[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a virtual reality device provided in an embodiment of this application. The virtual reality device 500 is used to implement virtual reality functions and is applied in a device with virtual reality functions.

[0025] The virtual reality device 500 includes a main camera 10, a periscope module 20, and an infrared module 30, wherein the main camera 10 is located between the periscope module 20 and the infrared module 30.

[0027] Furthermore, the main camera 10 is used to capture images, that is, to capture a first image of the scene to be captured. The main camera 10 can be a color camera, which has high-definition characteristics and can capture high-definition first images.

[0028] The periscope module 20 is used for imaging, and the periscope module 20 can achieve zoom shooting and can capture a second image of the scene to be shot.

[0029] In the embodiments of this application, the periscope module 20 includes a prism 21, a telephoto assembly 22, a filter 23, and an imaging chip, and the prism 21, the telephoto assembly 22, the filter 23, and the imaging chip 24 are arranged sequentially.

[0030] The prism 21 is located on the periscope module 20 near the main camera 10, that is, the main camera 21 is located between the prism 21 and the infrared module 30.

[0031] The prism 21 is used to achieve optical path folding, that is, to fold the light rays along their path. Optionally, the prism 21 can be a polarizing beam splitter, a right-angle prism, or other types and structures.

[0032] In the embodiments of this application, the prism 21 is set as one. In other embodiments, the prism 21 may be set as multiple. The embodiments of this application do not limit the type, structure and number of prisms 21.

[0033] The telephoto component 22 can achieve long focal length shooting, as well as identify and track target objects. The scene component 22 can be regarded as a telephoto lens.

[0034] The telephoto component 22 includes a first lens 221, a second lens 222, a third lens 223, a fourth lens 224, and a fifth lens 225, which are arranged in sequence.

[0035] The second lens 222, the third lens 223 and the fourth lens 224 are located between the first lens 221 and the fifth lens 225. The first lens 221 is located close to the prism 21 and the fifth lens 225 is located away from the prism 21.

[0036] In the embodiments of this application, the first lens 221, the second lens 222, the third lens 223, the fourth lens 224, and the fifth lens 225 are all provided as one. The first lens 221 is a coated plano lens, the second lens 222 is a convex lens, the third lens 223 is a convex lens, the fourth lens 224 is a concave lens, and the fifth lens 225 is a convex lens.

[0037] Optionally, in other embodiments, the first lens 221, the second lens 222, the third lens 223, the fourth lens 224, and the fifth lens 225 may be configured in other quantities. Furthermore, the lens type and setting position of the first lens 221, the second lens 222, the third lens 223, the fourth lens 224, and the fifth lens 225 may be changed, as long as they meet the setting purpose of the telephoto component 22 in this application.

[0038] The filter 23 is used to select the required radiation band and is positioned close to the fifth lens 225, that is, the fourth lens 224 and the filter 23 are located on opposite sides of the fifth lens 225.

[0039] In manufacturing, the filter 23 is made of plastic or glass sheet with added special dyes. It has various types and functions, such as transparent filter, red filter, reflective filter, spectrophotometer, and cutoff filter, etc.

[0040] In the embodiments of this application, the filter 23 is an IR filter, which is an infrared filter. According to the wavelength specifications of the lens, it can block and filter visible light from passing through, while allowing infrared light to pass through. It can separate the infrared effect in a light environment where visible light and infrared light are mixed.

[0041] Optionally, the filter 23 can be positioned at a distance from the telephoto assembly 22, or the filter 23 can be attached to the telephoto assembly 22.

[0042] In the embodiments of this application, the filter 23 is configured as one; however, in other embodiments, the filter 23 may be configured as multiple.

[0044] The imaging chip 24 is either a CCD or a CMOS. A CCD is made of a highly sensitive semiconductor material that converts light into electrical charges, which are then converted into digital signals by an analog-to-digital converter chip. These digital signals are compressed and stored in a memory or internal hard drive. A CMOS chip primarily utilizes silicon and germanium, allowing N-level and P-level semiconductors to coexist. The current generated by these complementary effects can be recorded and interpreted into an image by the processing chip.

