Abstract (sommario):

The article discusses ways to optimize the performance of information communication systems, which includes increasing spectral efficiency and reliability while minimizing delay and energy consumption due to the full integration of communication and scanning services. The functioning algorithm of the integrated scanning and communication system and the organization scheme of the communication mode using the scanning process based on the proposed generalized model of the integrated scanning and data transmission system are considered. Ways to improve the efficiency of telecommunication systems due to the joint use of communication and scanning tools with the best compromise between scanning characteristics and the bandwidth of the transmission channel are considered. Peculiarities of improving wireless communication systems with regard to high data transfer rates, low latency and wide connection possibilities are studied. In particular, access to other system functions, such as scanning/visualization and localization, is justified. Due to the considered innovative applications, the possibility of increasing the performance of the integrated wireless scanning and communication system (ISAC) is determined. The researched positioning process in 5G is proposed to be expanded due to additional detection functions, in particular with the use of new metrics such as accuracy and resolution. New KPIs in 6G networks are considered, replacing the KPI of positioning accuracy in 5G. As a result, key performance indicators based on different application scenarios are proposed, the accuracy of which should be from 1 to 10 cm, and the resolution should be up to 1 mm. The potential of the new ISAC technology was investigated, in particular, the features of the coexistence of communication and scanning modules in an integrated solution at the system level and methods of increasing the efficiency of coexistence at the system level were considered; justification of a positive result from an integrated system solution for communication and scanning services; advantages and disadvantages of existing communication and scanning systems with implemented integration at the system level. The obtained results of research on the integration of communication and scanning means, in particular: the analysis of the performance of generalized ISAC networks and the conclusions about the fundamental limits of performance obtained for a simple structure made it possible to determine the best compromise between the characteristics of scanning and the bandwidth of the communication channel, provided an opportunity to create practical schemes, which approximate a compromise of waveforms, coding tables, structures and protocols.

Abstract (sommario):

Intraoral scanners (IOSs) are devices used for capturing direct optical impressions in dentistry. IOS eliminates the errors that are encountered with the conventional impression making procedures. The last decade has seen an increasing number of optical IOS devices, and these are based on different technologies. The objective of this review article is to discuss intraoral scanners with regards to its technology, generation systems, scanning paths, necessity of a powdering medium, accuracy (Trueness and precision), intermaxillary relationship registration, commercially available IOS, clinical recommendations, advantages, disadvantages, indications and contraindications. Digital impressions with IOS is likely going to be a routine procedure in dentistry in the near future.

Abstract (sommario):

The rapid development of intelligent microprocessor technology, the availability of global navigation systems (GPS) and inertial imaging units (IMU) with the progress of the creation of a new generation of mobile autonomous systems from a distance This is the concept of autonomous robots and unmanned aerial vehicles. Recently, actively using unmanned aerial vehicles (UAVs) and mobile robots, they are solving the tasks of photogrammetric and laser scanning of the terrain quite quickly. High spatial resolution data collected from available platforms such as satellites and manned aircraft are typically in the range of 20–50 cm/pixel, while UAVs are capable of flying at much lower altitudes and can therefore collect images with a much higher resolution of the image. Mobile robots and UAVs in combination with modern technologies of digital video and photo processing, as well as programs for intelligent image recognition, have gained actual use, both for military tasks and in the civil sphere as a tool for remote sensing of territories and infrastructure high-resolution objects. On the basis of scanned UAV images, 3D models of the terrain can be reproduced. This article deals with the analysis of technical means of mobile scanning of territories and some well-known algorithms for controlling the scanning system.

Abstract (sommario):

In traditional laser-based 3D measurement technology, the width of the laser stripe is uncontrollable and uneven. In addition, speckle noise in the image and the noise caused by mechanical movement may reduce the accuracy of the scanning results. This work proposes a new multiple laser stripe scanning profilometry (MLSSP) based on microelectromechanical systems (MEMS) scanning mirror which can project high quality movable laser stripe. It can implement full-field scanning in a short time and does not need to move the measured object or camera. Compared with the traditional laser stripe, the brightness, width and position of the new multiple laser stripes projected by MEMS scanning mirror can be controlled by programming. In addition, the new laser strip can generate high-quality images and the noise caused by mechanical movement is completely eliminated. The experimental results show that the speckle noise is less and the light intensity distribution is more even. Furthermore, the number of pictures needed to be captured is significantly reduced to 1 / N ( N is the number of multiple laser stripes projected by MEMS scanning mirror) and the measurement efficiency is increased by N times, improving the efficiency and accuracy of 3D measurement.

