[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] It should be noted that the terms "first," "second," "third," "fourth," etc. in the description and claims of the present invention are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having," as well as any variations thereof, in the embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0055] At present, in the confrontation training and exercises of the troops, the purpose of training is generally achieved by using live ammunition and aerial targets. The disadvantages of this method are high cost, limited venues, high requirements for conditions, and difficult maintenance. For this reason, it is necessary to develop a simulated confrontation training system that uses a virtual environment to simulate actual combat situations to achieve the purpose of training and exercises. However, the current virtual environment can only provide some simple interactive content and cannot achieve a better simulation of the environmental state; and then restore the real scene state. Based on this, the embodiment of the present invention discloses a shooting simulation training method, device, electronic device and storage medium based on a motion vehicle, which realizes the motion state simulation in multiple scenarios by setting the motion vehicle on a vibration platform. By adopting a real vibration platform, the overall simulation training can be more in line with the actual situation, and can more realistically reflect the actual state, thereby improving the training simulation effect.

[0056] Example 1

[0057] See also Figure 1 , Figure 1 It is a flow chart of the shooting simulation training method based on a sports vehicle disclosed in an embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software and / or hardware, and the execution subject can receive relevant information by wired or / and wireless means, and can send certain instructions. Of course, it can also have certain processing functions and storage functions. The execution subject can control multiple devices, such as a remote physical server or cloud server and related software, or it can be a local host or server and related software that performs related operations on a device placed somewhere. In some scenarios, multiple storage devices can also be controlled, and the storage devices can be placed in the same place or different places as the devices. For example Figure 1and Figure 4 As shown, the shooting simulation training method based on the sports vehicle includes the following steps:

[0058] S101: receiving training subjects, training conditions, and trainees configured by the instructor;

[0059] S102: issuing a corresponding training task, generating a training task scenario based on the training task, and associating data between the training task scenario and a training terminal of a corresponding trainee; the training terminal includes a motion vehicle and a vibration platform, and the motion vehicle is disposed on the vibration platform;

[0060] Before training begins, the instructor must configure various parameters, such as the number of trainees and the training subjects. Only after these configurations are complete can trainees proceed with subsequent simulation training. Different training processes are employed for different training subjects. In this embodiment of the present invention, the vehicle can typically be an assault vehicle or a marine boat. Assault vehicles typically navigate relatively rugged mountain roads, and marine boats traveling on the sea surface also generate certain fluctuations. This fluctuation significantly increases the difficulty of aiming, as the resulting vibrations after actual aiming can cause significant deviations in the final missile trajectory. Therefore, it is necessary to simulate the actual flight trajectory to account for these vibrations.

[0061] The simulation cabin is primarily used for independent training and simulated assessment of gunners' shooting skills. It consists of a cabin, chassis, semi-physical simulation components, a physical control panel, and a switch panel. Integrating the actual layout and product universality requirements, the cabin adopts a semi-enclosed box-like structure, with the front, left side, top, and bottom sections fully enclosed, while the right side and rear sections are open. Furthermore, to enhance the structure and facilitate lifting, the entire cabin adopts a frame-like design. The simulation cabin includes semi-physical simulation components such as the fire control computer, control panel, sight, thermal imager, elevation and deflection gear, steering gear, hydraulic booster rotary valve, and manual / automatic hydraulic system switch handle. The internal sight displays a three-dimensional simulated training scene. A six-degree-of-freedom vibration platform, controlled by the training control computer, simulates the vehicle's pitch, pitch, and other posture changes during firing in real time, creating a realistic shooting environment for trainees that resembles actual combat.

[0062] More preferably, after issuing the corresponding training task, generating a training task scenario based on the training task, and associating data between the training task scenario and the training terminal of the corresponding trainee, the method further includes:

[0063] The sound module at the vehicle is used to play a sound to distinguish the current state of the vehicle; if the corresponding sound is heard and the corresponding command trigger is detected, the next step is executed;

[0064] The training task includes training terrain, training time period and training weather. The training terrain includes sea, beach, mountain and jungle. The training weather includes sunny, cloudy, rainy, snowy and foggy days. The training time period includes early morning, noon, evening and night. The generating of the training task scenario based on the training task includes:

[0065] Initializing the three-dimensional simulation scene based on the training task, and controlling the training terminal to load into a working state based on the training task;

[0066] Generating corresponding three-dimensional scene data based on the training terrain, training period and training weather;

[0067] The three-dimensional scene data is transmitted to the projector through the fusion device, and the three-dimensional scene data is projected onto the front screen by the projector for display.

