Preservation of cultural heritage is an important aspect of the activities of every country, and modern technologies play an important role here. In this research paper, we will consider the synthesis of traditional and modern methods of researching architectural and historical objects on the example of the oldest sacred sites in Lviv.
The study examines the methods of photogrammetry, laser scanning of buildings and their combination, which allows achieving high accuracy and speed in conducting field surveys of objects. An important aspect of the use of modern methods of object fixation is the ability to obtain data on the state of the object in a short period of time, including even camera work to process the collected materials. The advantage of using photogrammetry is the quick creation of a color map and a fairly detailed building volume, but not enough to make accurate architectural drawings. However, this fixation gives a clear understanding of the loss of color in the plaster, the presence of biological damage and other damage. The advantages of laser scanning are, first of all, its accuracy, which allows for detailed measurement drawings. Therefore, the combination of these two approaches and their combination allows to achieve the best result.
