[0051] In view of the technical problem that the maintenance of display models in existing VR product display scenarios is very arduous, this application provides a virtual reality display method, device, equipment, storage medium and product. The overall concept is as follows:

[0052] The method includes: obtaining the coordinates of a target user's current viewing angle acquisition point and item information of multiple items to be displayed, wherein the item information includes a booth identification corresponding to the item to be displayed; for each item to be displayed, according to the booth identification, pasting the corresponding item image onto a booth model to obtain an item display model; projecting a panoramic image of all item display models into a virtual reality space corresponding to the coordinates of the current viewing angle acquisition point to obtain a virtual reality scene; and displaying the virtual reality scene.

[0059] Those skilled in the art will understand that Figure 1The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0060] Based on the above hardware structure but not limited to the above hardware structure, refer to Figure 2 , Figure 2 This is a flowchart of the first embodiment of the virtual reality display method of this application.

[0061] The present invention provides a virtual reality display method, which may include:

[0062] Step S100: obtaining the coordinates of the current viewing angle collection point of the target user and item information of multiple items to be displayed.

[0063] The item information includes the booth identification corresponding to the item to be displayed.

[0064] Step S200: For each item to be displayed, a corresponding item picture is pasted onto the booth model according to the booth identification to obtain an item display model.

[0065] Step S400: Project the panoramic image of all item display models into the virtual reality space corresponding to the coordinates of the current viewing angle acquisition point to obtain a virtual reality scene.

[0066] Step S500: Displaying a virtual reality scene.

[0067] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, such as a virtual reality display device. The following uses a virtual reality display device as an example to illustrate this embodiment and the following embodiments.

[0068] In this embodiment, the items to be displayed can be various commodities in a virtual store within the Metaverse application scenario. A virtual store can include multiple viewpoint acquisition points. For each viewpoint acquisition point, a corresponding virtual reality scene can be constructed to display the virtual store scene from the corresponding perspective to the user. The target user can be any user in the virtual store, and the viewpoint acquisition point at which the target user is currently located can be referred to as the current viewpoint acquisition point. Each viewpoint acquisition point is equipped with a corresponding camera, and the coordinates of the camera can be used as the coordinates of the viewpoint acquisition point.

[0069] When used specifically, the current user coordinates of the target user are obtained, the view acquisition point serial number is matched according to the current user coordinates, and the view acquisition point coordinates of the matched view acquisition point serial number are used as the current view acquisition point coordinates of the target user.

[0070] Item information may include the item ID, item name, item image, corresponding booth ID, and the address of the item details page, where the address of the item details page may be a link to the product details. The booth ID is the booth identifier. It is understood that the 3D model of the virtual store may include at least one display rack, each of which may include multiple booth models. The model information of each booth model may include the corresponding booth ID.

[0071] When generating an item display model, you can match the booth ID in the item information of the item to be displayed with the booth ID in the model information of the booth model. When the booth ID in the item information matches the booth ID in the model information, paste the item image of the item to be displayed on the corresponding booth model, and bind the click event of the booth model to the address of the item details page.

[0072] In a specific implementation, the panoramic image can include the store landscape of all item display models and all display racks in the virtual store photographed at the current viewing angle acquisition point. The panoramic image is projected into the virtual reality space corresponding to the coordinates of the current viewing angle acquisition point, and the virtual reality scene corresponding to the current viewing angle acquisition point can be obtained, so as to show the target user the virtual store scene under the current viewing angle.

[0073] As a specific implementation, before step S400, the method may further include:

[0074] Step S300: constructing a current field of view sphere with the coordinates of the current viewing angle acquisition point as the center of the circle as the virtual reality space.

[0075] In this embodiment, the virtual reality space can be realized through a spherical field of view ball model. For different viewing angle collection points, the coordinates of the viewing angle collection point can be used as the center of the circle, and the radius of the field of view ball model can be determined according to the size of the virtual store to construct a field of view ball as the corresponding virtual reality space.

[0076] In this embodiment, step S400 may include:

[0077] Step S410: Paste the panoramic image onto the virtual reality space to obtain an initial virtual reality scene.

