A Virtual Restoration Approach for Ancient Plank Road Using Mechanical Analysis with Precision 3D Data of Heritage Site

Abstract

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.

Surveying and Digital Restoration of Towering Architectural Heritage in Harsh Environments: a Case Study of the Millennium Ancient Watchtower in Tibet

“…The Digital Terrain Model (DTM) point cloud data was obtained after the removal of interference. More detailed work implementation methods can be referred to in the literature [8,29].…”

“…the removal of interference. More detailed work implementation methods can be referred to in the literature [8,29]. The eight-rotor unmanned aerial vehicle was used for surveying and mapping the Xiuba watchtower ( Figure 6); its model is DJI S1000 (DJI-Innovations Inc., Shenzhen, China).…”

“…Satellite image photogrammetry [3,4] is also used for monitoring and analysis, for which the accuracy of the results is limited. Photogrammetry [5][6][7][8][9][10][11][12][13], three-dimensional (3D) laser scanning [14][15][16][17][18][19][20], or a combination of both methods [21][22][23][24][25][26] is generally used for ancient buildings, for which the surveying and mapping results can be used for post-display, analysis, and evaluation [27][28][29][30][31].…”

A Seismic Capacity Evaluation Approach for Architectural Heritage Using Finite Element Analysis of Three-Dimensional Model: A Case Study of the Limestone Hall in the Ming Dynasty

“…In the aspect of theoretical model establishment, existing research into the mechanics of various materials and structural mechanics have been mainly used as references, and an improved theory of mechanics or models have also been adopted as research support [1][2][3][4][5], the simulation analysis tools mainly used are finite element analysis (FEA) software such as ANSYS [6][7][8][9][10], 3Muri [11][12][13], ABAQUS [14,15], SATATS [16], BrickWORK [17], TREMURI [18], etc. ; from the aspect of experimental testing, earthquake response characteristics have usually been obtained by the shaking table test [19] and ambient vibration tests [20][21][22], the intensity index is mainly detected by the triaxial compression test [23]; from the aspect of data monitoring, data obtained by monitoring tend to be used for structural safety assessments and structural strength improvement [24][25][26][27]; at the time of studying earthquake damage mechanisms, there have been macroscopic assessments for architectural heritage for some materials or structures [28][29][30][31][32], and in-depth assessments on architectural heritage monomers [33][34][35].…”

The Application of Virtual Reality Technology in Ancient Garden Restoration

“…While virtual reality provides a new way of expression for the restoration design of ancient gardens. It can use the computer to simulate the three-dimensional space of the real world and the natural environment, which allows people to feel the three-dimensional space created by computer through visual, hearing, and touch senses, and thus generate an immersive interactive scene simulation effect [4].…”
