Problems solved by technology

[0004] However, in this existing anti-cheating technology, the functions of preventing cheating and detecting cheating need to be deployed on the client side, so that cheating developers can easily debug the anti-cheating components locally and formulate targeted bypass strategies
Furthermore, it is difficult to detect the user's cheating behavior

Embodiment approach A

[0052] Embodiment A: Detect the aiming path based on the change of the viewing angle.

[0053] In the FPS game, the game player shoots and aims through the subjective perspective of the virtual game character. Therefore, the perspective of the game character is the aiming perspective. Based on this, optionally, for the t-th frame of images among the consecutive multiple frames of images, a target ray may be emitted in this image with the aiming viewpoint of the game character as an endpoint, so as to determine the aiming direction. Wherein, the aiming viewpoint may be the position of the eyes of the game character, the position of the muzzle of the virtual prop used by the game character, or the position of the front sight on the virtual prop gun, etc. This embodiment includes but is not limited thereto.

[0054] Next, the angles between the target ray and the horizontal plane and the vertical plane can be calculated respectively to obtain the first angle offset value x t and...

Embodiment approach B

[0056] Embodiment B: Detect the aiming path based on the change of the sight point.

[0057] In this embodiment, for any frame of image, a target ray is emitted with the aiming point of the game character as an endpoint, and based on the image, an intersection point where the target ray intersects with an object in the game world is determined. Next, calculate the coordinates of the intersection point in the game world as the user's aiming coordinates in the image.

[0058] After the aiming coordinates corresponding to each of the consecutive multiple frames of images are acquired, an aiming path corresponding to the virtual shooting operation may be generated based on the plurality of aiming coordinates. An exemplary description will be given below in conjunction with Embodiment A.

[0059] In some optional embodiments, a coordinate sequence formed by a plurality of aiming coordinates may be used as an aiming path of a shooting operation. For example, the aiming path can be...

Abstract

The embodiment of the invention provides a cheating detection and model training method and device for a shooting game and a storage medium. After a server obtains video data of a shooting game, aiming paths of virtual shooting operation of a user in the shooting game are detected based on the video data, the aiming paths are classified according to the neural network model, and a cheating detection result of the virtual shooting operation is obtained. According to the implementation mode, deployment on the server side is easy, an anti-cheating program does not need to be deployed on a game terminal, and therefore the cheating detection strategy is not likely to be bypassed by a cheating user in a targeted mode. Meanwhile, depending on the strong learning and computing capabilities of the neural network model, whether the virtual shooting operation is a cheating behavior or not can be accurately recognized based on the aiming paths, and the accuracy and reliability of the cheating detection method are greatly improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a cheating detection, model training method, device and storage medium of a shooting game. Background technique [0002] In a first-person shooting game (First-person shooting game, FPS), some users cheat through plug-in programs. For example, quickly locate the enemy's position through the plug-in program, quickly target the enemy through the plug-in program, etc. These cheating behaviors undermine the fairness and fun of the game, resulting in the loss of a large number of users. [0003] At present, there are some client-based FPS game anti-cheat detection methods, which mainly prevent cheating programs from accessing the game by installing a kernel or upper-level anti-cheat components on the game client, and collect and report the cheating codes to realize the detection of cheating users. banned. [0004] However, in this existing anti-cheating technolog...
