A method comprising:
- receiving, by a processing device, a two-dimensional pressure map of an individual's foot;
- receiving, by the processing device, a plurality of images of the individual's foot;
- and computing a three-dimensional reconstruction of the individual's foot in a form of a smooth three-dimensional surface comprising an upper portion and a lower portion, wherein the upper portion is computed based on the plurality of images by utilizing a partial differential equation (PDE) to evolve a surface representative of the individual's foot using depth data from the plurality of images by minimizing a fitting score;
- and wherein the lower portion is computed based on the two-dimensional pressure map to account for an underside of the individual's foot that is not visible in the plurality of images by applying a penalty to the fitting score based on a mismatch between a boundary of the two-dimensional pressure map and a boundary of the surface.
