[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] See below Figure 1 , Figure 1 A flowchart of an image display method provided in an embodiment of the present application.

[0039] Specific steps may include:

[0040] S101: Acquire eyeball rotation information, and determine the actual coordinates of the eye gaze point in the world coordinate system according to the eyeball rotation information;

[0041] Among them, this embodiment can be applied to wearable devices such as AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, VR helmets, etc. that provide image display functions through display devices. The above-mentioned display device can be a pair of glasses lenses or a display screen.

[0042] The eyeball rotation information mentioned in this step is information describing the direction and angle of eyeball rotation, and the eyeball rotation information may include the rotation information of one or two eyeballs, and the eyeball gaze point may be determined based on the eyeball rotation information. As a feasible implementation, this embodiment may use an eyeball tracking device to obtain the eyeball rotation information; wherein the eyeball rotation information includes the angle of the eyeball rotation within a preset period and the direction of the eyeball rotation.

[0043] See also Figure 2 , Figure 2A schematic diagram of the principle of determining the eye gaze point provided in an embodiment of the present application, this embodiment can calculate the eye gaze point based on the line of sight direction of both eyes and the distance between both eyes combined with triangular geometric features. The process of determining the eye gaze point in this implementation can be converted into a side and two angles of a known triangle, and the position of the third vertex is calculated. This embodiment can calculate the line of sight direction of both eyes based on eye rotation information. The world coordinate system is a coordinate system in the real space where the user is located, and can be a Cartesian coordinate system established with a certain part of the user's body (such as the tip of the nose or the top of the head) as the origin.

[0044] S102: Determine the virtual coordinates of the eye gaze point in the virtual camera coordinate system according to the real coordinates;

[0045] Among them, the wearable device used in this embodiment can run a three-dimensional engine, which refers to a core component that can realize an interactive real-time image application. Through the three-dimensional engine, a three-dimensional model can be created in a virtual space, and the three-dimensional model in the virtual space can be photographed by a virtual camera to obtain the image that the user needs to observe, so that the user can experience an immersive and realistic feeling through the virtual camera shooting picture in the virtual space. Common three-dimensional engines may include Unity3D, Unreal Engine, Frost Engine, etc. Unity3D is a multi-platform comprehensive game engine that can create interactive content such as three-dimensional video games, architectural visualization, real-time three-dimensional animation, etc. Unity is similar to Director, Blendergame engine, Virtools or Torque Game Builder, etc., which use interactive graphical development environments as the primary method. The image display in the virtual space created by Unity3D is based on the principles of computer graphics. The size of the display screen is limited according to the clipping window, and the nearest and farthest distances of the scenery that the user can see are determined by determining the near clipping plane and the far clipping plane. Without changing the shooting angle of the virtual camera, what the user wants to see and the focus of attention are obtained by the user by adjusting the eyes to change to the focal plane and focus.

[0046] In this step, the virtual camera coordinate system is the coordinate system of the virtual space where the virtual camera is located. In this embodiment, the position of the eye focus point in the virtual space, that is, the virtual coordinates, can be determined according to the conversion relationship between the virtual camera coordinate system and the world coordinate system. Specifically, in this embodiment, the coordinates can be converted to the coordinate system according to the conversion relationship between the world coordinate system and the virtual camera coordinate system to obtain the virtual coordinates of the eye focus point in the virtual camera coordinate system. Specifically, if the ratio of the virtual space to the real world is equal, the real coordinates can be directly used as the virtual coordinates. If there is a scaling ratio between the virtual space and the real world, the real coordinates can be proportionally changed to obtain the virtual coordinates.

[0047] S103: adjusting the shooting angle of the virtual camera according to the virtual coordinates, and displaying the picture shot by the virtual camera after the shooting angle is adjusted as the target image.

[0048] Among them, this step is based on the virtual coordinates that have been determined, and the shooting angle of the virtual camera can be adjusted according to the virtual coordinates so that the focus of the virtual camera falls on the virtual coordinates. After the shooting angle of the virtual camera is adjusted, the picture taken by the virtual camera can be displayed as the target image. Since the target image is the picture taken by the virtual camera after adjusting the shooting angle, the target image is imaged on the focal plane of the user's eyes, and the user does not need to adjust the focal length by the tension of the eye muscles.

[0049] It is understandable that when a person's eyes look in different directions, there will be slight changes in the eyes. This embodiment obtains the eye gaze position based on the eye rotation information, thereby tracking the changes in the eyes in real time, predicting the user's state and needs, and responding by controlling the shooting angle of the virtual camera to achieve the purpose of controlling the device with the eyes. As a feasible implementation method, this embodiment can also use eye tracking technology to determine the eye gaze point, and calculate the position of the human eye in the AR image or VR image, adjust the shooting angle of the virtual camera to simulate the convergence of the human eye, and display the shooting picture after adjusting the shooting angle as the target image to achieve the simulation of human eye convergence in the three-dimensional engine. Convergence refers to the convergence of the binocular visual axis. When the user looks at an object, the binocular convergence makes the object fall on the corresponding position of the retina. When the position of the object changes in distance, the size of the convergence angle also changes accordingly, and this change is completed by the eye muscles. The signal of this change is transmitted to the brain, which constitutes a perception of depth information.

