[0036] Various exemplary embodiments of this specification will now be described in detail with reference to the accompanying drawings.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the embodiments of this specification or their application or use.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] One embodiment of the present invention provides a virtual reality system. According to... Figure 1 As shown, the virtual reality system includes a camera 110 and a virtual reality glasses box 120. The camera 110 and the virtual reality glasses box 120 can be used together, and the camera 110 can also be used independently.

[0040] according to Figure 2 As shown, the camera includes a first wide-angle camera 111 and a second wide-angle camera 112.

[0041] according to Figure 3 As shown, the camera also includes a first display screen 113 and a second display screen 114.

[0042] The virtual reality headset includes a binocular optical component. This component comprises two sets of optical lenses. These lenses simulate the human eye's perception of objects, giving the user a three-dimensional view.

[0043] The camera stores a first video and a second video. The first video was captured by the first wide-angle camera, and the second video was captured by the second wide-angle camera.

[0044] In this embodiment, when the camera is placed in the virtual reality glasses box and a target video is selected from the captured videos, the first display screen is used to play the first video in the target video, and the second display screen is used to play the second video in the target video, so that the user can view the images played on the first display screen and the second display screen through binocular optical components.

[0045] The selection of a target video from various captured videos can be achieved in any of the following ways. For example, the camera may have a video selection button, allowing the user to trigger the button to select the target video. Alternatively, the virtual reality system may include a controller. The controller and camera are connected, allowing the user to operate the controller to select the target video. The connection between the controller and camera can be a Wi-Fi connection or a Bluetooth connection.

[0046] The virtual reality system provided in this embodiment, through the combined use of a camera and a virtual reality glasses box, makes the images seen by the user and captured by the camera have a sense of three-dimensionality and immersion.

[0047] In some embodiments, when the camera is not placed in the virtual reality headset box and a target video is selected from the captured videos, the target video is played on one of the first and second displays, while a touch interface is displayed on the other display. For example, the first display plays a first video from the target video, and the second display shows the touch interface. As another example, the first display shows the touch interface, and the second display plays a second video from the target video.

[0048] The touch interface displays shooting and video playback controls. The shooting controls include controls for managing the shooting process and controls for adjusting shooting parameters. Controls for managing the shooting process include a start shooting button and a finish shooting button. Controls for adjusting shooting parameters include a focus button, a flash-on button, and a beauty mode button.

[0049] In this embodiment, the camera can be used independently of the virtual reality glasses box, increasing the functionality of the virtual reality system.

[0050] Figure 4 A flowchart of a video playback method according to an embodiment of the present disclosure is shown. This method is applied to a virtual reality system provided in any of the above embodiments. Figure 1 As shown, the method includes steps S410 to S420.

[0051] Step S410: In response to the user triggering the playback of the target video, determine whether the camera is placed in the virtual reality glasses box.

[0052] In step S420, with the camera placed in the virtual reality glasses box, the first display screen is controlled to play the first video in the target video, and the second display screen is controlled to play the second video in the target video, so that the user can view the images displayed on the first display screen and the second display screen through binocular optical components.

[0053] In this embodiment, the playback mode of the camera is determined based on whether the camera is placed in the virtual reality glasses box, realizing automatic switching of the camera playback mode without manual operation. On the other hand, through the combined use of the camera and the virtual reality glasses box, the images seen by the user and captured by the camera have a sense of three-dimensionality and immersion.

[0054] In some embodiments, the method further includes: controlling one of the first and second displays to play a target video when the camera is not placed in the virtual reality glasses box, and the other display to show a touch interface.

[0055] In some embodiments, the camera includes a photosensor. Determining whether the camera is placed within the virtual reality headset specifically includes: acquiring a light intensity value collected by the photosensor; if the light intensity value is less than a preset intensity value, determining that the camera is placed within the virtual reality headset; if the light intensity value is greater than or equal to the preset intensity value, determining that the camera is not placed within the virtual reality headset.

[0056] There are other ways to determine whether the camera is placed in the virtual reality headset box, such as by using a distance sensor or a pressure sensor set in the camera.

[0057] In some embodiments, the camera further includes a pose information acquisition component. The pose information acquisition component is used to acquire the camera's pose data. The camera's pose data can reflect the dynamic changes of the camera in real space. The pose information component includes an inertial sensor and a positioning camera. Figure 2 As shown, the camera also includes two positioning cameras 115.

[0058] In this embodiment, the method further includes: when the camera is shooting video, determining the camera's pose data based on the data collected by the pose information acquisition component; establishing a correspondence between the camera's pose data and each frame of the video being shot; determining the pose data of the virtual camera based on the pose data corresponding to each frame; and generating virtual elements in the corresponding images using the pose data of the virtual camera.

[0059] The acquired camera pose data is correlated with each frame captured during video recording, meaning each frame corresponds to a single camera pose data point. Based on the pose data for each frame, the virtual camera's pose data in virtual space is determined to ensure its motion in the virtual world mirrors its motion in the real world. Using the virtual camera's pose data, virtual elements are synthesized or added to the corresponding image frames. These virtual elements can be 3D models, animations, or text. In this embodiment, precise pose matching allows the virtual elements generated in the corresponding images to blend more naturally into the real-world video footage, enhancing the user's viewing experience. This approach can be applied to various fields such as film production, game development, and advertising.

[0060] This embodiment provides a camera for implementing any of the above method embodiments. Figure 5 A structural block diagram of a camera according to an embodiment of the present disclosure is shown. Figure 5 As shown, the camera 500 includes a position determination module 510 and a control module 520.

[0061] The position determination module 510 is used to determine whether the camera is placed in the virtual reality glasses box in response to the user triggering video playback.

[0062] The control module 520 is used to control the first display screen to play the first video in the target video and the second display screen to play the second video in the target video when the camera is placed in the virtual reality glasses box, so that the user can view the images displayed on the first display screen and the second display screen through binocular optical components.

[0063] In some embodiments, the control module 520 is also configured to control one of the first and second displays to play the target video and the other display to show the touch interface when the camera is not placed in the virtual reality glasses box.

[0064] In some embodiments, the camera includes a photosensor. The position determination module 510 is used to acquire the light intensity value collected by the photosensor; if the light intensity value is less than a preset intensity value, it is determined that the camera is placed in the virtual reality glasses box. If the light intensity value is greater than or equal to the preset intensity value, it is determined that the camera is not placed in the virtual reality glasses box.

[0065] In some embodiments, the camera further includes a pose information acquisition component, which is used to acquire the pose data of the camera. The camera also includes a virtual element generation module. The virtual element generation module is used to, when the camera is recording video, determine the camera's pose data based on the data acquired by the pose information acquisition component; establish a correspondence between the camera's pose data and each frame of the video being recorded; determine the pose data of a virtual camera based on the pose data corresponding to each frame; and generate virtual elements in the corresponding images using the virtual camera's pose data.

[0066] This disclosure also provides a camera for implementing any of the above method embodiments.
