ABSTRACT:
A shape-measuring device1measures the shape of a object to be measured1in which segments are arranged and bonded in rows while relatively moving the object1in one direction. The shape-measuring device includes rollers31provided corresponding to the rows of segments and displaced to follow unevenness of an end face1aof the object while being rotated on the end face1adue to the relative movement, detection means35provided corresponding to each roller31and detecting the amount of displacement of each roller31, and calculation means37for calculating shape data of the object1based on the amount of displacement of the roller31detected by the detection means35. The shape-measuring device1can accurately and promptly measure the shape of the object such as a DPF in which segments are bonded in rows.
