This paper provides a scheme to construct three dimensional (3D) model fast using laser scanning data. In the approach, firstly, laser point cloud are scanned from different scan positions and the point cloud coming from neighbor scan stations are spliced automatically to combine a uniform point cloud model, and then feature lines are extracted through the point cloud, and the framework of the building are extracted to generate 3D models. At last, a conclusion can be drawn that 3D visualization model can be generated quickly using 3D laser scanning technology. The experiment result shows that it will bring the application model and technical advantage which traditional mapping way can not have.

Fabric Surface

Fabric surface analysis, as part of fabric analysis, is very important for the textile manufacturing process and is traditionally based on human-labor or image processing which is a conventional automatic method. However, image quality is influenced by ambient light, background light and optical properties of the surface. In this paper, we present a three dimensional modeling techniques for the reconstruction of carbon-fiber fabric surface. Firstly, a dense and scattered points cloud is collected using 3D laser scanning system after necessary data quality analysis. Secondly, the original points cloud is preprocessed according to classification. Finally, three-dimensional fabric surface model is reconstructed using screened Poisson reconstruction algorithm. The experimental results show that the reconstructed model is acceptable.

Recently, a line of research devoted to the creation of three-dimensional metric simulated models of digital twins has been actively developing. The goal of creating digital twins is to transfer the complicated manufacturing processes, that are performed while monitoring the state of real objects, to a computer environment where a three-dimensional information model was first created. The key requirements are accuracy and efficiency within the conditions of design, construction and operation of real objects when making changes to them. These requirements are met by an active method of the Earth remote sensing, such as laser scanning. Terrestrial laser scanning is used to model objects over a relatively small area and to achieve maximum accuracy. The task of creating digital twin models poses higher requirements for choosing a field stage laser scanning technique and has many features when performing three-dimensional modeling using field data. The article proposes technique of three-dimensional modeling for creating building information models. It analyses the accuracy of the terrestrial laser scanning results. A warehouse space to be reconstructed was selected as the subject of the study. Using the example of laser scanning data for this object, it was indicated that the method under consideration allows ensuring the accuracy of creating a three-dimensional information model up to 1 cm. The laser scanning data of the object show that the considered method ensures 3D information model accuracy up to 1 cm.

Abstract. The Venetian galea (galley), dominating the Mediterranean Sea for almost 1000 years, is one of the most emblematic and fascinating objects in the history and culture of the Serenissima Republic of San Marco, the official name of ancient Venice. This boat has changed according to the needs and developments that have taken place over the centuries, proving versatile and powerful in military and commercial use.Unfortunately, no complete specimen has been received, and everything that can be known about galleys derives from paintings made in different eras, in models and in some original parts, kept inside the Naval Historical Museum of Venice.Another source are some manuscripts, where part of the traditional shipbuilding knowledge is handed down. To understand a galley it is necessary to understand which techniques were used by the proti (directors of the ancient shipyard) which differ substantially from the current design.These techniques were the synthesis of knowledge handed down from person to person and which did not make use of design drawings such as are used today. To obtain the reconstruction of a galley, lacking complete original drawings, we collected and analyzed different documentation that testified the ancient forms.The presented work aims to reconstruct a digital model of a galea starting from the photogrammetric and laser scanning survey of a wooden model of the hull of half of a 25-bench galley of the mid-seventeenth century. The surveyed maquette and brought back to the real scale was integrated by some artifacts present at the Naval History Museum of Venice, surveyed with photogrammetric techniques and laser scanning too.In this way a hypothetical configuration was reconstructed (by synthesis of collected and historical data) which shows the shape that this boat could reasonably have had. The result is a digital model, then printed to the scale, obtained by three-dimensional modeling starting from the point clouds of the maquette and the original artifacts. This final model has been compared with all the iconographic and documentary sources for its historical validation.The results obtained were used for a set-up aimed at enhancing the museum, because it was intended for a large audience.

3D (three-dimensional) laser scanning can be used to collect spatial location of points rapidly and abundantly, and obtain three-dimensional coordinates of the target surface, which provides new technical means for the rapid creation of three-dimensional image model of the object. A three-dimensional modeling study on spatial object was carried out using the spatial data captured via ground-based 3D laser scanner in the Hui-Quan substation. The experiment result shows that rapid 3D visualization modeling on buildings can be achieved via the methods and procedures mentioned above. It has solved that the traditional equipment and the measuring technique is insufficiency in the special domain. It will bring the application mode and technical advantage, which tradition mapping way can not have. A platform for three-dimensional model of the substation can be achieved for the resources, landscape, security, environmental management and other social resources of digital, networked and dynamic visualization.By taking WuXi Hui-Quan Substation as the research object, building 3D models by Three-dimensional laser scanning technology and embedding 3D-GIS, Meanwhile, combining existing 2D-geographical spatial data, data preparation, construction of 3D-model, 3D-visualization, space inquiry and analysis, information management are given systematic analysis and research. In the end, in the programming environment of C#2.0, Skyline software is employed with its open Application Programmed Interface (API), which constructs 3D-scenes and 3D-terrain models of WuXi Hui-Quan Substation and comes to the realization of 3D-visualization, property inquiry and edit of Attribute data.
