Claim 7:
8. A computer-implemented method for locating a center of a lug nut comprising:
obtaining a two-dimensional image of a vehicle wheel, the vehicle wheel including a set of lug nuts;
determining an initial center point of at least a first lug nut by processing the two-dimensional image using a first machine learning model;
obtaining a three-dimensional image of at least a portion of the vehicle wheel including the first lug nut;
locating a set of edges at various points around a perimeter of the first lug nut by processing the three-dimensional image using a second machine learning model;
determining a set of distances between a point within the three-dimensional image that corresponds to the initial center point and the located set of edges;
updating the initial center point of the first lug nut based on the determined set of distances; and
mapping a set of two-dimensional coordinates representing the initial center point to a set of three-dimensional coordinates representing the point within the three-dimensional image that corresponds to the initial center point.
