Project Description

Archaeovision was commissioned to conduct a large scale building survey and documentation project at the Church of Our Lady of Kazan in Tallinn, Estonia.

The Kaasan Church was built during the time of Peter the Great (1721) and is the oldest wooden sacral building in Tallinn. One of the aims of the recording was to record the current situation of the building including the structures, interiors and exterior.

The church is small but is very complex. The places which are not accessible with the laser scanner were recorded using a photogrammetric survey. The end result of this was a point cloud and a meshed model, with the additional benefit of having a high resolution texture for photo-realistic visualisations. With both types of recording taking place, the combination of the the data allowed for a precise and accurate representation of the church that goes beyond any form of recording that has previously taken place.

Laser scanning and photogrammetric survey were used for final CAD drawings (plans) overlaid with orthophotos and Building Information Model (BIM).
