Creation and analysis of 3d models based on uav images

Abstract

Glavni fokus rada je izrada, vizualizacija i analiza kvaliteta 3D modela dobijenih iz snimaka bespilotnih letelica - UAV (Unmanned Aerial Vehicle). Analiza prikaza i kvaliteta 3D modela ukljueuje stepen odstupanja geometrijskih karakteristika objekata u različitim modelima i formatima, odnosno u softverskim okruženjima. Proces prikupljanja i obrade podataka je opisan pa fazama, kao i njihova naknadna vizualizacija u dva različita softverska okruženja - Agisoft Metashape i Pix4Dmapper. Kao rezultat obrade u datim softverima, dobijeni su digitalni model visina (DMV) i digitalni model povdi (DMP). Analiza i poređenje kvaliteta obavljeni su kreiranjem aplikacije GUI (graphical user interface) kroz interakciju grafičkih i tekstualnih podataka u programskom paketu MatLAB.

The main focus of the paper is the creating, visualization and analysis of the quality of 3D models obtained from images of Unmanned Aerial Vehicles (UAV). The analysis of the display and quality of 3D models includes the degree of deviation of the geometric characteristics of objects in different models and formats, ie in software environments. The process of data collection and processing is described in stages, as well as their subsequent visualization in two different software solutions - Agisoft Metashape and Pix4Dmapper. As a result of processing in the given software, digital elevation models (DEM) and digital surface model (DSM) were obtained. Quality analysis and comparison were performed by creating a GUI application (graphical user interface) through the interaction of graphic and textual data in the MatLAB software package.
