Abstract The article concerns the method of architectural inventory of the historic, wooden church in Mnichów (southern Poland), built in the 18th century. During hundreds of years of operation, structural changes can be seen in it, as well as in objects located above mining operations. The article explains the principles of inventory and describes the applied method of laser scanning, starting from the design to the creation of a 3D solid model of the object, paying particular attention to the analysis based on the created point cloud. Thanks to them, the area and volumes of all rooms were determined, the verticality of columns supporting the church levels was assessed, the floor level and verticality of walls were determined, as well as the shape and level of the roof edges. Based on the research, it can be concluded that the church, as an example of a wooden religious monument, is in good condition. The detected deformations in this range do not have a destructive effect on the current state of the object, but it should be subjected to control measurements in a cyclical manner. The laser scanning method used allowed for a wide and accurate scope of the study of the geometry of the church structure, without the need to disorganize its equipment.

Proper Operation

Laser scanners are used more and more as surveying instruments for various applications. With the advance of high precisions systems, laser scanner devices can work in most real-world environments under many different conditions. In the field of mining surveying open up a new method with data capturing. Mining industry requires precise data in order to be able to have a as-built documentation of the facility. Nowadays, the mines are increasingly deepened. For the safe operation of the underground mine, special attention is paid to vertical transport and a set of devices supporting it, mounted in mining shafts. All components must meet stringent criteria for proper operation. The classic geodetic measurements and mechanical tests are long-lasting and do not always provide the full range of information needed about the condition of the object. This paper reports about terrestrial laser scanning method and system mobile terrestrial laser scanning, which has been applied at many vertical shafts in mines of Poland for determining geometric deformation of vertical shaft elements. This system gives high precision 1-3 mm in every horizontal cross – section. Processing time is very quickly and need only few staff to implement all system.

We demonstrate a fast dispersive laser scanning system by using MEMS digital micro-mirror arrays technology. The proposed technique utilizes real-time dispersive imaging system, which captures spectrally encoded images with a single photodetector at pulse repetition rate via space-to-time mapping technology. Wide area scanning capability is introduced by using individually addressable micro-mirror arrays as a beam deflector. Experimentally, we scanned ∼20 mm2 at scan rate of 5 kHz with ∼150 μm lateral and ∼160 μm vertical resolution that can be controlled by using 1024 × 768 mirror arrays. With the current state of art MEMS technology, fast scanning with <30 μs and resolution down to single mirror pitch size of 10.8 μm is also achievable.

Abstract The paper presents an application of the methodology used in the paper “Synthetic analysis of geoinformatics technologies for cultural heritage conservation, methodological approach”. The creation of the 3D model of the Rákóczi-Bánffy Castle in Urmeniș, Bistrița Năsăud County, was done by applying and integrating Terrestrial Laser Scanning (TLS) technologies and aerial photogrammetry performed with an Unmanned Aerial Vehicle (UAV). Agisoft Photoscan was used to compare the results and then they were compared with the images scanned using CloudCompare software. Thus, following the performance, with the help of the mentioned software, of a series of processing of the point cloud obtained, through the two imaging technologies, the error between the points belonging to the point cloud taken with UAV and the one taken with Laser Scanner was between 1 and 15 mm, the margin of error being acceptable for monuments without complex architectural details, so that the point cloud resulting from UAVs can be used successfully in this activity. The aim of the paper is to elaborate a geomatic methodology with an optimized cost-quality ratio, later replicable in the analysis of the current state of other constructions of the same type, knowing that over 600 castles in Transylvania alone are in a similar state, and such cases can be found in other Central European states as well.

Purpose The purpose of this paper is the presentation and research of a novel robot vision system, which uses laser dynamic triangulation, to determine three-dimensional (3D) coordinates of an observed object. The previously used physical operation principle of discontinuous scanning method is substituted by continuous method. Thereby applications become possible that were previously limited by this discretization. Design/methodology/approach The previously used prototype No. 2, which uses stepping motors to realize a discontinuous laser scan, was substituted by the new developed prototype No. 3, which contains servomotors, to achieve a continuous laser scan. The new prototype possesses only half the width and turns out to be significantly smaller and therefore lighter than the old one. Furthermore, no transmissions are used, which reduce the systematic error of laser positioning and increase the system reliability. Findings By using a continuous laser scan method instead of discontinuous laser scan method, dead zones in the laser scanner field can be eliminated. Thereby, also by changing the physical operation principle, the implementation of applications is allowed, which previously was limited by the fixed step size or by the object distance under observation. By using servomotors instead of stepping motors, also a significant reduced positioning time can be accomplished maintaining the relative positioning error less than 1 per cent. Originality/value The originality is based on the substitution of the physical operation principle of discontinuous by continuous laser scan. The previously used stepping motors discretized the laser scanner field and thereby produced dead zones, where 3D coordinates cannot be detected. These stepping motors were substituted by servomotors to revoke these disadvantages and provide a continuous laser scan, where dead zones in the field of view get eliminated and the step response of the laser scanner accelerated.

Project and digital strategies for a built heritage and its landscape in the coastal fortifications system of Northern SardiniaThe research will deal with new methods about project and digital strategies: first starting from digital survey, operated with 3D laser scanner and photogrammetry procedures, allowing, through various operations, coordinated in a workflow to obtain a single point-cloud, derived from the alignment of all scan, to generate a complex 3D model, so called Building Information Model for Heritage (BIM-H). The present research project aims to investigate and systematize, the new digital restitution strategies of the fortification existing through laser scanning and digital mapping, in particular, on military structures, as well as reflect on the problem of protection and managing this specific kind of built heritage today so far from the motivations that once determined its construction. Choosing two case studies, belonging to the coastal fortifications system of Northern Sardinia, built in the same historical period, Forte Cappellini and Punta Rossa, analyze the common constructive characters, the relationship with nature and their current state of conservation, going to verify the possibility of sharing methodologies and strategies of appropriate project. Passing from an isolated and static vision of work files to one that will be shared and dynamic, it will be possible to offer “food for thoughts” in various areas and disciplines related to Architecture, which will be able to interface simultaneously and work in progress, enriching its content and know-how. The outcome of the study will allow to recognize the emergence of a new strategy of scientific investigation and design able to positively influence the protection and conservation of military architecture of our peninsula, suggesting theoretical and operational guidelines of different nature, often in shorter times and with results almost unimaginable before, allowing for further analysis and developments the same model in future.

The three-dimensional (3D) model of erosion state of blast furnace (BF) hearth was obtained by using 3D laser scanning method. The thickness of refractory lining can be measured anywhere and the erosion curves were extracted both in the circumferential and height directions to analyze the erosion characteristics. The results show that the most eroded positions located below 20# tuyere with an elevation of 7700 mm and below 24#–25# tuyere with an elevation of 8100 mm, the residual thickness here is only 295 mm. In the circumferential directions, the serious eroded areas located between every two tapholes while the taphole areas were protected well by the bonding material. In the height directions, the severe erosion areas located between the elevation of 7600 mm to 8200 mm. According to the calculation, the minimum depth to ensure the deadman floats in the hearth is 2581 mm, corresponding to the elevation of 7619 mm. It can be considered that during the blast furnace production process, the deadman has been sinking to the bottom of BF hearth and the erosion areas gradually formed at the root of deadman.
