Claim One:
1. An apparatus for inspecting and measuring an object to be measured, the apparatus comprising: a distance measurement device includes a light projection unit that projects a two-dimensional optical pattern onto a measurement target of an object to be measured, a plurality of imaging units, disposed in a stereoscopic arrangement, that image the measurement target of the object to be measured, and a driving unit configured to rotate a posture of at least one of the imaging units to control a parallax angle between the imaging units; a working distance control device that controls the driving unit and adjusts a position at which optical axes of the imaging units intersect; and a distance calculation device includes a correspondence position calculation unit that determines a correspondence position at which the same region among images of the imaging units disposed in a stereoscopic arrangement is imaged, and a distance calculation unit that calculates a distance to a measurement target of an object to be measured based on a calculation result of the correspondence position calculation unit.
