“…Currently, TLS play a very important role in a wide range of purposes that can be directly extrapolated to cultural heritage [37], including the follow-up of an intervention [38], defect detection [39], or the reproduction of existing models [40,41]. However, the high cost of these technologies, the need for specialized management and the pre-processing of the information acquired can be considered as challenges and/or disadvantages.…”

Many projects concerning the protection, conservation, restoration, and dissemination of cultural heritage are being carried out around the world due to its growing interest as a driving force of socio-economic development. The existence of reliable, digital three-dimensional (3D) models that allow for the planning and management of these projects in a remote and decentralized way is currently a growing necessity. There are many software tools to perform the modeling and complete three-dimensional documentation of the intervened monuments. However, the Architecture, Engineering and Construction (AEC) sector has adopted the Building Information Modeling (BIM) standard over the last few decades due to the progress that has been made in its qualities and capabilities. The complex modeling of cultural heritage through commercial BIM software leads to the consideration of the concept of Heritage BIM (H-BIM), which pursues the modeling of architectural elements, according to artistic, historical, and constructive typologies. In addition, H-BIM is considered to be an emerging technology that enables us to understand, document, advertize, and virtually reconstruct the built heritage. This article is a review of the existing literature on H-BIM and its effective implementation in the cultural heritage sector, exploring the effectiveness and the usefulness of the different methodologies that were developed to model families of elements of interest.

“…Whenever the number of photo shots is increased, computational times in SfM reconstructions are exponentially growing (Golparvar-Fard et al, 2011). Despite taking many photo scenes from the same view angles with the same zoom settings, shooting photos from different perspectives, different viewpoints, and different zoom settings are highly recommended.…”

Numerical simulation of flood propagation requires proper understanding of all processes involved. Also, special care has to be taken to adequately represent the urban topography, taking into account typical urban features like underpasses and hidden alleyways. Incorrect input data will affect the numerical model results, which may lead to inadequate flood-protection measures or even catastrophic flooding situations. This thesis explores how to include particular urban topographic features in urban flood modelling.Aerial Light Detection and Ranging (LiDAR) systems offer opportunities for achieving good quality topographic data, with less fieldwork on the ground. Even though aerial LiDAR data have long been used in many applications, conventional top-view LiDAR data can not quite capture some hidden urban features. However, recent improvements in Structure from Motion (SfM) techniques provide opportunities to achieve improved quality topographic data by using multiple viewpoints, including side-view data.This dissertation explores insights into the capabilities of assimilating SfM point cloud data by using multi-source views as input for enhancing 2D urban flood modelling. Side-view SfM point cloud data are collected and merged with conventional top-view LiDAR point cloud data to create novel Multi-Source Views (MSV) topographic data. The main objectives of this research are (i) to provide insight into the capabilities of using computer-based environments; (ii) to explore the benefits of using the new MSV data; (iii) to enhance 2D model schematizations; (iv) to compare simulated results using new MSV data and conventional top-view LiDAR data as input for urban flood models; and (v) to help developing flood-protection measures. Findings showed that simulation results using conventional top-view LiDAR-DSM as input show the least flood inundation areas and results contained many dry areas. This is because conventional LiDAR-DSM does not capture hidden urban features like underpasses, high trees, overarching structures, which behave as obstacles in 2D model schematics. When applying extended top-view LiDAR-DBM+ and the newly developed MSV-DEM as input, simulation results showed m...

“…For instance, (Golparvar-Fard et al 2011) have also compared two 3D scanning methods, camera based and 3D laser scanning, in modelling the as-built status of a construction site. They concluded that camera based methods are less accurate, but that both methods are capable of producing 3D representations for visualizing the environment, from different viewpoints.…”

Global trends of ecology and sustainable development, safety awareness, changing legislation, and urbanization, together with the economic situation, force industry to find solutions for extending product lifecycles, while maintaining and improving machine system performance and other properties during the lifecycles. Together with these societal issues, firms are struggling with competitiveness. This chapter introduces the new Use-it-Wisely (UIW) approach to upgrading rock crushers at customer sites. The higher level problem needing to be solved concerned making upgrade delivery projects profitable and more desirable for customers, manufacturing OEMs and suppliers. The main recognized and treated bottlenecks were related to knowing the actual status of the upgrade target, communication and collaboration with stakeholders, verification and validation of upgrade specifications and an efficient information flow between the stakeholders. Augmented reality (AR), Virtual environments (VE), camera based 3D scanning, and cloud based solutions are the selected pieces of technology for solving the bottlenecks. They enable better communication, collaboration and involvement of all stakeholders, including customers, internal stakeholders, suppliers and partners. They also better enable the planning and discussing of service quality activities. Product life-cycle management (PLM) is the framework for developing and managing product related information, processes and collaboration expanding towards product middle-of-life, end-of-life, and service lifecycle management. This study is a proof-of-concept that demonstrates the potential of contributions to business model innovations and game changes for upgrading business.
