PROJECT TOPICConstruction, Infrastructure & Maintenance
Structural Crack Monitoring Drone
A civil engineering aerial survey concept studying sub-millimeter optical crack detection, laser distance standoff control, and high-density 3D photogrammetry models for dams, retaining walls, and highway flyovers.
Quantifiable Infrastructure Structural Audits
- ✓Maintains fixed millimeter standoff from vertical concrete faces using optical rangefinders.
- ✓Captures sub-millimeter crack opening widths and tracks growth over recurring seasonal inspections.
- ✓Constructs digital twin photogrammetry meshes for structural engineering evaluation.
The Engineering Challenge
Problem / Objective
High-level visual inspections on dam spillways and elevated highway pillars are dangerous for human inspectors and prone to subjective notes.
