Foot shape reconstruction, biomechanical foot modeling,plantar pressure cartographies.
Foot problems due to diabetics, age or joint disease are
treated by application of personalized foot insoles.
Designing an insole requires the knowledge of the plantar
foot shape. Several techniques are used to get or estimate
the 3D foot shape.
Among them, plantar pressure cartographies are used by
podiatrists to estimate the design of the foot insoles.
Unfortunately, due to the lack of conversion tool between
pressure maps and foot shape, several iterations of design
and measurements are needed.
In the present study, a new method aiming to extract the
3D foot shape under pressure is presented. The main
elements of the foot that induce the plantar pressure
distribution are presented in a specific biomechanical
model. We present and discuss extraction of the 3D
pressured foot shape from the barefoot plantar pressure
