Abstract
A distortion inspecting apparatus, which inspects perspective distortion of a transparent object, includes a projector that projects a plurality of display points arranged at predetermined intervals, a screen that displays an image projected by the projector thereon and allows the image to pass therethrough, a pedestal that disposes the transparent object at a position where the image passed through the screen, a camera that captures the image that passed through the transparent object, and a control device that stores a reference position coordinate of the image that passed through a reference transparent object, compares the reference position coordinate with an inspection position coordinate of the image that passed through the transparent object as an object to be inspected, and calculates a displacement quantity of the reference position coordinate.