[0078] Step S420: For each item display model, determine the model projection coordinates and vertex relative coordinates of each item display model in the virtual reality space based on the world coordinates, vertex data, and the projection radius of the item display model in the virtual reality space relative to the coordinates of the current viewpoint acquisition point.

[0079] Step S430: adjusting the projection of each object display model in the initial virtual reality scene according to the relative coordinates of all vertices and the projection coordinates of all models to obtain a virtual reality scene.

[0080] In this embodiment, the panoramic image is pasted onto the field of view sphere corresponding to the virtual reality space, and the resulting initial virtual reality scene does not have a three-dimensional sense. Therefore, it is necessary to adjust the coordinates of the object display models in the initial virtual reality scene to adjust the projection of the object display models in the initial virtual reality scene to obtain a virtual reality scene with a three-dimensional sense.

[0081] Among them, the world coordinates and vertex data of the item display model can be the world coordinates and vertex data of the corresponding booth model. The world coordinates and vertex data of the booth model are determined based on the 3D model of the virtual store. It can be understood that the world coordinates of the item display model can be used to determine the position of the item display model in the virtual store, and the corresponding model projection coordinates can be used to determine the position of the item display model in the virtual reality scene; the vertex data of the item display model combined with the world coordinates can be used to determine the shape and size of the item display model, etc. The corresponding vertex relative coordinates can be the coordinates of the vertices of the item display model relative to the model projection coordinates, which are used to determine the shape and size of the item display model in the virtual reality scene. In addition, the projection radius can be determined based on the distance between the current viewing angle acquisition point and the item display model in the 3D model of the virtual store. Therefore, based on the world coordinates, vertex data and projection radius of the item display model, the corresponding model projection coordinates and vertex relative coordinates can be determined.

[0082] Specifically, step S420 may include: determining the model projection coordinates according to the world coordinates, the coordinates of the current viewpoint acquisition point, and the projection radius; determining the vertex world coordinates of the item display model according to the world coordinates and vertex data; determining the vertex projection coordinates of the item display model in the virtual reality space according to the vertex world coordinates, the coordinates of the current viewpoint acquisition point, and the projection radius; and determining the vertex relative coordinates according to the vertex projection coordinates and the model projection coordinates.

[0083] In this embodiment, step S420 may specifically include:

[0084] Using formula 1, the model projection coordinates are determined based on the world coordinates, the coordinates of the current viewing angle acquisition point, and the projection radius; formula 1 is:

[0085] Ps=unit vector of (PO)*r+O;

[0086] Among them, Ps is the model projection coordinate, P is the world coordinate, r is the projection radius, and O is the coordinate of the current viewing angle acquisition point.

[0087] Using formula 2, the world coordinates of the vertices of the item display model are determined based on the world coordinates and vertex data; formula 2 is:

[0088] V1=V+P;

[0089] Among them, V1 is the world coordinate of the vertex, and V is the vertex data.

[0090] Formula 3 is used to determine the vertex projection coordinates of the object display model in the virtual reality space based on the vertex world coordinates, the current viewpoint acquisition point coordinates, and the projection radius. Formula 3 is:

[0091] V1s=unit vector of (V1-O)*r+O;

[0092] Among them, V1s is the vertex projection coordinate.

[0093] Use formula 4 to determine the relative coordinates of the vertex based on the vertex projection coordinates and the model projection coordinates; formula 4 is:

[0094] Vs=V1s-Ps;

[0095] Among them, Vs is the relative coordinate of the vertex.

[0096] This embodiment provides a virtual reality display method. After the item display model is obtained by attaching the item image to the booth identification according to the item information, the item display model is projected into the virtual reality space to obtain a virtual reality scene for display. When the item to be displayed changes, it is only necessary to match the booth identification in the item information with the booth identification of the booth model to achieve the purpose of automatically replacing the item display model in the virtual reality scene. There is no need for the maintainer to manually arrange the item display model for each viewing angle collection point. This solves the technical problem of the existing VR product display scene and the heavy maintenance work of the display model, and reduces the maintenance cost of VR product display.

