The survey of ancient buildings is complex work. Chinese wooden buildings, with their complex structure and exquisite decorations, pose a great challenge for survey work. Therefore, it is necessary to introduce unmanned-helicopter photogrammetry and laser scanning technology to facilitate the work. This paper uses three cases to explain the application of these new technologies in China’s architectural heritage protection and analyzes the special features and main operational techniques of the survey work.

<p>The paper presents the first results of an interdisciplinary research conducted by the Department of Architecture of Roma Tre University aimed at developing guidelines for enhancement of minor architectural heritage, urban  and suburban. The research evaluates the creation of a widespread museum that exploit cultural dissemination technologies in augmented reality. The economic crisis, not yet overcome, leads to rethink urban development and heritage conservation, reorienting design towards techniques and practices of reuse. These strategies represent one of the most effective ways to enhance and protect the minor architectural heritage, often protagonist of degradation and abandonment. It seems necessary that the architectural heritage protection has been articulated through contemporaneity, adapting itself to the age of Information Communication Technology. In addition to the architectural heritage, strictly intended as a monument, Italy has a complex system of goods well explained, in the broadest sense, as "minor architectural heritage ". This approach makes possible to identify the Italian Historical Cities as a new category of widespread heritage to be protected. Consequently, it emerges the need to put aside the discretization in punctual assets, approaching an entire system of architectural goods, characterized by a high degree of complexity. Valuing the latter in a sustainable way also passes through new technologies as augmented reality.</p>

E Mail

In the office, computers are central to a range of tasks. The architects’ days are mostly spent at screens: checking and responding to e-mail, finding “precedent” images that provide the inspiration for design, researching building materials and new technologies, and most centrally of all using one of a range of computer-aided design packages. Watching them at work, I observe screens flicking perpetually between these programs and tasks. Observing their movements, I find it clear that these architects are thoroughly digital humans, their capacities of thought and action indissoluble from digital technologies that saturate this working environment....

Architectural Treatises

Building Information Modeling (BIM) has attracted wide interest in the field of documentation and conservation of Architectural Heritage (AH). Existing approaches focus on converting laser scanned point clouds to BIM objects, but laser scanning is usually limited to planar elements which are not the typical state of AH where free-form and double-curvature surfaces are common. We propose a method that combines low-cost automatic photogrammetric data acquisition techniques with parametric BIM objects founded on Architectural Treatises and a syntax allowing the transition from the archetype to the type. Point clouds with metric accuracy comparable to that from laser scanning allows accurate as-built model semantically integrated with the ideal model from parametric library. The deviation between as-built model and ideal model is evaluated to determine if feature extraction from point clouds is essential to improve the accuracy of as-built BIM.

The Impact

Documentation, data processing, and representation of Architectural Heritage through digital models are one of the main challenges in the field of conservation, preservation, management, and inclusive use and understanding of European heritage assets. In this framework, the impact of Industry 4.0 is more and more crucial, since new technologies, devices, and digital environment are strongly influencing the ways in which heritage contents are explored, used, managed, and shared, also in citizens' everyday life. In this direction, the INCEPTION project – founded by the European Commission within the Horizon 2020 programme – develops key-targeted innovations in efficient 3D digitization methods, post-processing modelling tools, semantic web-based solutions, and applications to ensure a wide and aware access to digital Cultural Heritage. This chapter presents main actions achieved by INCEPTION.

Heritage Protection

At present, in terms of the architectural heritage protection, the rapid development of Chinese economics and the accelerating urbanization process have caused a great deal of "constructive destructions" to the architectural heritage and have accelerated its demise. In order to change the situation and to deepen the people's understanding to the value of the architectural heritage, the paper will make further analysis and research on the culture value and economics value from the view of cultural economics and then give the architectural heritage the third-largest value -- social value. The ultimate goal is to establish the architectural heritage value system so as to promote the protection and the sustainable development of the architectural heritage.

