[0061] Reference Figure 2 , the embodiment of the present application provides a method for adjusting the angle of a cloud game strategy screen, the method for adjusting the angle of a cloud game strategy screen comprising:

[0062] Step S100, obtaining the strategy screen perspective and the character perspective;

[0063] Step S200, determining perspective change information based on the strategy screen perspective and the character perspective;

[0064] Step S300: adjusting the strategy screen based on the perspective change information.

[0065] In this embodiment, the specific application scenario may be:

[0066] After the character enters the teaching level in the game, the game teaching video only provides fixed videos or pictures for the specified game scene. The angle of the teaching video cannot be switched synchronously by switching different perspectives in the game, resulting in the user being unable to understand the relevant operations in the strategy in real time and intuitively, and the video teaching cannot provide users with a real-time and convenient experience.

[0067] The specific steps are as follows:

[0068] Step S100, obtaining the strategy screen perspective and the character perspective;

[0069] In this embodiment, the strategy screen is a screen that provides a detailed explanation of the game process, steps, and techniques. It is a strategy screen in the game scene corresponding to the character. The strategy screen is pre-made in the game, and the perspective of the strategy screen is the perspective of the strategy screen in the game scene corresponding to the character.

[0070] In this embodiment, the character perspective is the perspective of the character model controlled by the user in the game, wherein the game perspective of the character can be a first-person perspective or a third-person perspective.

[0071] The system obtains the character's perspective by receiving in real time the strategy screen display perspective and the character's game perspective sent by the game terminal, wherein the game terminal obtains the strategy screen display perspective and the character's game perspective after the character operated by the character enters the target scene, and sends the strategy screen display perspective and the character's game perspective to the system, wherein the character's perspective can be transformed by moving the mouse or by rotating the handle, and the strategy screen display perspective is the strategy screen display perspective within the level preset by the game terminal.

[0072] Specifically, the step S100 includes the following steps S110-S130:

[0073] Step S110, obtaining the current game screen of the character;

[0074] In this embodiment, the character's current game screen is the game screen after the character enters the game teaching level. The character's game screen is a scene screen. The scene screen is the scene screen in the current game. The scene screen includes, for example, a mountain model, a tree model, a stone model, etc., wherein the game screen can be a dynamic screen or a static screen.

[0075] The system obtains the character's game screen by receiving the character's game screen sent by the game terminal in real time, wherein the game terminal obtains the character's game screen after the character operated by the character enters the target scene, and sends the character's game screen to the system, wherein the target scene can be a scene where the character operated by the character enters a teaching level, or a scene where the character operated by the character enters a plot level.

[0076] In this embodiment, the game screen feature set is a set used to calculate the relevance similarity with the strategy screen, so that the system can determine the corresponding strategy screen under the game screen.

[0077] Step S120, determining the characteristics of the game screen;

[0078] Specifically, the step S120 includes the following steps S121-S123:

[0079] Step S121, extracting a trajectory curve in the game screen;

[0080] In this embodiment, the preset trajectory curve is used as a feature matching function of the game screen of the character, wherein the preset trajectory curve covers various parts of the screen and can reduce the amount of calculation at the same time. For example, the feature matching function of the game screen of the character is y 2 =x 3 +ax+b, where a and b are constants and can be adjusted, and (x, y) is any point on the preset trajectory curve of the game screen of the character.

[0081] Step S122, converting the point pixel value of the trajectory curve into a color intuitive model value;

[0082] In this embodiment, the point pixel value of the trajectory curve is the pixel value of any point on the trajectory curve, that is, the RGB value, and the color intuitive model value is the HSV value, wherein HSV respectively represents Hue, Saturation and Brightness. HSV further encapsulates the color information to express color changes (changes in hue, brightness, and color purity) in a form that is easier for humans to perceive.

