Fig. 1 shows a flowchart of an image display method 100 provided in an embodiment of the present disclosure. The subject of execution of method 100 may be an augmented reality device, which may include, but is not limited to, the following types:

And the computer-side virtual reality (PCVR) equipment performs related calculation of virtual reality functions and data output by using the PC side, and the external computer-side virtual reality equipment realizes the effect of virtual reality by using the data output by the PC side.

The mobile virtual reality device supports setting up a mobile terminal (such as a smart phone) in various manners (such as a head-mounted display provided with a special card slot), performing related calculation of a virtual reality function by the mobile terminal through connection with the mobile terminal in a wired or wireless manner, and outputting data to the mobile virtual reality device, for example, watching a virtual reality video through an APP of the mobile terminal.

The integrated virtual reality device has a processor for performing the calculation related to the virtual function, and thus has independent virtual reality input and output functions, and is free from connection with a PC or a mobile terminal, and has high degree of freedom in use.

Of course, the form of implementation of the augmented reality device is not limited to this, and may be further miniaturized or enlarged as needed.

The sensor (such as a nine-axis sensor) for detecting the gesture in the augmented reality device is arranged in the augmented reality device, and is used for detecting the gesture change of the augmented reality device in real time, if the user wears the augmented reality device, when the gesture of the head of the user changes, the real-time gesture of the head is transmitted to the processor, so that the gaze point of the sight of the user in the virtual environment is calculated, an image in the gaze range (namely a virtual field of view) of the user in the three-dimensional model of the virtual environment is calculated according to the gaze point, and the image is displayed on the display screen, so that the user looks like watching in the real environment.

An augmented reality device, such as an HMD, incorporates several cameras (e.g., depth cameras, RGB cameras, etc.), the purpose of which is not limited to providing a through view only. The camera images and integrated Inertial Measurement Unit (IMU) provide data that can be processed by computer vision methods to automatically analyze and understand the environment. Also, HMDs are designed to support not only passive computer vision analysis, but also active computer vision analysis. The passive computer vision method analyzes image information captured from the environment. These methods may be monoscopic (images from a single camera) or stereoscopic (images from two cameras). Including but not limited to feature tracking, object recognition, and depth estimation. Active computer vision methods add information to the environment by projecting a pattern that is visible to the camera but not necessarily to the human vision system. Such techniques include time-of-flight (ToF) cameras, laser scanning, or structured light to simplify stereo matching issues. Active computer vision is used to implement scene depth reconstruction.

Referring to fig. 1, the image display method 100 includes steps S120 to S160:

Step S120: displaying a first virtual reality space image presented based on a first virtual camera, and sending the first virtual reality space image to a video recording device communicatively connected to the augmented reality device, so that the video recording device displays the first virtual reality space image;

Step S140: in response to a user's view angle switching operation, displaying a second virtual reality space image presented based on a second virtual camera; the first virtual reality space image and the second virtual reality space image are used for showing different display viewing angles of the same virtual reality space;

Step S160: and sending the second virtual reality space image to the video recording device so that the video recording device displays the second virtual reality space image.

The virtual reality space may be a simulation environment for the real world, a virtual scene of half simulation and half virtual, or a virtual scene of pure virtual. The virtual scene may be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene or a three-dimensional virtual scene, and the dimension of the virtual scene is not limited in the embodiment of the present application. For example, a virtual scene may include sky, land, sea, etc., the land may include environmental elements of a desert, city, etc., and a user may control a virtual object to move in the virtual scene.

Referring to fig. 2, a user may enter a virtual reality space through an augmented reality device such as head-mounted VR glasses, and control his/her Avatar (Avatar) in the virtual reality space to perform social interactions, entertainment, learning, remote office, etc. with other user-controlled avatars. In some embodiments, the avatar may display an animated avatar of the avatar or a real image of the user, which the present disclosure is not limited to.

In one embodiment, in virtual reality space, a user may implement related interactive operations through a controller, which may be a handle, for example, a user performs related operation control through operation of keys of the handle. Of course, in other embodiments, the target object in the augmented reality device may be controlled using gesture or voice or multi-modal control without using a controller.

In some embodiments, more than two virtual cameras with different shooting angles are arranged in the virtual reality space displayed by the augmented reality device. Wherein, the virtual camera is a tool used for simulating the visual angle and the visual field seen by a user in the virtual reality environment, and can be used for presenting a two-dimensional image of a three-dimensional scene in the virtual reality space.