[0045] In the embodiments of this application, the imaging chip 24 is set to one. In other embodiments, the imaging chip 24 may be set to multiple. Furthermore, this application does not limit the type of the imaging chip 24, as long as it meets the imaging purpose.

[0046] The infrared module 30 is used for imaging and can capture a third image of the scene to be captured, belonging to infrared photography.

[0047] Infrared photography is a shooting method that uses infrared sensors and infrared filters to take pictures that are different from traditional black and white color photos. In addition, infrared light has the ability to penetrate some materials and clothing compared to visible light.

[0048] In the embodiments of this application, the infrared module 30 includes an infrared camera 31 and an infrared fill light chip 32, wherein the infrared camera 31 is located close to the main camera 10, that is, the infrared fill light chip 32 and the main camera 10 are located on two opposite sides of the infrared camera 31.

[0049] The infrared camera 31 can sense the spectral characteristics of infrared light, or the infrared camera 31 can sense infrared light.

[0050] The infrared fill light chip 32 is used to provide fill light, assisting the infrared camera 31 in capturing the third image of the scene to be captured.

[0051] In the embodiments of this application, each infrared camera 31 and infrared filler chip 32 is set to one. In other embodiments, the infrared camera 31 and / or the infrared filler chip 32 may be set to multiple. In the embodiments of this application, the number of infrared cameras 31 and infrared filler chips 32 is not limited, as long as they meet the purpose of infrared imaging.

[0052] The virtual reality device 500 of this application embodiment, when used by a user, can utilize the main camera to fill the perimeter of the screen and blur it, while the telephoto camera is displayed in the center of the screen, thereby ensuring a full sense of immersion for the user in the closed VR environment. For example, when the virtual reality device 500 is used in a VR device and operated by the user, when the user turns on the camera, the main camera works, and the camera signal is projected onto the display screen. When the user activates a zoom command for a specific location, the periscope camera is invoked, the image is projected to the center of the display screen, and the main camera performs pixel magnification to fill the perimeter of the display screen.

[0053] It is understood that, in addition to the main camera 10, periscope module 20 and infrared module 30 mentioned above, the virtual reality device 500 of this application embodiment may also include other optical structures. For example, the virtual reality device 500 may also include a distance sensor or a light sensor, which will not be described in detail here.

[0054] Furthermore, this application embodiment also provides a virtual reality device (not shown in the figure), which is a device with virtual reality function, such as VR glasses, or a 3D scanner, etc.

[0055] The virtual reality device includes the virtual reality unit 500, through which virtual reality projects are implemented. The virtual reality device also includes a mounting housing for mounting the virtual reality unit 500.

[0056] When the virtual reality device is VR glasses, the mounting housing can be a mask, and the mask is equipped with a headband for the user to wear. When the user wears the VR glasses, the mask and the user's eyes are in a relative position. The virtual reality device 500 is mounted inside the mask, so that the virtual reality device 500 and the user's eyes are in a relative position, allowing the user to realize virtual reality projects through the VR glasses.

[0057] When the virtual reality device is a 3D scanner, the mounting housing is the part of the scanner used for scanning. For example, the mounting housing is a shell with a handheld structure that has a scanning function. The virtual reality device 500 is mounted in the shell and is used by the user to perform scanning by hand.

[0058] Optionally, the virtual reality device should also include a display screen for displaying images captured by the virtual reality device 500.

[0059] Optionally, the virtual reality device can be other devices with virtual reality functionality, and the virtual reality device may also include other structures, which will not be described in detail here.

The periscope module 20 includes a prism 21 and a telephoto lens 22. The prism 21 is located close to the main camera 10 and is used to fold the optical path. The telephoto lens 22 is used to magnify the optical path. This arrangement allows multiple cameras to display images on the same screen, creating a mixed imaging effect and thus improving the device's display quality.

[0061] Furthermore, the virtual reality device 500 also includes an infrared module 30, which and the periscope module 20 are located on opposite sides of the main camera 10. The main camera 10, the periscope module 20 and the infrared module 30 can display the images they capture on the same screen to enhance the mixed imaging effect.
