Photogrammetry is currently one of the most popular digital methods used in archaeological documentation. Based only on digital pictures it gives us results comparable to laser scanning. Years of experience with photogrammetry combined with powerful software give us the ability to take this method to the highest level and allows us to use it in any environment.

Aerial Photogrammetry

One of the biggest benefits of using photogrammetric method is the ability to create orthophotographic images. Those images lack the perspective errors and they can be used as a base for maps and plans of research areas. Photos of landscapes allow us to create 3D area models. This 3-dimensional data gained from photogrammetry can be much more precise than LIDAR scanning and allows us to create high quality hypsometric maps. We also use aerial photogrammetry to document large scale excavations.

 

 

 

Object Photogrammetry

Photogrammetry at Digital Archaeology is used on a great variety of objects to create highly detailed 3-dimensional models of archaeological remains. Those models can be used for animations, web presentations or 3D printing, but more importantly they are a perfect base for traditional 2D documentation. In most cases we need much less time to collect images for photogrammetry than the amount of time needed to perform traditional documentation of an object. For archaeological remains located in situ we create models with georeferences. If photogrammetry was performed in different phases of object exploration, then we can match the georeferenced models perfectly. Small ceramic vessels, graves, wooden constructions or even whole buildings – for Digital Archaeology there are no objects too big or too small to use photogrammetry.

 

Underwater Photogrammetry

Benefits of photogrammetric method are most noticeable in underwater environment where the amount of time spent on the documentation is of high importance. Our first attempts to use this kind of documentation at underwater sites date back to 2012. Since then we developed methods that let us use photogrammetry on any underwater site, even with poor visibility conditions. We create detailed orthophotographic images of objects that normaly could not be captured on a single photo because of water visibility. For most people underwater cultural heritage is completely inaccessible. That is why the ability to create digital exhibitions containing 3D models of sunken archaeological objects is another great benefit of underwater photogrammetry.
