Description

Technical Field

[0001] This invention belongs to the field of AR device technology, and specifically relates to an AR image generation device. Background Technology

[0002] AR stands for Augmented Reality, referring to augmented reality technology. Currently, the content displayed on AR glasses primarily comes from externally connected mobile phones, computers, or resources within their built-in processing units. For real-time external content, it can only be captured by the AR glasses' camera. Therefore, how to achieve magnified real-time content display in AR glasses is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0003] The present invention aims to at least partially solve the aforementioned technical problems. Therefore, the objective of the present invention is to provide an AR image generation apparatus.

[0004] The technical solution adopted in this invention is as follows:

[0006] The imaging module includes a lens, a prism located behind the lens, a photosensitive element located in the output light path of the prism, and a display screen electrically connected to the photosensitive element. The output light of the display screen is directed toward the first glass.

[0007] Alternatively, the imaging module includes a telescope, a first reflecting mirror located behind the telescope, and a magnifying glass located in the output light path of the first reflecting mirror, with the output light of the magnifying glass directed toward the first glass.

[0008] Preferably, a processing chip is provided between the photosensitive element and the display screen. The output image of the photosensitive element includes one or more light sources. The processing chip cuts the output image into a corresponding number of images according to the number of light sources.

It is only for the convenience of describing the present invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the AR image generation device of this embodiment includes a frame 1, with a first glass 4 inclined at 45° inside the frame 1. An image module 2 and temples 3 are mounted on the frame 1. The image module 2 includes a housing 16, which is detachably connected to the frame 1. A lens 5 is mounted on the housing 16, and a photosensitive element 7, a display screen 8, and a processing chip 9 are disposed inside the housing 16. The lens 5 is positioned facing forward, and a prism 6 inclined at 45° is located behind the lens 5. The photosensitive element 7 is located on the output light path above the prism 6. Both the photosensitive element 7 and the display screen 8 are electrically connected to the processing chip 9, and the display screen 8 is positioned facing the first glass 4.

[0031] After light enters the lens 5, it is reflected by the prism 6 to the photosensitive element 7. The reflectivity of the prism 6 is 7% to 30%, which can effectively reduce the reflection of weak light and only reflect strong light. After the strong light image is reflected to the photosensitive element 7, the strong light image is finally output to the display screen 8 for display. The output light of the display screen 8 can be directly directed to the first glass 4 and enter the human eye after being reflected by the first glass 4. The reflectivity of the first glass 4 is 7% to 80%. The human eye can directly observe the front through the first glass 4. The image that enters the human eye after reflection overlaps with the real image directly observed in front of the first glass 4, realizing the AR effect.

[0032] The AR image generation device is used to observe one or more pre-set peripherals, each of which is a strong light source. Each frame of the output image from the photosensitive element 7 includes one or more light sources. The processing chip 9 cuts the output image into a corresponding number of images according to the number of light sources. Each image only includes the display content of the light source; that is, the boundary of each image is the boundary of the light source. Each image is treated as a layer and magnified according to the center of the light source. The magnified layers are then overlapped and merged again according to the light sources from near to far to form a new image, which is then output to the display screen 8. Figure 4 As shown, the AR image generation device observes three peripherals of the same size. Each peripheral is a circular light source. The output image of the photosensitive element 7 includes the three light sources. The processing chip 9 magnifies the three layers individually by the same factor and then merges them into a new image to realize the AR display of the three light sources. Since each light source is magnified as a separate layer, the magnification does not affect the deformation of the other light sources. Because the light sources are magnified and then overlapped from near to far, the magnified images of some light sources are partially obscured, which creates a more three-dimensional visual effect while magnifying.

[0033] In other embodiments, when the output image of the photosensitive element 7 has only one light source, the processing chip 9 cuts it into an image according to the boundary of the light source. This image is then magnified as a layer, and the magnified layer is the new image.

[0034] The processing chip 9 is connected to a wired interface and a wireless unit. The wired interface can be a USB interface. Images can be input to the processing chip 9 through the USB interface and projected onto the first glass 4 via the display screen 8 and reflected into the human eye. Similarly, the wireless unit can communicate with the terminal to realize wireless image input.

[0035] The housing 16 also houses a rechargeable battery, which powers components such as the photosensitive element 7, the display screen 8, and the processing chip 9. The photosensitive element 7 may be a CMOS photosensitive element.

[0036] Example 2

[0037] like Figure 1 and Figure 3 As shown, the AR image generation device of this embodiment, based on the AR image generation device of embodiment two, adds a magnifying glass 13, a periscope and a polarizer 10.

[0038] Specifically, lens 5 is located inside housing 16, and a periscope is located in front of lens 5. A polarizer 10 is located in front of the periscope. The periscope includes a second reflector 11 and a second glass 12 arranged in parallel. After light enters through polarizer 10, it is reflected by the second reflector 11 and the second glass 12 in sequence before entering lens 5. Magnifying glass 13 is located between display screen 8 and first glass 4.

[0039] The AR image generation device in this embodiment can be used to directly observe the polarized light output by the LCD screen. The polarized light output by the LCD screen cannot be directly recognized by the human eye. The polarized light is converted into light that can be recognized by the human eye through the polarizer 10. The reflectivity of the second glass 12 is 7% to 80%, which is used to filter out some weak light. Then it enters the lens 5, passes through the prism 6 and is recognized by the photosensitive element 7, then is displayed on the display screen 8, and after being magnified by the magnifying glass 13, it finally enters the human eye after being reflected by the first glass 4 and is recognized.

[0040] The magnifying glass 13 setting allows the LCD screen to be set to a smaller size, while the final image can still maintain a large size after being magnified.

[0041] Example 3

[0042] like Figure 1 and Figure 5 As shown, the AR image generation device of this embodiment includes a frame 1, with a first glass 4 inclined at 45° inside the frame 1. An image module 2 and a temple 3 are mounted on the frame 1. The image module 2 includes a housing 16, which is detachably connected to the frame 1. A polarizer 10 is provided on the housing 16. A telescope 14, a first reflector 15, and a magnifying glass 13 are provided inside the housing 16. The telescope 14 is located behind the polarizer 10, the first reflector 15 is located behind the telescope 14, and the magnifying glass 13 is located in the output optical path below the first reflector 15. The output light of the magnifying glass 13 is directed towards the first glass 4.

[0043] The AR image generation device in this embodiment can be used to directly observe the LCD screen. The polarized light output by the LCD screen cannot be directly recognized by the human eye. The polarized light is converted into light that can be recognized by the human eye through the polarizer 10. After being magnified by the telescope 14, it is reflected by the first reflecting mirror 15 to the magnifying glass 13. After being magnified again, it is reflected by the first glass 4 and enters the human eye for recognition. The reflectivity of the first glass 4 is 7% to 80%. The human eye can directly observe the front through the first glass 4. The image that enters the human eye after reflection overlaps with the image directly observed in front of the first glass 4, thus achieving the AR effect.

[0044] The image module 2 includes markers located below the telescope 14 and the polarizer 10, and in front of the first glass 4. The markers allow the user to clearly see which part of the light is blocked and is magnified by the AR image generation device and transmitted to the user's eyes.

[0045] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
