BACKGROUND

VS.

NON- CALIBRATED IMAGES OF FOOTPRINT

CALIBRATED IMAGES OF FOOTPRINT

Faster and simple

Accurate measuring and modelling of the object

Less Expensive

Higer quality- Precise measurement and geomentrical accuracy

Advanced image processing techniques

Feasible option for applications such as cultural heritage preservation, virtual reality, and entertainment

Useful for Engineering, Architecture and Research

Literature Review

LITERATURE REVIEW

The literature review of 3D reconstruction indicates a growing interest in the use of Context Capture software for creating accurate and detailed 3D models in various industries, including construction.

Prior work

Engineering/ Architecture-

  • Surface analysis: Surface of an infrastructure can be inspected for any deformations such as cracks and chipping.

Restoration and Planning

  • Defects detected can be planned to retrofit using 3D model for a Histroic Structure or a landmark for preseravation purposes and can also be used for creating replicas

Visualization and Presentation

  • 3D model allows engineers to collaborate and work offsite and get accurate results
  • Generated models can be used for research purposes

Design Analysis

  • 3D model can be used for structural analysis- strength determination
  • Safety analysis using simualtions of potential hazards such as earthquake.

Restoration Planning

A study by Wang and colleagues (2019) used Context Capture to generate 3D models of a construction site for progress monitoring and quality control. The authors reported that the software was able to accurately capture the site's geometry and produce high-quality models suitable for visualization and analysis.

In a study by Jiang and colleagues (2018), Context Capture was used to reconstruct a historic building facade in Shanghai. The authors found that the software was able to create a highly detailed 3D model of the facade, which could be used for conservation and restoration planning.

A study by Yang and colleagues (2018) used Context Capture to generate a 3D model of a tunnel excavated using the New Austrian Tunneling Method. The authors found that the software was able to accurately capture the tunnel geometry and produce a detailed 3D model suitable for analysis and visualization.

In a study by Zhao and colleagues (2018), Context Capture was used to create a 3D model of a bridge for structural analysis and monitoring. The authors reported that the software was able to produce an accurate and detailed model of the bridge, which could be used to identify structural issues and monitor changes over time.

Knowledge gaps

Knowledge Gaps

1.

Development of new Advanced cameras and sensors

  • Sony A7R IV
  • Canon EOS R5

2.

Improved software for 3D modelling

  • Reality Capture
