Opis:
Rich geometric models of the environment are needed for robots to carry out their missions. However a robot operating in a large environment would require a compact representation. In this article, we present a method that relies on the idea that a plane appears as a line segment in a 2D scan, and that by tracking those lines frame after frame, it is possible to estimate the parameters of that plane. The method is divided in three steps: fitting line segments on the points of the 2D scan, tracking those line segments in consecutive scan and estimating the parameters with a graph based SLAM (Simultaneous Localisation And Mapping) algorithm.

Opis:
Prezentowana praca związana jest z wykorzystania laserowych skanerów pomiarowych w odniesieniu do struktur kompozytowych. W pracy omówiono działanie skanerów i techniki skanowania oraz przedstawiono podstawowe zastosowania skaningu w analizie deformacji struktur kompozytowych tj. szybkie prototypowanie, naprawa uszkodzeń, modelowanie MES oraz pomiar geometrii. Analiza deformacji struktur kompozytowych przy użyciu skanowania w odniesieniu do szybkiego prototypowania umożliwia optymalizację i przeprojektowanie konstrukcji. Ponadto pozwala na wydajniejsze przeprowadzenie naprawy uszkodzeń i recyklingu. Daje także możliwość tworzenia i walidacji modeli MES poprzez porównanie deformacji uzyskanych z badań eksperymentalnych i obliczeń numerycznych. Jednakże największe możliwości skaningu laserowego w analizie deformacji związane są z pomiarem wielkości geometrycznych. W pracy dokonano wstępnej analizy deformacji kompozytowej powłoki cylindrycznej przy użyciu skaningu laserowego celem zobrazowania możliwości wykorzystania danych pomiarowych.
The presented paper is dedicated to the application of laser measuring scanners with reference to composite structures. The scanners and scanning techniques are discussed and their applications in composite structures deformation analysis i.e. rapid prototyping, damage repair, FEM modeling and the measurement of geometry are presented. The deformation analysis of composite structures using scanning with reference to the rapid prototyping provides the opportunities for optimization and reconstruction. Moreover, it allows for more efficient reparation of damage and recycling. It also offers a possibility for both the creation and validation of FE models by comparing the deformation from experiments with numerical calculations. However, the most important abilities of the laser scanners in the analysis of the deformation are connected with the measurement of geometry. In the presented work, the preliminary analysis of the deformation of the cylindrical composite panel with the help of the laser measuring scanner is presented in order to validate the possibility of using the measured data.

Opis:
An inherent feature of the piezo scanner in scanning probe microscopy is their time-varying nonlinear. This results in a distortion of images and a difficulty of the measurements that require adequate control of the current position of the cantilever with respect to the sample surface. This paper presents methods of correcting a nonlinear piezo scanner. The advantages and disadvantages of each solution are pointed out, and the developed hardware and software correction methods are described. The correction is performed by a digital system made up of high-speed analogue-to-digital converters and a FPGA programmable system in which the correction algorithms are implemented. These algorithms determine, on the basis of actual measurement data, a set of correction factors for different areas and scanning speed. This set can be modified during each scanning process. This method of hardware and software use does not slow down scanning speed, and it maintains high resolution measurements.
Inherentną cechą piezoskanerów w mikroskopach skanujących jest ich zmienna w czasie nieliniowość. Skutkuje ona zniekształceniami uzyskiwanych obrazów oraz trudnościami prowadzenia pomiarów wymagających adekwatnej kontroli aktualnego położenia cantilevera w stosunku do powierzchni próbki. W artykule przedstawiono metody korekcji nieliniowości piezoskanera. Wskazano zalety i wady poszczególnych rozwiązań oraz opisano opracowaną sprzętowo-programową metodę korekcji. Korekcja realizowana jest przez system cyfrowy złożony z szybkich przetworników analogowo-cyfrowych oraz układu programowalnego FPGA, w którym zaimplementowane są odpowiednie algorytmy. Algorytmy te wyznaczają, na podstawie rzeczywistych danych pomiarowych, zbiór współczynników korekcyjnych dla różnych szybkości i obszarów skanowania. Zbiór ten może być modyfikowany podczas każdego procesu skanowania. Metoda sprzętowo-programowa nie spowalnia szybkości skanowania, przy zachowaniu wysokiej rozdzielczość pomiarów.

