[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] like Figure 1 and Figure 2As shown, the present invention provides a vehicle-mounted naked-eye 3D telescopic light field entertainment system, which is specifically installed on the back of the front seat of a family car, or on the back of each row of seats in a large public bus, or on the back of each row of seats in an airplane or a high-speed train. Combined with the special optical path design of the image amplification optical path unit 2, a telescopic large-screen display of the vehicle-mounted screen is realized, and the dizziness problem of watching the screen while the car is driving is solved. Through the real-time follow-up display arrangement mode of the image generation unit 1, it is ensured that the human eye can correctly receive the left and right viewpoint images of the 3D image.
[0037] The above-mentioned vehicle-mounted naked-eye 3D telescopic light field entertainment system specifically includes an image generating unit 1 , an image amplifying optical path unit 2 , a human eye information collecting unit 3 and a data processing unit 4 .
[0038] The image generation unit 1 uses a naked-eye 3D screen as a display image source, and specifically uses a 4.1-inch naked-eye 3D screen as a display image source.
[0039] The image magnifying optical path unit 2 is used to magnify the 3D image generated by the image generating unit 1 to form a large-format image, that is, to make the 3D image displayed by the display image source form a large-format image of more than 50 inches at a distance of about 5 meters.
[0040] The human eye information acquisition unit 3 is installed on the viewing window, specifically a camera, and is used to capture the position information between the viewer and the viewing window, and the pupil distance information between the viewer and the viewing window.
[0041] The data processing unit 4 is connected to the human eye information acquisition unit 3, the image magnification optical path unit 2 and the image generation unit 1. The data processing unit 4 obtains the viewer's pupil distance information and performs human eye tracking according to the human eye information acquisition unit 3, and obtains the display arrangement mode of the image generation unit 1 in combination with the parameter inverse operation of the image magnification optical path unit 2, so that the viewer's left and right eyes can capture the light of the left and right viewpoints of the 3D image.
[0042] In this embodiment, the 3D image generated by the 4.1-inch naked-eye 3D screen is mainly used, and the image amplification effect of the image amplification optical path unit 2 is used to form a virtual image of more than 50 inches at a distance of about 5 meters from the human eye.
[0043] Since people are constantly moving, this embodiment installs a camera on the window to capture the viewer's position, pupil distance and other information, so as to adjust the position of the virtual image based on the viewer's position information, so that the 50-inch large-format screen corresponding to the virtual image is always 3-5 meters away from the viewer.
[0044] In addition, this embodiment also uses a camera to capture the viewer's pupil distance information, and based on the tilt direction of the viewer's pupil distance relative to the window, the inverse operation preset position of the image generation unit 1 is determined through the inverse operation of the optical path. The data processing unit 4 regulates the display arrangement mode of the image generation unit 1 so that the image generation unit 1 generates a 3D image at the inverse operation preset position, so that the 3D image generated by the image generation unit 1 can be fully seen by the viewer.
[0045] In order to magnify the 3D image generated by the 4.1-inch naked-eye 3D screen, the image magnifying optical path unit 2 includes a convex lens arranged directly in front of the image generating unit 1, and a semi-transparent and semi-reflective mirror arranged obliquely in front of the convex lens, and a concave mirror for reflecting the light path is installed on the side of the semi-transparent and semi-reflective mirror.
[0046] The 3D image generated by the image generation unit 1 passes through the convex lens and is focused at the human eye position after being reflected by the semi-transparent and semi-reflective mirrors and the concave mirror, and the 3D image forms a virtual image at a set distance from the human eye position.
[0047] In this embodiment, a 4.1-inch naked-eye 3D screen is used as a display image source (PDU), and an optical path that can magnify the image is constructed through optical devices such as a convex lens, a semi-transparent and semi-reflective mirror, and a curved reflector.
[0048] In order to enable the left and right eyes of the viewer to accurately capture the light of the left and right viewpoints of the 3D image, the data processing unit 4 adjusts the display arrangement mode of the image generation unit 1 so that the image generation unit 1 generates a 3D image at the preset position of the inverse operation, and the 3D image generated by the image generation unit 1 is completely seen by the viewer. The specific implementation method is as follows:
[0049] The pupil distance information is obtained through the camera to determine the viewing light path of the viewer's pupil line of sight relative to the window. In order to inversely adjust the display arrangement of the display image source, the viewing light path is reflected by the concave mirror, reflected by the semi-transparent and semi-reflective mirror, and transmitted by the convex lens, and then focused on the display image source end to form the inverse operation preset position of the image generation unit 1. The data processing unit 4 regulates the display arrangement of the image generation unit 1, so that the image generation unit 1 generates a 3D image at the inverse operation preset position, so that the left and right eyes of the viewer can accurately capture the light of the left and right viewpoints of the 3D image.
[0050] In order to ensure that the 50-inch large-format picture corresponding to the virtual image is always 3-5 meters away from the viewer, the following methods are implemented:
[0051] The data processing unit 4 is provided with an imaging position setting module, which determines the real-time distance between the viewer's position and the visual window according to the human eye information acquisition unit 3, and calculates the dynamic distance between the virtual image position and the visual window according to the real-time distance and the set distance between the virtual image and the human eye position.
[0052] The data processing unit 4 controls the display arrangement mode of the image generating unit 1, so that the image generating unit 1 generates a 3D image at the preset position of the inverse operation in the following manner:
[0053] The data processing unit 4 is provided with a display arrangement inverse operation module, which first determines the viewing light path of the human eye based on the pupil distance information captured by the human eye information acquisition unit 3, and then calculates the inverse operation preset position of the image generation unit 1 according to the viewing light path of the human eye, the concave mirror, the semi-transparent and semi-reflective mirror and the reverse light path of the convex lens.
