3D Laserskanning : Verktyg för antikvarisk dokumentation / 3D Laser scanning : A tool for heritage documentation

Colfach, Peder January 2017 (has links)
Uppsatsen 3D laserskanning som verktyg för antikvarisk dokumentation är en jämförande studie som bygger på tre fallstudier i form ut av två privata och en offentlig fastighet där man använder sig ut av 3D laserskanning som verktyg för någon form ut av   byggnadsdokumentation. Den går genom hur en 3D laserskanning genomförs i praktiken samt beskriver på ett vardagligt sätt hur tekniken fungerar. Genom intervjuer och tidigare forskning försöker uppsatsen ringa in om det finns antikvariska ambitioner från beställarna i dessa fallstudier. Uppsatsen belyser även fördelarna att använda 3D laserskanning som metod för byggnadsdokumentation på kulturhistoriska byggnader. Resultatet ger tydliga   indikationer på att beställarna ser fördelarna med laserskanning ett verktyg för antikvarisk byggnadsdokumentation. Uppsatsen vill skapa en diskussion kring hur man kan gå tillväga för att uträtta en kulturhistorisk byggnadsdokumentation som passar vår tid. / This study aims to figure out if there is any heritage aspect when documenting heritage buildings with 3D laser scanning in Sweden. The paper is based on three case studies of two privately owned and one public building where the purpose for 3D scanning has had different goals. In simple words this paper aims to describe what laser scanning is and how you work with the laser scanning in the field.  Through comparing results from prior studies on the matter, this study also aims to describe the advantages that come from using 3D laser scanning on heritage buildings. This study finally wants to bring up the subject and discuss the terms and uses of fulfilling a building heritage documentation that suites our time.

Rekonstruktion av Ör kyrkas tidigmedeltida takkonstruktion / Reconstruction of Ör church early medieval roof structure

Lorentsson, Jimmy, Forssgren, David January 2022 (has links)
During an inventory of Ör church’s roof structure in 2021, it was discovered that the roofstructure above the church’s nave contains a large amount of reused structural parts froman earlier roof structure. The reused structural parts are most likely originated from Örchurch’s early medieval roof structure.This thesis is an attempt to reconstruct the early medieval roof structure with the use of3D-laser scanning. The goal is to present a possible shape and 3D-model of the earlymedieval roof structure. The existing roof structure will also be documented. One aim ofthe thesis is to develop and evaluate the method of using 3D-laser scanning for thispurpose.The reconstruction resulted in eight different shapes and 3D-models of the early medievalroof structure. The documentation of the existing roof structure above the nave resulted inupdated section, plan and detailed drawings.The method of using 3D-laser scanning gave a detailed point cloud of the existing roofstructure. The point cloud had low density points in certain parts of the roof structurewhich is a consequence from the implementation of the 3D laser scanning. For thismethod a field study and planning in advance is recommended for best possible result.