[0068] By using three-dimensional scene data for projection display, users can know what scene they are currently in.

[0069] S103: Calling corresponding vibration data based on the training task scenario, and sending the vibration data to the vibration platform through the network device and the vibration control cabinet to perform training simulation;

[0070] Generally, the above trajectory deviation can be simulated by using simulation software, which can achieve a certain actual simulation effect. However, this method has a disadvantage that it is impossible for the operator to actually perceive it. The operator can only perceive it by reading information, which brings a great challenge to the actual simulation of the user. Therefore, in an embodiment of the present invention, a six-axis vibration platform is used to simulate the different motion states of the moving vehicle thereon. This simulation has more advantages than the simulation of simple software. On the one hand, it can provide trainees with a more realistic environmental motion state simulation, and on the other hand, it can assist in calculating the flight trajectory of each motion trajectory. This method allows users to be in a more realistic simulation environment. They can not only capture information through their eyes, but also feel the increase in shooting aiming brought by the real environment through vibrations in various aspects. The vibration platform allows users to not only consider the aiming at the final shot, but also how to aim at the angle during the vibration process, thereby helping users improve their actual combat experience.

[0071] During specific implementation, there are different vibration data for different application scenarios. For example, the vibration amplitude and feeling are completely different for different environments such as the sea and mountain roads. Therefore, different vibration data can be set based on different training scenarios. During more specific implementation, a variety of vibration parameters can be set for different scenarios. For example, 10 different parameters can be set for the sea scene and 10 different parameters can be set for the mountain road scene. In this way, during specific implementation, it is only necessary to randomly select a parameter in a specific scenario. This setting method is mainly to prevent the situation where effective simulation cannot be achieved after becoming particularly familiar with the regular vibration in a certain environment.

[0072] S104: receiving simulated weapon operation information of a user based on a motion vehicle, and performing shooting simulation training based on the simulated weapon operation information to obtain simulation parameter information; wherein the motion vehicle is disposed on the vibration platform, and the vibration platform is used to simulate various pitch angles, tilt angles, vertical lift heights, and rotation angles during the motion of the motion vehicle;

[0073] S105: Get simulation results based on the simulation parameter information. More preferably, Figure 2 This is a flow chart of obtaining training simulation parameters disclosed in an embodiment of the present invention. Figure 2 As shown, the receiving of the user's simulated weapon operation information based on the sports vehicle, and performing shooting simulation training based on the simulated weapon operation information to obtain simulation parameter information, includes:

[0074] S1041: receiving a launch control instruction from a user based on a weapon control component of a sports vehicle; if the launch control instruction matches a preset logic, executing the next step; if not, prompting the user;

[0075] S1042: Matching corresponding projectile simulation information based on the weapon type in the sent control instruction, and performing ballistic flight simulation according to the projectile trajectory information and current target aiming information;

[0076] S1043: Determine final hit parameters based on the ballistic flight simulation.

[0077] In practice, different motion platforms have different sets of operating instructions. Only when all instructions are correctly executed can subsequent launch commands be executed; if the instructions are incorrect, subsequent launch operations cannot be performed. Once the user determines the launch angle and direction, they can control the simulated missile launch to simulate the impact state. After the user clicks launch, the movement direction of the vibration platform is recorded, and this movement direction is then fitted with the simulated trajectory of the virtual projectile to obtain a more accurate flight trajectory, resulting in a more effective simulation.

[0078] More preferably, Figure 3 FIG. 1 is a flow chart of a virtual projectile simulation process disclosed in an embodiment of the present invention, such as Figure 3 As shown, the ballistic flight simulation is performed according to the projectile trajectory information and the current target aiming information, including:

[0079] S10421: Obtaining first coordinate information of the corresponding laser point on the display screen;

[0080] S10422: Creating a virtual aiming line for the trainee based on the first coordinate information and a coordinate conversion relationship between the screen coordinate system and the three-dimensional coordinate system;

[0081] S10423: Create initial random scatter parameters for projectiles based on the correspondence between the sight and the firing angle in the preset firing table;

[0082] S10424: Controlling the virtual flight trajectory of the projectile according to the virtual aiming line, the initial random scattering parameters, and the projectile fitting model based on the preset firing table, so that the ballistic characteristics of the virtual projectile are consistent with the ballistic characteristics in the preset firing table, thereby realizing ballistic flight simulation.

