  1. 1. Accuracy and Reliability of 3D Scanning Spatial Data when Capturing Limb Morphology for Use within Prosthetics and Orthotics: A Scoping Review

    University essay from Jönköping University/HHJ. Ortopedteknisk plattform

    Author : Miles Bailey-Brændgaard; Peter Wibe Enevoldsen; [2022]
    Keywords : Scanner; 3D; Accuracy; Reliability; Validity; Prosthetics; Orthotics; Shape capture; Measurement; Human; Shape; Morphology; Assessment;

    Abstract : Background: Scanners are becoming widespread in Prosthetics and Orthotics, replacing plaster casting in the manufacture of some types of devices. P&O shape capture must be accurate and reliable, so the device is comfortable and reproducible between clinicians/sessions. READ MORE

  2. 2. Lens Distortion Correction Without Camera Access

    University essay from Linköpings universitet/Datorseende

    Author : Emily Olsson; [2022]
    Keywords : Lens distortion; Lens distortion correction; Perspective n-Point; Camera calibration;

    Abstract : Lens distortions appear in almost all digital images and cause straight lines to appear curved in the image. This can contribute to errors in position estimations and 3D reconstruction and it is therefore of interest to correct for the distortion. If the camera is available, the distortion parameters can be obtained when calibrating the camera. READ MORE

  3. 3. Extraoral 3D-scanning - conformity between extraoral 3D scanning and clinical measurements of the face

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Angelica Persson; Amanda Lindewald; [2021]
    Keywords : clinical measurements; conformity; extraoral scanning; orthodontics; 3D scanning;

    Abstract : Aim: To use the extraoral scanner 3D Sense in practice and compare the measurements on scanned material with conventional, direct clinical measurements. This is to evaluate if extraoral scanning can replace a clinical examination and extraoral 2D photography. READ MORE

  4. 4. 3D Scanner : Scanning small objects and recreating them visually as a mesh in a computer

    University essay from KTH/Mekatronik; KTH/Mekatronik

    Author : Carl Egenäs; Axel Sacilotto; [2021]
    Keywords : Mechatronics; 3D Scanner; Arduino; Stepper Motor; Mesh; Mekatronik; 3D-Scanner; Arduino; Stegmotor; Mesh;

    Abstract : The purpose of this project was to construct a 3D scanner capable of scanning smaller objects and visualize them in a computer with satisfying accuracy. The goal was then to generate an STL file able to be 3D printed in an attempt at reverse engineering. READ MORE

  5. 5. An investigation of detecting potholes with UAV LiDAR and UAV Photogrammetry

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Linus Hedenström; Sebastian Eriksson; [2021]
    Keywords : UAV; LiDAR; photogrammetry; potholes; point clouds; SfM; paved; pavement; road; drone; UAV; LiDAR; fotogrammetri; potthål; drönare; asfalt; väg; punktmoln; SfM;

    Abstract : Potholes are caused by erosion and as such always emerging on our roadnetwork. Potholes may not only cause great damages to vehicles, but can alsocause road accidents, which in the worst case are fatal. READ MORE
