Production of High Geometric Resolution Orthophotos by Photogrammetric Approach for the Royal Racconigi Castel Park Documentation

Abstract

The aim of this work concerns the development of a simple and rigorous procedure for the construction of metric orthophotos in high geometric resolution and rich in detail through the use of terrestrial and UAV photogrammetry techniques. This approach has been tested on various datasets relating to the Racconigi Castle (Italy) and has allowed the state of the sites to be documented. All the orthophotos produced made it possible to identify the critical areas from a conservation point of view and, at the same time, to create a support tool that makes it possible to identify, with high precision, the damaged areas in a short time thanks to the georeferencing of the processed models.

Uav Photogrammetry as a Multidisciplinary Approach in Engineering Design and Sustainable Land Management

“…black and white or yellow and black); their size varies according to the Ground Sample Distance (G.S.D.) value and consequently according to the flight altitude of the UAV (Alfio et al, 2023). In addition, each UAV device may have its own integrated camera so that, depending on the sensor, the GSD value must be established at the survey planning stage, which will then adjust the maximum attainable flight height (Pepe et al, 2018).…”