[0083] The above is the specific implementation logic for virtual projectile trajectory simulation. Once the aiming line and initial random scatter parameters are determined, the virtual projectile's flight trajectory and final impact position can be realized. The ballistic characteristics of the flight trajectory here are consistent with those in the firing table, enabling accurate trajectory simulation.

[0084] More preferably, the method of creating the initial random scattering parameters of the projectile based on the correspondence between the rear sight and the shooting angle in the preset shooting table includes:

[0085] Construct a projectile dispersion function based on the projectile dispersion parameters in the preset shooting table;

[0086] When creating a virtual projectile according to the user's sight parameters and the projectile dispersion function, the initial distribution parameters of the virtual projectile are given by setting the random variation range of the initial shooting angle.

[0087] More preferably, determining the final hit parameters based on the ballistic flight simulation includes:

[0088] When a collision between a virtual projectile and a terrain, object or target in a virtual environment is detected, collision interaction information between the virtual projectile and the virtual environment is obtained according to a virtual collision principle;

[0089] The damage results of the projectile on the target, terrain or ground objects are evaluated according to the collision interaction information and the damage assessment model in the three-dimensional simulation software to obtain corresponding damage parameters and target hit information; and simulation is performed based on the damage parameters and target hit information.

[0090] In practice, after the projectile contacts the corresponding target at different angles and hitting points, the damage state is also different. The damage state can be determined based on the angle and distribution parameters, and the damage state can be actually displayed in the projection. In addition, when performing specific implementation, the performance can be determined based on the hit data.

[0091] More preferably, the acquisition box interface data of the moving vehicle is serial port output data, and the acquisition box interface data includes frame header and frame footer, magnification conversion data, ranging button data, firing button data, shooting data, height switch data, thermal imaging switch data, narrow viewing distance switch data, wide viewing distance switch data, polarity data, height and low direction data, horizontal direction data, contrast data, brightness division data, dynamic and static switch data, azimuth switch data, power switch data, display switch data, turret handle position data, height and low firing button data, direction firing button data, conversion handle position data, and steering machine data;

[0092] The fire control computer interface data of the mobile vehicle is serial port output data, and the fire control computer interface data includes frame header and frame footer, power switch data, day and night switch data, correction button data, combat button data, level sensor data, laser rangefinder data, night vision data, automatic gun adjustment data, strobe distance data, height data, azimuth data, setting button data, test button data, reset button data, emergency button data, tilt sensor data and manual distance data;

[0093] The display box interface data of the sports vehicle is serial port output data;

[0094] The vibration data is input as 64-bit data using the UDP protocol. This data includes a header and checksum, side displacement, longitudinal displacement, lift, pitch angle, roll angle, yaw angle, amplitude, velocity, and compliance. The specific protocol control for the vibration platform is shown in the figure.

[0095] The embodiment of the present invention mainly includes the following simulation modules:

[0096] Weapon trajectory simulation: The basic process of VMS platform trajectory simulation is as follows:

[0097] First, trigger image retrieval

[0098] The training and control computer image recognition module receives continuous images of the simulated scene from the recognition camera in real time, and retrieves the scene images of each simulated weapon firing moment in real time (images of newly added laser points appearing, which can be single laser points or multiple laser points, and images of each newly added laser point appearing need to be retrieved in real time).

[0099] Second, aiming point coordinate calculation

[0100] After retrieving the scene image at the moment of firing, the training and control computer image recognition module calculates the screen coordinate data of the laser point on the projection screen at the moment of firing through a scaling algorithm based on the proportional relationship between the camera resolution and the projection scene resolution.

[0101] Then, based on the software calibration data during the reference system calibration (correction data for the deviation between the aiming point of each gun and the laser point at the calibration distance), the coordinates of the trainee's aiming point on the screen are finally determined.

[0102] Third, coordinate system conversion

[0103] The VMS platform's "ScreenToWorldPoint" function automatically generates a mapping point for the on-screen aiming point in the virtual scene. This mapping point automatically determines the coordinates of the aiming point in the virtual scene (the coordinates of the aiming point on the virtual terrain, target, or other simulated entities, such as buildings and fortifications, are the same as those observed by the trainee on the screen).

[0104] Fourth, establish a virtual line of sight

[0105] After the aiming point mapping is completed, the platform automatically establishes a virtual aiming line.

[0106] The virtual aiming line is the line connecting the virtual scene camera (the camera's position is determined during the lesson design and varies depending on the shooting posture. When the subject's posture changes during training, the camera's position also changes) and the mapping point. This line can be considered a virtual aiming line.