Fig. 3 shows an alternative schematic view of a virtual field of view of an augmented reality device according to an embodiment of the disclosure, where a horizontal field of view angle and a vertical field of view angle are used to describe a distribution range of the virtual field of view in a virtual environment, a vertical direction of distribution range is represented by a vertical field of view angle BOC, a horizontal direction of distribution range is represented by a horizontal field of view angle AOB, and an image of the virtual field of view in the virtual environment can always be perceived by a human eye through a lens. The angle of view represents a distribution range of viewing angles that the lens has when sensing an environment. For example, the angle of view of an augmented reality device represents the range of distribution of viewing angles that the human eye has when a virtual environment is perceived through a lens of the augmented reality device; for another example, in a mobile terminal provided with a camera, the field angle of the camera is a distribution range of the viewing angle that the camera has when sensing the real environment to shoot.

Illustratively, referring to fig. 4, virtual cameras 11, 12, 13, and 14 of 4 different photographing angles are provided in the virtual reality space 10 for presenting virtual reality space 10 of different angles, and an avatar of a user at different angles, respectively. Wherein the virtual camera 11 may be used for presenting a first virtual reality space image of a first perspective of said virtual reality space 10, the virtual camera 12 may be used for presenting a second virtual reality space image of a second perspective of said virtual reality space 10, the virtual camera 13 may be used for presenting a third virtual reality space image of a third perspective of said virtual reality space 10, and the virtual camera 14 may be used for presenting a fourth virtual reality space image of a fourth perspective of said virtual reality space 10.

At this time, the user can switch the augmented reality device from the currently displayed first virtual reality space image based on the first virtual camera 11 to the second virtual reality space image based on the second virtual camera 12 through a preset viewing angle switching operation, and transmit the image data of the second virtual reality space image to the video recording device. Referring to fig. 5-6, the display content of the video recording device is switched from the first virtual reality space image 21 to the second virtual reality space image 22 accordingly.

In some embodiments, the viewing angle switching operation includes, but is not limited to, a somatosensory control operation, a gesture control operation, an eye shake operation, a touch control operation, a voice control instruction, or an operation to an external control device.

In some embodiments, the video recording end may record the virtual reality space image sent by the augmented reality device while displaying the virtual reality space image, so as to facilitate subsequent processing, such as storage, uploading, clipping, and the like.

Thus, according to the image display method provided by one or more embodiments of the present disclosure, by displaying the first virtual reality space image presented based on the first virtual camera, transmitting the first virtual reality space image to the video recording device, so that the video recording device displays the first virtual reality space image, displaying the second virtual reality space image presented based on the second virtual camera in response to the user's viewing angle switching operation, and transmitting the second virtual reality space image to the video recording device, so that the video recording device displays the second virtual reality space image, it is possible to correspondingly switch the display viewing angle of the virtual reality space image presented by the video recording device while switching the display viewing angle of the virtual reality space in the augmented reality device, thereby improving the picture richness of the mixed reality recording (MRC) and facilitating the user to perform subsequent processing (e.g., video clipping, etc.).

In some embodiments, the communication connection between the extended display device and the video recording device includes, but is not limited to, radio Frequency (RF) communication, zigbee communication protocols, wiFi, infrared, wireless Universal Serial Bus (USB), ultra Wideband (UWB), bluetooth communication protocols, and cellular communication, such as code division multiple access (CDM) or global system for mobile communications (GSM).

In some embodiments, step S140 includes:

Step A1: in response to a first operation of a user, displaying at least one preview image based on virtual reality space images presented by other virtual cameras than the first virtual camera;

step A2: in response to a second operation by the user for the displayed at least one preview image, a second virtual reality space image based on the second virtual camera presentation is displayed.

The first and second operations include, but are not limited to, a somatosensory control operation, a gesture control operation, an eyeball shaking operation, a touch control operation, a voice control instruction, or an operation of an external control device.

7A-7B, the augmented reality device may display a preview image (or thumbnail image) 31 of a virtual reality space image currently in use based on the first virtual camera presentation and preview images (or thumbnail images) 32, 33, and 34 of virtual reality space images presented based on the second, third, and fourth virtual cameras, respectively, within the virtual reality space in response to a first operation by the user (e.g., triggering a preset key on the VR handle). The user may select the preview image 32 by controlling the handle rays to cause the display content of the augmented reality device to switch to a second virtual reality space image presented based on the second virtual camera.

In some embodiments, the method 100 further comprises:

step S170: receiving a switching instruction sent by the video recording equipment;

step S180: responding to the switching instruction, and acquiring other virtual reality space images presented by other virtual cameras except the virtual camera currently in use;

Step S190: and sending the other virtual reality space images to the video recording device so that the video recording device displays the other virtual reality space images.

In this embodiment, by enabling the augmented reality device to receive the switching instruction sent by the video recording device, and in response to the switching instruction, obtain other virtual reality space images presented by other virtual cameras except for the virtual camera currently being used, and send the other virtual reality space images to the video recording device, a user (for example, a video recorder) can obtain virtual reality space images with different viewing angles at the video recording end in real time as required, so as to facilitate subsequent processing (for example, video clipping) and the like.

