Comprehensive Comparative Analysis of Photogrammetric Point Cloud Generation Using Diverse Data Collection Methods

Abstract

This study presents a detailed comparison of three data collection tools the Ricoh Theta Z1 360° camera, Leica ScanStation C10 laser scanner, and Matterport PRO 3 mobile scanner for generating photogrammetric point clouds. Conducted in the challenging environment of the Geoinformatics Institute s ground-floor corridor and three additional rooms at Óbuda University, the research evaluates accuracy, compactness, ease of use, survey speed, and processing efficiency. Data processing utilized Agisoft Metashape [1], Autodesk Recap Pro [7], and CloudCompare [5], with measurements validated against a Leica Disto rangefinder. Results show the Leica C10 offers superior accuracy but is hindered by slow survey times and bulkiness, the Matterport PRO 3 balances speed and precision with VR capabilities, and the Ricoh Theta Z1 excels in rapid surveys but lacks precision. These findings guide tool selection for geospatial applications, highlighting trade-offs in accuracy, portability, and efficiency.
