It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a display method according to an embodiment of the present invention. The embodiment can be applied to the situation of displaying pictures, particularly the situation of displaying panoramic pictures, and the typical method can be applied to the situation of switching and displaying scenes in a virtual reality environment. The method may be performed by a display device, which may be implemented in software and/or hardware, and may typically be virtual reality glasses. Referring to fig. 1, the display method provided in the present embodiment includes:
and S110, acquiring the user fixation point.
Wherein, the gaze point is a gaze point when the user set views the picture, and the point can be represented in the form of coordinates.
Optionally, the determination of the fixation point may be determined by recognizing a photographed face image of the user; or may be determined indirectly by an external sensor.
Specifically, the determination of the fixation point may be described as setting a current position point of the fixation point as an origin of the three-dimensional coordinate system; after moving the fixation point to the next position point, acquiring the motion parameters of the head of the user according to at least one sensor; determining the relative position of the fixation point of the user relative to the origin of the three-dimensional coordinate system according to the motion parameter; and determining the position coordinates of the three-dimensional coordinate system according to the relative position. Wherein the motion parameters may comprise at least a displacement and a rotation angle.
And S120, determining a visual range according to the fixation point.
Wherein the visual range is an effective scene range which can be seen by the user with the gaze point as a center. The visible range is determined by the angle of visibility of the person.
Typically, the visible range is a range in which the left and right angles are set around the fixation point. Wherein, the setting angle can be set according to actual need.
Typically, since the angle of visibility of the human eye is generally 120 degrees, the range of 60 degrees on the left and right sides around the fixation point can be used as the visible range.
And S130, loading and displaying the target picture from the part of the target picture positioned in the visual range.
In the prior art, a target picture is usually loaded and displayed in a pixel-by-pixel manner from an origin of the target picture, where the origin of the target picture is an upper left corner of the picture.
In this embodiment, a portion of the target picture within the visible range is loaded and displayed first, and then other portions of the target picture are loaded and displayed. It can be understood that the loading and displaying manner of the target picture enables the user to see the picture as soon as possible by first presenting the picture portion within the visual range of the user for the picture with a larger size that cannot be traversed at a glance. Typically, the picture may be a panoramic picture.
According to the technical scheme of the embodiment of the invention, the part of the target picture within the visual range is loaded and displayed firstly, and then other parts of the target picture are loaded and displayed. Therefore, the picture part in the visual range is firstly displayed to the user, so that the user can see the picture as soon as possible, and the display speed of the target picture is improved on the premise of not sacrificing the display resolution of the target picture.
In order to further improve the display speed and resolution of the target picture, before loading and displaying the target picture from the target picture portion located in the visual range, the method further comprises:
and determining the resolution of the target picture according to the current network state.
Specifically, if the current network state is greater than the set network speed threshold, the resolution of the target picture may be set to be slightly larger; if the current network status is not greater than the set network speed threshold, the resolution of the target picture may be set slightly smaller.
In order to further increase the loading and displaying speed of the target picture, starting from the target picture portion located in the visual range, loading and displaying the target picture may include:
and starting from a first display picture part and a second display picture part which are positioned in the visual range, respectively loading the first display picture and the second display picture to the outer surface and the inner surface of a set visual model, wherein the resolution of the first display picture is smaller than that of the second display picture, and the contents of the first display picture and the second display picture are the same as the display contents of the target picture.
Optionally, if the current network state is greater than the set network speed threshold, the first display picture and the second display picture may be loaded to the outer surface and the inner surface of the set visual model, respectively, starting from the first display picture portion and the second display picture portion located in the visual range at the same time. Because the resolution of the first display picture is smaller than that of the second display picture, the first display picture portion within the visual range is first loaded to complete the display quickly. The user can quickly see the display content of the target picture through the first display picture part positioned in the visual range. Thereby further improving the display speed of the target picture.
If the current network state is not larger than the set network speed threshold value, loading and displaying a first display picture part positioned in the visual range to the outer surface of the set visual model; then loading and displaying a second display picture part positioned in the visual range to the inner surface of the set visual model; and finally, loading and displaying other parts in the first display picture and the second display picture respectively.
Wherein, the display speed of the target picture can be improved by loading and displaying the part of the first display picture positioned in the visual range; by loading and displaying a portion from the second display picture within the visible range, the display resolution of the target picture can be guaranteed. Optionally, there may be other combinations of the display orders of the first display picture portion, the other portion of the first display picture, the second display picture portion and the other portion of the second display picture within the visual range, which are not listed in this embodiment due to space limitations.
In order to further increase the display speed of the target picture, before starting from the first display picture portion and the second display picture portion located in the visual range, the first display picture and the second display picture are respectively loaded on the outer surface and the inner surface of the set visual model, the method may further include:
and determining the resolution of the first display picture and the resolution of the second display picture according to the current network state.
Typically, if the current network state is greater than the set network speed threshold, the resolution of the first display picture and the resolution of the second display picture may be set slightly larger, so as to improve the display resolution of the target picture while ensuring the display speed of the target picture.
If the current network state is not larger than the set network speed threshold value, the resolution of the first display picture and the resolution of the second display picture can be set to be slightly smaller so as to ensure the display speed of the target picture.
Optionally, the target picture may be a combination of slices of at least one target picture. When the target picture is a slice sequence of the target picture formed by combining a plurality of slices, loading and displaying the target picture from a target picture part located in the visual range may include:
starting from the partial slice of the target picture located in the visual range, loading and displaying the slice sequence of the target picture.
