Image measurement device

An image measurement device which has a first measurement region acquisition circuitry for acquiring a first measurement region from an image and a second measurement region acquisition circuitry for acquiring a second measurement region, which is different from the first measurement region, from the image, and computes a distance between the first measurement region and the second measurement region from distance information corresponding to the first measurement region and distance information corresponding to the second measurement region, the image measurement device comprising:

• a distance computation circuitry that, after the first measurement region positioned on a first object is displaced so as to be a region on the first object in response to an operation from an input circuitry that causes the first measuring region to be displaced on the image and the second measurement region positioned on a second object is displaced in a region on the second object in accordance with an operation of a linear region following circuitry or a plane region deciding circuitry that causes a contour or a plane on the image, at which the second measurement region is positioned to be displaced, computes a distance between the first measurement region after the displacement and the second measurement region after the displacement, which is displaced by the linear region following circuitry or the plane region deciding circuitry,
• in a case where a plurality of edge components are detected in the same region at a time of displacing a measurement point, a spatially close edge is being extracted based on three-dimensional information acquired from a first three-dimensional measurement region acquisition circuitry and a second three-dimensional measurement region acquisition circuitry and being judged as a continuous edge.

An image measurement device, comprising:

• an input circuitry via which a region of an image is designated;
• a first measurement region acquisition circuitry configured to acquire a first measurement region based on a first region designated via the input circuitry;
• a second measurement region acquisition circuitry configured to acquire a second measurement region based on a second region designated via the input circuitry;
• a distance computation circuitry configured to compute a real-space distance between the first measurement region and the second measurement region;
• and
• a plane region deciding circuitry configured to determine a plane region of the image,
• in accordance with an operation, inputted via the input circuitry, of displacing the first measurement region on a first object on which the first measurement region has been positioned, (i) the first measurement region acquisition circuitry acquiring a displaced first measurement region, (ii) the second measurement region acquisition circuitry acquiring a displaced second measurement region by displacing the second measurement region on a second object on which the second measurement region has been positioned, and (iii) the second measurement region being displaced on continuous planes, which are determined by the plane region deciding circuitry, so as to be the displaced second measurement region,
• the distance computation circuitry being configured to compute a real-space distance between the displaced first measurement region and the displaced second measurement region.
