Automatic Lens Placement for Personalized 3D Printed Eyewear

We use Kiri Engine to reconstruct a 3D face from smartphone photographs and MediaPipe to detect facial landmarks in rendered views of the model. Scripts in Blender project these landmarks onto the face mesh and use the resulting eye and nose references to position the lenses and nose pads. With the lenses held fixed, we manually refine the frame in Blender using mesh editing and lattice deformation, then fabricate a personalized eyewear prototype by 3D printing.

About this research

Lens placement.
Frame fitting.

Lens placement provides a fixed reference for personalizing the surrounding frame.

Personalized eyewear must coordinate lens positions, nose-pad contact, and frame shape for each face. Our workflow first establishes lens positions from image-derived eye references, then keeps the lenses fixed while the designer adjusts the surrounding frame in Blender.
