The following description is made with reference to specific embodiments, and with reference to the components and specific workflow of the virtual reality game system:

the iris login module 101 is configured to acquire an iris image of a user every preset time period, extract multidimensional iris features of the iris image, and verify a login identity of the user according to the multidimensional iris features by using a multi-item matching decision-making method.

In one practical application scenario of the invention, in the existing game system, when a user logs in an account, information such as an account name, a password and the like is often required to be input for identity authentication; or, in order to ensure the security of the account, most companies and enterprises need to perform verification of the verification code after inputting information such as the name of the account and the password to confirm the identity of the user, so that the login process of the current game system is complicated, and the joint authentication through the information such as the name of the account, the password and the verification code still has a large security risk, so that the account is falsely signed by others to log in, and the security and the simplicity can not meet the requirements of most users.

In the embodiment of the invention, the iris login module 101 can be used for acquiring the iris image of the user every other preset time period and extracting the texture characteristics of the iris changing image so as to carry out regular identity verification on the user using the game changing system according to the texture characteristics, so that the process of manually inputting and inputting information such as account name, password, verification code and the like by the user is omitted, and the process of user identity verification is simplified; meanwhile, through iris verification every other preset time period, the method prevents other people from stealing account information to log in by impersonation, protects account safety, performs identity verification every other preset time period, also prevents other people from completely controlling the account for a long time after logging in by impersonation with the account once, and further improves account safety.

In the embodiment of the present invention, the iris image refers to an image of a pupil area of an eye of a user, and the iris image may be obtained by performing operations such as scanning or shooting on the eye area of the user through a virtual reality device (such as VR glasses, VR helmet, etc.) used/worn by the user.

In detail, in order to realize accurate verification of the login identity of the user, the texture features of the iris image can be extracted from multiple dimensions, the diversity of the extracted multidimensional iris features is ensured, and the quantity of feature information in the multidimensional iris features is increased so as to realize accurate analysis of the iris image; furthermore, the login identity of the user is verified according to the extracted multidimensional iris features by utilizing a multi-item matching decision mode, so that the verification error caused by the single decision contingency in the verification process is avoided, and the accuracy of login identity verification is improved.

In the embodiment of the present invention, when extracting the multidimensional iris feature of the iris image, the iris registration module 101 is specifically configured to:

calculating first pixel gradients of each pixel point in the iris image in preset N directions according to the plane coordinates in a non-down sampling contourlet transformation mode, and calculating second pixel gradients of each pixel point in the iris image in preset N directions according to the plane coordinates in a non-down sampling shear wave transformation mode;

In detail, the non-downsampling contourlet transformation means that a non-downsampling pyramid filter set of scale decomposition is utilized to decompose the low-frequency component of each pixel point in the iris image into a low-pass sub-band and a high-frequency sub-band; and meanwhile, decomposing the high-frequency component of each pixel point in the iris image and the high-frequency sub-band obtained by decomposing the low-frequency component by using a non-downsampling filter group for directional decomposition to obtain a band-pass directional sub-band, and calculating the first pixel gradient of each pixel point in the iris image in the preset N directions by using the decomposed low-pass sub-band and the band-pass directional sub-band.

Specifically, the non-downsampling shear wave transformation means that when the shear wave transformation is applied to process an iris image, a multiscale decomposition of the image is obtained through a practical non-downsampling laplacian tower filter bank by using a discrete form, and then the direction decomposition is performed on the obtained subband images of all scales by using the shear wave filter combination, so that subband features of different scales and different directions are obtained, and first pixel gradients of each pixel point in the iris image in preset N directions are calculated.

In detail, the first feature channel and the second feature channel are feature channels constructed by using a feature detection operator in advance, and extraction of different types of features in the iris image can be realized.

For example, when the feature to be extracted from the iris image is a corner feature, a feature channel may be constructed by using a corner detection operator (e.g., harris operator, SUSAN operator, CSS operator, features from obtained segment operator, etc.); when the features to be extracted from the iris image are speckle features, a feature channel can be constructed by using a speckle detection operator (such as a DoG operator, a Multi-Scale Harris operator, a SIFT operator, a SURF operator, and the like).

The features of different feature channels can be mapped to different levels of a preset feature pyramid network respectively, and then the first region features and the second region features mapped to the feature pyramid network are fused from top to bottom layer by layer to obtain the local features of the iris image.

In the embodiment of the invention, the local features of the iris image are identified in a dual-channel fusion feature identification (the first feature channel and the second feature channel) mode, so that the accuracy of the identified local features is improved, and the content of feature information in the local features is increased, so that the accuracy of the final login identity authentication is improved.

