It is further worth noting that the order of the steps in the various embodiments of the present invention can be adjusted, and it is not necessary to execute them in the following order.

The embodiment of the present invention provides an image switching display method, which can be applied to virtual reality devices, such as single/binocular virtual reality glasses, single/dual display virtual reality glasses, and the like. The method provided by the embodiment of the present invention can also be applied to an image switching display device running on a virtual reality device, and the device can be application software for image switching, and a functional plug-in of related software.

It should be noted that, in this embodiment, the above-mentioned image switching refers to the mutual switching between the image plane display mode and the 360-degree panoramic display mode.

As shown in Figure 1, the method provided by the embodiment of the present invention includes the following steps:

S101: In response to a first switching instruction indicating to switch from a planar display mode to a panoramic display mode, draw a virtual spherical model with the user's location as the center of the sphere, and the inner surface of the virtual spherical model includes N grids.

When a virtual reality device plays multimedia images, it can often be displayed in two modes: flat display and panoramic display, and the two modes are suitable for different needs. In the flat display mode, the multimedia is displayed in a flat effect, and the experience it brings is the same as that of a 2D display device; in the panoramic display mode, the images can form a space, and the user is in the above space, so that they can get better immersion style experience. In practical applications, it may be necessary to switch between the flat display mode and the panoramic display mode.

If the user wishes to obtain a better immersive experience, a first switching instruction may be issued to switch from the planar display mode to the panoramic display mode. Optionally, the user may issue the first switching instruction through operations such as voice, pressing a button, or posing a certain shape of the body. Certainly, the first switching instruction is not limited to being sent by the user, and may also be sent by the device itself at regular intervals.

When the first switching instruction is received, a virtual sphere model is established with the user's location as the center of the sphere. It can be understood that the inner surface of the virtual sphere model is used to display the image to be rendered. Specifically, the inner surface of the virtual sphere model includes N grids, and the image to be rendered can be rendered on the grids. Wherein, N is an integer, N>1. Optionally, the grid may be a triangular grid, a rhombus grid, a rectangular grid composed of two triangular grids, and the like.

S102: Increasing the grids occupied by the image to be rendered step by step until the image to be rendered occupies N grids, so that the image to be rendered is rendered in each determined grid.

Optionally, increasing the grid occupied by the image to be rendered is actually a process of enlarging the image to be rendered, and the method of enlarging the image to be rendered may use an interpolation method.

Optionally, the process of successively increasing the grids occupied by the image to be rendered may be: at the first moment, the image to be rendered is rendered in M1 grids among the N grids; Images to be rendered are rendered in M2 grids in the grid, wherein M1 and M2 are integers, and N>=M2>M1>1. The first moment may be the moment of the first rendering after receiving the first switching instruction, and at this time, the second moment may be a moment after the moment of the first rendering. Of course, the first moment can also be the second, third, fourth, ..., rendering moment, corresponding to the first moment, the second moment can be the second, third, fourth, ..., the moment after the rendered moment.

When the first moment is the first rendering moment, the value of the number M1 of grids occupied by the image to be rendered may be 1, and at this time M2 may be 4, that is, M2=4*M1. Of course, the values of M1 and M2 may also have other relationships, which are not listed in this embodiment.

A specific example is given below to introduce the above-mentioned sequential rendering process in detail. As shown in Figure 2, assuming that the grid is a rectangular grid, the number of grids occupied by the image to be rendered at the moment of the first rendering is 1, the number of grids occupied by the second time is 4, and the number of grids occupied by the image at the third time is The number of grids occupied this time is 16... until the number of grids occupied by the image to be rendered is equal to N, that is, the image to be rendered fills the entire virtual spherical model.

