A method of measuring features of a workpiece comprising a honeycomb body or a honeycomb extrusion die, the method comprising: providing an imaging system; capturing an image (670; 770) of a first portion of the workpiece, wherein the image (670; 770) of the first portion of the workpiece defines a frame of reference; calculating a first plurality of measurements based at least in part on the image (670; 770) of the first portion of the workpiece; capturing an image (672; 772) of a second portion of the workpiece, wherein the first portion of the workpiece and the second portion of the workpiece comprise a plurality of common features, wherein the second portion comprises at least one feature that is not included in the first portion of the workpiece; calculating a second plurality of measurements based at least in part on the image (672; 772) of the second portion of the workpiece, characterized in that the first and second pluralities of measurements correspond to dimensions of intersecting walls of the honeycomb body or of intersecting slots of the honeycomb extrusion die, wherein at least one of the first plurality of measurements is a first reference dimension defined by the common features, wherein at least one of the second plurality of measurements is a second reference dimension defined by the common features, wherein the first reference dimension is defined by a dimension between the common features based at least in part on the image (670; 770) of the first portion of the workpiece and the second reference dimension is defined by the same dimension between the common features based at least in part on the image (672; 772) of the second portion of the workpiece; comparing the first reference dimension to the second reference dimension to calculate a transformation; applying the transformation to the second plurality of measurements to convert the second plurality of measurements into the frame of reference; and combining the first plurality of measurements and the converted second plurality of measurements. providing an imaging system; capturing an image (670; 770) of a first portion of the workpiece, wherein the image (670; 770) of the first portion of the workpiece defines a frame of reference; calculating a first plurality of measurements based at least in part on the image (670; 770) of the first portion of the workpiece; capturing an image (672; 772) of a second portion of the workpiece, wherein the first portion of the workpiece and the second portion of the workpiece comprise a plurality of common features, wherein the second portion comprises at least one feature that is not included in the first portion of the workpiece; calculating a second plurality of measurements based at least in part on the image (672; 772) of the second portion of the workpiece, characterized in that the first and second pluralities of measurements correspond to dimensions of intersecting walls of the honeycomb body or of intersecting slots of the honeycomb extrusion die, wherein at least one of the first plurality of measurements is a first reference dimension defined by the common features, wherein at least one of the second plurality of measurements is a second reference dimension defined by the common features, wherein the first reference dimension is defined by a dimension between the common features based at least in part on the image (670; 770) of the first portion of the workpiece and the second reference dimension is defined by the same dimension between the common features based at least in part on the image (672; 772) of the second portion of the workpiece; comparing the first reference dimension to the second reference dimension to calculate a transformation; applying the transformation to the second plurality of measurements to convert the second plurality of measurements into the frame of reference; and combining the first plurality of measurements and the converted second plurality of measurements.
