gaussian formula imaged by optical system:
1/image distance-1/object distance is 1/focal length
The derivation can be found as follows:
image distance (object distance focal length)/(object distance focal length)
In the invention, an imaging surface of a micro display is imaged through a liquid lens, the distance between the imaging surface and the micro display is fixed, so that the object distance is basically a constant value, the image distance can be changed by changing the voltage applied to the liquid lens and further adjusting the focal length of the liquid lens, and the optical axis of the liquid lens is vertical to the display area of the micro display or is vertical to the display area of the micro display after being bent by reflection; the light splitting plate is arranged on one surface of the shell and plated with a light splitting film, and one side with the light splitting film is close to human eyes; the surface of the light splitting plate plated with the light splitting film is not parallel to the optical axis of the liquid lens and is used for reflecting light rays from the micro display and passing through the liquid lens to human eyes, so that the human sees a two-dimensional image which is amplified by the liquid lens and imaged on the micro display at a certain distance, and meanwhile, the light splitting film of the light splitting plate has a certain transmittance, so that the human can see a real environment through the plate; the light emitted by the micro display enters human eyes after being refracted by the liquid lens and reflected by the light splitting flat plate, so that a human can see a virtual image which is displayed by the micro display, amplified by the liquid lens and imaged at a certain distance; meanwhile, the light splitting film of the light splitting plate has a certain transmittance, and people can see the real environment through the plate, so that the aim of superposing the virtual image and the real environment is fulfilled, and the augmented reality is realized;
in summary, because the depth images in different depth ranges are displayed at different distances within the human visual persistence time, for the human visual perception, the method is equivalent to simultaneously seeing two-dimensional images at different distances, each two-dimensional image is an image in the depth range corresponding to the distance, and has stronger stereoscopic impression, so that the displayed content (object) is closer to the scene of the real world; the display device can realize clear display of a stereoscopic scene, and can see an external real scene through the light splitting flat plate, thereby realizing augmented reality stereoscopic display.

In practical use, due to the fact that the distance between eyes of a user and the distance between two eyes and the nose bridge are different, when the augmented reality stereoscopic display device is used, effect difference exists, and therefore in the scheme, in order to reduce the difference, the transparent plate body is arranged into a whole instead of two lenses corresponding to eyes of the user; in addition, because the transparent plate body needs to form an included angle smaller than 90 degrees with the liquid lens, in order to improve the use experience of all users, the angle of the transparent plate relative to the liquid lens can be adjusted through the arrangement of the first fixing piece and the second fixing piece in the scheme, and the adjusted angle does not need to be too large, such as 5 degrees, 10 degrees, 15 degrees, or 20 degrees and the like (the length of a corresponding rack can be set to be 0.5cm, 1cm, 1.5cm or 2 cm); the process is realized by manually rotating a gear shaft to drive a gear to move on a rack, and in the moving process, the gear shaft slides in the strip-shaped through hole; the rubber pad plays a role in buffering and increasing a certain friction force, assists in fixing the gear and the transparent plate body, and prevents the transparent plate body from moving relative to the mirror frame when no external force acts; the second fixing piece mainly provides structural support for the transparent plate body, and the structure of the second fixing piece can also meet the requirement for changing the inclination angle of the transparent plate body within a certain range.
As shown in fig. 5, a display method of an augmented reality stereoscopic display device is described with reference to an example, which takes a depth map displaying a horizontally placed cone with a height of 3m at 2m directly in front of a human eye as an example, as shown in the cone at the upper left part of fig. 5, and the specific display includes the following steps:
step one, dividing the depth map into 3 layers of depth images according to the distance ranges of 2m-3m, 3m-4m and 4m-5m, as shown in the left middle part of the depth map 4;
secondly, projecting each layer of depth image into a two-dimensional image as shown in the lower left part of the figure 5;
step three, displaying the two-dimensional image generated in the step two on the micro display, firstly displaying the two-dimensional image formed by projecting the 2m-3m layer depth image on the micro display, and simultaneously adjusting the voltage of the liquid lens to image the image to the voltage V corresponding to the position 2.5m away from the human eyes2.5So that a virtual image appears 2.5m away from the human eye, as shown in the upper right of fig. 5, the image on the microdisplay and the voltage on the corresponding liquid lens are maintained for 1/72 seconds; then, a two-dimensional image formed by projecting a layer depth image with the depth range of 3m-4m is displayed in the same way, and the two-dimensional image is imaged at a position 3.5m away from human eyes and is maintained for 1/72 seconds, as shown in the right part of FIG. 5; then, a two-dimensional image formed by projecting a layer depth image with the depth range of 4m-5m is displayed in the same way and imaged at a position 4.5m away from human eyes, and the imaging lasts for 1/72 seconds, as shown in the figure5 on the lower right.
And then repeating the third step repeatedly.
Through the steps, because human eyes have a persistence of vision effect, the images displayed in the steps are displayed at the same time, as shown in fig. 6, so that the human feels that one image is arranged at each of the positions of 2.5m, 3.5m and 4.5m, and when the human eyes are focused on one image, the other two images are blurred due to the fact that the human eyes have a certain depth of field range, and the effect of seeing a real object is close to that of seeing the real object.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
