Positional accuracy in close-range photogrammetry through Topography and Geodesy

open access: yesRevista de Arquitectura (Bogotá), 2023
Computational three-dimensional modelling can be used to reconstruct real-world objects with all their details and conservation conditions. Photogrammetry offers products with accuracy, in addition to the flexibility of execution of simple and complex projects, according to the simplicity and speed in data acquisition.
