  1. 1. Fjärrmätning av spårdjup i skogsterräng med drönare och digital stereofotogrammetri

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Rasmus Wictorsson; [2019]
    Keywords : fjärranalys; hjulspår; 3D-Point Clouds; tracks; soil disturbance;

    Abstract : Markstörning i form av spårbildning och kompaktering av marken är oftast påtagliga vid maskinellt avverkade områden. Skoglig inventering och kartläggning av skogsrelaterade skador med hjälp av flygfotografering har används sedan 1970-talet. READ MORE

  4. 4. Development of a Laboratory Test Method for Assessment of Crater Wear Volume on Inserts for Steel Turning

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

    Author : Joakim Sandberg; [2019]
    Keywords : Crater wear; turning; focus variation; volume;

    Abstract : This thesis project was carried out at Sandvik Coromant in Västberga, Sweden with the purpose of developing a new laboratory test method for volumetric assessment of crater wear on inserts for steel turning. The test method was developed with the Sandvik Coromant´s existing crater wear measurement method as a starting point. READ MORE

  5. 5. Object identication in 3D urban environments

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Olivier Marion; [2019]
    Keywords : ;

    Abstract : This project investigates the problem of object identification in three-dimensional (3D) urban models represented by meshes. More specifically, the objective is to detect defects or poorly rendered objects, called artefacts, in order to remove them later on. READ MORE
