The preservation of heritage buildings is essential in a modern society that understands the importance of architecture, culture, and history. The lack of reconstruction funds or the vision of the decision-makers can delay the realization of the works to protect these buildings. The digital conservation of these buildings can be a solution for a later reconstruction or for the creation of a realistic virtual museum. The article presents the rigorous setup and calibration of an airborne side scanner mounted on a UAV platform. Acquiring fine architectural details involves the use of more precise scanning sensors, with substantially higher costs, leading to delays. The present study shows that medium precision scanning sensors can also be used for digitizing architectural details. The side scan solution can be applied successfully in the digital preservation of buildings with a medium degree of detail, but it can also be useful in complex cases. Using optimal processing methods greatly improves the internal accuracy of the modelling with little loss in accuracy. The proposed methodology can be applied even when using superior sensors, leading to exceptional results.
