Wykorzystanie danych skaningu laserowego do modelowania 3D fortów obronnych na przykładzie Fortu Prusy w Nysie

Laser scanning data, both airborne and terrestrial, are increasingly being used for 3D modeling. This is a particularly effective measurement technology for historic fortresses that are a combination of stone and earthen structures and that are usually covered by dense vegetation. This paper presents a methodology for constructing a realistic 3D model using the example of the Prussian Fortress in Nysa. The data used for modeling were collected by airborne and terrestrial laser scanning and supplemented with digital photos. Scanning was performed with a resolution of 12 points per m2 for the airborne platform and about 2 cm for the terrestrial one. The steps and requirements involved in modeling are presented in detail. The algorithms and software that were developed for this work highlight the potential that would be available by automating this process. The specifics of the model are discussed for this type of military structure on a combination of airborne and terrestrial laser scanning data. The issues of the level of detail and accuracy of the modeling are discussed, while emphasizing the opportunities for the use of laser scanning in landscape architecture.
