Inmätning av hårdgjorda ytor
… the methods terrestrial laser scanning (TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements have been applied on two different test surfaces, one of asphalt and one of gravel. The purpose of the comparison is to investigate whether the airborne …
Detta examensarbete undersöker forensisk längdmätning i bild, t ex längduppskattning av människor i bilder rörande brottsmål. Problemen identifieras och några av dagens befintliga längdmätningsmetoder diskuteras. Den metod som bäst uppfyller de i arbetet ställda kraven, d v s …
… photographs. The access to digital aerial photographs and the developments in photogrammetry have led to new opportunities for forest organisations to do the photo interpretation needed to update stand databases on their own. The aim of this Master’s thesis is to compare …
The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy …
En analys av möjliga använda huggverktyg vid byggandet av Alvastra pålbyggnad
This paper deals with the question of with witch tools the Alvastra pile dwelling was built. To reach a result I calculate the curvature on 29 stone axes, 8 double-edged axes and 21 simple-edged axes, used in the middle-neolithic in what today is Sweden. These results are then …
Informationshantering av data insamlad viaUAS
… is to give a general view on how to handle information collectedthrough photogrammetry and laser scanning with the help of UAS. The report ismade in collaboration with WSP Group and will briefly describe howphotogrammetry and laser scanning, also known as Lidar, works and how …
This master thesis was made to investigate the possibilities of using the Matlab-basedsoftware Basegrain to determine grain size distributions of erosion protections onhydropower dams. Basegrain is a photogrammetric tool developed to generate grainsize distributions and other …
Inom skogsbruket i Sverige framställs årligen ett stort antal Skogsbruksplaner (SBPL) där subjektiva fältmätningar vanligtvis används för skattningen av de skogliga variablerna. Denna studie syftade till att undersöka möjligheterna att uppdatera Södras befintliga SBPL med hjälp …
