  4. 3. Detecting Faulty Tape-around Weatherproofing Cables by Computer Vision

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ruiwen Sun; [2020]
    Nyckelord :Object Detection; Image Processing; OpenCV; YOLO; Line Segment Detector; Objektdetektion; Bildbehandling; OpenCV; YOLO; Linjesegmentdetektor;

    Sammanfattning : More cables will be installed owing to setting up more radio towers when it comes to 5G. However, a large proportion of radio units are constructed high in the open space, which makes it difficult for human technicians to maintain the systems. Under these circumstances, automatic detections of errors among radio cabinets are crucial. LÄS MER

  5. 4. Improving Conventional Image-based 3D Reconstruction of Man-made Environments Through Line Cloud Integration

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Författare :Martin Gråd; [2018]
    Nyckelord :Image-based 3D reconstruction; SfM; MVS; Poisson surface reconstruction; line cloud; point cloud; PCA; k-d tree;

    Sammanfattning : Image-based 3D reconstruction refers to the capture and virtual reconstruction of real scenes, through the use of ordinary camera sensors. A common approach is the use of the algorithms Structure from Motion, Multi-view Stereo and Poisson Surface Reconstruction, that fares well for many types of scenes. LÄS MER

  7. 5. Estimation and Correction of the Distortion in Forensic Image due to Rotation of the Photo Camera

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Sathwika Bavikadi; Venkata Bharath Botta; [2018]
    Nyckelord :Hough Transformation; Hough Circular Transformation; Image Rotation; Forensic Scales.;

    Sammanfattning : Images, in contrast to text, represent an effective and natural communication media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recognition are one of the most important tasks in the image processing. LÄS MER