[0097] In addition, when the item display model with item pictures in this application is projected into the virtual reality space, the item pictures are transformed along with the perspective of the item display model, so that the perspective of the product and the perspective of the booth model in the virtual reality scene are unified, avoiding distortion of the entire virtual reality scene and improving the user experience.

[0098] In addition, in this embodiment, the virtual reality space is realized by a field of view sphere model with the field of view acquisition point as the center of the circle. Using the sphere model to construct the virtual reality scene can reduce the performance loss of the virtual reality display device when rendering the virtual reality scene, and improve the construction efficiency and display efficiency of the virtual reality scene.

[0099] refer to Figure 3 , Figure 3 This is a flow chart of the second embodiment of the virtual reality display method of this application.

[0100] Different from the first embodiment, in this embodiment, step S300 may include:

[0101] Step S310: construct the current field of view sphere with the coordinates of the current viewing angle acquisition point as the center of the circle.

[0102] Step S320: Acquire the coordinates of adjacent perspective collection points of a plurality of adjacent perspective collection points of the current perspective collection point corresponding to the coordinates of the current perspective collection point.

[0103] Step S330: For each adjacent viewing angle acquisition point, an adjacent viewing angle sphere is constructed with the corresponding adjacent viewing angle acquisition point coordinates as the circle center to obtain multiple adjacent viewing angle spheres.

[0104] Step S340: If it is detected that the target user switches from the current viewing angle acquisition point to the target adjacent viewing angle acquisition point, the target adjacent visual field sphere corresponding to the target adjacent viewing angle acquisition point is used as the current visual field sphere to obtain the virtual reality space.

[0105] Correspondingly, step S400 may include:

[0106] Step S440: updating the panoramic image according to the coordinates of the target adjacent viewing angle acquisition points corresponding to the target adjacent viewing angle acquisition points to obtain an updated panoramic image.

[0107] Step S450: Project the updated panoramic image into the virtual reality space to obtain a virtual reality scene.

[0108] In this embodiment, adjacent viewpoint acquisition points are those adjacent to the current viewpoint acquisition point on all sides of the current viewpoint acquisition point. The number of adjacent viewpoint acquisition points can be determined based on actual usage. Preferably, the adjacent viewpoint acquisition points may include those in the front, back, left, and right directions of the current viewpoint acquisition point. The center of the adjacent viewpoint sphere is the coordinate of the adjacent viewpoint acquisition point, and the radius of the adjacent viewpoint sphere is the same as the radius of the current viewpoint sphere.

[0109] When the target user's perspective collection point switches, the target user's perspective collection point after switching is the target adjacent perspective collection point. At this time, the target adjacent vision ball corresponding to the target adjacent perspective collection point can be switched to the current vision ball to build a virtual reality scene and show the virtual store to the target user.

[0110] It can be understood that when the target user's perspective acquisition point is switched, the virtual store scene seen by the target user will change accordingly. Therefore, it is necessary to take a new panoramic image at the target adjacent perspective acquisition point after the switch to update the panoramic image and project it onto the target adjacent field of view sphere to obtain the virtual reality scene after the perspective acquisition point is switched.

[0111] It should be noted that after the target adjacent field of view sphere is used as the current field of view sphere, multiple adjacent field of view spheres of the current field of view sphere can be constructed for use when the target user switches the viewing angle acquisition point subsequently.

[0112] In this embodiment, after step S344, the method may further include: displaying the current field of view ball and hiding other field of view balls except the current field of view ball.

[0113] In this embodiment, the current view sphere can be used to display the virtual store scene seen from the current viewing point. Therefore, when actually displaying it to the target user, only the current view sphere needs to be displayed, and the other view spheres outside the current view sphere are hidden. The other view spheres are all view spheres adjacent to the current view sphere.

[0114] This embodiment provides a virtual reality display method. By constructing multiple adjacent field of view balls, when the field of view acquisition point of the target user changes, the virtual reality scene can be quickly obtained through the adjacent field of view balls and displayed to the user. When the target user is visiting a store, fast and smooth field of view switching can be achieved, thereby improving the user experience.
