We focus on the correction of the measured exterior orientation parameters of the IR camera mounted on a mobile platform. The developed method is based on point-to-point matching of the features extractedfrom IR images with a wire-frame building model. Firstly, the extraction of different feature types is studied on a sample IR image; Förstner and intersection points are chosen for a representation of the image features. Secondly, the three-dimensional (3D) building model is projected into each frame of the IR video sequence using orientation parameters; only coarse exterior orientation parameters are known. Then the automatic co-registration of a 3D building model projection into the image sequence withimage features is carried out. The matching of a model and extracted features is applied iteratively, and exterior orientation parameters are adjusted with least square adjustment. The method is tested on a dataset of a dense urban area. Finally, an evaluation of the developed method is presented with five quality parameters, i.e. efficiency of the method, completeness and correctness of matching and extraction"},{"@xml:lang":"sl","#text":"Namen naše raziskave je samodejna določitev tekstur streh in fasad stavb z infrardečih (IR) posnetkov za teksturiranje obstoječega trirazsežnega (3D) modela stavb. Za to je treba izboljšati natančnosti neposredno izmerjenih parametrov zunanje orientacije IR-kamere, pritrjene na mobilno platformo. Ta prispevek opisuje metodo, razvito za izboljšanje parametrov zunanje orientacije, ki temelji na ujemanju točk samodejno zaznanih grafičnih gradnikov z IR-videoposnetka in žičnega modela stavb. Najprej proučimo zaznavorazličnih tipov grafičnih gradnikov na testnem IR-posnetku. Förstnerjeve in presečiščne točke izberemo kot primerne grafične gradnike za predstavitev obravnavanih značilnosti stavb na IR-posnetku. 3D-model stavb projiciramo na vsak posamezen posnetek videosekvence ob upoštevanju orientacijskih parametrov, od katerih so parametri zunanje orientacije podani s približnimi vrednostmi. Nato izvedemo samodejno koregistracijo 3D-modela stavb, projiciranega na videoposnetek, in grafičnih gradnikov, zaznanih z istega IR-videoposnetka. Samodejno ujemanje 3D-modela stavb in zaznanih grafičnih gradnikov poteka iterativno in skupaj z izravnavo parametrov zunanjeorientacije z metodo najmanjših kvadratov. Razvito metodologijo za koregistracijo in izravnavo zunanjih orientacijskih parametrov smo preizkusilina strnjenem poseljenem območju. Kakovost metodologije ocenimo s petimi parametri: učinkovitostjo metodologije, popolnostjo in pravilnostjo algoritmov za ujemanje in zaznavo grafičnih gradnikov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-LJUMJZ36","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-LJUMJZ36"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-LJUMJZ36/9834ab7c-9d06-44cb-8c17-cbbe1d5c0f9f/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Zveza geodetov Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-LJUMJZ36/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-LJUMJZ36"}}}}
