Opis:
Metal foams are new, as yet imperfectly characterized, class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They offer a potential for lightweight structures, for energy absorption, and for thermal management; and at least some of them are cheap. Such characteristics have been appreciated by the automotive industry in the aspect of crash and impact phenomenon. Energy absorption capacity of foams under dynamic load was analytically confirmed based on a rigid-perfectly plastic-locking foam model. In this paper the development process of a real closed cell foam microstructure based on finite element model with the use of SD scanning is shown. Computed tomography (CT) is a medical imaging method employing tomography created by computer processing. Digital geometry processing is used to generale a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The numerical analyses carried out with the usage of LS Dyna computer code of the quasi static and dynamic compression tests are presented. The most important mechanisms and phenomena that appeared in the microstructural sample are described. In the final part of these investigations the comparison process between numerical and experimental test was performed. The results confirmed the good correspondence between both tests.

The stocktaking is the basic form of presenting and protecting the object of the historic ruin. It also allows to monitor the behavior state and the degradation progress of an object. Objects in ruin are very specifi c because they usually do not have elements typical for an existing building. This means that in the case of ruins, methods of stocktaking taken in the same way as in the case of traditional facilities will be insuffi cient. Elements of objects in ruin often have complicated and diverse geometry, diffi cult and not completely secure access to all elements. The article presents methods that can be helpful in the stocktaking of such objects. Each method describes the necessary equipment and instruments, the method of taking measurements, accuracy, advantages, and limitations. The paper also presents examples of application for selected methods

The rapid development of CAD 3D systems has led to the development of solutions enabling the physical achievement of the designed object, already at the design stage. Such a solution is the rapid prototyping method, intended for fast, precise and repeatable production thanks to additive technology. The first basic step of this method is a 3D scan. It is a technique that analyzes a real object in order to collect data about its basic (geometric) and additional (e.g. color) features. The collected data is used to generate three-dimensional, virtual models. Scanning can be performed in various ways using different devices. The aim of the article is to review the available technologies for digitizing 3D objects and to compare them in the context of individual application areas. It presents selected tools and software that will economically and efficiently increase the range of applications of digitization methods in the production process and offering various services on the market.

With the success of the BBC and PBS series such as Italy’s Invisible Cities (2017), Ancient Invisible Cities (2018), and Pompeii: New Secrets Revealed (2016), made in collaboration with ScanLab and employing LiDAR scanning and 3D imaging techniques extensively, popular television programmes grasped the aesthetics of spectral 3D mapping. Visualizing urban topographies previously hidden away from view, these shows put on display technological prowess as means to explore veritably ancient vistas. This article sets out to investigate cinematographic devices and strategies – oscillating between perspectives on built heritage championed by two figures central to the 19th-century discourse on architecture: Eugène Emmanuel Viollet-le-Duc and John Ruskin – manipulating the image in a rivalry for the fullest immersion into a traversable facsimile of past spatialities.
Sukces serii produkcji BBC i PBS zatytułowanych Niewidzialne miasta Włoch (2017), Niewidzialne miasta starożytności (2018) czy Pompeje: Nowe tajemnice ujawnione (2016) jest jednocześnie sukcesem współpracy twórców z grupą ScanLab, która wykorzystuje urządzenia typu LiDAR oraz technologie obrazowania trójwymiarowego do zobrazowania estetyki analizy przestrzennej. Wizualizowanie topografii miejskiej – wraz z jej podziemnymi formacjami, wcześniej niezarejestrowanymi w dokumentacji – stworzyło okazję do eksponowania sposobu działania zaawansowanej techniki w tworzeniu spójnego obrazu przeszłości. Autor koncentruje się na metodzie wizualizowania tych wcześniej niedostępnych przestrzeni oraz na strategiach zanurzania widza w tej reprezentacji/symulacji, a przy tym oscyluje między skrajnymi poglądami na problematykę zachowania/odtwarzania dziedzictwa materialnego, jakie wypracowali Eugène Emmanuel Viollet-le-Duc i John Ruskin.

This article is dedicated to the possibilities of using 3D scanning method for geometric parameter measurements of protective helmets and to the development of methodology for conducting such research. The basic requirements for helmets are related to its geometrical parameters. They are determined in the laboratory during the appropriate tests, and the results are used in the certification process. The method of determining such parameters used to date is based in most cases on the use of head models, linear gauges and calipers. For this reason, a complicated shape of the helmet shell and the construction of the harness pose considerable problems. To avoid such problems, and more importantly measurement errors, the possibility of using modern 3D laser scanning technology to measure the helmet geometry was verified.

Increase of automation and autonomy of production is the latest trend incorporated into Industry 4.0 objectives. Production autonomy is very desirable in the field of damaged parts replacement. To fulfill this goal numerous reverse engineering systems have been developed that support geometry recognition from the 3D scan data. This study is focused on converting non-parametric geometry representation of shaft-type elements into a CAD model with a rebuilt feature tree. Algorithms are based on the analysis of parallel cross-sections. The proposed system is also capable of identification of additional geometric features typical for 2.5 axes milling such as pockets, islands and outer walls. The proposed algorithms are optimized to increase efficiency of the process. Initial identification parameters are selected with respect to defined criteria, e.g., identification accuracy, computing power and scanning accuracy. Described algorithms can be implemented in reverse engineering systems.