W artykule scharakteryzowano zasadę działania trzech rodzajów laserowych skanerów 3D (triangulacyjnego, impulsowego, fazowego). Szczególna uwagę poświęcono skanerom fazowym. W drugiej części artykułu omówiono zastosowanie skanerów fazowych w przemyśle produkcyjnym. Pokazano, że są one doskonałym narzędziem do modelowania stanowisk pracy oraz hal produkcyjnych dla celów analiz ergonomicznych, eliminacji wąskich gardeł, balansowania linii produkcyjnych, a także wdrożenia digitalnego przedsiębiorstwa.
In the paper a principle of operation of three types (trig, impulse, phase) of 3D laser scanners is presented. The particular attention is devoted to phase scanners. The idea of taking measurements is shown in Fig. 1. There is also given the comparison of selected impulse and phase scanners. Table 1 contains the most important parameters of these scanners. In the second part of the paper there is discussed the use of phase scanners in the production industry. It is shown that they are an excellent tool for modelling workstations and factory floors in order to perform ergonomic analyses, to eliminate bottlenecks, to balance production lines as well as to implement digital factories. Fig. 2 presents an exemplary effect of scanning, modelling and analysis conducted for an enterprise of the automotive industry. The paper is summarised with the conclusion that phase scanners are suitable for modelling workstations due to their operating speed, however, they are not suggested for taking precise measurements.

Opis:
In dentistry, 3D intraoral scanners (IOSs) are gaining increasing popularity in the production of dental prostheses. However, the quality of an IOS in terms of resolution remains the determining factor of choice for the practitioner; a high resolution is a quality parameter that can reduce error in the production chain. To the best of our knowledge, the evaluation of IOS resolution is not clearly established in the literature. This study provides a simple assessment of resolution of an IOS by measuring a reference sample and highlights various factors that may influence the resolution. A ceramic tip was prepared to create a very thin object with an edge smaller than the current resolution stated by the company. The sample was scanned with microCT (micro-computed tomography) and an IOS. The resulting meshes were compared. In the mesh obtained with the IOS, the distance between two planes on the edge was approximately 100 micrometers, and that obtained with microtomography was 25 micrometers. The curvature values were 27.46 (standard deviation - SD) 14.71) μm-1 and 5.18 (SD 1.16) μm-1 for microCT and IOS, respectively. These results show a clear loss of information for objects that are smaller than 100 μm. As there is no normalized procedure to evaluate resolution of IOSs, the method that we have developed can provide a positive parameter for control of IOSs performance by practitioners.

The knowledge of the location, shape and other characteristics of spatial objects in the coastal areas has a significant impact on the functioning of ports, shipyards, and other waterinfrastructure facilities, both offshore and inland. Therefore, measurements of the underwater part of the waterside zone are taken, which means the bottom of the water and other underwater objects (e.g. breakwaters, docks, etc.), and objects above the water, such as the above-water part of the waterside, breakwaters, hydraulic constructions, and other objects of the waterside infrastructure. In this paper, project results of an integrated acoustical-optical system for inventory of hydrotechnical objects are presented. The aim of the project was to elaborate a mobile underwater scanning system which could be applied in various works that require precise, detailed and coherent, underwater and above-water measurement, especially in areas associated with surveying, inspection and monitoring of objects in coastal areas.

Opis:
A pair of rotation Risley prisms can perform superior optical pointing and tracking functions with large visual field and high accuracy. Crucial to the function implementation are the nonlinear inverse solutions to the double-prism orientation angles for tracking a given target trajectory. In the paper, a novel look-up table method is proposed to solve this problem. Because there are two groups of solutions to the rotation angles achieved from an arbitrary target point, a "jump" phenomenon occurs and generates the discontinuous curves of multi-group rotation angle solutions. According to the mapping relation between the coordinate values of the target point and the corresponding rotation angles of two prisms, we can establish the continuous solution curves by adding constraints and employing an optimization algorithm. Experimental results validate the obtained inverse solutions applicable to scan a trajectory close to the given one within an error threshold. The proposed look-up table method can provide foundation for the continuous control of the Risley-prism-based scanner in its inverse applications.Keywords: Risley prism, look-up table method, inverse solution, scanner.

In this paper, a method for calibrating the sensory system of a walking robot is proposed. The robot is equipped with two exteroceptive sensors: a 2D laser scanner and a stereo camera. When using the CAD model of the robot, the positions of both sensors defined in the robot's body reference frame can only be determined with limited precision. Our goal is to create a method which allows the robot to find the position of the mounted sensors without the need for human input. The presented results show that the method is not only fast but also more precise than calibration using the CAD model.

