Abstract
V magistrskem delu smo naredili pregled in oceno metod zajema geometričnih podatkov zunanjosti stavb za program epiqr® in 3D prikaz. V prvem, teoretičnem delu, smo naredili pregled obstoječih prostorskih podatkov, ki omogočajo pridobitev geometričnih podatkov zunanjosti obstoječih stavb. Naredili smo pregled obstoječih tehnologij in metod zajema, ki omogočajo določitev geometričnih podatkov in izdelavo 3D modela zunanjosti stavb. Te tehnologije in metode smo med seboj primerjali ter jih ovrednotili z vidika metodologije epiqr®. Kot rezultat teoretičnega dela smo predlagali 5 različnih metod za določitev geometričnih podatkov in izdelave 3D modela zunanjosti stavb. V drugem, praktičnem delu, smo predlagane metode preizkusili na treh testnih stavbah, ki se razlikujejo v velikosti, kompleksnosti geometrije in prisotnosti ovir, ki lahko otežijo zajem podatkov na terenu. Praktični preizkus je v odvisnosti od metode obsegal pridobitev obstoječih podatkov, načrtovanje in izvedbo dela na terenu (meritve in zajem podatkov zunanjosti stavb), obdelavo podatkov, izdelavo 3D modela in določitev geometričnih podatkov zunanjosti stavb, pri tem pa smo beležili porabljen čas za dokončanje posameznih faz. Predlagane metode smo ovrednotili glede na geometrično natančnost, časovno potratnost in dodano vrednost. Pri tem smo geometrično natančnost predlaganih metod ocenili na osnovi izračunanih odstopanj geometričnih podatkov zunanjosti testnih stavb, pridobljenih v sklopu praktičnih preizkusov predlaganih metod, z referenčnimi vrednostmi geometričnih podatkov zunanjosti testnih stavb, ki smo jih določili s klasično metodo izmere karakterističnih točk stavb. Na osnovi pridobljenih rezultatov smo ocenili primernost predlaganih metod za namen programa epiqr® in 3D prikaz.

Title:Review and assessment of methods for geometric data acquisition of buildings envelope for program epiqr® and 3D visualization
Abstract:
Master’s thesis presents review and assessment of methods for geometric data acquisition of buildings envelope for program epiqr® and 3D visualization. First, theoretical part, of the thesis is an overview of existing spatial data, which could be used in order to extract geometric data of building’s envelope and an overview of existing technologies and methods for geometric data acquisition and 3D modeling. These technologies and methods are compared and evaluated according to epiqr® methodology. As a result of theoretical part, 5 different approaches for geometric data acquisition and 3D modeling of building’s envelope are proposed. Second, practical part, of the thesis describes practical tests of proposed approaches. These were tested on 3 test buildings, which differ in size, shape and surrounding occlusions, which might prevent data acquisition. Depending on the used approach, tests included existing spatial data collection, planning and execution of on-site surveying, processing of obtained data, 3D modeling and determination of geometric data of building’s envelope. Within each test, the time spent to finish individual phase has been measured. Proposed approaches are evaluated from the perspective of geometrical accuracy, time, effort and added value. Geometrical accuracy is determined based on comparison of geometrical data obtained using proposed approaches and high accuracy reference measurements. Based on the experiment results, suitability of proposed approaches for epiqr® program and 3D visualization is given.

Keywords:epiqr®, photogrammetry, modeling, envelope geometry, 3D model
