Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 shows a flowchart of an image display method according to an embodiment of the present disclosure. As shown in fig. 1, the image display method includes the following steps.
S110, determining a first scene area and a second scene area in the virtual scene to be displayed, wherein the attention of a user to the first scene area is larger than the attention of the user to the second scene area.
In this embodiment, when a user wears VR device to perform virtual scene experience, because the user has different attention degrees to different areas in the virtual scene, it is necessary to determine, before displaying the virtual scene or during displaying the scene, scene areas corresponding to the different attention degrees from the virtual scene.
In one case, the first scene area and the second scene area may be determined at the stage of capturing the virtual scene image.
In another case, the first scene area and the second scene area are determined after the virtual scene image is captured and during a rendering phase of the virtual scene image.
The virtual scene to be displayed refers to a virtual scene experienced by a user by wearing the VR device. Alternatively, the type of virtual scene may be a game type, a cartoon type, a space type, or a submarine world type, etc.
The first scene area is an area with higher user attention, and high resolution rendering is needed for the first scene area, so that a user can clearly see the virtual scene displayed in the first scene area.
The second scene area is an area with low attention of the user, so that the second scene area needs to be rendered in a low resolution mode, the user does not need to pay attention to the second scene area, and larger resource consumption of VR equipment is avoided.
In some embodiments, the first scene region is a center region of the virtual scene and the second scene region is an edge region of the virtual scene.
In other embodiments, the first scene region is a foreground region of the virtual scene and the second scene region is a background region of the virtual scene.
In still other embodiments, the first scene region is a region in which moving objects in the virtual scene are located, and the second scene region is a region in which stationary objects in the virtual scene are located.
In still other embodiments, the first scene region is a region within the field of view of the user's eyes or the user's gaze range, and the second scene region is a region outside the field of view of the user's eyes or the user's gaze is absent.
It should be noted that when determining the first scene area and the second scene area, the virtual objects at the boundary positions are considered to perform scene area division, and the same virtual object is not divided into two different scene areas, so that the problem that the same virtual object is rendered by two different resolutions is avoided, and the reliability of scene rendering is ensured.
S120, acquiring a first scene image generated by rendering a first scene area with a first resolution, and acquiring a second scene image generated by rendering a second scene area with a second resolution, wherein the first resolution is greater than the second resolution, and the difference between the first resolution and the second resolution is greater than a preset threshold.
In this embodiment, before the VR device displays the virtual scene, if in the stage of shooting the virtual scene, virtual cameras with different resolutions may be used to shoot different scene areas, so as to obtain images with different resolutions corresponding to the different scene areas; if the virtual scene is shot and then the different scene areas are rendered by adopting different resolutions, the resolution of the image corresponding to the shot virtual scene is the initial resolution, and then the different scene areas are rendered by adopting different resolutions, so that the images with different resolutions corresponding to the different scene areas are obtained.
It can be appreciated that, since the difference between the first resolution and the second resolution is greater than the preset threshold, the resolution of the first scene image and the resolution of the second scene image are obviously compared, so that the second scene image is prevented from interfering with the attention of the user to the first scene image.
The preset threshold may be a resolution determined empirically in advance, and the preset threshold may enable the user to clearly see the first scene image while controlling the resource consumption to be sufficiently small.
Alternatively, the first resolution may be 4K or 8K, and the second resolution may be 1K or 2K.
Therefore, for two different scene areas, two different resolutions are adopted to respectively render, so that scene images with two different resolutions are obtained, the problem of resource consumption when the whole scene area is rendered due to the adoption of uniform high resolution is avoided, and meanwhile, the problem that a user cannot see clearly when the whole scene area is rendered due to the adoption of uniform low resolution is avoided.
S130, generating and displaying a target scene image based on the first scene image and the second scene image.
In this embodiment, the two images may be stitched based on the positions of the pixels in the first scene image and the second scene image, the first scene area, and the second scene area, and the stitched image may be used as the target scene image, and then the target scene image may be displayed on the VR device.
Wherein the target scene image refers to an image to be displayed on a display screen of the VR device.
In this embodiment, optionally, S130 specifically includes: matching the position coordinates of each pixel point in the first scene image with the first scene area to obtain a first target pixel point set successfully matched; matching the position coordinates of each pixel point in the second scene image with the second scene area to obtain a second target pixel point set successfully matched; and synthesizing the first target pixel point set and the second target pixel point set to generate a target scene image for display.
