Description

Technical Field

[0001] The present application relates to the field of automobile information technology, and specifically to a virtual image display method, device and equipment. Background Art

[0002] 3D modeling technology is to use 3D production software to build a model with 3D data in a virtual 3D space. 3D modeling technology is applied in many fields. For example, in the field of games, 3D modeling technology provides game designers with powerful tools to create virtual images, thereby enhancing the realism and immersion of the game.

[0003] 3D modeling technology can also be applied to the car computer. The car computer uses 3D modeling technology to complete the generation of virtual images and display them on the car computer to better achieve interaction with users and improve the interactivity and fun of car computer operations.

[0004] In the traditional gaming industry, avatar modeling often requires a high degree of detail and realism to enhance the player's immersive experience. This means that modelers need to pay attention to every detail of the avatar, including bones, textures, lighting effects, materials, etc. At the same time, based on the high computing power of electronic devices, the gaming industry usually requires very sophisticated avatar generation.

[0005] Unlike the virtual image modeling in the traditional game industry, the computing power of the car computer is low and cannot support the direct transplantation of the modeling methods of the game industry. If too much attention is paid to the modeling details of the virtual image, it will cause problems such as freezing or even crashing of the car computer system. At the same time, since the accuracy requirements for generating virtual images on the car computer are not high, there is no need to pay too much attention to the modeling details of the virtual image, which makes the virtual image modeling on the car computer side inevitably lower than the accuracy of the virtual image modeling in the game industry.

[0006] However, low-precision modeling will cause the avatar to easily penetrate the model when part of the skin and clothing are superimposed, affecting the user experience. In related technologies, in order to solve the problem of avatar penetrating the model, the virtual model skeleton is further refined. However, this is difficult to achieve for the low-computing-power vehicle-mounted end. Summary of the invention

[0007] The embodiments of the present invention provide a method, device and equipment for displaying a virtual image, so as to solve the problem of model penetration that may occur in the virtual image modeling on the vehicle side in the prior art.

Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained according to these drawings without creative efforts.

Detailed implementation manners

[0021] To better understand the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0022] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0023] As Figure 1 shown, a virtual image display method provided by an embodiment of the present invention is shown. Refer to Figure 1 , the specific steps of this method include: S101, when generating a virtual image based on a selected target clothing, determine whether there is an easy-to-penetrate position of the virtual image under the target clothing according to a preset clothing-body correspondence rule.

[0024] Specifically, based on the computing power of the in-vehicle terminal, a humanoid bone model is pre-built for the virtual image as the body model of the virtual image. When generating a virtual image each time, different clothing can be configured for it based on the body model of the virtual image to change the shape of the virtual image.

[0025] The virtual image actually displayed on the in-vehicle terminal is composed of a pre-built body model and the current target clothing configured for it. By rendering the body model and the target clothing, a complete virtual image is generated for display on the in-vehicle terminal. Among them, each time the target clothing for the virtual image is changed, for example, when receiving a dressing change instruction for the virtual image on the in-vehicle terminal, it is necessary to re-render the body model and the updated target clothing to update and generate the virtual image.

[0026] Each time a virtual image is re-rendered and generated based on a selected target clothing, it is necessary to ensure that the generated virtual image does not have a penetration problem under the target clothing.

[0027] When generating a virtual image, determine the current target clothing, and determine whether there is an easy-to-penetrate position of the virtual image under the target clothing according to a preset clothing-body correspondence rule.

[0028] The clothing-body correspondence rule is a set of corresponding relationships between several pieces of clothing and body parts. Among them, the clothing in the clothing-body correspondence rule is the clothing configured for the virtual image and can be used to dress up the virtual image; the body parts are the various parts of the body model of the virtual image, specifically determined after multiple tests, which are the easy-to-penetrate positions of the virtual image under different clothing.

[0029] In a specific embodiment, the clothing-body correspondence rule includes three sets of correspondences between clothing and body parts. The first set is: Clothing 1 - waist, the second set is: Clothing 2 - upper body, and the third set is: Clothing 3 - legs. This indicates that when configuring Clothing 1 for the virtual image and rendering the virtual image, there is a high probability that the waist of the virtual image will conflict with the display of Clothing 1, resulting in the phenomenon of skin exposure and penetration of the model; when configuring Clothing 2 for the virtual image and rendering the virtual image, it is very likely that the upper body of the virtual image will conflict with the display of Clothing 2, resulting in the phenomenon of skin exposure and penetration of the model; when configuring Clothing 3 for the virtual image and rendering the virtual image, it is very likely that the legs of the virtual image will conflict with the display of Clothing 3, resulting in the phenomenon of skin exposure and penetration of the model.

[0030] By querying in the preset clothing-body correspondence rule, it is determined whether there are positions prone to penetration of the model for the virtual image under the current target clothing, and when there are positions prone to penetration of the model for the virtual image, the specific parts prone to penetration of the model.

