“…Hanan et al [35] provided results for the documentation of Batak Toba houses using close-range photogrammetry. Núñez Andrés et al [36] presented a test case on digitizing façades using orthophotography. In this paper, we also support our proposed procedures with realistic test cases so that heritage experts can better relate to the content.…”

An Overview of Innovative Heritage Deliverables Based on Remote Sensing Techniques

The documentation and information representation of heritage sites is rapidly evolving. With the advancements in remote sensing technology, increasingly more heritage projects look to integrate innovative sensor data into their workflows. Along with it, more complex analyses have become available which require highly detailed inputs. However, there is a gap in the current body of knowledge of how to transfer the outputs from innovative data acquisition workflows to a set of useful deliverables that can be used for analysis. In addition, current procedures are often restricted by proprietary software or require field specific knowledge. As a result, more data are being generated in heritage projects but the tools to process them are lacking. In this work, we focus on methods that convert the raw information from the data acquisition to a set of realistic data representations of heritage objects. The goal is to present the industry with a series of practical solutions that integrate innovative technologies but still closely relate to the current heritage documentation workflows. An extensive literature study was performed discussing the different methods along with their advantages and opportunities. In the practical study, four deliverables were defined: the use of orthomosaics, web-based viewers, watertight mesh geometry and content for serious games. Each section is provided with a detailed overview of the process and realistic test cases that heritage experts can use as a basis for their own applications. The implementations are applicable to any project and provide the necessary information to update existing documentation workflows. Overall, the ideology is to increase the access to innovative technologies, better communicate the data to the different stakeholders and improve the overall usefulness of the information.

“…Data fusion is commonly applied in many cultural heritage aspects. There are many related studies that have fused the data and information in cultural heritage studies [1][2][3][4][5][6][7][8][9][10]. In principle, fusion purposely exploits intrinsic advantages and overcomes the weaknesses of sensors [11][12][13], and it is a powerful solution in cultural heritage for certain countries.…”

“…The incorporation of various types of sensor data improves spatial data accuracy, minimizes data processing complexities, and enables automated operations. Combining UAVs and MLSs provide the innovative advantage of automated operations through UAV outputs, permitting identification and the ability to focus on Earth objects from different heights and directions [5,7,21,22]. This increases flexibility so that any type of photo or lens can be used.…”

Malaysia’s heritage structures are facing challenges due to rapid local development and societal challenges that threaten their cultural and artistic values. Improving conservation approaches in this context is an urgent and crucial task. The application of geo-information technologies in laser scanning, photogrammetry, and geographic information systems (GISs) has significantly improved these conservation approaches. In this study, we fused drone images and range data from a laser scanner to construct a high-resolution three-dimensional GIS city model for one traditional Malay settlement located in Malaysia. The results showed that fusing photogrammetry and laser scanning can effectively capture the architectural uniqueness of Malay buildings, including specific façade geometries on walls, roofs, and motifs. The findings show that the development of various geoinformation approaches can assist with the conservation of Malay city heritage in this region.

“…Besides providing basic documentation, such 3D models offer new opportunities for studying, presenting and popularizing cultural heritage. Generated 3D models are also very important in conservation and restoration work, in terms of study and reconstruction of degraded and fragmented shapes and surfaces [7,8]. If physical reconstruction of an object is unachievable or unjustified from the aspect of restoration theory, virtual 3D models become the basis on which the hypotheses about the original aspect of the artistic object are developed [9].…”

Development of Expert System for the Selection of 3D Digitization Method in Tangible Cultural Heritage

et al. 2019

Selection of an appropriate 3D digitization method in the field of cultural heritage represents a big challenge, especially for non-expert users, such as conservators, art historians, archaeologists etc. Considering the above, the aim of this paper is to develop an expert system for the selection of 3D digitization method, which is the tool for suggesting for the most acceptable 3D digitization method for any individual cultural heritage object. The development of the expert system was presented through the analysis of its components, i.e. main modules-user interface, database and knowledge base. This expert system was based on different parameters defined through theoretical-methodological analysis of representative tangible cultural heritage objects. The database contains technical specifications of various 3D digitization methods, devices, and additional equipment available on market, while the knowledge base defines their limitations. The expert selection system requires as input information details about the cultural heritage object and the end user requirements. During the evaluation phase through the case studies, the system proposed satisfactory solutions depending on the entered input data.
