“…The dimensional data of the building, of the machinery stored inside and of the site were respectively acquired by means of the following tools: TLS Leica ® C10, handheld scanner (HS) Trimble ® DPI-8 and geodetic global navigation satellite system (GNSS) Leica ® GS12. The use of a HS in the indoor survey is motivated by the presence of machinery causing the problem of cast-shadows (Hu et al, 2016) thus determining several blind spots not detectable by the TLS. Raw data collected as 3D point clouds from several surveys have been homogenised into a single platform.…”

Food industry is the production sector with the highest energy consumption. In Europe, the energy used to produce food accounts for 26% of total energy consumption. Over 28% is used in industrial processes. Recently, European food companies have increased their efforts to make their production processes more sustainable, also by giving preference to the use of renewable energy sources. In Italy, the total energy consumption in agriculture and food sectors decreased between 2013 and 2014, passing from 16.79 to 13.3 Mtep. Since energy consumption in food industry is nearly twice the one in agriculture (8.57 and 4.73 Mtep, respectively), it is very important to improve energy efficiency and use green technologies in all the phases of food processing and conservation. In Italy, a recent law (Legislative Decree 102, 04/07/2014) has made energy-use diagnosis compulsory for all industrial concerns, particularly for those showing high consumption levels. In the case of food industry buildings, energy is mainly used for indoor microclimate control, which is needed to ensure workers' wellbeing and the most favourable conditions for food processing and conservation. To this end, it is important to have tools and methods allowing for easy, rapid and precise energy performance assessment of agri-food buildings. The accuracy of the results obtainable from the currently available computational models depends on the grade of detail and information used in constructional and geometric modelling. Moreover, this phase is probably the most critical and time-consuming in the energy diagnosis. In this context, fine surveying and advanced 3D geometric modelling procedures can facilitate building modelling and allow technicians and professionals in the agri-food sector to use highly efficient and accurate energy analysis and evaluation models. This paper proposes a dedicated model for energy performance assessment in agri-food buildings. It also shows that by using advanced surveying techniques, such as a terrestrial laser scanner and an infrared camera, it is possible to create a three-dimensional parametric model, while, thanks to the heat flow meter measurement method, it is also possible to obtain a thermophysical model. This model allows assessing the energy performance of agri-food buildings in order to improve the indoor microclimate control and the conditions of food processing and conservation.

Abstract. Most traditional methods of ancient garden restoration are to record with text, charts and graphic drawings and then observe the restoration effect through miniatures or color effect pictures. However, those methods are too inflexible, which cannot reflect the unique artistic conception and steric space of ancient gardens. As an important technology in the computer information age, virtual reality technology is featured with immersion, interaction and imagination. While gardens pay much attention to the experience and feeling of people, which places a high application value on the virtual reality technology in the restoration and scene reconstruction of ancient gardens. Through the analysis of methods and means of virtual reality technology in the restoration of ancient gardens and based on the restoration design of Ancient Lotus Pond Garden, this paper has studied the detailed application methods of virtual reality technology in the restoration of ancient gardens and completed the restoration design of Ancient Lotus Pond Garden. The study shows that human-computer interaction technique allows modern people to experience virtual wandering and scene reappearance in ancient gardens and feel the unique spatial artistic conception of ancient gardens.

“…For the majority of the 3D modeling based on precisely measured data, even though it is used in some areas like archaeology [13][14][15], historic building [16,17], and paleobiology [18], their fundamental objectives are still limited to information preservation and image display, and fail to support the in-depth research of cultural relic restoration. We have to pay more attention to a few examples.…”

Abstract:The ancient plank road is a creative building in the history of Chinese ancient traffic through cliffs. In this paper, a virtual restoration approach for ancient plank road using mechanical analysis with precision 3D data of current heritage site is proposed. Firstly, an aero photogrammetry with multiple view images from Unmanned Aerial Vehicle (UAV) imaging system is presented to obtain the 3D point cloud of ancient plank roads, which adopts a density image matching and aerial triangulation processing. In addition, a terrestrial laser scanner is integrated to obtain detail 3D data of the plank road. Secondly, a mechanical analysis method based on the precision 3D data of the current plank roads is proposed to determine their forms and restore each of their components with detail sizes. Finally, all components and background scene were added to the existing model to obtain a virtual restoration model, which indicates that it is effective and feasible to achieve a three-dimensional digital and virtual restoration of ancient sites. The Chiya Plank Road is taken as a virtual restoration example with the proposed approach. The restored 3D model of the ancient plank can be widely used for digital management, research, and visualization of ancient plank roads.
