3D Reconstruction and Accuracy Analysis of Historical Relief Models

چکیده

The relief of Franz Ludwig Pfyffer, constructed between 1762 and 1786, is considered the world’s oldest large landscape model and a pioneering work of Swiss cartography. Based on Pfyffer’s own measurements, the 26 m big work represents topographically an area of almost 4100 km. The relief, which served as a basis for several printed maps issued at the end of the 18th century, is now a subject of the first quantitative evaluation. Applying principles of aerial photogrammetry, a precise 3D model of Pfyffer’s relief is created for the documentation of cultural heritage. As a main research aim, several methods for the comparison of the virtual model with current map information are developed: planar and spatial transformations of identical points and an analysis of digital surface models. Suggested approaches consider object distortions in all three directions and allow making statements about relief accuracy as well as reconstructing Pfyffer’s model building strategy.

Target detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV

In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
