“…After comparing traditional and automated methods of determining ground coordinates, it was discovered that there were notable discrepancies in both the final values and the time taken to determine coordinate points. Previous research exploring comparative deviation analysis, focused on creating point clouds via laser and digital photogrammetry, is discussed in [9]. The accuracy of point positioning by computer programs is analyzed in [10], where the coordinates of points obtained through tachymetric survey are used as the reference system by the authors.…”

Engineers are currently facing questions about the use of geographic information systems or software to implement projects in a short time. The problem with using geographic information systems in construction is the relevance of the available data. An example is open sources with satellite images. This problem appeared even before satellite-positioning systems emerged. In this connection, the purpose of this article is to find the deviation of source points when performing photogrammetry with marker detection in Agisoft PhotoScan software. This method of determining coordinates using a single point and its correlation on the ground is applicable in the case of rapid calculations, where the volumes of earth masses are large enough and do not require increased accuracy at the stage of approximate calculations. As a result of the comparison of traditional and automated methods of definition of coordinates on the ground has been found an essential distinction, both in total values and in time spent for the definition of points of coordinates. The considerable difference revealed by the results of the comparison of coordinates is presented in the table as a color gradation. The average deviation between known coordinates and coordinates obtained in Agisoft PhotoScan by axes was: X=0.87%, Y=0.45%, Z=0.12%.

“…Among them, many studies using laser scanner with high precision are found [30][31][32]. In addition to laser scanning, technologies such as photogrammetry [33,34], multi-light imaging [35], and airborne lidar [36] are being applied to reverse engineering. In addition, drone can be applied to various fields such as construction land surveying, construction logistics management, on-site construction management (e.g., safety management, quality management, time management, site management), construction facilities management, demolition management [37].…”

This study proposed a phased reverse engineering framework to construct cultural heritage archives using laser scanning and a building information model (BIM). This framework includes acquisition of point cloud data through laser scanning. Unlike previous studies, in this study, a standard for authoring BIM data was established through comparative analysis of existing archives and point cloud data, and a method of building valuable BIM data as an information model was proposed. From a short-term perspective, additional archives such as member lists and drawings can be extracted from BIM data built as an information model. In addition, from a long-term perspective, a scenario for using the cultural heritage archive consisting of historical records, point cloud data, and BIM data was presented. These scenarios were verified through a case study. In particular, through the BIM data building and management method, relatively very light BIM data (499 MB) could be built based on point cloud data (more than 917 MB), which is a large amount of data.

“…Even though digital photogrammetry has been applied in various fields such as archeology [15], biology [16], topography [17] and geology [18], only several examples could be found on engineering application, especially for geometrical objects, such as Pelton bucket and turbine blade runner [19]. It could be due to the uncertainty on the accuracy of such method [20]. Thus, it is important to investigate the feasibility and reliability of the makeshift 3D scanning method based on the photogrammetry technique.…”

A three-dimension (3D) scanner is one of the important tools for digital reproduction of physical objects in reverse engineering. In some cases, a makeshift 3D scanner is needed immediately, such as for emergency spare parts reproduction. Thus, this research aims to investigate the feasibility of a low-cost makeshift 3D scanner using a mobile phone and the photogrammetry method in reconstructing digital 3D models of geometrical objects. A focus is given to the dimension accuracy of the reconstructed 3D models, which have been reproduced using images taken by a mobile phone, in comparison with the actual dimension of the scanned test pieces. To do so, four types of actual geometrical test pieces with dimension from 5 to 175 mm had been fabricated using CNC machine. 3D models of each test pieces had been developed using the photogrammetry method and compared with those developed using an industrial-grade high-end 3D scanner. It was found that mobile photogrammetry achieved an average accuracy of 97.2%, with minimum and maximum values of 83.3% and 99.9%, respectively. Geometrical dimensions less than 10 mm tend to have lower accuracy, while it was the opposite for dimensions over 150 mm. Furthermore, the scanning limit for either method was found to be a surface with a small tilting angle (less than 3 degrees). Nevertheless, photogrammetry method in combination with a mobile phone has the potential to be utilized as an alternative of a makeshift 3D scanning system with sufficient accuracy using commonly available tools.
