摘要：The following paper describes a method to capture high quality image data for the use of photogrammetric reconstruction techniques. The main principle is to use long focal length to capture immense amount of spatial and radiometric detail. The method was tested at two mediaeval building sites, the Olavinlinna Castle in Savonlinna and the Church of the Holy Cross in Hattula. Long focal length is typically not used in photogrammetry because it results in poor Field of View (FoV) which in turn leads to poor resections because of inadequate geometric quality. Therefore the use of panoramic imaging techniques is proposed to be used together with long focal length to capture both the high spatial and radiometric quality image with wide enough FoV to overcome the geometric problems. The added value is that the photos can be taken from long distance without reducing the amount of detail. In the case of one of our test sites, this is essential because the castle is surrounded by waters. However, the method can also be used for shorter imaging distances if a high amount of detail is desired
