A patient visits a clinic for surgery or a prosthesis to correct an abnormal gait. During the visit the patient's leg is measured or digitized and the patient's gait is digitized. The patient returns to a remote location for recovery from surgery or use of prosthesis. At a later time, a video of the patient walking is taken and sent to the clinic for analysis. The 3D motion of the gait is reconstructed using the video and knowledge of the patient's leg and is inspected for significant differences from than recorded in the clinic. Currently, we are able to reconstruct the three-dimensional gait from two-view, simultaneous, non-synced, markerless video.
We are in the process of quantifying the error between our reconstructed video and the actual 3D motion (from 6-view, simultaneous, synced, marker video). We are also in the process of identifying the sources of error and trying to reduce them to see how accurate we can push this procedure.
