3D modelling of cultural heritage objective in Timisoara using precise LiDAR

Timisoara, the city with most numerous number of historical building from Romania has won the competition for European Cultural Capital in 2021. In this sense there is a complex and important program of rehabilitation of those buildings and also a large program of integrating the historical and geospatial information in webGIS platforms. This fact is in accordance with the European Commission recommendation regarding i2020 an informatics society. The aim of this paper is to present a model of creating 3D objects using laser scan technology (LiDAR) that is one of the most important techniques used to acquire spatial data. It scans quickly the architecture point by point; registers and joints point cloud to digitally simulate the object’s shape; finally, it reconstructs the 3D model accurately. It also produces construction drawing including ichnography, elevation, and cutaway. In addition, detailed structure and vignette can be acquired by close-range photogrammetry method, which produces orthoimages and linear drawings. This method is especially fit for surveying historical architecture that lacks construction records.Timisoara, the city with most numerous number of historical building from Romania has won the competition for European Cultural Capital in 2021.