[0054] The data processing unit 4 regulates the display arrangement of the image generating unit 1 so that the image generating unit 1 generates a 3D image at the preset position of the inverse operation, so that the 3D image generated by the image generating unit 1 can be fully seen by the viewer.
[0055] In order to calculate the inverse operation preset position of the image generation unit 1, an optical path unit simulation model is provided in the display arrangement inverse operation module. The optical path unit simulation model restores the positions of the concave mirror, the semi-transparent and semi-reflective mirror, and the convex lens one-to-one, and determines the position of the window relative to the optical path unit simulation model, and integrates the window into the optical path unit simulation model.
[0056] A two-dimensional coordinate system is constructed at the position of the visual window, and a light path for viewing by the human eye is determined based on the pupil distance information captured by the human eye information acquisition unit 3, and an incident ray corresponding to the light path for viewing by the human eye in the two-dimensional coordinate system is determined.
[0057] The inverse calculation is based on the human eye viewing light path after the human eye viewing light path passes through the concave mirror, the semi-transparent and semi-reflective mirror and the convex lens, and the data processing unit 4 adjusts the display arrangement mode of the image generating unit 1 according to the difference between the inverse calculation preset position and the actual position of the image generating unit 1, so that the 3D image generated by the image generating unit 1 coincides with the 3D image generated by the image generating unit 1 at the inverse calculation preset position.
[0058] A two-dimensional coordinate system is constructed based on the actual position of the image generating unit 1, so that the two-dimensional coordinate value of the actual position of the image generating unit 1 is (0, 0), and the two-dimensional coordinate value corresponding to the inverse operation preset position calculated by the data processing unit 4 is determined. The data processing unit 4 adjusts the display arrangement mode of the image generating unit 1 based on the difference between the two-dimensional coordinate value of the inverse operation preset position and the two-dimensional coordinate value of the actual position of the image generating unit 1.
[0059] In order to enable the 3D image generated by the image generating unit 1 to allow the viewer's left and right eyes to accurately capture the left and right viewpoints of the 3D image, it is necessary to adjust the display arrangement of the image generating unit 1 according to the viewer's pupil distance information (such as the viewer's line of sight angle), so that the 3D image generated by the image generating unit 1 can enter the viewer along the viewer's current line of sight angle, so that the viewer's left and right eyes can accurately capture the left and right viewpoints of the 3D image. If the left and right viewpoints of the 3D image generated by the image generating unit 1 deviate from the viewer's left and right eyes, the viewer's eyes cannot accurately see the left and right viewpoints of the 3D image.
[0060] The data processing unit 4 adjusts the display arrangement of the image generating unit 1 according to the difference between the preset position of the inverse operation and the actual position of the image generating unit 1, so that the 3D image generated by the image generating unit 1 coincides with the 3D image generated by the image generating unit 1 at the preset position of the inverse operation. The 3D image generated by the image generating unit 1 follows the optical path formed by the convex lens, the semi-transparent mirror and the curved reflector, and enters the left and right eyes of the viewer along the current line of sight of the viewer. Therefore, this embodiment ensures that the human eye can correctly receive the left and right viewpoint images of the 3D image through human eye tracking and adjustment of the optical path parameters.
[0061] In addition, in order to ensure that the enlarged 3D picture generated by the virtual image can maintain a stable distance from the human eye, the real-time distance between the viewer's position and the window, as well as the real-time distance and the set distance between the virtual image and the human eye position are determined according to the human eye information acquisition unit 3, and the dynamic distance between the position of the virtual image and the window is calculated. The data processing system forms the virtual image at the dynamic distance, realizing the large-screen display of the telescopic image on the vehicle-mounted screen, and solving the dizziness problem of watching the screen while the car is driving.
[0062] Based on the above-mentioned vehicle-mounted naked-eye 3D telescopic light field entertainment system, this embodiment further provides a control method for the above-mentioned vehicle-mounted naked-eye 3D telescopic light field entertainment system, including the following steps:
[0063] Step 100: using a camera in the viewing window to determine the eye position information and pupil distance information of the viewer relative to the viewing window;
[0064] Step 200: The data processing system determines the display position of the virtual image based on the eye position information of the viewer relative to the viewing window and the set distance between the position of the virtual image and the eye position;
[0065] Step 300: The data processing system constructs a light path unit simulation model to perform eye tracking. The data processing system calculates the preset position of the light path of the human eye after it passes through the concave mirror, the semi-transparent and semi-reflective mirror, and the convex lens in sequence based on the pupil distance information of the viewer and the light path unit simulation model by inverse calculation.
[0066] Step 400: The data processing system adjusts the display arrangement of the image generating unit based on the difference between the preset position of the inverse operation and the actual position of the image generating unit, so that the 3D image generated by the image generating unit overlaps with the 3D image generated by the image generating unit at the preset position of the inverse operation.
[0067] A difference threshold between the inverse operation preset position and the actual position of the image generation unit is set, and when the difference between the inverse operation preset position and the actual position of the image generation unit exceeds the difference threshold, the display arrangement mode of the image generation unit is adjusted.
[0068] When the difference between the preset position of the inverse operation and the actual position of the image generation unit does not exceed the difference threshold, the display arrangement mode of the image generation unit is not adjusted.
[0069] This implementation combines a convex lens, a concave mirror for magnification, and a special optical path design of a semi-transparent and semi-reflective mirror to achieve a large-screen display of a telescopic image on the vehicle screen, thereby solving the dizziness problem of watching the screen while the car is driving. By tracking the human eye and adjusting the optical path parameters, it is ensured that the human eye can correctly receive the left and right viewpoints of the 3D image.