[0083] Specifically, the process of converting the point pixel value of the trajectory curve into the color intuitive model value is:

[0084] max=max(R,G,B)

[0085] min = min(R, G, B)

[0086] V = max(R, G, B)

[0087] S=(max-min) / max

[0088] if(R=max)H=(GB) / (max-min)×60;

[0089] if(G=max)H=120+(BR) / (max-min)×60;

[0090] if(B=max)H=240+(RG) / (max-min)×60;

[0091] if(H<0)H=H and 360

[0092] Constructor-based The color intuitive model value of the point on the trajectory curve is calculated.

[0093] Step S123, obtaining the game screen features based on the trajectory curve and the color intuitive model value.

[0094] In this embodiment, the sample values ​​z1, z2, ... z of several sample pixel points on this curve are constructed. N , in the two-dimensional space composed of the curve x and the color intuitive model value z, the sample point data (x1, z1), (x2, z2), ... (x N , z N ), we get the game screen feature set A = {(x1, z1), (x2, z2), ... (x N , z N )}, refer to Figure 3 , is to draw a data curve based on the set A of game screen features.

[0095] Step S120, matching the features with strategy screens to determine matching strategy screens;

[0096] In this embodiment, the feature set is matched with the strategy screen by calculating the feature set of the character's current game screen through a preset association similarity model, finding a strategy picture with similar features from the strategy screen, and determining the final strategy screen.

[0097] Specifically, the step S120 includes the following steps S121-S123:

[0098] Step S121, obtaining features of the strategy screen;

[0099] In this embodiment, the feature set of the strategy screen is obtained in the same manner as in step S110 above, and the feature sets of all strategy screens are obtained, wherein there may be only one or more feature sets of the strategy screens.

[0100] Step S122, calculating the similarity between the features of the game screen and the features of the strategy screen;

[0101] In this embodiment, the system can calculate the current game screen feature set of the character through a preset association similarity model, find a strategy picture with similar features from the strategy screen, and determine the target strategy screen. Among them, there can be only one strategy screen for the game, or there can be several, that is, there can be only one teaching level in the game, or there can be several. Among them, if there is only one strategy screen for the game, the strategy screen can be determined as the final strategy screen. If there are several strategy screens for the game, the preset association similarity model is used to calculate the current game screen feature set of the character, and find a strategy picture with similar features from several strategy screens to determine the target strategy screen.

[0102] In this embodiment, the preset association similarity model calculates the feature similarity function of the game screen feature set and the screen feature set of all strategies:

[0103] H(A,B)=max(h(A,B),h(B,A))

[0104] Among them, set A is the strategy screen feature set, set B is the game screen feature set, and

[0105] h(A, B)=max(min(dist(a, b))), a∈A, b∈B

[0106] h(B,A)=max(min(dist(b,a))), a∈A, b∈B

[0107]

[0108] Among them, h(A, B) is the one-way similarity distance function from set A to set B, that is, h(A, B) actually first calculates each point a in point set A. i To the distance a from this point i The nearest point b in set B j The distance between ||a i -b j || sort them, and then take the maximum value of the distance as the value of h(A, B), and h(B, A) can be obtained similarly.

[0109] For example, refer to Figure 4 , let a={a1,a2},b={b1,b2,b3},the distances from point a1 to points b1,b2,b3 are d 11 , d 12 , d 13 , the distances from point a2 to points b1, b2, and b3 are d 21 , d 22 , d 23 ,and:

[0110] d 11 ≤d 13 ≤d 12 ,

[0111] d 23 ≤d 21 ≤d 22 ,

[0112] d 11 ≥d 23

[0113] First, take out the minimum value set from point a to point b, and then take the maximum value from the set, that is:

[0114] h(a, b) = d 11

[0115] By dividing the A and B sets into a preset number of segments, set to m, the similarity distance set is obtained by segment calculation in the above manner:

[0116] C = {d1, d2, ..d m}

[0117] Based on the similarity distance set, similarity probability results of a preset number of the strategy screens are calculated:

[0118]

[0119] Among them, C1, R are constants, and

[0120]

[0121] Step S123, determining a matching strategy screen according to the features of the strategy screens whose similarities are within a preset probability threshold range.

