Abstract

Osnovno orodje v fotogrametriji so profesionalni merski fotoaparati, ki imajo poznane (kalibrirane) parametre notranje orientacije in stabilno konstrukcijo. Zaradi vedno večje kakovosti in nižje cene pa se za določene fotogrametrične namene vse bolj uveljavlja uporaba nemerskih (amaterskih) digitalnih fotoaparatov, kjer je potrebno parametre notranje orientacije določiti v postopku kalibracije. V okviru diplomske naloge je bila izvedena kalibracija nemerskega digitalnega fotoaparata Nikon D70 na testnem polju, ki je vzpostavljeno v kletnih prostorih UL Fakultete za gradbeništvo in geodezijo. Testno polje predstavljajo prostorsko razporejene in ustrezno signalizirane točke, katerih prostorske koordinate so bile predhodno določene s klasično metodo izmere. Parametre notranje orientacije smo najprej želeli določiti z metodo samokalibracije v okviru izravnave aerotriangulacije. Med obdelavo so se pri izvedbi te naloge pokazale težave v izbranem programskem paketu AeroSys, zato smo praktično izvedbo prilagodili programski opremi (parametre notranje orientacije smo določili z direktno linearno transformacijo). Rezultati so pokazali, da z uporabljenim postopkom in opremo lahko dosežemo natančnost fotogrametrično določenih prostorskih koordinat nekaj cm, kar je sprejemljivo za določene manj zahtevne naloge bližnjeslikovne fotogrametrije.

Secondary title: Calibration of a digital camera on a test field
Secondary abstract: The principal tools of photogrammetry are professional cameras with calibrated parameters of inner orientation and stable construction. However, due to increased quality and lower prices, the use of amateur digital cameras, where the parameters of inner orientation are determined during calibration, for certain photogrammetric purposes is growing. For the aim of this diploma thesis, the calibration of Nikon D70 digital camera was performed at the test area in the basement facilities of the Faculty of Civil and Geodetic Engineering, University of Ljubljana. The area consists of spatially located and properly identified points with spatial coordinates previously determined via the classic measurement method. The initial aim was to determine the parameters of inner orientation through the method of self-calibration within the compensation of aerotriangulation. During data analysis certain problems with the chosen software package AeroSys became evident, so the practical implementation was adjusted to the software capabilities (the parameters of inner orientation were determined by direct linear transformation). The results have shown that by using the described procedure and equipment, the accuracy to within several centimetres of photogrammetrically determined spatial coordinates can be achieved, which is acceptable for certain less demanding tasks of close-range photogrammetry.
