“…-Mathematical models, instead, they are used to allow users a realistic, indoor and outdoor, experience of visiting the farmhouses through the use of remote VR viewers such as Unity or Unreal and AR on site through the use of the Augment app that allows framing the general plan or a predetermined image of the building, to virtually visualize the model even from a mobile device (Guttental, 2010, Empler, 2015). -Lastly, the use of these models is integrated through the option to navigate, via smartphones, point clouds and mesh models, using sites such as Potree WebGL and Sketchfab (Mancera-Taboada et al, 2011).…”

<p><strong>Abstract.</strong> The aim of the paper is to study the characteristics of different 3D digital models (point clouds, mesh, CSG, BIM) for the realization of a museum of historical buildings widespread in the territory of South Tyrol through the 3D modeling of several farmhouses between the towns of Collalbo, Longomoso and Siffiano, in the Renon area. Therefore, moving from a defined case study, the paper proposes a workflow for model choice, use, and sharing considering also users profile.The objective is to create a system that allows, the sharing, both on site and remotely, of farmhouses digital models, information, images and documents found during the research. The purpose is to enhance the territory with the promotion of its knowledge taking into account also the importance of the participative aspects. In fact, in this system, are crucial and are a fundamental part of the safeguarding process, effectively increasing the information content and filling any information gaps, allowing the system to grow and become increasingly considerable and effective for the knowledge, documentation and enhancement of the territory.</p>

A Mobile Augmented Reality System for the Real-Time Visualization of Pipes in Point Cloud Data with a Depth Sensor

Augmented reality (AR) is a useful visualization technology that displays information by adding virtual images to the real world. In AR systems that require three-dimensional information, point cloud data is easy to use after real-time acquisition, however, it is difficult to measure and visualize real-time objects due to the large amount of data and a matching process. In this paper we explored a method of estimating pipes from point cloud data and visualizing them in real-time through augmented reality devices. In general, pipe estimation in a point cloud uses a Hough transform and is performed through a preprocessing process, such as noise filtering, normal estimation, or segmentation. However, there is a disadvantage in that the execution time is slow due to a large amount of computation. Therefore, for the real-time visualization in augmented reality devices, the fast cylinder matching method using random sample consensus (RANSAC) is required. In this paper, we proposed parallel processing, multiple frames, adjustable scale, and error correction for real-time visualization. The real-time visualization method through the augmented reality device obtained a depth image from the sensor and configured a uniform point cloud using a voxel grid algorithm. The constructed data was analyzed according to the fast cylinder matching method using RANSAC. The real-time visualization method through augmented reality devices is expected to be used to identify problems, such as the sagging of pipes, through real-time measurements at plant sites due to the spread of various AR devices.

ABSTRACT:Terrestrial Laser Scanning (TLS), 3-D modeling and its Web visualization are the three key steps needed to perform storage and grant-free and wide access to cultural heritage, as highlighted in many recent examples. The goal of this study is to set up 3-D Web resources for "virtually" visiting the exterior of the Abbaye de l'Epau, an old French abbey which has both a rich history and delicate architecture. The virtuality is considered in two ways: the flowing navigation in a virtual reality environment around the abbey and a game activity using augmented reality. First of all, the data acquisition consists in GPS and tacheometry survey, terrestrial laser scanning and photography acquisition. After data pre-processing, the meshed and textured 3-D model is generated using 3-D Reshaper commercial software. The virtual reality visit and augmented reality animation are then created using Unity software. This work shows the interest of such tools in bringing out the regional cultural heritage and making it attractive to the public.
