Αutomatic generation of 3D models using photogrammetry

A major part of the V4Design project is the automatic generation of 3D models using photogrammetry.
Detection and localization of objects, such as buildings, in video and image material was shown in a previous post.
This data is used during 3D reconstruction to segment relevant from irrelevant material, providing a cleaner model to work with.
However, this is not where our work ends. For specific cases, such as buildings, we implement additional segmentation on a 3D level.
This video shows the segmentation of a photogrammetric mesh into building components, a crucial step towards the generation of BIM.
