One of the services we offer is photogrammetry. Here, various photogrammetric methods are used to create a point cloud from a few photos. The point cloud is then meshed. The result is a highly accurate wireframe model on which a texture is placed.
The following video shows the church Wagenitz, which generated a point cloud of almost 2 billion points and a wireframe model of about 4 million polygons with the help of more than 900 images.
Unfortunately, you cannot see the high accuracy with which such a model was created in a video. Therefore, the church of Jühnsdorf can be examined more closely via WebGL in the following.
Once the model has been calculated, high-resolution orthophotos can be created. Like for example here in Goslar of the tympanum.
