Történelmi épületek rekonstrukciós munkálatainak támogatása pontfelhők segítségével

Architects ordered the complex building survey of the Royal Castle of Esztergom and generating architectural products like floor plans, cross sections and orthoviews of the walls to support reconstruction works. Due to certain specialities of the castle like extension of the walls (both vertical and horizontal), fragmented and irregular surfaces, dark rooms inside, we decided to use laser scanning technology combined with Unmanned Aerial System (UAS) photogrammetry for surveying. Latter was used outside the building and GNSS measurements ensured merging the point clouds from the different sources together. Current paper presents how the mentioned architectural products were derived from point clouds and discusses how efficiently laser scanned data and point cloud derived from UAV could be used.