Specifically, by matching each scene image with its corresponding scene area, the position of the pixel point in each scene image in its corresponding scene area can be determined, and the target pixel point set to be spliced is determined, and further based on the position of the pixel point in each scene image in its corresponding scene area, the target pixel point sets corresponding to the two scene images respectively are spliced, so as to obtain a target scene image and display the target scene image.
In this embodiment, the target scene images may be displayed on two display devices, which may be display screens at left and right eyes on the VR device, so that the user can see the target scene images with two different resolutions through two eyes, thereby ensuring that the user can clearly view the interested scene images, and avoiding the VR device from generating larger resource consumption. It should be noted that, whether two scene images with different resolutions are obtained at the stage of shooting a virtual scene or two scene images with different resolutions are rendered after the virtual scene is shot, the first scene image and the second scene image are scene images generated at the same time, that is, the first scene image and the second scene image belong to the same image frame, and then are synthesized into a target scene image corresponding to the whole virtual scene. Thus, the user can conveniently watch the same image frame (namely the target scene image) to perform immersive experience in the virtual scene, and the immersive experience effect of the user is ensured.
The embodiment of the disclosure provides an image display method, which comprises the following steps: determining a first scene area and a second scene area in a virtual scene to be displayed, wherein the attention of a user to the first scene area is greater than the attention of the user to the second scene area; acquiring a first scene image generated by rendering a first scene area with a first resolution, and acquiring a second scene image generated by rendering a second scene area with a second resolution, wherein the first resolution is greater than the second resolution, and the difference between the first resolution and the second resolution is greater than a preset threshold; a target scene image is generated and displayed based on the first scene image and the second scene image. Therefore, the first scene image with high resolution is displayed in the first scene area with higher attention, the second scene image with low resolution is displayed in the second scene area with lower attention, and the user can clearly watch the scene image of interest to improve the immersive experience effect while avoiding the VR equipment from generating larger resource consumption.
In another embodiment of the present disclosure, the first scene area and the second scene area may be determined in different manners in different virtual scenes, and further a scene image corresponding to each scene area is determined.
In some embodiments of the present disclosure, S110 may specifically include the following steps:
a first scene area is determined from the virtual scene according to the eye view range of the user, and an area other than the first scene area is taken as a second scene area.
Wherein the eye field of view is used to characterize the gaze range of the user. The eye field of view range may be determined from the angle of view of the user and the center point of the eyeball. Specifically, an area in the virtual scene within the eye view is taken as a first scene area, and the remaining area of the virtual scene is taken as a second scene area.
It will be appreciated that when determining the eye field of view based on the user's field of view and the center point of the eye, if the same virtual object falls within and outside the eye field of view simultaneously, the eye field of view can be fine-tuned based on the virtual object such that the virtual object falls only within or outside the eye field of view, avoiding the subsequent problem of rendering the same virtual object with two different resolutions.
Therefore, according to the real eye view range of the user, the first scene area positioned in the eye view range and the second scene area positioned outside the eye view range are determined, and compared with the mode of determining the scene areas based on the uniform view range, the reliability of the two scene areas is ensured.
Further, in some embodiments, S120 may specifically include the following steps:
And rendering the virtual scene corresponding to the first scene area by adopting the first resolution to obtain a first resolution scene image, and rendering the virtual scene corresponding to the second scene area by adopting the second resolution to obtain a second resolution scene image.
Specifically, a first virtual camera and a second virtual camera are arranged in the VR device, a first scene area is shot by adopting a first resolution camera, a first scene image generated by first resolution rendering is acquired, a second scene area is shot by adopting a second resolution camera, and a second scene image generated by second resolution rendering is acquired. Wherein, the shooting center points of the first resolution camera and the second resolution camera are the same.
Therefore, scene rendering can be performed through two cameras with different resolutions, so that a first scene image and a second scene image are obtained, and the method is suitable for the situation based on double-camera rendering.
Further, in other embodiments, S120 may specifically include the following steps:
acquiring an initial scene image corresponding to the virtual scene, wherein the resolution of the initial scene image is a third resolution;
and adjusting the third resolution corresponding to the first scene area in the initial scene image to be the first resolution, and adjusting the third resolution corresponding to the second scene area in the initial scene image to be the second resolution, so as to obtain the first scene image and the second scene image. Wherein the third resolution is less than the first resolution and greater than the second resolution.
Specifically, a virtual scene is shot by a third resolution camera in advance in the VR device to obtain an initial scene image, and then high resolution rendering is performed on a first scene area in the initial scene image, that is, the third resolution corresponding to the first scene area in the initial scene image is adjusted to be the first resolution, and meanwhile, low resolution rendering is performed on a second scene area in the initial scene image, that is, the third resolution corresponding to the second scene area in the initial scene image is adjusted to be the second resolution.