Abstract (sommario):

Scanning systems have enabled a great deal of change in modern supermarket operations, if not actually causing it. Because of this, cashier and shopper behavior is different in many respects than it was in the days before scanning. The panel will discuss many of the changes observed since the introduction of optical bar code scanning systems and will speculate on future direction. A three factored framework will be used for these discussions; physical design, functional design, and usability design.

Abstract (sommario):

The emergence of hand-held Personal Laser Scanning (H-PLS) systems in recent years resulted in initial research on the possibility of its application in forest inventory, primarily for the estimation of the main tree attributes (e.g. tree detection, stem position, DBH, tree height, etc.). Research knowledge acquired so far can help to direct further research and eventually include H-PLS into operational forest inventory in the future. The main aims of this review are: - to present the current state of the art for H-PLS systems - briefly describe the fundamental concept and methods for H-PLS application in forest inventory - provide an overview of the results of previous studiesÞ emphasize pros and cons for H-PLS application in forest inventory in relation to conventional field measurements and other similar laser scanning systems - highlight the main issues that should be covered by further H-PLS-based forest inventory studies.

Abstract (sommario):

An overview of the near-field-far-field (NF-FF) transformation techniques with innovative spiral scannings, useful to derive the radiation patterns of the antennas commonly employed in the modern wireless communication systems, is provided in this paper. The theoretical background and the development of a unified theory of the spiral scannings for quasi-spherical and nonspherical antennas are described, and an optimal sampling interpolation expansion to evaluate the probe response on a quite arbitrary rotational surface from a nonredundant number of its samples, collected along a proper spiral wrapping it, is presented. This unified theory can be applied to spirals wrapping the conventional scanning surfaces and makes it possible to accurately reconstruct the NF data required by the NF-FF transformation employing the corresponding classical scanning. A remarkable reduction of the measurement time is so achieved, due to the use of continuous and synchronized movements of the positioning systems and to the reduced number of needed NF measurements. Some numerical and experimental results relevant to the spherical spiral scanning case when dealing with quasi-planar and electrically long antennas are shown.

Abstract (sommario):

An increasing number of hand-held scanning systems by different manufacturers are becoming available on the market. However, their geometrical performance is little-known to many users. Therefore the Laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has carried out geometrical accuracy tests with the following systems in co-operation with the Bochum University of Applied Sciences (Laboratory for Photogrammetry) as well as the Humboldt University in Berlin (Institute for Computer Science): DOTProduct DPI-7, Artec Spider, Mantis Vision F5 SR, Kinect v1 + v2, Structure Sensor and Google’s Project Tango. In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data were acquired by measurement with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.

Abstract (sommario):

Supervisory Control and Data Acquisition (SCADA) systems and Industrial Control Systems (ICSs) have controlled the regulation and management of Critical National Infrastructure environments for decades. With the demand for remote facilities to be controlled and monitored, industries have continued to adopt Internet technology into their ICS and SCADA systems so that their enterprise can span across international borders in order to meet the demand of modern living. Although this is a necessity, it could prove to be potentially dangerous. The devices that make up ICS and SCADA systems have bespoke purposes and are often inherently vulnerable and difficult to merge with newer technologies. The focus of this article is to explore, test, and critically analyse the use of network scanning tools against bespoke SCADA equipment in order to identify the issues with conducting asset discovery or service detection on SCADA systems with the same tools used on conventional IP networks. The observations and results of the experiments conducted are helpful in evaluating their feasibility and whether they have a negative impact on how they operate. This in turn helps deduce whether network scanners open a new set of vulnerabilities unique to SCADA systems.