After determining the number M1 of grids, it is necessary to further determine the positions of the M1 grids. Optionally, it can be determined in the following manner: among the N grids, K grids corresponding to the preset direction are determined, where K is an integer, M1<K<N; M1 located in the center is obtained from the K grids grid. Specifically, the direction of a certain point on the virtual sphere model relative to the center of the sphere may be predetermined as the preset direction. Optionally, the preset direction may be as shown in FIG. 3 . Furthermore, the grids within a certain set angle θ around the preset direction are the K grids corresponding to the preset direction. For example, as shown in FIG. 4 , the grids in the shaded area in FIG. 4 are grids corresponding to the preset directions.

Optionally, M1 grids may also be determined in the grids corresponding to the orientation of the user, so as to render the image to be rendered in the above M1 grids.

For the locations of the M2 grids, optionally, the locations of the M2 grids include the locations of the M1 grids, that is, after determining the locations of the M1 grids, then the Add M2-M1 grids around the grid to determine the positions of the M2 grids. Specifically, the positions of the M2 grids may be determined in the grids in the area centered on the M1 grids.

It can be seen that in this embodiment, in response to the first switching instruction, in the process of switching from the planar display mode to the panoramic display mode, the grids occupied by the image to be rendered and distributed on the inner surface of the virtual spherical model are gradually increased, and each The image to be rendered is rendered in the grid determined next time until the image to be rendered occupies all the grids of the virtual spherical model, then the switching is completed. In the actual display process, the user is at the center of the virtual sphere model, so from the user's point of view, the image to be rendered is gradually enlarged during the switching process until it fills the entire inner surface of the virtual sphere model to form a panoramic effect, thereby better connecting The switching between the plane display mode and the panoramic display mode improves user experience.

An optional implementation manner is enumerated below, and the process of determining the N grids of the virtual sphere model in step S101 is introduced in detail. As shown in Figure 5, this embodiment may include the following steps:

S201: Determine N sides according to a reference side in the virtual sphere model and a preset angle variation, wherein the reference side is a radius of the virtual sphere model.

As shown in Figure 6, assuming that a radius in the horizontal direction of the virtual sphere model is used as the reference side, the reference side is rotated in all directions with the center of the sphere as the center. When rotating in a fixed direction, the rotation angle increases by the preset angle Then one side is determined until N sides are determined. For example, as shown in FIG. 6 , the preset angle is 90 degrees, and the reference edge is rotated in both vertical and horizontal directions, then the N sides can be shown as dashed lines in FIG. 6 , which are respectively n1-n6.

S202: Use the intersection points of the N sides and the sphere of the virtual sphere model as vertices, and determine N rectangular grids in combination with preset side lengths.

It should be noted that, in this embodiment, the grid may be a rectangular grid, but the shape of the grid is not limited to the rectangular grid listed in this embodiment.

Optionally, the vertices may correspond to a point at the upper left corner, a point at the upper right corner, a point at the lower left corner, and a point at the lower right corner of the rectangular grid. It is worth noting that if it is specified that the vertices correspond to the points at the lower left corner of the rectangular grid, then in this determination process, each vertex is used as the point at the lower left corner to determine the rectangular grid.

In practical applications, there may also be a need to switch from the panoramic display mode to the flat display mode. If you want to complete the above switch, the user can send a second switch command, and in response to the second switch command, gradually reduce the proportion of the image to be rendered. The grid until the image to be rendered occupies a grid, so that the image to be rendered is rendered in each determined grid. It can be understood that successively reducing the grid occupied by the image to be rendered is essentially a process of shrinking the image to be rendered. Optionally, the image to be rendered can be reduced by downsampling. The switching process in this embodiment is essentially the inverse process of step S102 in the embodiment shown in FIG. 1 , and will not be repeated here.

The rendering module 720 is configured to gradually increase the grids occupied by the images to be rendered until the N grids are occupied by the images to be rendered, so as to render the images to be rendered in each determined grid.

It can be seen that during the switching process, the user can see the effect that the image to be rendered is gradually enlarged until it fills the entire inner surface of the virtual sphere model, and this embodiment can better connect the switching between the planar display mode and the panoramic display mode, and further Improved user experience.
