Laserové skenování Duaptahovy skalní hrobky v jižním Abúsíru.

Laser scanning, one of the non-contact methods of aerial data collection, has recently been introduced to the field of archaeological documentation. Its advantages are, above all, speed, accuracy and the volume of acquired data – so called point clouds. The scanners can perform documentation of hardly accessible or dangerous places on site where traditional methods fail. The disadvantages of point clouds processing include the need for high-performance hardware and specialised software, as a great mass of data is usually processed. The article deals with the documentation of Duaptah’s rock-cut tomb at Abusir South by terrestrial laser scanner Faro Focus3D, the methodology of data collection in the field and its subsequent processing and practical outputs (creation of sections, tomb volume calculation, etc.). Such analyses require the presence of an archaeologist who knows the terrain and can define individual tasks during the data processing, for instance the number of horizontal and vertical sections to be carried out, the distance between sections, and the volume of separate parts of tombs (serdab).