Measuring and inspection works in production process using laser scanners attached to the robot manipulators are more and more used in different ways and purposes. The aim of this article is to study and analyze the usage of 3D measuring devices attached to the robot manipulator according to determine the range and the purpose of such industrial measurements. Different scanning devices are applied in production areas with varying purposes, such as 3D scanning of the new product, in order to inspect and find defects. Attached to the robot manipulator, scanners or laser measuring devices are able to scan every object in range of a robot, which makes the measuring process very flexible. Several tests with 3D scanners were performed to find out the optimal conditions and configuration for production purpose. As a result, knowledge base suitable for different production areas was developed. Thus, it would be feasible to have a common database to be implemented in different production areas.

harbour infrastructure
Opis:
In the Polish law harbour infrastructure is one of key elements to determine the various cargo types, available means of transport and, ultimately, the significance of any sea port. The structures, devices and installations situated within a port’s boundaries, dedicated to the swift operation of the port, are all designed for tasks that involve the best use of this infrastructure. The proper development and modernization of this infrastructure may well result in improved cooperation with road networks and transportation on land. Owing to modern technology, it is possible to scan the surrounding buildings or location with great accuracy and render three-dimensional models of the scanned objects. These models can be used to generate harbour maps with a detailed 3D picture of the entire port and navigational infrastructure. The authors of this article present the possible applications of modern laser scanning technology in port infrastructure surveying, and in particular in the survey of a complicated wharf line on the Motława River along Długie Pobrzeże Street in Gdańsk.
Infrastruktura portowa jest ważnym elementem w funkcjonowaniu portu. Co pewien czas należy dokonywać jej inwentaryzacji, aby określić stopień przydatności obiektów do dalszego funkcjonowania. W artykule autorzy przedstawili, jak do tego celu można wykorzystać nowoczesne metody skaningu laserowego 3D. Za pomocą skanera fazowego przeskanowano obiekty znajdujące się nad rzeką Motławą w Gdańsku. Do obróbki danych wykorzystano specjalistyczne oprogramowanie firmy Lica, która wypożyczyła skaner i oprzyrządowanie niezbędne do wykonania skaningu obiektów. Powstała baza danych w postaci chmur punktów, które reprezentują trójwymiarową infrastrukturę nadbrzeżną. Na przygotowany zbiór punktów można nałożyć teksturę i stworzyć modele obiektów 3D, które w dalszym procesie można wykorzystać jako wizualizacje w środowisku symulatorów nawigacyjnych.

Opis:
This paper describes the process of creating a digital model of spiroid gears used in the defense industry. This is where the precise measurement of the parts with the highest requirements for accuracy is of great importance. The construction of a computational model of a physical object was carried out using an optical three-dimensional scanner. Based on the cloud of points obtained in the process of scanning, a spatial digital model reflecting the geometry of an existing element was developed. Polygonization and mesh reconstruction allowed to create a finite element method model that enabled the precise reproduction of the scanned object. The created model was subsequently used to conduct appropriate analysis and simulation to verify the correctness and possible modification of the construction of both elements of spiroid gears: worm thread and face gear

Opis:
During the exploitation screw thruster, lobes are being defected in many ways. Sample types of damages are as follow: the material damages caused by cavitation, corrosion, deflection. In order to facilitate and to improve the quality of repairing activities, the idea of make the position to designate screw thruster lobes specific gravity has been initiated by Rolls-Royce Poland Company and Nautica Academic Circle. Incorrect lobes balance influences on irregular work of the screw, which results in the occurrence of adverse effects such as generation of vibration or increasing probability of mechanical elements damages during the exploitation. Screw thruster lobe specific gravity designation helps in identification of areas for treatment (welding, grinding) to achieve the desired parameters. The creation of designate screw thruster lobes specific gravity position gave the possibility of using the innovative scanning in 3D, which shows very clearly the picture of the scanning item. With Scanect and Autodesk Inventor 2014 software, we can manipulate the resulting image. This makes possibility of the lobes gabarits measurement. What is more, it designates the specific gravity exact to 10%.It increases the quality of the lobe renovation and these results in an improvement the screw thruster lobe’s work efficiency.The cooperation of The Maritime University in Gdynia and Rolls-Royce Poland Company resulted in creating the prototype, which will be tested by service technics in working circumstances.

Opis:
Methodology of analysis of damages of piston combustion engines by using 3D scanner enabling threedimensional analysis of such damages was introduced in the study. The principle of the device operation and his investigative possibilities were introduced. Presented is a phased process of scanning. The possibilities of the method were analyzed on examples of the damaged pistons for this engine supplied by fuel with low octane number. Precision of the damage measurements were estimated. The piston is one of the busiest part of the engine. The effects of wear on its surface are irregular and difficult to quantify. Geometric shape changes are related to: - movement of material in the case of dry friction due to accidents, - loss of material due to burnout, - formation of carbon deposits. With the 3D scanner is possible to observe these processes and to quantify the resulting deformation. The measurement results can be edited in many different ways to connect them to present them in an accessible form. Moreover, data obtained in digital form, you can quickly send long-distance transport instead of the actual object which is costly and time consuming.

Opis:
Modern 3D scanners can measure the geometry with high accuracy and within a short time. In turn, currently produced CNC machine tools allow for very accurate manufacturing; however, processes beyond the machining cycle remain time-consuming. This paper presents the idea and experimental tests of the scanning system in the CNC machine, which allows to speed up on-machine measurements, align clouds of 3D data points with an accuracy close to that of the machine itself, and finally set the workpiece coordinate system for machining. This modern approach is in line with Industry 4.0, combining the terms of data processing, machine vision, manufacturing automation, and human-machine interfaces. The future implementation of the proposed system as an interchangeable tool will allow performing autonomous measurements, inspection, and supervision of the workspace, without engaging the machine operator. The system calibration and experimental results using the industrial 3D scanner and CNC machine are described.
