Method and device for measuring hud ghost image

Abstract

An optical characteristic measurement method according to embodiments may comprise the steps of: generating multi-view images, the multi-view images including a left image, a central image, and a right image; displaying the position of a virtual image for the multi-view images; calculating the depth of the position of the virtual image; estimating the depth of the virtual image; matching the depth of the position to the depth of the virtual image; and calibrating errors between the multi-view images on the basis of the matched depth. Additionally, the optical characteristic measurement method may comprise the steps of: generating multi-view images, the multi-view images including a left image, a central image, and a right image; displaying the positions of virtual images for the multi-view images; estimating the depths of the positions of the virtual images; grouping the positions on the basis of the depths; selecting some positions from the grouped positions; and projecting a corrected virtual object on the basis of the selected positions and the depths.
