Analysis of Point Density and 3D Mesh Geometry in the Gebouw Van Padangsche Spaarbank Building

Abstract

Cultural heritage archiving by collecting and managing archives that include documents, archiving using the Close Range Photogrammetry method by analyzing point density and creating a 3D model of the Gebouw Van Padangsche Spaarbank building by taking overlapping photo data from different camera angles. The aim of this research is to analyze point density and 3D mesh geometry to create archives, increasing efficiency in information management. In this research, the results were obtained from 3D modeling of the Gebouw Van Padangsche Spaarbank building using the close range photogrammetry technique, which resulted in 157 photos being used to create the 3D model. The flying height of the drone is no more than 20 m with the height of each line being different, for Line 1 which is on the top line at a height of 17 m, Line 2 at a height of 10 m, Line 3 at a height of 7 m and for Line 4 at a height of 3m The results obtained from this analysis were a total of 94,869 tie points from 144,764 results, 15,393,722 dense clouds, and 529,237 faces. The results of the comparative calculation of the 3D model building dimension accuracy test against the actual size in the field produce an average distance of 0.1408 m.