Therefore, the first scene image and the second scene image can be obtained by performing high-low resolution rendering on different scene areas after performing scene rendering through one camera, and the method is suitable for the situation based on single-camera rendering.
Therefore, the single camera or the double cameras are adopted to acquire the scene images corresponding to different areas, and the flexibility of the scene image acquisition mode is improved.
In other embodiments of the present disclosure, S110 may specifically include the following steps:
Identifying scene content corresponding to the virtual scene, and determining a background area and a foreground area in the virtual scene;
the foreground region is taken as a first scene region and the background region is taken as a second scene region.
Specifically, the scene content is matched with the predetermined foreground content and background content, and a foreground area or a background area is determined, so that a first scene area and a second scene area are obtained.
Alternatively, the scene content may include a color of the virtual scene, a style of the virtual scene, a layout manner of the virtual scene, motion information and position information of the virtual object, and the like.
Therefore, the foreground area and the background area of the virtual scene are distinguished by analyzing the real scene content, the first scene area and the second scene area are obtained, and for different virtual scenes, different first scene areas and different second scene areas are determined.
Further, the first scene image corresponding to the first scene area and the second scene image corresponding to the second scene area may also be determined in the manner described in the foregoing embodiment, which is not described herein again.
In still other embodiments of the present disclosure, S110 may specifically include the following steps:
Detecting motion information of a virtual object in a virtual scene, and determining a moving object and a static object from the virtual scene based on the motion information;
Determining a first scene area in the virtual scene based on a preset first area dividing parameter by taking the moving object as a center;
And determining a second scene area in the virtual scene based on a preset second area dividing parameter by taking the static object as a center.
The first region dividing parameter is used for determining the radius, the length or the width of the first scene region. The second region division parameter refers to a radius, length, or width for determining the second scene region.
In order for the user to focus on more scene content related to the moving object, the first region-dividing parameter may be greater than the second region-dividing parameter such that the extent of the first scene region is greater than the extent of the second scene region, the moving object being presented to the user through the first scene region, and more scene content related to the moving object being presented to the user.
Therefore, by analyzing the motion information of the real virtual scene, the moving object and the static object are divided into two different areas, and the first scene area and the second scene area are obtained.
Further, the first scene image corresponding to the first scene area and the second scene image corresponding to the second scene area may also be determined in the manner described in the foregoing embodiment, which is not described herein again.
In still other embodiments of the present disclosure, prior to determining the scene area, the method further comprises: setting a first virtual camera and a second virtual camera to shoot in the virtual head-mounted equipment, wherein shooting center points of the first virtual camera and the second virtual camera are the same, a shooting visual field angle of the first virtual camera is a first visual field angle, a shooting visual field angle of the second virtual camera is a second visual field angle, and the second visual field angle is larger than the first visual field angle;
Correspondingly, S110 may specifically include the following steps:
Determining a scene display area of the virtual scene based on the shooting center point and the second view angle;
a first scene area is determined from the scene display areas based on the shooting center point and the first field angle, and an area other than the first scene area in the scene display areas is taken as a second scene area.
The virtual head-mounted device is VR device, and the shooting center point is the lens center point of the virtual camera.
Alternatively, the first field of view may be 40 degrees and the second field of view may be 140 degrees.
Specifically, the first virtual camera and the second virtual camera are concentric cameras, that is, the shooting center points of the two cameras are the same, the virtual scene is shot through a second view angle with a larger value, the maximum display range of the virtual scene is determined as a scene display area based on the shooting center point, meanwhile, the virtual scene is shot through a first view angle with a smaller value, a first scene area is determined from the scene display area based on the shooting center point, and finally, the area except the first scene area in the scene display area is taken as a second scene area.
In case the first virtual camera and the second virtual camera are provided in the virtual head-mounted device, i.e. when the photographed scene renders an image, S120 may specifically comprise the steps of: shooting a virtual scene corresponding to a first scene area by a first virtual camera with a first resolution to obtain a scene image with the first resolution; and shooting a virtual scene corresponding to the second scene area by a second virtual camera with a second resolution to obtain a scene image with the second resolution.
Therefore, two scene areas are determined by using two virtual cameras arranged in the virtual head-mounted equipment, scene shooting is carried out through the two virtual cameras, scene images corresponding to the two areas are obtained, and the method is suitable for the situation based on double-camera rendering.
In summary, in different virtual scenes, the first scene area and the second scene area can be determined in different manners, and the scene image corresponding to each scene area is determined, so that the method can be deployed and applied in different scenes, and the flexibility of the image display method is improved.
