[0017] 1.1 Overview

[0018] figure 1 Display system 10 is shown. The display system 10 displays the virtual image 310 superimposed on the object position P410 in the object space 400 . The distance from the viewpoint position P200 of the virtual image 310 to the display position P310 of the virtual image 310 , that is, the display distance is set to be L1 [m]. The distance from the viewpoint position P200 to the target position P410, that is, the maximum value of the target distance is set to L2max[m]. |1 / L1-1 / L2max| is greater than 0 and 0.06 or less.

[0019] In the display system 10, the display distance L1 and the maximum value L2max of the object distance satisfy the relationship of 0<|1 / L1-1 / L2max|≤0.06. Therefore, even if the display position P310 of the virtual image 310 is made closer to the viewpoint position P200 than the object position P410, a person viewing the object space 400 from the viewpoint position P200 can easily recognize that the virtual image 310...

Abstract

An object of the present invention is to provide a display system, a moving object, and a design method capable of reducing the distortion of the virtual image while maintaining the distance from the viewpoint position of the virtual image to the position where the virtual image is superimposed. The display system (10) displays the virtual image (310) at the object position (P410) in the object space (400). The distance from the viewpoint position ( P200 ) of the virtual image ( 310 ) to the display position ( P310 ) of the virtual image ( 310 ), that is, the display distance is set to L1 [m]. The distance from the viewpoint position (P200) to the target position (P410), that is, the maximum value of the target distance is set to L2max [m]. |1 / L1‑1 / L2max| is greater than 0 and less than or equal to 0.06.

Description

technical field [0001] The present disclosure generally relates to a display system, a moving body, and a design method, and more particularly, to a display system, a moving body, and a design method of the display system that project a virtual image into an object space. Background technique [0002] Patent Document 1 discloses a head-up display device that projects a virtual image in front of the front glass of the driver's eyes by projecting video light on the front glass of the vehicle. The head-up display device includes a display element, a movable mirror, a movable portion, a first mirror, and a second mirror. The movable mirror reflects the display light emitted from the display element toward the first mirror. The first reflecting mirror reflects the display light reflected by the movable reflecting mirror toward the second reflecting mirror. The second reflecting mirror reflects the display light reflected by the first reflecting mirror, and condenses the display...
