Abstract
An image inspection apparatus includes: an image capturing unit which captures images of an object; a transparent illumination unit which has a light-emitting surface which radiates light to the object and is configured to be able to control a light-emitting position on the light-emitting surface and a radiation direction of the light; and a control unit which is configured to control the image capturing unit and the illumination unit. The control unit causes the illumination unit to change the light-emitting position and the radiation direction, causes the image capturing unit to capture images of the object, identifies a light-emitting position and a radiation direction of the illumination unit when a measurement point of the surface of the object is illuminated from images of the object, and calculates a distance to the measurement point on the basis of the identified light-emitting position and the identified radiation direction.