[0107] Fifth, create the projectile

[0108] After determining the virtual aiming line, the system automatically creates a virtual projectile in the center of the camera's field of view.

[0109] 6. Virtual Flight and Collision Detection

[0110] After creating a projectile, the platform, supported by a ballistic simulation model, controls its flight toward the target. During the projectile's flight, the system automatically and accurately simulates the projectile's dispersion parameters (the angular dispersion of the projectile's flight direction relative to the barrel axis), flight speed variations, trajectory altitude variations, and environmental influences. It also performs real-time collision detection. Upon collision with a target or other simulated entity, the system outputs the hit result in real time, displaying the impact.

[0111] The visual simulation subsystem in the embodiment of the present invention mainly relies on the VMS platform to realize the simulation of the battlefield environment, provide virtual battlefield environment simulation images for shooting training, simulate the behavior of combat objects (enemies / targets), and provide a real training environment, including vision, sound, etc.

[0112] It provides geographical environment simulation function, and the three-dimensional terrain is consistent with the actual terrain coordinates.

[0113] It provides meteorological environment simulation function, which can simulate cloudy, sunny, rainy, snowy, foggy, temperature, wind and other meteorological conditions, and its impact on the trajectory is consistent with the actual situation.

[0114] It provides weather environment simulation function, which can simulate weather environments such as early morning, noon, evening, night, and four seasons.

[0115] It provides combat action simulation functions, can simulate various enemy targets, and the appearance characteristics of enemy targets are consistent with reality; enemy combat actions are consistent with enemy action rules; it provides target damage simulation, and the strike effect is consistent with the actual situation.

[0116] The training scene presentation subsystem is mainly composed of battlefield terrain simulation, weather condition simulation, lighting condition simulation, battlefield target simulation (including target combat action simulation), battlefield atmosphere generation, etc.

[0117] First, battlefield terrain simulation

[0118] We generate 3D scenes based on customer-provided military data maps of the training area, or digital maps obtained from publicly available terrain data sources. High-fidelity 3D terrain modeling consists of four steps: data processing, landform construction, terrain model preparation, and terrain configuration.

[0119] Second, data processing

[0120] Data processing mainly involves data acquisition, coordinate conversion, area clipping, data correction and other operations for digital elevation data, remote sensing image maps and vector terrain data, in order to prepare data for subsequent steps.

[0121] Third, landform modeling

[0122] Based on the processed digital ground elevation model, remote sensing image data and mask map, a three-dimensional terrain model that can display the ground undulation characteristics and surface texture is generated according to the steps of setting the regional scope, adjusting the elevation data resolution, and modulating the surface texture.

[0123] Third, prepare the terrain model

[0124] According to system requirements, the required models of settlements, vegetation, roads, etc. in the simulated terrain are sorted out and obtained, and integrated into the terrain model library.

[0125] Fourth, land feature configuration

[0126] On the basis of completing the landform modeling, the land feature configuration is completed according to the vector terrain data, which is generally implemented in the steps of configuring residential areas, roads, water systems, and vegetation.

[0127] The VMS simulation platform in the embodiment of the present invention has a meteorological environment module, which can not only centrally store and process meteorological simulation data information, but also simulate and generate meteorological information at a certain time and point in time in real time. It can also set meteorological changes such as cloudy, clear, rainy, and snowy in the virtual battlefield environment, and can set the changes in rainfall, cloudy days, and snowy days and store them in the database.

[0128] First, lighting condition simulation

[0129] The VMS simulation platform has a lighting condition simulation module that can simulate lighting conditions such as daytime, nighttime, strong light, and weak light.

[0130] Second, battlefield target simulation

[0131] A) Accurate target modeling

[0132] According to the needs of battlefield enemy situation construction, various targets are simulated. High-fidelity 3D simulation models of targets are constructed, including high-poly, low-poly and P3D models.

[0133] B) Dynamically generate scene targets

[0134] After the target model resources are built, they are configured and stored in the model resource library for dynamic calling by the training system.

[0135] Third, battlefield atmosphere simulation

[0136] In response to the needs of simulation training, a simulation of battlefield combat scenes is constructed, and the CGF subsystem is called to generate a mode for automatic engagement of simulated force intelligent agents to provide combat scenes to trainees.

[0137] In the embodiment of the present invention, the shooting simulation training method based on the motion vehicle realizes motion state simulation in multiple scenarios by placing the motion vehicle on a vibration platform. By adopting a real vibration platform, the overall simulation training can be more in line with the actual situation, can more realistically reflect the actual state, and improve the training simulation effect.
