Abstract

Stalni napredak i poboljšanje kvalitete snimaka, razvoj naprednih algoritama obrade aerosnimaka, poboljšanje snage i kapaciteta računala, pružaju još veće mogućnosti njihove upotrebe pri izmjeri šuma. U ovom diplomskom radu prikazati će se cjelokupni postupak obrade kao i analize 3D podataka dobivenih iz aerofotogrametrijskog snimanja područja Grada Zagreba, kao i izrada DTM i DSM osnovnih derivata iz stereoskopskog aerosnimanja. Za područje istraživanja određen je Grad Zagreba, konkretno Park Ribnjak, Trg kralja Petra Svačića i Trg kralja Tomislava. Za fotogrametrijsku izmjeru korištene su digitalne kolorne i infracrvene kolorne (ICK) stereo aerosnimke iz 2012. godine, te trodimenzionalni (3D) vektorski podaci na temelju kojih je izrađen digitalni model reljefa (DMR). U diplomskom radu su prikazane mogućnosti primjene 3D podataka iz aerofotogrametrijskog snimanja za potrebe praćenja i inventure urbanih područja. Glavni produkti dobiveni aerofotogrametrijskim snimanjem su izrađen DMT - digitalni model terena i DMP – digitalni model površina, koji nam omogućuju na brz i efikasan način prikupljanje podataka o visini, širini krošnje, površini krošnje pojedinačnog stabla. Na temelju obrađenih aerofotogrametrijskih snimaka područja istraživanja razvidno je da nam svi dobiveni produkti (3D oblaci točaka, DMT I DMP) omogućuju izmjera samo gornje etaže unutar neke sklopljene sastojine ili šume, ali za potrebe praćenja stanja stabala i vegetacije urbanih područja daje korisne i vrlo precizne podatke. Rezultati ovog istraživanja ukazuju na neke od mogućosti upotrebe 3D podataka dobivenih metodama daljinskih istraživanja, te otvaraju nove mogućnosti u analizama i interpretaciji funkcija urbanih šuma i parkova.

Abstract (english)

Continuous progress and improving of images quality, development of advanced algorithms for aerospace processing, improving of power and PC capabilities, provide even greater opportunities for their use in forest measurements. In this graduate thesis will be presented the entire processing procedure as well as the analysis of 3D data obtained from the aero-photogrammetric surveying of the City of Zagreb, as well as the production of DTM and DSM basic stereoscopic aerosol derivatives. As the area of research, was defined the City of Zagreb, specifically Park Ribnjak, Trg kralja Petra Svačića and Trg kralja Tomislava. For photogrammetric measurements were used the digital color and infrared color (ICK)
stereo aerial images from 2012, and three-dimensional (3D) vector data, based on which a digital relief model (DMR) was developed. The graduate thesis presents the possibilities of using 3D data from aero - photogrammetric surveys for the purposes of monitoring and inventory of urban areas. The aerial photography obtained the DMT - digital terrain model and DMP – digital surface model, which enable us to collect data of tree heights on a fast and efficient way, as well as the width of the crown and the surface of the crown of an individual tree. Based on the aero-photogrammetric surveys of the field of investigation, it is clear that all the products obtained (3D point clouds, DMTs and DMPs) allow only the upper floors to be
surveyed within an assembled stand or forest, but for the purposes of monitoring the tree condition and urban vegetation it gives us useful and very precise files. The results of this research are pointing to some of the possible uses of 3D data obtained by remote sensing methods and open up new possibilities in analyzing and interpreting the functions of urban forests and parks.
