Unweighting System for Reducing Gravity Using a Camera

An unweighting system for reducing the gravity load of a subject due to the weight acting along a first axis, said unweighting system comprising:

• a support structure;
• a motor;
• and a movement system of said subject mounted on said support structure,
• wherein said movement system includes the following elements:
• a first rail and a second rail parallel to a second axis and integral with said support structure;
• a third rail parallel to a third axis perpendicular to said second axis, wherein said third rail extends between said first rail and said second rail and is configured to slide along said first and second rails so as to move along said second axis;
• a sliding element configured to slide along said third rail in the direction of said third axis;
• a cable associated with said sliding element and driven by said motor to reduce the gravity load of said subject;
• a support element for said subject, associated with said cable;
• wherein said first axis, said second axis and said third axis form a Cartesian coordinate system,
• wherein said unweighting system further comprises a camera, for example a camera of the RGB, RGB-Depth or Depth type, and an electronic board configured to locate the position of a plurality of articular joints of said subject in space by means of markerless technology on the basis of the data acquired by said camera;
• and
• wherein said support structure is placed on a base in contact with the ground and said unweighting system further comprises a plurality of sensors, for example force and/or pressure sensors, for determining a weight applied by said subject on said base.
