Abstract
Laser scanning systems and methods are disclosed herein that can provide quick and efficient measurement of extruded ceramic logs, particularly related to log shape, during manufacture. Two two-dimensional laser scans from respective laser scanners are performed and the resulting laser scan data is combined to form a three-dimensional surface shape measurement of the ceramic log. The systems and methods disclosed herein enable a non-contact measurement of the extruded ceramic log, which reduces the risk of physically damaging the log. The measurement results can be used to adjust the extrusion process of the extruder that forms the extruded ceramic logs.
