Schematic

A ROS-based capture system time-synchronises an Intel RealSense D435i depth camera with a lab-built FLIR thermal camera. Point-cloud registration and global optimisation reconstruct a full 3D body model, and thermal imagery is UV-mapped onto the mesh to output a textured 3D thermal body for analysing surface heat distribution.

I designed the hardware, software and mechanical structure.

Highlights

  • ROS-based multi-camera time synchronisation
  • Point-cloud registration and global optimisation
  • UV-mapped thermal texture on a 3D mesh
  • Face measurements: mean error 0.184 mm in size, 0.175 °C in temperature
