Embodiment 1

[0044] like figure 1 As shown, the off-axis virtual image plus stereoscopic display system of the present invention includes a projector 1 , an optical front reflector 2 , a front projection screen 3 , and a spherical reflector 4 . Wherein, the projector 1 , the optical front reflector 2 and the front projection screen 3 are arranged on the centripetal concave side of the spherical reflector 4 from top to bottom.

[0045] Specifically, the projection direction of the projector 1 has an included angle with the mirror surface 2 of the optical front reflector. The front projection screen 3 is placed at one focal length of the spherical reflector 4 , so that the light projected by the projector 1 can shine on the front projection screen 3 after being reflected by the optical front reflector 2 . The light reflected by the front projection screen 3 is projected on the spherical reflector 4, and can be figure 1 An upright magnified virtual image is formed at the eye point in the ce...

Embodiment 2

[0060] like figure 2 As shown, another off-axis virtual image plus stereoscopic display system embodiment of the present invention mainly includes a projector 1, a rear projection screen 9, and a spherical mirror 4; wherein, the projector 1 and the rear projection screen 9 are arranged from top to bottom On the centripetal concave side of the spherical reflector 4; specifically, the rear projection screen 9 is placed at one focal length of the spherical reflector 4, and the light projected by the projector 1 can shine on the rear projection screen 9; The light on the screen 9 is projected on the spherical reflector 4, and can form an upright magnified virtual image at the eye point 5; In addition; in the close-range display stage, the projector 1 projects stereoscopic images.

[0061] The present invention can be applied to the visual display system of the air refueling / receiving aircraft simulator, and the specific implementation is as follows.

Abstract

The invention discloses an off-axis virtual image plus stereoscopic display system, which mainly comprises a projector, an optical front reflector, a front projection screen and a carbon plastic spherical reflector, wherein the optical front reflector, the projector and the front projection screen are arranged on a centripetal concave surface side of the carbon plastic spherical reflector from top to bottom; an eyespot is arranged below the front projection screen, and is outside one time of focal length of the carbon plastic spherical reflector; and the projector projects stereoscopic images in a close shot display stage. Accordingly, the invention further discloses an off-axis virtual image plus stereoscopic display method. The off-axis virtual image plus stereoscopic display system adopts the hard carbon plastic spherical reflector, reduces the manufacturing cost, improves the space utilization rate, is small in image distortion, and further has the advantage of being cleanable. The off-axis virtual image display system plus stereoscopic display increases the close-shot depth of field in a mirror surface of a simulator visual display system, and makes the sense of depth of field of the simulator visual display system stronger.

Description

technical field [0001] The invention belongs to the technical field of visual optics of a simulation system, and in particular relates to an off-axis virtual image plus stereoscopic display system and method. Background technique [0002] In the visual display of the simulator, there are mainly two ways of real image display and virtual image display. [0003] Real image display refers to projecting the projector image on a diffuse screen, and people directly observe the screen image, similar to the combination of a movie projector and a projection screen. The advantage of real image display is that the field of view is larger, and the disadvantage is that the sense of depth of field is poor. [0004] Virtual image display refers to placing an object at one focal length of the optical element to form an upright and magnified virtual image in the distance, similar to looking in a mirror (without optical power, a virtual image of equal size). According to the relative positi...