Furthermore, in order to accurately identify the login identity of the user according to the extracted multidimensional iris features, the multidimensional iris features can be compared with the pre-stored iris features of the user, and the login identity of the user can be confirmed according to the comparison result.

In the embodiment of the present invention, when the iris login module 101 verifies the login identity of the user according to the multidimensional iris feature by using a multi-item matching decision, the iris login module is specifically configured to:

creating a comparison thread according to the number of user login identities stored in a database corresponding to the game system;

selecting one user login identity from the user login identities one by one as a target identity, and establishing a multi-item cross-comparison relationship between each feature in the user iris features corresponding to the target identity and each feature in the multidimensional iris features, wherein the multi-item cross-comparison relationship comprises a pairwise corresponding comparison relationship between each feature in the user iris features and each feature in the multidimensional iris features;

synchronously and parallelly calculating the similarity between the iris features of the user corresponding to all the login identities of the user and the multi-dimensional iris features by using the comparison thread, and selecting the login identity of the user with the maximum similarity as the predicted login identity of the user;

In detail, by creating the comparison threads with the same number of the user login identities stored in the database, the synchronous comparison of all the stored user identities can be realized, and the efficiency of login identity verification of the user can be improved.

Specifically, by establishing a multi-item cross-comparison relationship between each feature in the user iris features corresponding to the target identity and each feature in the multi-dimensional iris features, the comprehensive comparison between each feature in the user iris features corresponding to the target identity and each feature in the multi-dimensional iris features can be realized, so that the omission of comparison is prevented, and the accuracy of identity verification is improved.

And synchronously and parallelly calculating the similarity between the user iris features corresponding to all the user login identities and the multi-dimensional iris features by utilizing the comparison thread through a preset similarity algorithm, wherein the similarity algorithm comprises but is not limited to a cosine distance algorithm, an Euclidean distance algorithm and the like.

In the embodiment of the invention, the login identity of the user can be efficiently and accurately verified in a multi-item matching decision mode, and the use experience of the user is improved.

The game module 102 is configured to obtain play information of the user according to the verified login identity, call sharing evaluation data of the user from the sharing evaluation module, recommend a game to the user according to the play information and the sharing evaluation data, and start a game in response to a start instruction of the user.

In this embodiment of the present invention, the game module 102 may obtain playing information of the user according to the login identity verified by the iris login module 101, where the playing information includes information, such as a game name, a game category, and a game time, corresponding to a game played by the user in a historical time period corresponding to the login identity.

Further, the game module 102 may also call, from the sharing evaluation module 105, sharing evaluation data of the user corresponding to the login identity for different games through a computer sentence (such as a java sentence, an SQL sentence, and the like) having a data call function.

Preferably, in the embodiment of the present invention, the sharing evaluation data is recommendation degrees of sharing behaviors and plays of different games by the user corresponding to the login identity.

In the embodiment of the present invention, the game module 102 may implement accurate game recommendation on the user by analyzing the playing information and the shared evaluation data, so as to improve user stickiness and improve user experience.

In an embodiment of the present invention, when the game module 102 recommends a game to the user according to the play information and the sharing evaluation data, the game module is specifically configured to:

generating a preset number of subset matrixes of the preference matrix by utilizing random sampling, and respectively extracting characteristic elements of each subset matrix in a plurality of subset matrixes;

In one practical application scenario of the invention, because the user does not necessarily play each owned game, but selects a part of the acquired multiple games for playing according to factors such as own requirements or preferences, the preference of the user to the target game can be calculated according to the playing duration of the target game and the playing recommendation of the user to the target game, and a preference matrix is generated, which is beneficial to improving the preference degree of the user to different games by using the preference matrix subsequently, thereby improving the accuracy of game recommendation.

In detail, the empty element matrix, i.e. the matrix with all 0 elements, can be created by a B = zeros (m, n) function in the R language library with m rows and n columns.

Specifically, the calculating the preference degree of the user for the target game according to the playing duration of the target game and the playing recommendation degree of the user for the target game comprises the following steps:

calculating the preference degree of the user to the target game by using the following preference degree function:

wherein the content of the first and second substances,

for the user's preference for the target game,

for the user's play duration of the target game,

recommending the playing degree of the target game for the user.

In the embodiment of the invention, the preference degree of each game in the plurality of games can be used as an element to be filled into the empty element matrix, and then the preference matrix is obtained.

In one practical application scenario of the present invention, since the preference matrix includes the preference degree corresponding to each game of the plurality of games, if the preference of the user for each game of the plurality of games is directly analyzed according to the preference matrix, some games with higher preference degrees in the matrix will have a greater influence on the analysis result, which results in an incomplete analysis result, and further results in a lower accuracy of game recommendation for the user according to the analysis result.

