“…A significant advantage of terrestrial laser scanning measurements of a rotary kiln compared to traditional geodetic methods lies in the speed of collecting onsite data, which enables the extraction of various geometric parameters of the rotary kiln from a single dataset. This study presents the determination of the geometric parameters of a rotary kiln using a terrestrial laser scanner (TLS) (Kovanič et al 2020).…”

In the industrial sector, particularly in the cement industry, the key aspect of the production process is the production of clinker through the use of a rotary kiln. Due to the large volume and high temperature involved, these complex structures are subjected to stress and deformation during operation. Therefore, it is crucial to conduct regular control measurements to verify the compliance of the basic geometric parameters. In this article, we examine the literature on various control techniques, with a particular focus on the misalignment of the rotating axis of the ferrule. To measure the rotating axis and ovality of the rotary kiln cylinder, a new data processing method was developed and subsequently implemented. This method was experimentally demonstrated by creating a prototype to validate it, and the results obtained by the prototype were then compared to those obtained by the coordinate measuring machine. The results indicate that the proposed method is effective for determining the real axis of the rotary kiln (eccentricity) and the ovality of the shell structure. With this purpose, the article proposes a new solution for processing spatial data using a mathematical method based on the geometric parameters of the shell structure. This study can be used to develop tools for controlling rotary kilns, particularly in the data collection process.

“…This article presents generally available tools thanks to which it will be possible to widely use the proposed solutions in commercial analyses of deformations in engineering objects. Terrestrial laser scanning (TLS) technology is widely used for the monitoring and determination of surface deformations (Harmening et al, 2021;Yang et al, 2021;Gawronek et al, 2019;Kovanič et al, 2019;Liu et al, 2020). It provides quasi-continuous information about the surveyed surface in the form of a point cloud with X,Y,Z coordinates, complemented by the reflection intensity.…”

Modern measurement technologies are widely used for the monitoring and determination of surface deformations. One more frequently used measurement technology is terrestrial laser scanning (TLS), which provides quasi-continuous information about the tested surface in the form of a point cloud at a given resolution. At the same time, TLS is based on measuring the distance in a given direction, thanks to which we can obtain a high precision of measurement, often compared to tacheometric measurements. This paper presents a study on the determination of surface flatness parameters extracted from a point cloud. It takes into account the roughness characteristics of the different structures on the measured surfaces and analyzes them using the most popular algorithms for determining the distance of points from the reference surface. Additionally, the review presents the issue of expanding selected surfaces onto a plane to analyze their geometric parameters, and thus to determine the deformation. The applied solution can be used to monitor the deformation of objects such as tunnels and interiors of collectors or large-diameter downpipes, the shape of which is similar to a cylinder surface. Thanks to the expansion of the cylinder surface into a plane, it is possible to perform a comprehensive analysis of surface deformation, and not only selected fragments in the form of sections. The conducted analyses show the great potential of data obtained using terrestrial laser scanning, when an appropriate procedure and data processing method are applied. This paper focuses on two types of studies; the study of surface flatness and analysis of the deformation of cylindrical surfaces. These types of studies are extremely useful in assessing the technical condition of structures, especially in studying the deformation of structures built underground (tunnels, passages, warehouses), where the loads from the surrounding earth are significant.

“…This means, that during the scanning process, only some basic parameters (field of view and scan density) are needed to set up and the whole measurement is performed in an automated way. Therefore, TLS is used for different surveying jobs, e.g., [10][11][12][13][14][15][16][17][18][19]. Its main benefit is the efficiency of the 3D data collection (up to 2 million points per second), meaning less time spent on the construction site (needed for measurement) and often a huge amount of data defining the geometry of the surface of the measured structure [20].…”

Wall Structure Geometry Verification Using TLS Data and BIM Model

et al. 2021

Building information modeling (BIM) represents significant progress in the field of digitalization and informatization of the construction process. The virtual model (BIM model) is the source of graphic data among other information, which are applicable for geometry verification of the building’s structures. For this purpose, data and information about the building should be collected. Comparison of the BIM model (design) with as-built 3D models enables the evaluation of the quality of the as-built structures. The most effective methods for spatial data collection are terrestrial laser scanning (TLS) and close-range photogrammetry. Using both methods, measurement can result in a point cloud. The paper describes an approach for verifying the geometry of wall structures. The graphic data of designed structures are represented by the existing BIM model. The approach presented uses the Industry Foundation Classes (IFC) file format from which the designed geometry is derived. The as-built models of the structures are created from point clouds. Point cloud segmentation uses a combination of regression, filtering based on local normal vectors, and curve segmentation. Consequently, the designed and the as-built models (segmented from the point cloud) are compared.
