The idea for ArchEyeAutomatic came from the previous projects and their flaws. After the experiences combining ArchEye and Structure-From-Motion to create 3-D models of buildings it was obvious, that the existing methods are difficult for large and complex sites. The possibility to check for data quality and the completeness of the model are missing within this, it can only recognized by computing the whole project, which can take from several hours to a few days, depending on the number of photos and the computer.
Additionally the approaches for the trajectory-calculation for two dimensional image mosaics within the ArchEye software showed some problems coming from the simplified assumption of horizontal (excavation) areas to document. If the area to document is situated on a hill, the calculations go wrong because the distance from the UAV to the ground is getting shorter if the hill is ascending, therefore the overlaps of the photo series are incorrect. This can lead to gaps in the photo mosaic.
Therefore it is necessary to increase from two to three dimensions and also include more automation. The main focus though is to include the model quality in the algorithms for the automated flight computation.
The project is intending to do an automated documentation of historic buildings for Building Archaeology.
