1. A locating method for a component, the component having an exterior surface, the method comprising: locating a surface feature configured on the exterior surface along an X-axis and a Y-axis by analyzing an image of the component to obtain X-axis data points for the surface feature relative to the component and Y-axis data points for the surface feature relative to the component; directly measuring the surface feature along a Z-axis to obtain Z-axis data points for the surface feature, wherein the X-axis, the Y-axis and the Z-axis are mutually orthogonal; calculating a pitch angle for the surface feature based on the X-axis data points for the surface feature relative to the component and the directly measured Z-axis data points; and calculating a roll angle for the surface feature based on the Y-axis data points for the surface feature relative to the component and the directly measured Z-axis data points.
