Application

Design takeaway

Integrate 3D photogrammetry into the design and maintenance workflow for historic structures to enable early and precise damage detection.

How to apply

When designing restoration projects for historic buildings, plan for periodic 3D scans to track any structural shifts or crack propagation.

Project actions

  • 01When documenting existing conditions, consider using photogrammetry for a detailed 3D record.
  • 02Think about how you can track changes in a design over its lifecycle using digital models.

Method & Evidence

AimTo investigate the effectiveness of close-range photogrammetry for detecting and monitoring structural damage in historic masonry structures.
MethodComparative analysis using 3D point clouds and statistical testing.
ProcedureThe study involved acquiring 3D point clouds of cracks in a historic masonry structure at different time points. These successive point clouds were then compared using shape parameters, and a bootstrap test was applied to identify statistically significant changes indicative of damage.
ContextConservation of historic buildings and architectural heritage.

Variables

IVTime (epochs of data capture)
DVChanges in shape parameters of structural elements (indicating damage)
CVEnvironmental conditions (ideally consistent), resolution of 3D scans, photogrammetry processing parameters
04

Strengths & Limitations

Strengths

  • +Provides a comprehensive, non-contact method for damage assessment.
  • +Offers quantitative, statistically verifiable results.

Limitations

The cost of high-quality 3D scanning equipment and software can be a barrier. Processing large point cloud datasets requires significant computational power.

Reliability & validity

Reliability is enhanced by consistent scanning procedures and environmental conditions. Validity is supported by the statistical testing of detected changes against known damage indicators.

Think critically

How might the principles of 3D damage monitoring be adapted for the early detection of failures in other complex systems, such as electronic components or biological structures?

05

Design Principles

"Utilize advanced digital modelling techniques for comprehensive and continuous monitoring of structural integrity."

Traditional contact-based measurement tools for fissures and cracks provide only discrete data and are limited by accessibility. Advanced 3D modelling techniques, particularly photogrammetry, enable continuous, area-wide damage assessment, facilitating timely intervention and preservation efforts.

What This Means for Your Design

Using 3D cameras to take pictures of old buildings over time helps spot tiny cracks before they become big problems.