Therefore, the embodiment of the invention can randomly sample the elements in the preference matrix for multiple times according to the preset number to obtain multiple subset matrixes of the preference matrix, thereby avoiding the influence of part of games on other games in the matrix due to overhigh calculated preference.

In detail, the generating a preset number of subset matrices of the preference matrix using random sampling includes: randomly sampling elements in the preference matrix according to a preset number, and collecting the sampled elements into a subset matrix of the preference matrix; judging whether the number of the subset matrixes is equal to a preset threshold value or not; if the number of the sampling elements is not equal to a preset threshold value, returning to the step of randomly sampling the elements in the preference matrix according to the preset number; if the number of the sampling elements is equal to the preset number, all the subset matrixes are collected into a plurality of subset matrixes of the preference matrix.

Specifically, in the embodiment of the present invention, a pre-trained deep neural network may be used to extract feature elements of each of a plurality of subset matrices, where the pre-trained deep neural network includes, but is not limited to, an XGboost-based deep neural network, a random forest-based deep neural network, and the like.

In the embodiment of the invention, the characteristic elements of each subset matrix in the plurality of subset matrices can be respectively extracted, so that the characteristic element extraction from the preference matrix is avoided, the influence on the extraction result of the characteristic elements caused by the overhigh preference degree of the game corresponding to part of the characteristic elements is favorably reduced, the comprehensiveness of the obtained characteristic elements is improved, and the accuracy of analyzing the preference degree of the user on different games according to the extracted characteristic elements is favorably improved.

In the embodiment of the present invention, because the feature elements are obtained by performing feature extraction on different subset matrices, when the frequency of occurrence of a certain feature element is more, it can be considered that the feature weight of the feature element in the feature elements of all subset matrices is larger, that is, it can be considered that the preference degree of the user for the game corresponding to the feature element is larger.

Therefore, the occurrence frequency of each element in the feature elements can be counted, the occurrence frequency is used as the weight of the feature elements, the game with the feature weight larger than a preset weight threshold value is taken as the preference game of the user, and the game with the same game category as the preference game is recommended to the user.

The embodiment of the invention can generate the preference matrix according to the acquisition times and the use times of different games by the user so as to screen the games preferred by the user from various games according to the preference matrix, thereby improving the accuracy of game recommendation for the user, and when the games are screened by using the preference matrix, the preference matrix is sampled to generate a plurality of subset matrixes, thereby avoiding the problem that the screening result is influenced by overhigh preference degree of part of games and further improving the accuracy of game recommendation for the user.

In this embodiment of the present invention, the game module 102 starts the game in response to the start instruction of the user.

The virtual scene rendering module 103 is configured to perform virtual reality picture rendering modeling according to the game started by the game module, so as to obtain a virtual game scene.

In the embodiment of the present invention, in order to display a virtual reality game scene for a user, the virtual scene rendering module 103 may perform rendering modeling of a virtual reality picture according to a game started by the game module 102, so as to obtain a virtual game scene.

In the embodiment of the present invention, when the virtual scene rendering module 103 performs virtual reality picture rendering modeling according to the game started by the game module to obtain a virtual game scene, the virtual scene rendering module is specifically configured to:

acquiring game data of a game started by the game module 102, and extracting object form data and object relation data in the game from the game data;

In detail, the object shape data refers to data such as shapes, sizes, colors, and the like of different objects in the game started by the game module 102; the data of the relationship between the objects refers to data such as a position relationship, a distance, a combination relationship, and the like between different objects in the game started by the game module 102.

Therefore, the 3D virtual models of each object can be laid out and placed in the pre-constructed virtual game space according to the object shape data and the relationship data between the objects, so as to obtain an initial virtual scene.

Furthermore, the embodiment of the invention can divide the constructed different 3D virtual models to obtain a plurality of model sub-blocks, and then perform personalized rendering on each model sub-block according to the personalized modification preference of the user on each model sub-block, thereby realizing personalized and open virtual scene display on the user and obtaining the virtual game scene.

For example, a 3D virtual model of a character a exists, the 3D virtual model of the character a may be divided into a plurality of model sub-blocks according to different body parts, for example, the 3D virtual model of the character a is divided into a plurality of model sub-blocks such as eyes, hair, nose, skin, and clothes, and further, diversified elements such as different eye shapes, hair colors, and nose positions may be selected to perform personalized rendering on the character a according to personalized modification preference of a user for each model sub-block, thereby obtaining a virtual game scene.

In the embodiment of the present invention, the virtual scene rendering module 103 implements an open and personalized display of a virtual scene in a game, and is beneficial to improving the playing experience of a user.
