Patent Images

1. A method useful in machine-vision of objects, the method comprising:

  • acquiring a number of images of a first view of a training object from a number of image sensors;

    identifying a number of features of the training object in the acquired at least one image of the first view;

    determining a number of additional views to be obtained based at least in part on the number of image sensors, the number of features identified, the number of features having an invariant physical relationship associated thereto, and a type of the invariant physical relationship associated with the features, sufficient to provide a system of equations and unknowns where the number of unknowns is not greater than the number of equations;

    acquiring at least one image of each of the number of additional views of the training object by the at least one camera; and

    identifying at least some of the number of features of the training object in the acquired at least one image of the number of additional views of the training objectemploying at least one of a consistency of physical relationships between some of the identified features to set up the system of equations; and

    automatically computationally solving the system of equations.
