Shape measuring device

A shape measuring device comprising:

• a first light radiating unit to radiate first line light and second line light, the first line light being linear light, the second line light being linear light:
• a first image capturing unit having a first field of view, to capture an object passing through a first measurement region, and to capture the object passing through a second measurement region different from the first measurement region, the first measurement region being a region where a first plane through which the first line light passes and the first field of view intersect with each other, the second measurement region being a region where a second plane through which the second line light passes and the first field of view intersect with each other, the second measurement region being located on the first light radiating unit side from the first measurement region;
• and
• a measuring unit to measure a shape of the object on a basis of a first image that is an image of a part of the object passing through the first measurement region and second images that are images of parts of the object passing through the second measurement region, the part of the object passing through the first measurement region being irradiated with the first line light, the parts of the object passing through the second measurement region being irradiated with the second line light.
