Application of Augmented Reality in BIM

Abstract

The main objective of the master ‘s thesis was to analyze the AR (Augmented Reality) together with BIM (Building Information Modeling). Compare and find advantages and disadvantages of two created applications which are web-based AR application and Unity engine based AR application as well as application used in the industry GAMMA AR. Furthermore, another goal was to find how these different applications can be used. The web-based application was created using AR.js open-source code, and Unity engine was used to create a second application. The 3D model which was used in the AR application was created from the point cloud data of the floor of the Faculty of Civil Engineering in Riga Technical University. The whole process of creation of web-based application and Unity engine-based application was showcased and explained. The result of the master’s thesis was that the different AR applications has different uses as well as some applications like Unity engine based application require more knowledge to create or use. The created application have basic usage for viewing and analyzing but with required knowledge can have added functionality and features which will have the requirements for different uses in the field.

Pagrindinis magistro darbo tikslas – išanalizuoti AR (papildytąją realybę) kartu su BIM (statinio informaciniu modeliavimu). Palyginti ir rasti dviejų sukurtų programų, t. y. žiniatinkliu pagrįstos AR programos ir "Unity" platforma pagrįstos AR programos, taip pat pramonėje naudojamos programos GAMMA AR privalumus ir trūkumus. Dar vienas magistro darbo tikslas, buvo išsiaiškinti, šių skirtingų programų naudojimo galimybes. Žiniatinklio programa buvo sukurta naudojant AR atvirojo kodo kodą, o antrajai programai sukurti – naudojama "Unity" platforma. Naudojamas AR programoje 3D modelis sukurtas panaudojant Rygos technikos universiteto Statybos fakulteto taškų rinkinio duomenis. Šiame magistro darbe pademonstruotas bei paaiškintas visas žiniatinkliu pagrįstos taikomosios programos ir "Unity" platforma paremtos taikomosios programos kūrimo procesas. Magistro darbo gautas rezultatas toks, kad skirtingos AR taikomosios programos turi skirtingą paskirtį, kai kurioms taikomosioms programoms, pvz., "Unity" platforma pagrįstai programai, sukurti ar naudoti reikia daugiau žinių. Sukurtos programos pagrindinė funkcija yra 3D modelio peržiūra ir analizė, tačiau turint reikiamų žinių galima susikurti papildomų funkcijų ir ypatybių, kurios bus reikalingos skirtingiems naudojimo būdams šioje srityje.
