“…Therefore, this application is not used except in compulsory cases. Instead, scanning is performed from more than one point (Senol et al, 2017;Senol et al, 2020). In this study, scanning was not carried out from a single point, the scans were carried out at more than one station point.…”

Forest management plan TLS Point cloud 3D modelStudies in forestry in Turkey have great importance between humanity and life. In this direction, many forestry studies are carried out. The purpose of these studies is to protect forest areas and to ensure their continuity. The forestry organization continues to work urgently in line with this purpose. As a result of the researches, it is seen that old methods are lacking in time and cost in the forest management plan and many forestry studies. Nowadays, researches have been made on the use of the old methods, the use of terrestrial laser technology, which is seen as costly but actually offers positive opportunities at a low cost in line with the purpose to be used. In this study, how the methods used in forest management plans can contribute to the forestry sector with terrestrial laser scanning, which is one of today's technologies, and the sensitivity of devices and software that can be used in this direction are scrutinized. The data obtained as a result of the study were compared with the old methods and the usability of the terrestrial laser scanning method was examined.

“…In addition, the historical sites as related in ref. [41] are hot topics in archaeological engineering and their safety are of great importance. However, they suffer from aging effects, geo-hazards, urban construction, etc., thus it is necessary to analyze and detect changes from these structures.…”

Extracting Individual Bricks from a Laser Scan Point Cloud of an Unorganized Pile of Bricks

et al. 2018

Bricks are the vital component of most masonry structures. Their maintenance is critical to the protection of masonry buildings. Terrestrial Light Detection and Ranging (TLidar) systems provide massive point cloud data in an accurate and fast way. TLidar enables us to sample and store the state of a brick surface in a practical way. This article aims to extract individual bricks from an unorganized pile of bricks sampled by a dense point cloud. The method automatically segments and models the individual bricks. The methodology is divided into five main steps: Filter needless points, brick boundary points removal, coarse segmentation using 3D component analysis, planar segmentation and grouping, and brick reconstruction. A novel voting scheme is used to segment the planar patches in an effective way. Brick reconstruction is based on the geometry of single brick and its corresponding nominal size (length, width and height). The number of bricks reconstructed is around 75%. An accuracy assessment is performed by comparing 3D coordinates of the reconstructed vertices to the manually picked vertices. The standard deviations of differences along x, y and z axes are 4.55 mm, 4.53 mm and 4.60 mm, respectively. The comparison results indicate that the accuracy of reconstruction based on the introduced methodology is high and reliable. The work presented in this paper provides a theoretical basis and reference for large scene applications in brick-like structures. Meanwhile, the high-accuracy brick reconstruction lays the foundation for further brick displacement estimation.

“…Remote sensing methods play an important role in the detection and preservation of existing and buried archaeological artifacts [3]. The results obtained from these studies can be used for archaeological projects as well as for the documentation of excavation sites [4]. While achieving this process, where the structure needs to be reconstructed the geometric accuracy of the model obtained is important [5,6].…”