The Church

The article discusses three objects of Kaunas architectural heritage, which represent different cases of heritage treatment in the years of independence. In Soviet times, a building of the Communist Party Committee blocked the gothic church of St Gertrude to an enclosed yard. This building was demolished by the civic initiative organised by the Sąjūdis movement in 1989. The church was restored using the state funds in 1991–1994. A small wooden suburban manor was built in Baritonai Street in the middle of the 19th century. It had belonged to the Petravičiai family for one hundred years. The house has been deserted since 1994. The local authority of Kaunas has been working on privatisation documents for so long that the house has entirely crumbled. A detached house of the famous architect Vytautas Landsbergis-Žemkalnis represents the interwar modernism. After restoration of independence, it was returned to his family. The family sold the house. Although it was included to the Register of Cultural Property and declared protected by the state, the new owners have transformed the exterior of the house completely in 2004–2005. The two last-mentioned examples symptomatically reveal a crisis of values in Lithuanian heritage protection. A punctilious legalism enables institutions responsible for heritage protection to hide under the veil of law-making rather than bother with alternative possibilities of preservation. Santrauka Straipsnyje aptariami trys Kauno architektūros paveldo objektai, reprezentuojantys skirtingus elgesio su paveldu atvejus nepriklausomybės metais. Gotikinę Šv. Gertrūdos bažnyčią į uždarą kiemą užblokavęs komunistų partijos komiteto pastatas buvo nugriautas Atgimimo sąjūdžio organizuotos visuomenės iniciatyva 1989 m., o pati bažnyčia 1991–1994 m. restauruota valstybės lėšomis. Medinis XIX a. vidurio priemiesčio dvarelis Baritonų g. 6, šimtą metų priklausęs Petravičių šeimai, nuo 1994 m. stovi tuščias, miesto savivaldybė tol rengė dokumentus privatizacijai, kol namas visai sugriuvo. Žymaus architekto Vytauto Landsbergio-Žemkalnio kotedžas, reprezentuojantis tarpukario modernizmą, atkūrus nepriklausomybę buvo grąžintas šeimai. Jos nariai namą pardavė, naujieji savininkai 2004–2005 m. visiškai pertvarkė išorę, nors objektas jau buvo įtrauktas į Kultūros vertybių registrą ir paskelbtas valstybės saugomu. Šie du pavyzdžiai simptomiškai atskleidžia vertybių krizę Lietuvos paveldo apsaugos srityje. Utilitarus legalizmas leidžia paveldosaugos institucijoms prisidengti įstatymo formule ir nesivarginti ieškant alternatyvių išsaugojimo galimybių.

Field survey provides data for further research and is a key link in research on traditional settlements and other architectural heritage. However, due to the complexity of the landform, layout, orientation of buildings, forms and structures of traditional settlements, mapping and other fieldwork may take much time and efforts and are very difficult. Besides, satellite remote sensing data are few. Therefore it is necessary to introduce some advanced equipment and technology for spatial information acquisition. Through years of experiments with aerial and ground-based equipments, the author finds that small unmanned helicopter, with its multi-functional spatial information acquisition capacity, is the best choice for the research of traditional settlements and other related fields.

In order to fabricate the micro cavity with complex structure on stainless steel, the technology of micro electrochemical machining based on surface modification by fiber laser is adopted. Heating scan on the surface of 304 stainless steel by using fiber laser can realize marking. In the process of laser heating and metal melting on the surface of 304 stainless steel, oxide layer can be formed and phase transformation can also occur, and the corrosion resistance layer with predefined pattern is formed. In the next process of micro electrochemical machining, the laser masking layer severs as the protective layer to realize micro machining of micro cavity. A newly developed device of electrochemical micro machining based on surface modification by fiber laser can meet the micro machining requirement. After laser masking processing through laser scanning on the surface of the 304 stainless steel, the passivation electrolyte and high-frequence-pulse electrochemical machining power supply were adopted, and the samples with typical structures by using electrochemical micromachining with fiber laser masking were fabricated.
