Surface Reconstruction Using Reference Model For Future Prosthetic Design

Existing methods that use a fringe projection technique for prosthetic designs produce good results for the trunk and lower limbs; however, the devices used are expensive. this study proposes the use of an inexpensive passive method involving 3d surface reconstruction from digital images taken at multiple views. the design and evaluation methodology comprise of a number of techniques suitable for prosthetic design. a method that fits a 3d reference model of an object (e.g., a limb) to the target (actual) 3d data to reconstruct the surface of the target is presented. the reference model is generated using a computer algorithm while the target is reconstructed using a shape-from-silhouette (sfs) technique in an approximate circular motion. the fitting process involves deforming the object vertices of the reference model to better match the actual object. the experimental results demonstrate the potential of using the proposed method in prosthetic devices.
