1. 1. Learning features for extrinsic camera calibration of wide-angle cameras

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Albin Holmkvist; Max Björkander; [2023]
   Nyckelord :Computer vision; camera calibration; machine learning; artificial intelligence; wireframes;

   Sammanfattning : This thesis attempts to solve the problem of estimating the extrinsic camera parameters (pitch and roll) from a wide-angle view image. The first contributionis a data generation pipeline capable of producing wide-angle distorted images with rotation and line segment annotations. LÄS MER

3. 2. Start-up of a Kistler 9129AA dynamometer on a custom rotation machine and investigation of its potential eligibility for cutting force measurement in wood

   Master-uppsats, Luleå tekniska universitet/Träteknik

   Författare :Frank Schleicher; [2023]
   Nyckelord :dynamometer; cutting forces in wood; rotation machine; wood cutting;

   Sammanfattning : In the manufacturing industry, the mechanics of metal-cutting is well-understood and used to improve cutting processes. The mechanics of wood-cutting are still in its early stages and further research is required. LÄS MER

4. 3. Real Time Vehicle Detection for Intelligent Transportation Systems

   Magister-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Elda Shurdhaj; Ulehla Christián; [2023]
   Nyckelord :Unmanned aerial vehicles UAVs ; vehicle detection; CNN architecture; snow cover; NVD; Yolov5s; Yolov8s; Faster R-CNN; real-time processing; edge devices;

   Sammanfattning : This thesis aims to analyze how object detectors perform under winter weather conditions, specifically in areas with varying degrees of snow cover. The investigation will evaluate the effectiveness of commonly used object detection methods in identifying vehicles in snowy environments, including YOLO v8, Yolo v5, and Faster R-CNN. LÄS MER

5. 4. A Comparative Study of Machine Learning Algorithms for Angular Position Estimation in Assembly Tools

   Master-uppsats, KTH/Matematisk statistik

   Författare :Henrik Fagerlund; [2023]
   Nyckelord :applied mathematics; circular fully convolutional network; nearest neighbour method; power tools; threaded fasteners; neural network; machine learning; convolution; tillämpad matematik; cirkulärt faltningsnätverk; närmaste granne-metod; elverktyg; skruvförband; neuralt nätverk; maskininlärning; faltning;

   Sammanfattning : The threaded fastener is by far the most common method for securing components together and plays a significant role in determining the quality of a product. Atlas Copco offers industrial tools for tightening these fasteners, which are today suffering from errors in the applied torque. LÄS MER

7. 5. Assessment of Lower Limb Muscle Strength: Feasibility and Implementation on Exxentric’s SingleExx Machines

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Maximilian Geisler; [2023]
   Nyckelord :Force measurement; Lower limb strength; Symmetry assessment; Flywheel-based leg extension machine; Prototype development; Isokinetic dynamometer; Kraftmätning; Styrka i nedre extremiteterna; Symmetribedömning; Flywheel- baserad benförlängningsmaskin; Prototyputveckling; Isokinetisk dynamometer;

   Sammanfattning : Measuring lower limb strength and symmetry is a common practice in elite sports to determine the return to sports point in time during rehabilitation, and this information could be useful for amateur athletes too. However, the devices used for this are highly sophisticated and hardly accessible. LÄS MER