W artykule opisano problemy osuwiskowe na drodze relacji Kraków—Zakopane na obejściu Mogilan. Omówiono zagrożenie osuwiskami w Polsce i zniszczenia na trasach drogowych spowodowanych tym zagrożeniem. Zaproponowano wykorzystanie nowoczesnej technologii naziemnego skanera laserowego w badaniach powierzchniowych deformacji terenu osuwiskowego. Przedstawiono parametry pomiarowe naziemnego skanera laserowego 3D RIEGL VZ-400. Opisano metodykę takich badań w powiązaniu z tradycyjnymi metodami monitorowania osuwisk. W artykule przedstawiono problemy w czasie przebudowy węzła drogowego łączącego obejście Mogilan i drogę powiatową relacji Mogilany—Świątniki Górne związane z czynnym osuwiskiem. W związku z modernizacją węzła drogowego w Mogilanach pojawił się problem z nośnością podłoża i ze statecznością skarp konstruowanego nasypu drogowego. W przypadku tej inwestycji należało zabezpieczyć nasyp drogowy przed działaniem osuwiska. W celu sprawdzenia stateczności wybudowanego węzła przeprowadzono badania przemieszczeń mas ziemnych w obrębie inwestycji. W artykule przedstawiono wyniki badań ruchów osuwiskowych metodami wgłębnymi (inklinometry) oraz powierzchniowymi — metodą skaningu laserowego. Artykuł ma na celu zwrócenie uwagi na potrzebę doskonalenia metod monitorowania skarp i nasypów drogowych z zastosowaniem najnowocześniejszej technologii teledetekcji naziemnej.
This paper describes the landslide problems associated with the Cracow-Zakopane road at the Mogilany bypass. It addresses the danger of landslides in Poland and the risk of route destruction caused by landslides . The use of modern technology (terrestrial laser scanning) in the study of surface deformation in the landslide area is proposed. The article presents the measuring parameters of the 3D terrestrial laser scanner RIEGL VZ-400. It compares the methodology of such measurements with traditional landslide monitoring techniques. This paper also presents problems encountered during the reconstruction of the interchange connecting the bypass at Mogilany with the district road Mogilany-Świątniki Górne associated with active landslides. As a result of the road junction modernization in Mogilany, problems occurred with the load capacity and slope stability of the constructed road embankment. Therefore, this project had to be protected from the effects of road embankment landslides. In order to check the junction stability, the earth's movements were tested. The article presents the effects of landslide movements. The study was conducted using two techniques — the inclinometer method and the laser scanning method. The aim of this article is to draw attention to the need for improved methods of monitoring slopes and road embankments using the latest technology of remote ground sensing.

Therefore, measurements are taken of the underwater part of the waterside zone, which means the bottom of water and other underwater objects (e.g. breakwaters, docks, etc.), and objects above the water, such as the above-water part of the waterside, breakwaters, hydraulic constructions, and other objects of the waterside infrastructure. In this paper, a project of a mobile inventory system for hydrotechnical objects using data from multiple sensors operating simultaneously will be presented. The aim of the project is to elaborate a mobile underwater scanning system which could be applied in various works requiring precise, detailed and coherent, underwater and above-water measurement, especially in areas associated with surveying, inspection and monitoring of objects in coastal areas. To elaborate the concept of the system, analysis concerning existing methods of precise underwater and above-water measurement, as well as the measuring equipment available, was carried out. The results of the research were used to develop the concept of a mobile system equipped with underwater laser scanning and acoustic positioning. The technology demonstration was developed using a specially-built laboratory environment that simulates hydrotechnical infrastructure with access to GPS data. The final stage of the project will consist of testing the system in open waters.

Opis:
The methodology of the vehicle damage identification was presented in this article. Presented method used reverse engineering methodology for compare the shape of new vehicle, including CAD models of vehicle, and change of vehicle shape after damage. The method is based on three-dimensional scanning technology and photogrammetry. Identification of the defect is divided into two areas: the accurate reproduction of the vehicle surface damage and measure only changes of the base point’s position. In a first method, scanning large areas of vehicle requires connection of the consecutive scanning images of the surface to an object stuck in a random reference points. They form a grid of completing successive scanning images with very high accuracy of the surface point’s position. Measuring the angle and length between reference points, scanned surface is measured and digitized by software. However, do not always have to make as accurate measurements. In the second method there is measured only position of the vehicle base points. They may be dispersed very rare so if a damage is very small position of base points does not change. Sometimes it is reasonable to use the first and the second method together. For this purpose, the photogrammetric system is used in the first stage of the scanning surface. The vehicle specific places that are so-called base points are equipped with appropriate measuring adapters. Taking pictures of the object from these points programmatically determine the distance between reference points. This paper presents a method of surface scanning and processing on digital image scans of the vehicle for the calculation of standard deviations between the surface and the reference points. Presented adapters are used for measurement of base point’s position. Examples of calculations results of base point’s location in multi-wheeled AMV vehicle are described and illustrated in the paper.

Opis:
Soil microrelief is one of the factors affecting wind and water erosion process. Spatial variability of soil surface (microrelief) influences initiation of the surface runoff and water flow mainly through depressions, where the runoff is delayed and infiltration increases owing to the interception of the flowing water. The research was conducted to assess the changes of relief of two soils (sandy loam and fine sand) under the influence of rainfall in a model experiment. The soil microrelief was determined by means of a contactless 3D scanner using the effect of line distortion as light beam illuminating the object surface (so called Moire pattern). On the basis of obtained results, maps of the differences in the scanned surface elevations were plotted in ArcGIS programme and the soil losses volume was computed. RR indicator calculated for sandy loam was decreasing with increasing depth of simulated rainfall. No such dependence was observed for loose sand.

