ABSTRACT:
Reference or analytic features such as intake and exhaust valves and valve guides are located in an area of a workpiece or part such as a cylinder head, the surface of which is laser scanned to obtain laser scan data. The scan data provides a fine grid of height (Z) values of the part. The part is scanned along lines with constant x or constant y. The method uses a graphical interface and least squares techniques to determine a reference plane for the desired analytic feature. Image processing techniques are then used to extract the desired feature and its boundary. Finally, techniques are used to calculate the precise dimensions of the analytic feature.
