(2) In single training, under the condition of using whole body tracking action capture, acquiring limb action information of a training person, acquiring action specification of the training person when the training person interacts with the virtual character, and acquiring information such as interactive voice of the training person and the virtual character, holding the posture of the police, pointing the police, using actions by the police, whether to strike or kill the virtual character by the limb and the like.
(3) In the multi-person training, under the condition that whole body tracking motion capture is not used, the station of each trained person is acquired, the multi-person cooperation is standardized, whether a firearm points to teammates, voice interaction is performed with virtual characters, cooperation is standardized when the virtual characters are uniformed, and information such as whether police are used for striking or killing the virtual characters is acquired.
(4) In the multi-person training, under the condition of capturing the whole body tracking action, the relative position information of the trained personnel is acquired, the multi-person cooperates with the formation, gestures used by the multi-person in cooperation, limb actions of the multi-person in cooperation, voices interacted with the virtual figures, the use condition of the firearm, whether the firearm points to teammates, the posture of holding the police, the use action of the police, whether the police is used for striking or killing the virtual figures, and the like are used.
After the data are collected, training data of each training person are generated, and the training data and training times are transmitted to a database for storage.
Wherein, the keywords of the interactive voice are obtained by using the voice recognition or other voice recognition tools of the Windows system. And obtaining the use parameters of VR input devices such as a VR handle, a VR position locator and the like, such as a handle trigger position, a handle orientation, a handle key state and the like, by using the corresponding VR SDK or developer authority.
In order to ensure training effect and training real experience, a training environment can be built in a real environment, if whole body tracking motion capture is needed, a positioning tracker is built, and some devices needed for training are placed on a planned training site according to a training scenario.
In step S103, the collected training data is analyzed and processed to obtain abnormal data reflecting abnormal behaviors of the trained personnel, which specifically includes:
before the training personnel starts training, accessing training data in a database, acquiring the training times of the training personnel, if the training times are greater than a preset threshold value, analyzing and processing the acquired training data to acquire abnormal data reflecting the abnormal behaviors of the training personnel, and continuously executing step S104. The preset threshold value can be calculated by using an AI algorithm, can be set as an adjustable variable, can be modified manually at the outside, or can be defined as a constant.
Analyzing and processing the acquired training data to obtain abnormal data reflecting the abnormal behaviors of the trained personnel, wherein the method specifically comprises the following steps: and (3) comparing the training data in the database piece by piece, removing repeated correct operation, carrying out sampling analysis on the abnormal operation (namely error operation) of the training personnel, analyzing the data piece by piece, and comparing the abnormal data of the multiple operation errors of the training personnel.
Optionally, in the analysis processing of the collected training data, the data comparison may be performed by using big data processing analysis to perform a certain AI calculation.

In step S104, the virtual character behavior adjustment data includes:
character data characterizing characters of the virtual character;
weight data characterizing the probability of virtual character behavior.
In step S104, virtual character behavior adjustment data for adjusting the behavior of the virtual character is generated from the anomaly data, specifically:
after obtaining the abnormal data reflecting the abnormal behaviors of the parametrics, generating new character data representing the character of the virtual character according to the abnormal data and the initial definition of the training script, inputting the character data and the abnormal data into a weight system, generating new weight data representing the probability of the behavior of the virtual character according to the character data and the abnormal data by the weight system, and writing the character data and the weight data into a configuration file.
When training of a training person starts, a configuration file is read, character data are input into an animation controller and a voice controller, after the animation controller receives the character data, a weighting system is called to access weight data in the configuration file, the weighting system returns action weights and voice action weights, the animation controller calls a action method from a action method set according to the action weights returned by the weighting system to control action behaviors of coordinated virtual characters, the voice controller calls the action method from the action method set according to the voice action weights returned by the weighting system to control the voice actions of coordinated virtual characters, so that new virtual character behaviors are obtained, the training starts is informed, and the training person starts new training.
For example: when the participant interacts with the virtual character, the participant extracts the voice keywords, which relate to the voice keywords such as the virtual character, the guide words which are unfavorable for solving the training event, and the like. The abnormal data obtained by analyzing and processing the training data comprises voice data reflecting the frightened virtual character, guide words for solving the adverse training event and the like, virtual character behavior adjustment data for adjusting the behavior of the virtual character is generated according to the abnormal data and is written into a configuration file, after a training person starts new training and reading the configuration file, character characters of the generated virtual character are biased to the violent character, action behaviors are biased to the action of bias, the voice behaviors are biased to the interaction voice of bias so as to induce the training person to expose more error operations, and weak items of the training person can be reflected in time.