Opis:
The Lower Paleozoic shales of SW Sweden and Eastern Pomerania (Poland) have a common history related to the depositional and tectonic evolution of the Baltic Basin. The major tectonic events are recorded, among others, as joints, which are either exposed in outcrops in SW Sweden or recognised in deep boreholes located in Pomerania. We present a comparison of the regional joint systems recognized by multiple methods in the studied region. In effect of a statistical compilation of measurements, five joint sets (named JS 1 to JS 5) were identified, traceable between Eastern Pomerania and SW Sweden. Our analysis showed a general consistency of joint set orientations, independent of their distance to the Tornquist tectonic zone passing through the study region. Three of the joint sets, JS 1 striking NNE, JS 2 striking WNW, and JS 3 striking NNW, are found to be the most frequent sets, occurring in most sites. Having more constant orientation, the JS 1 and JS 3 served as indicators of possible rotation of the tectonic block or stress field in the region. JS 1 and JS 2 are interpreted as an effect of late Carboniferous stress relaxation after Variscan collision, while JS 3 and the E–W striking JS 4 might be related to the Early Devonian Caledonian compressive stage.

Opis:
This paper demonstrates the application of different image processing techniques to process high resolution visual images and merge it with low resolution thermograms to improve its level of detail. The same idea is applied in commercially available thermal cameras (e.g. FLIR with MSX® technology). Low resolution thermograms considered in this paper were obtained from a thermal scanner with point infrared detector (Fig. 1) sensitive to long wavelength infrared spectral range. The proposed algorithms are Laplacian, Sobel operator, embossing and Gaussian differential blur (described in section 3). The authors processed 6 different thermograms to qualitatively assess obtained results. It was done in a statistical manner through a survey and revealed that both Sobel operator and embossing provided the most clear, detailed and unambiguous results (Fig. 5). Such algorithms may be applied for processing more channels in a multispectral, cost-effective system.

Opis:
Users of machines and engineering devices force continuous improvement of their functionality and efficiency while reducing energy consumption. For this purpose, numerous sensors are installed in the machines in both drive systems and execution systems. Sensors are a source of information for control units and also allow reading parameters during diagnostic tests. The diagnostician should have the appropriate interface and knowledge of the operating principles of the tested machine. In order to facilitate the implementation of the diagnostic process even by less experienced service personnel, it is proposed to use a diagnostic interface based on the application developed in the Android system, which main element is a QR code scanner. The system uses MATLAB-Simulink, database and PHP script to work properly. This system allows performing a diagnostic test and identifying potential causes of device failure. The system has friendly interface where is implemented many useful things like graphs and visualization of device movement. The application reads the nominal operating parameters stored in the QR code of the machine and displays the next steps necessary to assess the technical condition of the object. On the basis of a comparison of registered and nominal machine parameters, the application indicates possible fault locations. The implementation of the database on an external server allows the application to run anywhere on android devices that have access to the internet. Through the registration process, it is possible to create a database of employees who have access to the system. The diagnostic system for storing all information, such as employee data or current sensor measurement values uses the MySQL database. Preliminary tests of the application carried out during diagnostics of the hydraulic and mechanical system of the building manipulator confirmed the functionality of the developed system.

Opis:
Properly prepared and carried out the measurement process of bevel gears determines its accuracy and productivity. This also has an influence on the final accuracy of bevel gears and the production costs of aeronautical gearbox. In the process of assessing the accuracy of manufacturing, majority of manufacturers of bevel gears use specialized contact coordinate measuring machines. The application of such machines as well as specialized programs dedicated to measuring the geometry of bevel gears are authoritative but in turns this requires substantial financial resources for the purchase of machinery. Thereby, this causes the limitation only of the gear assortment. Therefore, this article depicts different perspective on measurements of bevel gears using a universal measuring device, which is an optical 3D scanner ATOSII Triple Scan. Due to the use of the optical scanner ATOS II Triple Scan in measurement process, it was necessary to develop a methodology dealing with the process of assessing and accuracy, in order to achieve the desired results of measurement. This need arises from the fact that the optical scanner ATOS is not dedicated, specialized device for measuring gears. Despite of this fact, maintaining the appropriate measurement procedures and a proper preparation of the measured model allows for rapid and accurate assessment of the accuracy ofproduction. The article presents the analysis of conditions and developed rules concerning the preparation of a model for measurement. It also contains hints and a description of the measurement process. Furthermore, it depicts the rules specifying the interpretation of measurement results as well as the technical rules of their realization.