[0122] When the similarity probability result of the strategy screen is α≤ρ≤1, that is, the comparison result of the similarity probability result is within the preset probability threshold, the target strategy screen is obtained.

[0123] In this embodiment, based on the game screen information of the character, the game strategy picture of the corresponding scene and the strategy screen of the associated perspective are matched, that is, the corresponding strategy screen in the game scene.

[0124] Step S140, determining the perspective of the strategy screen based on the matched strategy screen.

[0125] In this embodiment, the system determines the display perspective of the strategy screen in the game interface based on the strategy screen.

[0126] Before the step of obtaining the current game screen of the character and determining a game screen feature set based on the game screen in step S110, the method includes the following steps A100-A200:

[0127] Step A100, obtaining a sample of a game screen feature set;

[0128] In this embodiment, the system pre-acquires a sample of a game screen feature set, wherein the game screen is a fixed screen for each teaching level in the game, and the feature set of the fixed screen for each teaching level is used as a sample set.

[0129] Step A200, inputting the game screen feature set sample into the preset association similarity model to obtain a similarity probability result, and using the similarity probability result as a probability threshold.

[0130] In this embodiment, the system inputs the game screen feature set sample into the preset association similarity model, and based on the preset association similarity model, performs feature similarity function calculation on the game screen feature set sample and the corresponding strategy screen feature set to obtain a similarity probability result, and uses the similarity probability result as a probability threshold. For example, if the similarity probability between the teaching level 1 and its corresponding strategy screen is 96%, 96% is used as the probability threshold.

[0131] Step S300: adjusting the strategy screen based on the perspective change information.

[0132] In this embodiment, after determining the game perspective of the character, the target strategy screen is displayed in the screen of the character's game perspective. By switching different perspectives in the game and synchronously switching the angle of the teaching video, the user can understand the relevant operations in the strategy in real time and intuitively, thereby improving the character's experience in video teaching.

[0133] In step S300, before the step of adjusting the strategy screen to the direction of the character's perspective based on the perspective change information, the method includes the following steps B100-B200:

[0134] Step B100, determining a projection screen of the strategy screen in a vertical viewing angle in the game;

[0135] Step B200: obtaining a preset number of target images in different directions based on the projection image.

[0136] In this embodiment, refer to Figure 5 , synchronously prepare a preset number of target strategy screens in different directions, and the preset number of target strategy screens in different directions are vertical perspectives. For example, synchronously prepare four vertical perspectives of the target strategy screen, namely, front, back, left, and right. The back perspective of the character is used as the C perspective, the left perspective is used as the L perspective, the right perspective is used as the R perspective, and the front perspective is used as the D perspective.

[0137] In another embodiment, before the step S100 of obtaining the strategy screen perspective and the character perspective, the following steps C100-C200 are included:

[0138] Step C100, pre-processing all the strategy screens to determine the vertical viewing angles of all the strategy screens in the game;

[0139] Step C200, based on the total strategy screens of the vertical viewing angle, obtain a preset number of the total strategy screens of different directions.

[0140] In this embodiment, the system pre-synchronizes a preset number of all the strategy screens in different directions for all the strategy screens. For example, all the strategy screens are synchronously prepared in four vertical perspectives of front, back, left, and right, with the character's back perspective as the C screen, the left side screen as the L perspective screen, the right side as the R perspective screen, and the front screen as the D screen.

[0141] Specifically, the step S300 includes the following steps S310-S320:

[0142] Step S310, determining target screens in two orthogonal directions corresponding to the perspective change information, wherein the target screen is a projection of the strategy screen in the game at a vertical perspective, and the projection directions of the target screens are different;

[0143] In this embodiment, the initial game perspective is defined as the perspective of the character controlled by the character when it is stationary, which is convenient for obtaining the change of perspective. The character can change the perspective by moving the mouse or rotating the handle. Based on the difference between the initial game perspective and the game perspective of the character, the perspective change information is obtained, and the perspective change information includes the perspective rotation angle and rotation direction.