[0050] This embodiment determines the real coordinates of the eye gaze point in the world coordinate system based on the eyeball rotation information, and determines the virtual coordinates of the eye gaze point in the virtual camera coordinate system. The image observed by the eye is the image taken by the virtual camera in the virtual space. Therefore, by adjusting the shooting angle of the virtual camera according to the virtual coordinates, the image taken by the virtual camera can be imaged on the focal plane of the eye. The glasses do not need to adjust the focal length, avoiding visual fatigue caused by changes in the tension of the muscles around the eyes. The virtual camera shooting angle adjustment method in this embodiment can truly simulate the eye movement state, generate images that are adapted to convergence, and avoid visual fatigue caused by frequent zooming of the eyes.

[0051] As for Figure 1 For further description of the corresponding embodiment, the user usually uses both eyes to observe the image displayed by the wearable device, such as Figure 2The eyeball rotation information may include left eye rotation information and right eye rotation information, and then the left eye viewing angle is determined according to the left eye rotation information, the right eye viewing angle is determined according to the right eye rotation information, and the real coordinates of the eye gaze point in the world coordinate system are determined according to the left eye viewing angle, the right eye viewing angle and the pupil distance. Accordingly, in order to better conform to human observation habits, Figure 1 The virtual camera mentioned in the corresponding embodiment may include a first virtual camera and a second virtual camera, wherein the first virtual camera is used to capture the target image observed by the left eye; and the second virtual camera is used to capture the target image observed by the right eye.

[0052] See also Figure 3 , Figure 3 A schematic diagram of a method for determining a shooting angle characteristic of a virtual camera provided in an embodiment of the present application is shown in FIG. Figure 3 The dotted line in is the shooting direction of the virtual camera before adjusting the shooting angle, and the solid line is the shooting direction of the virtual camera after adjusting the shooting angle. In the process of adjusting the shooting angle of the virtual camera according to the virtual coordinates, the camera coordinates of the virtual camera in the virtual space can be determined first, and the shooting angle of the virtual camera can be adjusted according to the positional relationship between the camera coordinates and the virtual coordinates. Among them, the shooting direction of the virtual camera after adjusting the shooting direction is the same as the preset direction, and the preset direction is the direction in which the camera coordinates point to the virtual coordinates. It can be understood that when there are a first virtual camera and a second virtual camera corresponding to both eyes in the virtual space, respectively, the shooting angle of the first virtual camera can be adjusted according to the positional relationship between the camera coordinates of the first virtual camera and the virtual coordinates, and the shooting angle of the second virtual camera can be adjusted according to the positional relationship between the camera coordinates of the second virtual camera and the virtual coordinates.

[0053] As a feasible implementation, the specific process of adjusting the shooting angle of the virtual camera may be: determining the original shooting angle of the virtual camera before the shooting angle is adjusted, determining the target shooting angle of the virtual camera according to the virtual coordinates, and controlling the virtual camera to rotate from the original shooting angle to the target shooting angle. The target shooting angle is determined according to the virtual coordinates and the coordinates of the virtual camera.

[0054] The process described in the above embodiment is explained below through an embodiment in actual application. This embodiment describes a VR glasses display solution that simulates human eye convergence in a virtual space created by Unity3D, which may specifically include the following steps:

[0055] Step 1: Use an eye-tracking device to track the movement of the eyeballs and obtain the rotation angle φ1 of the eyeballs of both eyes;

[0056] The rotation angle can be determined by the degree of change in the angle between the current sight line direction of the eyeball and the preset direction, where the preset direction is the sight line direction when the human eye looks vertically at the VR screen.

[0057] Step 2: Calculate the gaze point of both eyes through the triangle geometric features and the rotation angle φ1, and calculate the real coordinates D(x1, y1, z1) of the gaze point in the world coordinate system, and upload the real coordinates D(x1, y1, z1) to the unity3D program;

[0058] Step 3: The Unity3D program converts the real coordinates D(x1, y1, z1) of the gaze point into the virtual coordinates d(x2, y2, z2) of the Unity3D virtual space, and then adjusts the rotation angle of the two virtual cameras in the Unity3D virtual space to φ2 according to the geometric characteristics of the triangle. The rotation angle of the two virtual cameras simulates the rotation φ2 of the human eye to realize the human eye convergence phenomenon.

[0059] The virtual coordinates are coordinates on a virtual space coordinate system, and the virtual space coordinate system may be a Cartesian coordinate system with a virtual camera in Unity3D as the coordinate origin o(0,0,0).

[0060] Step 4: VR glasses display the images captured by the virtual camera in the Unity3D virtual space. The images fall exactly on the focal plane where the user's eyes are focused. The user can clearly see the images in the Unity3D virtual space without having to readjust the eye muscles to change the focus.

[0061] In this embodiment, the rotation angle of the virtual camera is adjusted by the eyeball rotation information, the virtual camera simulates the direction of the human eye's gaze, and then the displayed picture is controlled by the direction of the virtual camera. In this embodiment, the eye's gaze point is calculated by the rotation angle of both eyes, and then the gaze point is converted into the rotation angle of the virtual camera and the picture taken after the rotation of the virtual camera is displayed. In this embodiment, the angle of the virtual camera is adjusted according to the rotation of the human eye, so that the displayed picture is always displayed in the focal plane, which can avoid visual fatigue caused by frequent zooming of the eyes.

The image observed by the eye is the image taken by the virtual camera in the virtual space. Therefore, by adjusting the shooting angle of the virtual camera according to the virtual coordinates, the image taken by the virtual camera can be imaged on the focal plane of the eye. The glasses do not need to adjust the focal length, avoiding visual fatigue caused by changes in the tension of the muscles around the eyes.