[0031] S102, when there are positions prone to penetration of the model, render the non-positions prone to penetration of the model and the target clothing among all the body parts of the virtual image.

[0032] Specifically, when it is determined that there are positions prone to penetration of the model for the virtual image under the target clothing, and the specific parts prone to penetration of the model are determined through the clothing-body correspondence rule, then when rendering the virtual image, only render the non-positions prone to penetration of the model and the target clothing among all the body parts of the virtual image, and do not render the positions prone to penetration of the model.

[0033] In a specific embodiment, as Figure 2 shown is a schematic diagram of a virtual image display method provided by an embodiment of the present invention. When selecting Clothing 1 as the target clothing configured for the virtual image, and it is determined through the clothing-body correspondence rule that there are positions prone to penetration of the model, and the position prone to penetration of the model is the waist, then when rendering the virtual image, do not render the waist position, but only render the body model and the target clothing at other positions except the waist. The final virtual image will not have the problem of penetration of the model caused by the conflict between the waist and the clothing display because the waist is not rendered.

[0034] Optionally, when it is determined that there are no positions prone to penetration of the model for the virtual image under the target clothing, that is, there is no record of the position prone to penetration of the model corresponding to the target clothing in the clothing-body correspondence rule, it is determined that the virtual image will not have the problem of penetration of the model under the target clothing, and it is normal to render all the body parts of the virtual image and the target clothing.

[0035] In the embodiment of the present invention, by establishing a clothing-body correspondence rule, the easy-to-wear model positions of the virtual image under different clothing are determined, and through an adaptive transparency adjustment mechanism, the easy-to-wear model positions are set to be transparent under each set of clothing, that is, the easy-to-wear model positions of the virtual image under each set of clothing are not rendered, fundamentally solving the problem of the virtual image penetrating the model, and ensuring that the virtual image on the in-vehicle device will not have the problem of penetrating the model under the condition of low-precision modeling. At the same time, reducing the rendering of the easy-to-wear model positions can also improve the processing ability of the in-vehicle device and enhance the rendering speed.

[0036] Optionally, before executing S101, it is necessary to pre-complete the establishment of the clothing-body correspondence rule so that the easy-to-wear model position of the target clothing can be determined by querying the clothing-body correspondence rule when executing S101.

[0037] Specifically, based on the body model of the virtual image, several sets of clothing are configured for the virtual image. The virtual image is respectively rendered and tested through each set of configured clothing to determine the probability of the penetration of each body part of the virtual image under different clothing. The body parts of the virtual image with a penetration probability higher than the preset value under any clothing are determined as the easy-to-wear model positions, and the corresponding relationship between the clothing and the easy-to-wear model positions is written into the clothing-body correspondence rule. All clothing is tested to establish the clothing-body correspondence rule according to the test results of each clothing.

[0038] Among them, when establishing the clothing-body rule, in order to ensure the accuracy of the test results and ensure that the detected easy-to-wear model positions will not be interfered by accidental results, when testing any piece of clothing, it is necessary to perform no less than the first number of tests on the body model of the virtual image through this clothing. Then, according to the number of tests and the number of times of penetration of each part of the virtual image body model under this clothing, the probability of penetration of each body part of the virtual image under this clothing is determined.

[0039] In a specific embodiment, the preset value of the probability is set to 10%, and the first number is set to 100. Clothing 1 is tested, and 100 renderings are performed on Clothing 1 and the body model of the virtual image. Among them, there are 15 times of penetration of the waist, then the waist is determined as the easy-to-wear model position, and Clothing 1 - Waist is written into the clothing-body correspondence rule. Other clothing is tested in the same way to complete the construction of the clothing-body preset rule.

[0040] Optionally, in some embodiments, the penetration of the virtual image can also be avoided by setting the action range.

[0041] Specifically, after the virtual image is rendered and generated, the virtual image can perform some preset actions to complete the interaction operation with the user. When the virtual image needs to perform a preset action, it is necessary to determine the body parts that need to move for the preset action, such as the arms, head, legs, etc. Determine the action range of the body parts, and make the body parts perform the corresponding preset actions within the action range.

[0042] Among them, the action range is the action range where the body parts will not overlap with other body parts when performing the preset action.

[0043] In the embodiment of the present invention, by setting the action range, the problem of model penetration caused by the overlap of body parts when the virtual image performs a preset action is avoided.

[0044] Corresponding to the above virtual image display method, an embodiment of the present application also provides a virtual image display device. Refer to Figure 3 , which is a schematic structural diagram of a virtual image display device provided by an embodiment of the present application. The virtual image display device may include: a determination module 301 and a rendering module 302.

[0045] The determination module 301, when generating a virtual image based on the selected target clothing, determines whether there are any positions prone to model penetration on the virtual image under the target clothing according to the preset clothing-body correspondence rule.

[0046] The rendering module 302, when there are positions prone to model penetration, renders the non-positions prone to model penetration among all the body parts of the virtual image and the target clothing.