[0144] In this embodiment, based on the preset number of target images in different directions and the perspective change information, the target image in the game perspective direction of the character is obtained, referring to Figure 6 Based on the perspective change information, the target screen of the associated direction is determined, and the role-playing game perspective screen is simulated and generated. For example, referring to Figure 6 , the perspective change information is a 45-degree rotation angle in the southeast direction, then the target strategy screens in the associated direction are the D screen and the R screen, and the angle screen T is generated by quickly simulating the D screen and the associated R screen.

[0145] Reference Figure 7 The three-dimensional perspective, point a is the character's initial perspective, ab is the vector of the character observing the D screen from the front (ab is perpendicular to the D screen), ac is the vector of the character observing the R screen (ac is perpendicular to the R screen), when the character is in the ab direction, start rolling the mouse to adjust the direction perspective to ad (forming the perspective of the character observing the T screen, ad is perpendicular to the T screen). The strategy has been pre-processed, so you can directly get the strategy pictures of different directions associated with the target pictures of the recommended strategy, refer to Figure 8 , according to picture D, it is associated with picture R rotated 90° to the left, picture R rotated 90° to the right, and picture C rotated 180°.

[0146] Step S320, mapping the target image to a direction corresponding to the character's perspective.

[0147] Specifically, the step S320 includes the following steps S321-S322:

[0148] Step S321, determining the mapping position corresponding to each pixel point on the target image;

[0149] Specifically, the step S321 includes the following steps:

[0150] In this embodiment, refer to Fig. 9 When the character's perspective changes, the trajectory formed is the trajectory formed by the following circle, and the rotating perspective screen forms a section on the circle. Then the character's current screen T is the projection of the oe+of part in the D screen on the ef screen, where: o is the intersection point of the D screen and the R screen; b is the vertical point of the D screen in front of the character, and it is also the tangent point of the trajectory circle; c is the vertical point of the R screen in front of the character, and it is also the tangent point of the trajectory circle; ef is the T screen plane formed when the character moves the character; d is the vertical point of the T screen in front of the character, and it is also the tangent point of the trajectory circle. According to the pictures in two orthogonal directions, the character direction perspective screen model is dynamically generated. Taking line calculation as an example: move any position (0, y on the ob line) i ), the corresponding pixel value is (r i ,g i ,b i ), the position of ob is a fixed value (0, b0), then at this time (x i ,y i ) is mapped onto the ef line (x' i ,y' i ), then when ab rotates to ad, the angle is θ, and the position relationship function of the two points is:

[0151]

[0152]

[0153] Among them, (x i ,y i ) is any pixel point on the target image, (x' i ,y' i ) is (x i ,y i ), (0, b0) is a fixed position of one target image, and (c0, 0) is a fixed position of another target image. Step S322, based on a preset mapping relationship between pixel points and pixel values, determining the pixel value of each pixel point at the mapping position;

[0154] Step S323: obtaining a mapping in a direction corresponding to the character's perspective based on the pixel value.

[0155] In this embodiment, the pixel (r, g, b) at any (x, y) of the D screen is stored in a computer storage mapping set map object (the mapping relationship is (x, y) -> (r, g, b)), then the RGB value of the pixel point at the corresponding position in the T screen can be calculated based on any point. Through this proposal, the character operates the mouse or handle to generate the target strategy T screen pixel value in real time.

That is, in the present application, after determining the strategy screen perspective and the character perspective, the strategy screen is displayed in the screen of the character perspective, that is, by switching the different perspectives of the character in the game and synchronously switching the angle of the teaching video, the user can understand the relevant operations in the strategy in real time and intuitively, and improve the character's experience in strategy teaching.