Typically, the slice sequence of the target picture is a set level tile map of the target picture.
The display method for the target picture can be applied to switching between the current scene and the target scene. Specifically, before loading and displaying the target picture from the portion of the target picture located in the visual range, the method may further include:
when a current scene picture is displayed, determining adjacent scenes according to a preset position relation of the current scene;
responding to a target scene trigger event, determining a target scene from the adjacent scenes, and taking a picture of the target scene as the target picture;
and in the process of scene switching animation playing, loading the target picture to a cache.
During the playing process of the scene switching animation, loading the preset target picture to a cache, so that the loading and displaying efficiency of the preset target picture is further improved; the preset position relation is the relation between the geographic position corresponding to the current scene and the geographic position corresponding to other scenes, and the adjacent scenes in the geographic positions are taken as the adjacent scenes.
Alternatively, the target scene trigger event may be any trigger event for determining a target scene from adjacent scenes, and specifically may be a displacement event with a set direction.
It should be noted that, through the above teaching, a person skilled in the art may motivate the implementation of any combination of the above-described embodiments, and this embodiment will not be described in detail herein.
Example two
Fig. 2 is a flowchart of a display method according to a second embodiment of the present invention. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the display method provided in this embodiment includes:
s210, when the current scene picture is displayed, the adjacent scene is determined according to the preset position relation of the current scene.
S220, determining a target scene from the adjacent scenes according to a target scene trigger event, and taking a picture of the target scene as a target picture.
And S230, determining the tile maps of the set levels of the target pictures of different levels as the first display picture and the second display picture according to the current network state.
Specifically, the target picture adopts a multi-level tile map structure, the resolution is from low to high, and the corresponding number of tiles is increased gradually. The lower level ensures the display speed and the higher level ensures the display effect.
The tile map is obtained by dividing a high-resolution panoramic picture into a plurality of small pictures with the same size from left to right and from top to bottom. The content of the target picture with lower resolution and the content of the target picture with high resolution are the same, and the difference is that the resolution is different.
For example, the resolution of the low-resolution target picture is: 512X 256 pixels, the resolution of the high resolution target picture is: 4096X 2048 pixels, the high resolution target picture is divided into 32 tile maps with resolution 512X 512 pixels according to 4 rows and 8 columns. The multi-level tile map structure of the target picture is that 1 panoramic picture with the resolution of 512X 256 pixels (as the first level) +2 tile maps with the resolution of 512X 512 pixels (as the second level) +8 tile maps with the resolution of 512X 512 pixels (as the third level) +32 tile maps with the resolution of 512X 512 pixels (as the fourth level) +128 tile maps with the resolution of 512X 512 pixels (as the fifth level).
For example, if the current network status is better, the following may be adopted: a second level tile map as a first display picture + a fourth level tile map as a second display picture; if the network status is poor, the following steps can be adopted: the first level tile map is used as a strategy of the first display picture + the third level tile map is used as a second display picture.
S240, in the process of playing the scene switching animation, namely when the current scene is switched with the target scene, the first display picture and the second display picture are loaded to a cache.
Typically, when a user switches from a current scene to a target scene in a virtual reality scene, a scene transition animation is played first to make the scene switching more natural, and a picture to be displayed is cached by using the time of playing the animation.
And S250, acquiring a user fixation point, and determining a visual range according to the fixation point.
And S260, starting from a part of tile map in the first display picture and a part of tile map in the second display picture which are positioned in the visual range, respectively loading the first display picture and the second display picture which are positioned in the cache to the outer surface and the inner surface of the set visual model.
The setting visual model may be any shape, and may typically be a sphere.
Illustratively, when the second-level tile map is used as the first display picture and the fourth-level tile map is used as the display strategy of the second display picture, the fourth-level tile map is divided into 4 rows and 8 columns, each column of the pictures occupies a viewing angle of 360 degrees/8 columns of 45 degrees/column, and the visible range is 60 degrees by 2 degrees to 120 degrees, that is, the user can only see 3 columns of the pictures at most (120 degrees/45 degrees/column equals to about 3 columns) at a time, and if the current visible range of the user is three columns of the pictures, the three columns of the pictures are preferentially loaded as the partial tile maps in the second display picture in the visible range. The scene in the visual range of the user will become momentarily clear (because the high resolution inner texture covers the outer texture).
And S270, taking the target picture as a current scene picture, returning to continuously executing the step of determining the adjacent scene according to the preset position relation of the current scene when the current scene picture is displayed.
Typically, when the present embodiment is applied to scene switching of virtual reality, the target picture is displayed quickly and with high resolution. The delay sense that virtual reality panorama roaming produced when showing the picture has effectively been reduced, lets the user have the sensation of being personally on the scene, and the improvement of immersive browsing experience can show the long duration of use that improves virtual reality panorama roaming.
According to the technical scheme of the embodiment of the invention, the first display picture and the second display picture are loaded to the cache in the process of switching the animation playing, so that the loading speed of the two pictures is increased; dynamically adjusting a display strategy of the target picture according to the network condition of the user so as to improve the display speed and resolution of the target picture as much as possible by combining with the actual situation; in addition, the spherical model is adopted to take the low-resolution target picture as an outer texture and the high-resolution target picture as an inner texture, so that the loading speed and the display resolution of the target picture are further improved.
