The method detected the reoccurring components of the structures, and then the iterative closest points (ICPs) algorithm is used to verify the results. detected the symmetry from point clouds by analyzing a graph of surface features obtained by a randomized subgraph searching algorithm based on the random sample consensus (RANSAC). Due to the high-density point clouds, which could be up to scales of a billion points, the symmetries of buildings or other 3D objects have been investigated intensively during the past decade. Using point clouds for the digitalization of historical sites and buildings is now very common for cultural heritage because the increased availability of the affordable sensors, data collection platforms (e.g., the unmanned aerial vehicle (UAV)), and the associated processing algorithms. These points are known as the point clouds. The symmetry can be investigated by first applying the state-of-art laser scanning or the digital photogrammetry to record the pagoda structures in terms of tremendous number of points in a three-dimensional (3D) coordinate system. On the other hand, structural health of historical building in terms of symmetry is becoming more and more important for cultural heritage and tourism. Therefore, investigating the pagodas’ symmetry or asymmetry is an essential process for both cultural studies. According to Lu, symmetry in architecture has been found in official documents created during the Warring States Period (BC 770–BC 221) in China. Most of these polygonal pagodas were built with symmetries (both reflectional and rotational) due to the oriental cultural background. The concept presented in the paper not only work for polygonal pagodas, but it can also be readily transformed and implemented for other applications for other pagoda-like objects such as transmission towers.Īncient polygonal pagodas are important components of architectural and historical studies in many oriental countries. This concludes that the examined pagodas are highly symmetric, both rotationally and reflectionally. The results show that there are RMSEs of 5.04 cm and 5.20 cm deviated from the perfect (theoretical) rotational and reflectional symmetries, respectively. The symmetry was realized by rotating and reflecting the pagodas’ point clouds after a complete leveling of the point cloud was achieved using the estimated central axes. The results indicate that the models fit accurately to the pagodas’ point clouds. The method was verified by four datasets collected by an unmanned aerial vehicle (UAV) and a hand-held digital camera. The geometric model consists of multiple polygonal pyramid/prism models but has a common central axis.

In this paper, we propose a new method to investigate both the rotational and reflectional symmetry of such polygonal pagodas through developing novel geometric models to fit to the 3D point clouds obtained from photogrammetric reconstruction. They are usually polygonal structures comprised by multiple floors, which are separated by eaves.

I'm not certain how to accomplish this, and I can't understand how to apply some existing roof tutorials to this issue.Ancient pagodas are usually parts of hot tourist spots in many oriental countries due to their unique historical backgrounds. I am looking at a lot of home designs with a pyramid or cone roof. I've usually been able to find an answer without posting, but I'm stuck on this one.
