Abstract

Building heritage contributes to the historical context and industrial history of a city. Brick warehouses, which comprise a systematic interface between components, demand an interactive manipulation of inspected parts to interpret their construction complexity. The documentation of brick details in augmented reality (AR) can be challenging when the relative location needs to be defined in 3D. This study aimed to compare brick details in AR, and to reconstruct the interacted result in the correct relative location. We applied photogrammetry modeling and smartphone AR for the first and secondary 3D reconstruction of brick warehouse details and compared the results. In total, 146 3D AR database models were created. The AR-based virtual reconstruction process applied multiple imagery resources from video conferencing and broadcast of models on the Augment® platform through a smartphone. Tests verified the virtual reconstruction in AR, and concluded the deviation between the final secondary reconstructed 3D model and the first reconstructed model had a standard deviation of less than 1 cm. AR enabled the study and documentation of cross-referenced results in comparison with the simplified reconstruction process, with structural detail and visual detail suitable for 3D color prints.

Highlights

Introduction of Brick DetailsRemote Sens. 2022, 14, One of the best approaches to explore the historical context of a city is from its industry-related constructions
The reconstructions of micro-systems were performed from a remote site through the control of screenshots or videos and softwareassisted rendering in separate locations, including the laboratory, office, and home
Value can be added to the augmented reality (AR) process by means of interaction, composition, communication, confirmation, and recursion in the development of the warehouse and its preservation attempts

Construction materials such as bricks contribute to the spatio-temporal background and geographic distribution of details by means of layout, style, and system, under the impact of industry, culture, and technology. Industry and brick warehouses represent two of the main entry points to understand the early history of Taiwan. Most industrial buildings were designed using bricks. Brick warehouses (Figure 1) were designed to process raw materials (e.g., sugar, alcohol, camphor, and tobacco), support heavy industry (e.g., ordnance and railroad), store goods (e.g., rice), and exchange resources at trade ports. The elucidation of the relationship between the two subjects can deepen our knowledge of tangible heritage according to different stages of development
