3D reconstruction for prosthetic design

Abstract

This paper investigates the use of an inexpensive passive method involving 3D surface reconstruction from digital images taken at multiple views. The modification of existing model-based reconstruction, mainly on the deformation process of vertices is discussed and the results of different objects show a good possibility for using a passive method in orthotic and prosthetic devices. For a dummy limb, the fitting of the model with the data shows a satisfactory result. The results of 15 measurements of different length between both reconstructed and actual dummy limb show both the model and the actual limb data are highly correlated. The methodology developed is shown to be useful for prosthetic designers as an alternative to manual impression during the design.
