Abstract
An optical axis direction measurement system includes an aerial image display device, an imaging device, and a measurer. The aerial image display device forms an aerial image as a real image using image light emitted from at least one image display. The imaging device captures the aerial image. The measurer measures an optical axis direction of the aerial image based on captured images of a plurality of imaging portions in an imaging plane of the aerial image.
