iOS pipeline that captures foot geometry with ARKit LiDAR, reconstructs a dense mesh with Open3D (alpha-shape + smoothing), and exports print-ready insole models (OBJ/STL) in about 2 minutes.
Project Overview
Built at TreeHacks 2025, we convert iPhone depth and point-cloud data into custom orthotic geometry. The processing stack uses Open3D for denoising/meshing, Trimesh for surface inversion and insole shaping, and OpenCV distance-transform refinement for contour fit before final export.
Some Features
- ARKit LiDAR Capture: Uses iPhone LiDAR to acquire high-resolution foot surface data.
- Mesh Reconstruction: Generates printable geometry with Open3D alpha-shape meshing and smoothing.
- Insole Synthesis: Applies Trimesh-based inversion/shaping and OpenCV contour refinement.
- Print Pipeline: Produces OBJ/STL files compatible with low-cost FDM printers in about 2 minutes.
