Abstract: Imaging-based methods for detecting defects in an extruded cellular ceramic article having a web array are disclosed. The methods may include capturing a digital image of the web array to establish an intensity-based initial web array representation. The methods also may include performing an intensity threshold process on the initial web array representation to define an intensity-based high-resolution web array representation having sub-pixel resolution, and performing piecewise cubic spline fits to define corresponding web skeletons. The method may also include comparing intensities of the high-resolution web array representation along the web skeletons to a threshold intensity to determine the defect locations and sizes. The methods can be applied to determining the size and location of skin defects as well.

Abstract: Improved inspection techniques are described herein for checking for the presence of and identifying surface defects on a honeycomb body. The improved inspection utilizes measurement of travel of an outer surface of the honeycomb body to collect images of the outer surface. The images are combined into a composite image showing the outer surface of the honeycomb body. The composite image is analyzed to identify surface defects.

Abstract: Methods of inspecting cellular articles such as cellular ceramic articles are disclosed, wherein the methods comprise characterizing a web structure from intensity values of a digital image. One method comprising establishing an edge location for each of the walls of the web, and an edge intensity slope SE for each edge location, and then searching for a wall intensity slope SW in one of the web walls of the characterized web structure to determine the location of a web defect. Another method involves determining at least one characteristic that defines a conforming cell, then identifying a non-conforming cell region based on the at least one characteristic, and then examining the walls within the non-conforming cell region to locate the defect in one of the walls within the non-conforming cell region.

Abstract: An apparatus and method to align ceramic honeycomb bodies. The apparatus includes a light source to direct light toward a first end of a ceramic honeycomb body, a lens to receive at least a portion of the light directed to the first end of the ceramic honeycomb body, an imaging device to capture an image of the received light, wherein the image comprises a portion of a side surface of the honeycomb body. The apparatus comprises a controller configured to receive the captured image, to analyze the captured image based on the portion of the side surface, to adjust the ceramic honeycomb body and/or the lens based on the analysis to align the ceramic honeycomb body and the lens optical axis.
