Claim One:
1. An image assessment device assessing an image pair used for 3D measurement from plural captured images comprising: a first captured image selection device that selects a first captured image from the plural captured images; a first captured image information acquisition device that acquires an imaging position and imaging orientation of the selected first captured image; an object distance to-be-measured acquisition device that acquires an object distance to be measured from a first imaging position that is the imaging position for the first captured image to an object to be measured in the first captured image; an object position to-be-measured calculation device that calculates an object position to be measured which is a position on an optical axis in capturing the first captured image and is at the object distance to be measured in a 3D space from the first imaging position; a second captured image selection device that selects a second captured image from the plural captured images; a second captured image information acquisition device that acquires a second imaging position that is an imaging position, imaging orientation, and angle of view for the selected second captured image; an imaging range calculation device that calculates an imaging range corresponding to the second captured image on the basis of the imaging position, imaging orientation, and angle of view for the acquired second captured image; and an assessment device that determines whether or not the calculated object position to be measured is within the calculated imaging range, and assesses that the first captured image and the second captured image are of the image pair if determining that the calculated object position to be measured is within the calculated imaging range.
