Abstract
The present invention relates to a dimension measuring device and a dimension measuring method, the dimension measuring device comprising: a moving unit for moving two sheets of material; a plurality of range finders installed at a preset interval along the direction of traveling of the material, so as to measure the distance from the side surfaces of the material; and an imaging device installed to take images between the first and second range finders, which are installed at the first and second locations with reference to the entry side of the material, respectively.
Claims11
A dimension measuring device comprising:
- a moving unit for moving two sheets of material;
- a plurality of range finders installed at a preset interval along a direction of traveling of the material, while being spaced from both side surfaces of the material, so as to measure a distance from the side surfaces of the material;
- and
- an imaging device installed to take images between first and second range finders, which are installed at first and second locations based on an entry side of the material, respectively.
A dimension measuring method comprising:
- moving two sheets of material;
- measuring a distance from side surfaces of the material using a plurality of range finders arranged at a preset interval along a movement direction of the material;
- taking images of the material using an imaging device;
- and
- measuring a length, a width, a camber and perpendicularity of each of the two sheets of the material using distance information measured by the plurality of range finders and images of the material taken by the imaging device.
