A method of scanning an object includes the steps of: providing a digitizer adapter having at least three markers disposed along a target surface thereof, wherein the digitizer adapter includes a spherical member disposed a predetermined distance at its center point to each of the at least three markers; securing the adapter along an outer surface of the object; creating a plurality of digital images of the object; extracting the coordinates of the at least three markers from the image using photogrammetry; calculating the coordinates of the center point of the spherical member based on the coordinates of the at least three markers; generating surface data by scanning the outer surface of the object and the spherical member; calculating the coordinates of the center point of the spherical member based on at least three points from the surface data of the spherical member; and aligning the center point coordinates to facilitate combining the data from the photogrammetric and surface scan processes.

I claim: 1. A method of scanning an object, said method comprising the steps of: providing a digitizer adapter having at least three dots disposed along a target surface thereof, the at least three dots and the target being colored so as to have a permanent high contrast relative to the target surface, wherein the digitizer adapter includes a ferrous spherical mounting member disposed a predetermined distance from its center point to each of the at least three dots; securing the adapter along an outer surface of the object; creating a plurality of digital images of the object; extracting the coordinates of the at least three dots from the image using photogrammetry; calculating the coordinates of the center point of the ferrous spherical mounting member based on the coordinates of the at least three dots; generating surface data by scanning the outer surface of the object and the ferrous spherical mounting member; calculating the coordinates of the center point of the ferrous spherical mounting member based on at least three points from the surface data of the ferrous spherical mounting member; and aligning the center point coordinates to facilitate combining the data from the photogrammetric and surface scan processes. 2. A method of scanning an object as set forth in claim 1 including the step of securing at least three digitizer adapters along the outer surface of the object, each digitizer adapter having a unique arrangement of markers relative to the other digitizer adapters. 3. A method of scanning an object as set forth in claim 1, wherein the surface scanning process utilizes a laser surface scanner. 4. A method of scanning an object as set forth in claim 1, wherein the surface scanning process utilizes a white light surface scanner. 5. A method of scanning an object as set forth in claim 1 including the step of providing a plurality of dots along the outer surface of the object. 6. A method of scanning an object as set forth in claim 5 including the step of generating a point cloud corresponding to the positions of the dots using photogrammetry.