In some embodiments, when the augmented reality device acquires other virtual reality space images in response to the switching instruction, the augmented reality device may still remain displayed based on the virtual reality space images presented by the virtual camera currently being used, without displaying the other virtual reality space images acquired, i.e., the augmented reality device sends only the other virtual reality space images acquired to the video recording end to meet the needs of the video recorder, without switching the other virtual reality space images acquired to be displayed within the augmented reality device so as not to interfere with the autonomous use experience of the user of the augmented reality device.

For example, assuming that the current augmented reality device currently displays a first virtual reality space image based on the presentation of the first virtual camera, if a user of the video recording device wants the video recording device to be able to present a second virtual reality space image, the user may operate the video recording device to send a switching instruction to the augmented reality device to switch to the second virtual reality space image, so that the augmented reality device transmits the second virtual reality space image back to the video recording device for the video recording device to display, but the augmented reality device still continues to display the first virtual reality space image based on the presentation of the first virtual camera.

Accordingly, fig. 8 illustrates that an image display method 200 is provided according to an embodiment of the present disclosure, which is applied to a video recording apparatus. The video recording end may be an intelligent mobile terminal, for example, including but not limited to a mobile phone, a notebook computer, a PAD (tablet personal computer), and the like.

Referring to fig. 8, the image display method 200 includes steps S220 to S260:

step S220: receiving a first virtual reality space image based on the presentation of a first virtual camera sent from an augmented reality device, and displaying the first virtual reality space image;

Step S240: responding to preset operation of a user, sending a switching instruction to the augmented reality device, so that the augmented reality device responds to the switching instruction to acquire other virtual reality space images presented by other virtual cameras except the virtual camera currently in use and transmit the other virtual reality space images back;

step S260: and receiving the other virtual reality space images sent by the augmented reality device and displaying the other virtual reality space images.

The preset operation includes, but is not limited to, a somatosensory control operation, a gesture control operation, an eyeball shaking operation, a touch control operation, a voice control instruction, or an operation of an external control device.

In a specific embodiment, the video recording device may display a preset switching identifier, and each time the switching identifier is triggered by a user, the augmented reality device may be caused to send, to the video recording device, a virtual reality space image presented by a next virtual camera other than the virtual camera currently being used.

In some embodiments, the augmented reality device further transmits target configuration information of the virtual camera set by the augmented reality device in the virtual reality space to the video recording device, so that the video recording device can generate a corresponding switching instruction according to the target configuration information and the operation of the user.

In some embodiments, step S240 includes:

step B1: displaying a target identifier corresponding to a virtual camera set by the augmented reality device in a virtual reality space based on the target configuration information;

Step B2: and responding to the operation of the user for the target identification, and sending a switching instruction for switching to the other virtual cameras to the augmented reality equipment.

Illustratively, the target configuration information may include, but is not limited to, the number of virtual cameras set by the augmented reality device in the virtual reality space, identification information (e.g., camera ID) of each virtual camera, shooting angle of view information corresponding to each virtual camera, and the like. The shooting view angle information may include a near view, a middle view, a far view, a close-up view, or a view of a first person, a third person, or the like.

For example, if the first virtual camera, the second virtual camera, the third virtual camera and the fourth virtual camera are set in the virtual reality space by the augmented reality device, the augmented reality device may send target configuration information corresponding to the first, second, third and fourth virtual cameras to the video recording device, and accordingly, the video recording device may display, based on the received target configuration information, target identifiers corresponding to the first, second, third and fourth virtual cameras for the user to select, and after the user selects the corresponding target identifier, the switching instruction sent by the video recording device to the augmented reality device may include target configuration information of the virtual camera corresponding to the target identifier selected by the user, so that the augmented reality device obtains a virtual reality space image presented by the corresponding virtual camera based on the target configuration information.

Referring to fig. 9, the video recording apparatus may sequentially display 4 target identifications of "lens one", "lens two", "lens three", "lens four" on a screen based on target configuration information of the virtual camera transmitted by the augmented reality apparatus, which sequentially correspond to the first virtual camera, the second virtual camera, the third virtual camera, and the fourth virtual camera set by the augmented reality apparatus. When the user triggers the "shot two" identification, then the video recording device may acquire a second virtual reality space image based on the presentation of the second virtual camera from the augmented reality device, and so on.

Thus, according to one or more embodiments of the present disclosure, by making the augmented reality device further send the target configuration information of the virtual camera to the video recording device, the video recording device displays, based on the target configuration information, the target identifier corresponding to the virtual camera set by the augmented reality device in the virtual reality space for the user to select, so that the user at the video recording end can conveniently switch the lenses with different viewing angles as required in the video recording process, and the richness of virtual reality space image display is improved.
