidar; drone; scanning; photogrammetry;

    Sammanfattning : The site of this diploma project is the small hilltop village of Poggio Aquilone. The village, situated in the region of Umbria in central Italy, lies roughly halfway between Rome and Florence. LÄS MER
