1. A system for visual inspection and three-dimensional (3D) measurement of a honeycomb body, the system comprising:
at least one roller supporting the honeycomb body, the roller configured to enable the honeycomb body to rotate continuously over at least a portion of a full rotation of the honeycomb body about an axis of rotation;
at least one camera having a first field of view encompassing an inspection region of an outer circumferential surface of the honeycomb body;
a travel sensor that measures circumferential travel along the outer circumferential surface of the honeycomb body when the honeycomb body is rotated by the at least one roller; and
a first edge sensor configured to inspect a first circumferential edge of the honeycomb body; or
at least one 3D line sensor configured to inspect and obtain height data associated with the outer circumferential surface of the honeycomb body;
wherein the travel sensor is configured to initiate inspection by the at least one camera and at least one of the first edge sensor or the at least one 3D line sensor at a predetermined increment of circumferential travel.
