1. A calibration system for a prosthetic device testing apparatus, the calibration system comprising:
a calibration device configured to be positioned within a test chamber of the prosthetic device testing apparatus, the calibration device including:
a plurality of walls spaced from each other and each extending radially outward from a central portion of the plurality of walls to a respective end portion of the wall, each of the plurality of walls extending axially to a respective top surface of the wall, and
a plurality of indicators on at least one of the plurality of walls, the plurality of indicators configured to be at a defined real distance between each other, the defined real distance configured to be utilized to determine a scaling between an image distance of one or more images of the prosthetic device and a real distance; and
one or more cameras configured to image the plurality of indicators to provide an image distance between the plurality of indicators, the image distance between the plurality of indicators being utilized to determine the scaling.
