magistrsko delo
Povzetek
V zadnjem desetletju je povezovanje bližnjeslikovne fotogrametrije in računalniškega vida
prevzelo vodilno vlogo pri 3D modeliranju objektov. Velik napredek so tako doživela
programska orodja, ki omogočajo pridobivanje prostorskih podatkov iz niza fotografij,
posnetih iz različnih perspektiv. Iz pestrega nabora programskih orodij, ki so danes dostopna
na trgu, smo si za nalogo izbrali program Insight3D, da bi ga preizkusili, ker z njim še
nimamo praktičnih izkušenj. Glavni cilj naloge je spoznati se s programom Insight3D ter
izdelati 3D model izbranega objekta, v četrti ravni podrobnosti (LOD3) po standardu
CityGML. Na začetku naloge so na kratko opisane teoretične osnove, na podlagi katerih
deluje program Insight3D, sledijo navodila za izgradnjo 3D modela, največji del magistrske
naloga pa obsega obdelava fotogrametrično zajetih podatkov ter opis težav, s katerimi smo
se soočili pri uporabi programa Insight3D. Na koncu smo primerjali še tri programska orodja,
ki delujejo po istem principu in so med uporabniki najbolj priljubljena. Geometrično točnost
izdelanega 3D modela smo ocenili na podlagi fotogrametričnih meritev dolžin na izdelanem
3D modelu in geodetskih meritev teh dolžin v naravi.

Using Insight3D to produce a 3D building model |
Sekundarni povzetek: |
The leadership in object 3D modeling was in the past decade taken over by integration of
close range photogrammetry and computer vision. Major progress was achieved in the
development of software tools, which enable obtaining spatial data from series of images
taken from different perspectives. In order to gain new experience, Insight3D application was
chosen to be addressed in this master’s thesis out of the rich set of software tools available
on the market. The main goal of this thesis is to get familiar with the Insight3D application
and to build a 3D model of the selected object in fourth level of detail (LOD3) according to
the CityGML standard. The beginning of the thesis contains a short theoretical background
about the Insight3D application mode of operation, followed by the instructions for building a
3D model. The largest part of the thesis comprises of the photogrammetrically captured data
processing and the description of encountered difficulties while working with the Insight3D
application. Finally, we compared three software tools that work according to the same
principles and are the most popular among the users. Geometric accuracy of the 3D model
was evaluated based on the photogrammetrically built 3D model and geodetic lines
measurements. |
