1. A three-dimensional (3D) positioning apparatus for an object that includes a plurality of feature points, a reference point being formed by the feature points, the object undergoing movement from a first position to a second position, said 3D positioning apparatus comprising:

  • an image sensor for capturing images of the object; and

    a processor coupled to said image sensor for receiving and processing the images captured thereby, said processor being configured to calculate on the basis of the images initial coordinates of each of the feature points when the object is in the first position, initial coordinates of the reference point when the object is in the first position, final coordinates of the reference point when the object is in the second position, and final coordinates of each of the feature points when the object is in the second position;

    wherein said processor is further configured to calculate 3D translational information of the feature points on the basis of the initial and final coordinates of the reference point; and

    wherein said processor is further configured to calculate 3D rotational information of the feature points on the basis of the initial and final coordinates of each of the feature points.
