Beja Entabulare by ARCHMAT Students

The subject of this photogrammetry model is the partial remains of a roman entablature which can be found at the Igreja de Santa Maria in modern day Beja amongst a collection of Roman period architectural pieces. This piece in particular is a small part of a the architrave, which has been removed from its original context and can be found mounted to the church. A mirrorless compact system camera was utilised to obtain photographs of the capital at three different levels in order to capture every angle of the object. All camera settings were adjusted for the shaded environment in which the capital was housed. Each image taken had a two-third overlap with the preceding image to allow the software to identify overlapping points. To obtain images from other angles the camera was turned first 90° degrees to the right for the images taken at an overhead angle and then 270° to the right for the images taken from below. All of these images were then uploaded and processed through the Agisoft Metashape software.
