Abstract

An imaging device includes: a laser output unit configured to output a plurality of laser beams to be incident on a tool in a direction intersecting a longitudinal direction of the tool; a driving mechanism configured to drive the laser output unit to perform scanning with the plurality of laser beams in the longitudinal direction or a short direction of the tool; and an imaging unit configured to image the tool or a projection image of the tool in a state in which an exposure time in a single imaging is set to correspond to a movement time taken by the driving mechanism to move the laser output unit a predetermined distance.

First claim

What is claimed is:

1 . An imaging device comprising:
a laser output unit configured to output a plurality of laser beams to be incident on a tool in a direction intersecting a longitudinal direction of the tool; a driving mechanism configured to drive the laser output unit to perform scanning with the plurality of laser beams in the longitudinal direction or a short direction of the tool; and an imaging unit configured to image the tool or a projection image of the tool in a state in which an exposure time in a single imaging is set to correspond to a movement time taken by the driving mechanism to move the laser output unit a predetermined distance.

2 . An imaging device comprising:
a laser output unit configured to output a plurality of laser beams to be incident on a tool in a direction intersecting a longitudinal direction of the tool; a driving mechanism configured to drive the laser output unit to perform scanning with the plurality of laser beams in the longitudinal direction or a short direction of the tool; and an imaging unit configured to move the laser output unit a predetermined distance and perform a single imaging of the tool or a projection image of the tool, wherein a width of an image obtained by the single imaging performed by the imaging unit is larger than a width of laser beam irradiation in a moving direction of the laser output unit.

3 . The imaging device according to claim 1 ,
wherein the driving mechanism moves the laser output unit in the longitudinal direction or the short direction of the tool, and wherein the imaging unit images the tool or the projection image of the tool with movement of the laser output unit.

4 . The imaging device according to claim 3 , further comprising:
a display unit configured to display a shape of the tool obtained by processing an image of the tool or the projection image of the tool; wherein the imaging unit performs imaging of the projection image of the tool a plurality of times with the movement of the laser output unit, and wherein the display unit displays, as the shape of the tool, a whole image obtained by combining a plurality of images obtained by the imaging.

5 . The imaging device according to claim 1 , wherein
a relation between an imaging area xo j of each imaging performed with irradiation with each laser beam and an area xc j that cannot be imaged with irradiation with each laser beam is set as expressed by the following formula so as to obtain an image over a whole length of an imaging target portion of the tool:
