Description

METHOD IN A COMBAT VEHICLE FOR TARGET TRACKING TRAINING OF COMBAT VEHICLE WEAPON SYSTEM INCORPORATED, COMPUTER-READABLE STORAGE MEDIUM AND ELECTRONIC DEVICE PROVIDED WITHIN A COMBAT VEHICLE TECHNICAL FIELD

[001] The present invention relates to a method for training target tracking of a combat vehicle weapon system embedded in accordance with the preamble of claim 1. The present invention also relates to an electronic device and a computer-readable storage medium for carrying out the method. PREVIOUS TECHNIQUE

[002] Currently, there are numerous examples of training systems for training operators of various combat vehicle weapon systems, such as armored vehicles, tanks, and infantry fighting vehicles.

[003] One type of training system for training target tracking of a combat vehicle is based on the use of one or more physical targets, such as target cards or redefinable target points. However, such training systems require external facilities that consume space in a controlled training environment.

[004] Another form of training systems are live training systems, such as laser-based training systems, in which vehicles are equipped with laser transmitters and receivers to allow the simulation of firing events via the transmitters and the detection of hit events via the receivers. Although these types of training systems provide effective means for training crew members Petition 870250092629, dated 10 / 10 / 2025, page 11 / 108 At 2 / 42 of the size of a combat vehicle, they also have a high cost, as relatively complex equipment needs to be installed on various objects, such as vehicles. Furthermore, to practice moving target tracking, more than one vehicle needs to be included in the training, so the training cost is relatively high due to fuel consumption and the increased number of crew members.

[005] Yet another form of training system is combat vehicle simulators where, for example, a desktop computer is used to simulate a vehicle, its weapons systems, and targets in an environment surrounding the vehicle. This type of training system can also be provided within a prototype vehicle. However, while the use of a desktop computer can provide economical training, the degree of realism will be limited. Furthermore, the use of a prototype vehicle for training requires a complex and costly installation.

[006] Therefore, there is a need for improvements within target tracking training systems, for example, to improve the training of combat vehicle gunners. OBJECTIVES OF THE INVENTION

[007] One objective of the present invention is to provide a more effective method for target tracking training of combat vehicle weapons.

[008] An additional objective of the present invention is to provide a method for training target tracking of combat vehicle weapons that is simple and economical.

[009] An additional objective of the present invention is to provide a method for training combat vehicle weapon target tracking with improved availability, avoiding the need for complex and high-cost training facilities. Petition 870250092629, dated 10 / 10 / 2025, page 12 / 108 3 / 42 SUMMARY OF THE INVENTION

[0010] These and other objectives, evident from the following description, are achieved by a method for training embedded combat vehicle weapon target tracking, a computer-readable storage medium, and an electronic device, as presented in the appended independent claims. Preferred embodiments of the method are defined in the appended dependent claims.

[0011] According to the invention, the objectives are achieved by a method in a combat vehicle for target tracking of an embedded combat vehicle weapon system that is performed in the combat vehicle. The combat vehicle comprises an electronic device with a video device and input means. The method is performed in said electronic device with a video device and input means. The method comprises: determining a trajectory of a virtual target over a period of time; determining a point-of-sight location of the combat vehicle weapon system based on a current aiming direction of the weapon along an azimuth and an elevation direction.The method further comprises obtaining a sequence of images from a camera with a sight associated with the combat vehicle's weapon system; displaying, on the video device: said sequence of images; a first graphic object, superimposed on the sequence of images, wherein the first graphic object is representative of the location of the aiming point and displayed in a first position on the video device to indicate the determined location of the weapon system's aiming point; and a second graphic object, superimposed on the sequence of images, wherein the second graphic object is representative of the virtual target and displayed in a second position on the video device to indicate an initial position of the virtual target based on the trajectory determined over the period. Petition 870250092629, dated 10 / 10 / 2025, page 13 / 108 4 / 42 of time; when displaying the graphic objects on the video device: update the display of the second graphic objects by moving the second graphic object from the second position along the determined trajectory during the time period; and receive, through the input means, one or more user inputs representing one or more control signals that cause the movement of the aiming direction of the weapon system along the azimuth and / or elevation direction; in response to receiving one or more user inputs, update the display of the first graphic object by moving the first graphic object from the first position according to the movement of the weapon's aiming direction caused by one or more user inputs.

[0012] Through this, an effective method is achieved for providing target tracking training to an operator of a weapon system (e.g., a gunner operating a main gun) integrated into a vehicle, wherein the training can be carried out effectively with a relatively high degree of realism and at a low cost, since a real combat vehicle can be used for the training, i.e., the training is incorporated, without the need for any physical targets (e.g., another physical target installation external to the vehicle or another vehicle acting as a target). Thus, the crew (e.g., one or more members of a combat vehicle crew, such as a gunner) can position themselves inside the combat vehicle in their respective operating posts while performing training that provides a greater degree of realism.Furthermore, target tracking training can be performed while the combat vehicle remains stationary or while the combat vehicle is in motion.

[0013] According to one embodiment of the method, the method also comprises, when displaying the graphical objects: determining, over the period of time, the metrics associated with when the first object Petition 870250092629, dated 10 / 10 / 2025, page 14 / 108 5 / 42 The graphic object is within a limiting distance of the second graphic object, so as to allow evaluation of the aiming accuracy (e.g., target tracking performance, such as target tracking performance over time or responsiveness).

[0014] According to the invention, the objectives are also achieved by an electronic device that executes the method and by a computer-readable medium that stores one or more programs, one or more programs comprising instructions, which, when executed by an electronic device, cause the device to execute the method.

DETAILED DESCRIPTION

[0016] Below, Figure 1A provides a description of an exemplary electronic device for performing the techniques for embedded target tracking training. Figure 1B illustrates the weapon systems associated with the electronic device in Figure 1A. Figures 2A-2C illustrate an exemplary combat vehicle in which the electronic device can be incorporated to provide embedded target tracking training. Figures 3A-3D illustrate exemplary user interfaces displayed on a video device of an electronic device for providing embedded target tracking training, and Figures 4A-4B are flow diagrams that Petition 870250092629, dated 10 / 10 / 2025, page 16 / 108 Figures 7 / 42 illustrate methods for providing embedded target tracking training.

[0017] Figure 1A is a block diagram that schematically illustrates an electronic device 10, used to provide embedded target tracking training, as described in greater detail in relation to Figures 3A-3D and 4A-4B, according to the embodiments. Figure 1B illustrates the weapon systems associated with the electronic device illustrated in Figure 1A, particularly exemplifying the acquisition of an image sequence.

[0018] The electronic device is arranged to be incorporated into a combat vehicle, such as the combat vehicle illustrated in greater detail in relation to Figures 2A-2C. The electronic device may be incorporated into the combat vehicle by being provided within (e.g., mounted within an internal compartment) of the combat vehicle. In addition, the electronic device is configured to be coupled to an interface of one or more vehicle systems of the combat vehicle, such as the vehicle system 50 including one or more weapon systems 55 and associated weapon control systems (WCS) 58, including one or more sensors 58A, 58B and respective input means 59 to provide one or more control signals for the control of the weapon system (e.g., enabling an operator, such as a gunner, to control the weapon).

[0019] According to one embodiment, the electronic device can also be coupled to other vehicle systems 60, such as a drive control system 70 and sensor systems. This allows the electronic device to receive data from vehicle systems, such as data associated with sensor data from the vehicle systems and data associated with user inputs provided to the vehicle systems. The sensor data may include representative data of a weapon system's aiming direction. Petition 870250092629, dated 10 / 10 / 2025, page 17 / 108 8 / 42 of the vehicle and / or one or more user inputs in the form of control signals provided by a user, such as a crew member (e.g., a gunner) controlling the aiming direction of the weapon system (e.g., the main gun of the combat vehicle).

[0020] According to one embodiment, control signals provided by a combat vehicle operator, entered through input device 59 (e.g., by the combat vehicle gunner using a sight or weapon system control handle) of weapon system 55, are received by the electronic device but are prevented from being transmitted to the weapon control system 58 to cause actual movement of the weapon system, including turret movements. In this embodiment, the control signals are used by the electronic device to enable the determination of a weapon system aiming direction, as described in greater detail below. A respective combat vehicle operator can override the locking functionality at any time, such as by means of a physical switch or button provided on the electronic device or weapon control system.This allows training to be performed while the weapon system remains stationary, but while the movements of the weapon system controlled by the weapon system operator are reflected by being determined by the electronic device (e.g., determined and displayed during training by means of a training motor module that is stored in the electronic device's memory). Enabling training while the weapon system remains stationary makes training easier in terms of meeting safety requirements for personnel and equipment in the vicinity of the combat vehicle.

[0021] The electronic device comprises one or more interfaces Petition 870250092629, dated 10 / 10 / 2025, page 18 / 108 9 / 42 communication interfaces, such as a communication interface 35, to allow the electronic device to be coupled to said vehicle systems. One or more communication interfaces, such as one or more communication interfaces comprising one or more communication ports, may, for example, provide one or more interfaces for coupling a communication line or bus 150, such as a CAN bus from the vehicle systems to the electronic device via a peripheral interface 25. The communication interface 35 may also comprise an Ethernet bus for communication of video and / or information signals, so as to allow the electronic device to obtain video signals, such as raw video signals from one or more camera devices (for example, a targeting camera of a respective weapon system).

[0022] According to one embodiment, the communication interface 35 may comprise an external port (not shown) for downloading data from the electronic device (e.g., data stored in memory) to an external device on the combat vehicle, for example, to allow evaluation or monitoring of the vehicle's external training.

[0023] Electronic device 10 also includes a power system (not shown) to power the various components of the electronic device.

[0024] The electronic device further comprises one or more processors 15, such as one or more central processing units (CPUs) or field-programmable gate arrays (FPGAs) or other suitable processing means and one or more memories 20 (which optionally include one or more computer-readable storage media). One or more processors are coupled to the memory via a memory controller 18 in such a way Petition 870250092629, dated 10 / 10 / 2025, page 19 / 108 10 / 42 to allow the execution of read and write operations.

[0025] The electronic device comprises a peripheral interface 25 used to couple input and output peripherals of the electronic device to the processor 15 and memory 20. One or more processors 15 execute various software programs and / or instruction sets stored in memory 20 to perform various functions for the device 100 and to process data, so as to allow the provision of embedded target tracking training. In some embodiments, the peripheral interface 25, the processor 15, and the memory controller 18 are optionally implemented on a single chip. In some other embodiments, they are optionally implemented on separate chips.

[0026] The electronic device comprises I / O (input / output) subsystems 30 that couple input / output peripherals, through the respective I / O subsystem controllers (not shown), to the electronic device. The input / output peripherals include a video device 40 and one or more input devices 45.

[0027] These components optionally communicate via one or more communication buses or signal lines 150.

[0028] Memory stores software components that include an operating system 22 and one or more programs that include a training engine module 24. The operating system includes various software components and / or drivers to control and manage general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

[0029] One or more input devices 45 may be a keyboard, a touch screen, a mouse, buttons or other suitable means of input that allow an operator to control various contacts. Petition 870250092629, dated 10 / 10 / 2025, p. 20 / 108 11 / 42 configurations of the training motor module 24. The various configurations of the training motor module 24 can also be controlled by means of buttons or a display, such as displayed buttons or hardware buttons associated with the display 40. Optionally, according to one embodiment, the inputs that allow controlling the various configurations can be provided by an operator using the input device 59 of the weapon control system. According to this embodiment, the input device 59 can replace the input device 45, so that the input device 45 of the electronic device is not required. The configurations may relate to the initiation (e.g., calling) of the training motor module, the start / end of training, the configuration of a user interface, such as the user interface illustrated in Figures 3A-3D provided by the training motor module and displayed on the video device.The configuration may also relate to the setting of one or more virtual targets and the selection or configuration of a simulated environment displayed on the video device. Settings according to a preferred embodiment also include one or more training difficulty settings that affect one or more settings associated with one or more virtual targets. The difficulty settings are described in greater detail below.

[0030] According to one embodiment, the training engine module 24 and its associated functionalities, including any additional modules, are configured as integrated into an existing electronic device in the combat vehicle, such as integrated into an electronic device as described above, but where the electronic device forms part of or constitutes the combat vehicle's weapon control system. In this embodiment, the training engine can receive information from the input device 45 or from Petition 870250092629, dated 10 / 10 / 2025, p. 21 / 108 12 / 42 input device 59 of the weapon control system, for example, the training engine can receive information from input device 59 directly without the use of the communication interface 35 described above. This also allows a configuration where the training functionality can be configured to be built into the weapon system (e.g., weapon control system) to provide training functionality as a complement to the traditional functionalities of the weapon control system. This allows for embedded crew training and, in particular, embedded artillery training using an existing combat vehicle without adding or modifying hardware of an already existing combat vehicle, since the training functionality can be configured only based on the addition and / or modification of existing combat vehicle software, such as software associated with the weapon system.Thus, embedded training can provide realistic artillery training during combat vehicle operation (e.g., while the combat vehicle is being operated, such as physically driven in a physical environment with the respective crew members positioned at their respective stations). This allows artillery training under the influence of the actual vehicle dynamics (e.g., the dynamics exhibited when traversing different types of ground conditions, such as rough terrain, slopes, and slippery terrain) and real environmental conditions (e.g., different visibility conditions, such as day, night, fog, sunlight, snow, rain, dense forest).

[0031] The training engine module 24 can be a single software program or application or, optionally, it can be distributed across a plurality of software modules stored in memory, each with different functionalities. The functionalities included in the training engine module include functionali Petition 870250092629, dated 10 / 10 / 2025, page 22 / 108 13 / 42 Functionality for determining the aiming direction of a combat vehicle weapon system based on data received from vehicle systems (e.g., weapon systems 55 including weapon control systems 58 and a weapon systems input device). This functionality also determines the location of a targeting point for the weapon system based on the weapon's aiming direction. The location of the weapon system's targeting point can be determined by the training engine module based on one or more user inputs representing one or more control signals that cause the weapon system's aiming direction to move along an azimuth and / or elevation direction.One or more user inputs are provided by the weapon system operator using input device 59 (e.g., a weapon system control handle, such as a sight) whereby one or more inputs, once provided, are transmitted to the electronic device 10 via a communication interface, such as via communication interface 35 described above. To determine a current aiming direction, the training motor module may also perform a determination of the weapon system's aiming direction based on one or more previous user inputs, such as the last user input received.

[0032] The location of the aiming point thus determines, based on said aiming direction, where a sight, such as the sight of an electronic sight (e.g., a camera with a sight) or an electronic target finder of the weapon system, must be placed in an environment and in relation to it (e.g., a simulated environment, as described in greater detail below) observed through the target finder, so as to allow the weapon system, when fired, to hit a position in the environment where the sight is positioned. Petition 870250092629, dated 10 / 10 / 2025, page 23 / 108 14 / 42

[0033] This functionality for determining a weapon system aiming direction including the location of the weapon system aiming point may also optionally include receiving indicative information of the weapon system aiming direction from a 58A sensor of the weapon control system.This 58A sensor can, for example, detect an attitude of the combat vehicle on which the weapon system is mounted and detect a current aiming direction of the weapon system compared to a reference aiming direction of the weapon system, wherein the reference aiming direction may be when the weapon system (e.g., a gun barrel of the weapon system) is aligned (e.g., running parallel) with a body of the combat vehicle, such as the body of the VB1 vehicle illustrated in Figures 2A-2C, and aligned (e.g., running parallel) with a forward direction of the combat vehicle, wherein the forward direction corresponds to a direction in which the combat vehicle is or will be driven forward.Thus, it can be said that this reference position corresponds to where the aiming direction of the weapon system is positioned with 0 degrees of deviation along an azimuth and 0 degrees of deviation along an elevation, as illustrated with reference to Figures 2A-2C. Alternatively, the 58A sensor can detect the attitude of the combat vehicle, and the relative positioning of the aiming direction of the weapon system in relation to the combat vehicle can be determined from other information, such as information indicating the positioning of the means of one or more actuators configured to control the aiming direction of the weapon system, as described in greater detail with reference to Figure 2A. For detecting the vehicle's attitude, an inertial measurement unit (IMU) can be used, such as an inertial measurement unit including an array of accelerometers. Petition 870250092629, dated 10 / 10 / 2025, page 24 / 108 15 / 42

[0034] With reference to Figure 1B, one or more 58A sensors, 58B of the weapon systems 55, as illustrated in Figure 1A, further comprise at least one image sensor 58B, wherein at least one said image sensor 58B is at least a targeting camera associated with said weapon system 55. According to one aspect of the present description, said image sensor 58B is a targeting camera associated with a main gun of a combat vehicle, for example, a combat vehicle 800 according to Figure 2A. At least one said image sensor 58B is arranged to obtain an IS image sequence (for example, a video sequence) comprising a plurality of I1, I2, I3 images. Furthermore, at least one said image sensor 58B, for example, a targeting camera, is arranged in connection with a respective weapon system, such as in connection with a main gun of said combat vehicle.The targeting camera is arranged to obtain a representative IS video sequence of a target area for a respective weapon system (e.g., a main gun, such as a cannon) of the combat vehicle, wherein the target area represents a section of the environment surrounding the combat vehicle, as determined from the targeting camera's aiming direction and field of view. The targeting camera comprises one or more cameras, such as a video camera and / or a thermal display (e.g., an infrared camera), and may also include or be coupled with one or more additional sensors, such as a laser rangefinder to determine the range to a target observed through the targeting camera. The targeting camera 58B is arranged to transmit the obtained image sequence to the electronic device 10 for display on the video device 40.For this purpose, the 58B targeting camera can be connected to a video network, such as an Ethernet network or bus (e.g., communication interface 35 and in). Petition 870250092629, dated 10 / 10 / 2025, page 25 / 108 16 / 42 peripheral interface 25 of the electronic device 10 illustrated in Figure 1A).

[0035] The functionalities of the training motor module 24 also include a target trajectory determination that allows the determination of one or more trajectories of a virtual target, such as a TR trajectory illustrated in Figure 3A and Figure 3C. The target trajectory can be determined based on one or more dynamic models (parametric model representing the movement of one or more types of targets) of one or more real targets with user-adjustable parameters (adjustable via input device 45). The adjustable parameters can be path or route, speed, maneuverability and / or a time period of trajectory duration. One or more of these adjustable parameters can also be linked to one or more configurable training difficulty settings described previously.For example, one or more training difficulty settings might include training difficulty levels 1-5, where the difficulty increases with the increase in the difficulty level. Thus, configuring the training engine by setting the difficulty level to 1 will make it relatively easy for a weapon system operator to track a respective virtual target presented during training, while setting the difficulty level to level 5 will make it relatively difficult for the weapon system operator to track the target. Training difficulty settings (e.g., levels) can be used to adjust more than one parameter at the same time with a single input.For example, each setting (level) can be associated with a specific speed or range of speeds according to which the virtual target will move during training; in addition, each setting can be associated with one or more predefined appearances, such as shape, size, and / or display contrast of the virtual target. Petition 870250092629, dated 10 / 10 / 2025, page 26 / 108. 17 / 42 actual, as presented during training.

[0036] Optionally, trajectories can be determined by the user selecting (through the use of input device 45) a target trajectory from a set of pre-stored target trajectories stored in memory. Optionally, a user can choose to use the dynamic target model or one or more of the pre-stored target trajectories. The pre-stored target trajectories can also include fixed-position targets. Target trajectories can be defined in a three-dimensional space. Optionally, target trajectories can be defined in a two-dimensional space.

[0037] The functionalities of the training engine module 24 also include target tracking accuracy determination. This functionality determines the time-based metrics associated with when the aiming point location, via operator input, is within a limit distance of the virtual target as it follows the target trajectory. This is described in greater detail with reference to Figures 3A-3D. This functionality also includes the scoring functionality provided based on the metrics to present a target tracking accuracy score to a weapon system operator.

[0038] The functionalities of training engine module 24 also include display control logic, such as a rendering engine, which allows training engine module 24 to generate (e.g., generate and display) a user interface of the video device 40 of the electronic device 10. According to an embodiment associated with Figures 3A-3B and 4A, training engine module 24 is arranged to display one or more graphic objects, described in greater detail with reference to Figures 3A-3B, superimposed on the IS image sequence obtained by the aiming camera. Petition 870250092629, dated 10 / 10 / 2025, page 27 / 108 18 / 42 58B. Thus, according to this embodiment, the video device 40 can be an existing display configured for use by a gunner to aim at a respective weapon system, but where the displayed image sequence IS is modified by the training engine to also include one or more superimposed graphic objects (e.g., one or more virtual targets). According to another embodiment, associated with Figures 3C-3D and 4B, the training engine module 24 generates a simulated environment (e.g., scenario S, as illustrated in Figures 3C-3D) for display in a user interface of the video device 40 together with one or more superimposed graphic objects (e.g., one or more virtual targets or one or more virtual targets and a crosshair to represent a current aiming point of a respective weapon system), as described in greater detail with reference to Figures 3C-3D.

[0039] Thus, according to the embodiment associated with Figures 3C-3D and 4B, the functions of the training engine module 24 also include environment simulation, for example, provided by a prototype engine of the training engine module. According to one aspect of this embodiment, the simulated environment generated by the environment simulation functionality of the training engine module is a two-dimensional environment. According to another aspect of this embodiment, the simulated environment generated by the environment simulation functionality of the training engine module is a three-dimensional environment. This allows the training engine module to generate a simulated environment representative of an environment around the combat vehicle.The prototype engine includes configurable parameters that allow a user (via input device 45) to configure the generated simulated environment, for example, with regard to weather conditions and day or night conditions (which affect visibility within the environment), terrain types, etc. Petition 870250092629, dated 10 / 10 / 2025, page 28 / 108 19 / 42 tion (e.g., winter or summer, etc.). To support the generation of terrain data from the simulated environment (such as a terrain database), texture data can be stored in memory. Additionally, a set of graphical objects is stored in memory, allowing a user to define user interface objects (e.g., allowing the user to define the appearance of graphical objects presented in a user interface displayed on the video device, such as the user interface described with references to 3C3D Figures). The configurable appearance can relate to how virtual targets are visualized by the rendering functionality in the user interface. For example, different types of targets can be configured to have a different appearance in terms of shape, size, and display contrast. It should be noted that the prototype engine can be configured as a separate software module stored in memory.

[0040] For the implementation associated with Figures 3C-3D and 4B, the rendering functionality, for example, provided by a rendering engine, is arranged to allow the training engine module to display a representation of at least part of the generated simulated environment in a video device user interface. This functionality also includes the display of graphic objects superimposed on the simulated environment, such as a first and second graphic object described in greater detail with reference to Figures 3C-3D. It should be noted that the rendering engine can be configured as a separate software module stored in memory. In addition, the rendering engine can also be configured with dedicated hardware, such as one or more graphics processing units and / or display control components.

[0041] Through input device 45, in accordance with Petition 870250092629, dated 10 / 10 / 2025, page 29 / 108 20 / 42. In conjunction with Figures 3C-3D and 4B, the user can define an initial simulation position (e.g., an initial simulation location, such as a ground plane position) of the simulated environment. This position (e.g., the initial simulation location) defines where, in the simulated environment, the combat vehicle should be positioned at the start of training (e.g., after the start of training). The position also includes additional information that defines a starting direction for the combat vehicle within the simulated environment. Furthermore, the direction can be configured via input device 45 or via input device 59. Thus, the initial position, including the direction of the vehicle at the initial position, is used to determine which part of the environment should be rendered on the video device, i.e., presented within the user interface.

[0042] To determine which part of the simulated environment to render on the video device, the rendering functionality can use the information associated with the simulated starting position, including the information associated with the starting direction. Thus, based on this information, the function can determine an observation point, of the combat vehicle, within the simulated environment, defining which part, that is, which section of the scenario, of the environment to render on the display.

[0043] Thus, the rendering functionality can display, on the video device, a first section of the simulated environment based on the starting point of the simulation and the initial simulation direction of the combat vehicle.

[0044] The rendering functionality also determines at least one or more secondary sections of the simulated environment and causes their rendering, that is, it updates the display of the displayed section of the simulated environment scenario. To determine at least one or more secondary sections of the simulated environment, the functionality uses information Petition 870250092629, dated 10 / 10 / 2025, page 30 / 108 21 / 42 Information associated with the initial simulation point and the initial simulation direction of the combat vehicle, along with one or more control signals and / or sensor data representative of the aiming direction of the weapon system. Optionally, this determination may also be based on control signals representative of control signals intended to cause the movement of the combat vehicle introduced through the drive control system 70. This allows changing the observation point in terms of which portion or section of the simulated environment is currently seen from the combat vehicle according to the movements of the combat vehicle (e.g., the simulated or real movement of the vehicle).

[0045] Optionally, this section, for example, the first or at least one or more second sections of the simulated environment, may be rendered based on the simulation of a field of view (FOV) of an optical instrument that is part of the combat vehicle's weapon control system, wherein the optical instrument may be an image target seeker (e.g., video camera-based target seeker or infrared target seeker). To this end, one or more camera transformations may be used to display a field of view of the environment as seen through the optical instrument. Furthermore, the relative positioning of this optical instrument on the combat vehicle may be taken into account for the simulation of the section of the environment seen through the optical instrument's field of view.

[0046] According to one embodiment, the function for determining the destination path also interfaces with the function for determining the simulated environment in order to provide the destination path within the simulated environment. This allows setting destination path parameters associated with defining a location within the simulated environment from which the path begins. Petition 870250092629, dated 10 / 10 / 2025, page 31 / 108 22 / 42

[0047] According to a coupled embodiment where the weapon system is kept stationary during training, as described above, the training engine functionality further includes determining the inertia of the weapon system. This allows for accurate simulation of the weapon system's aiming direction, determining how the weapon system will move as a result of operator inputs under the influence of inertia. To provide this determination, the training engine module may be provided with one or more models, stored in memory, such as one or more dynamic models representing how the weapon system moves as a result of operator inputs under the influence of inertia. This functionality will be disabled when the training engine module and / or the weapon system, as described above, is configured to allow real weapon system movements.

[0048] Figure 2A illustrates a perspective view of an exemplary combat vehicle 800 in which an electronic device, such as the electronic device 10 illustrated in Figure 1A, may be incorporated, as illustrated and described in greater detail with reference to Figure 2C, to provide training in target tracking of an incorporated combat vehicle weapon. The combat vehicle 800 comprises at least one integrated weapon system TG (e.g., combat vehicle weapon, such as a main gun). The combat vehicle may be a combat vehicle, such as an armored vehicle, a tank, or an infantry fighting vehicle. The combat vehicle illustrated in Figure 2A comprises a VB1 body, a T1 turret, and a turret-mounted TG cannon with a B1 cannon barrel. The VB1 vehicle body may comprise a chassis mounted by means of one or more suspension mechanisms (not shown) to ground engagement means (not shown), such as Petition 870250092629, dated 10 / 10 / 2025, p. 32 / 108 23 / 42 as tracks or wheels driven by one or more motors (not shown). The operator (e.g., a gunner) of the integrated weapon system, such as the main gun of the combat vehicle, can, using a weapon system control system, control a targeting direction PD of the gun barrel so as to aim the weapon at a target. In addition, for the input device, such as the input device 59 illustrated with reference to Figure 1A, the weapon control system, such as the weapon control system illustrated with reference to Figure 1A, also includes at least one actuator (not shown), such as at least one electro-hydraulic actuator to cause the movement of the targeting direction of the weapon system (e.g., the gun barrel) along an azimuth direction and / or along an elevation direction, as described in more detail with reference to Figures 2B-2C. Thus, by providing one or more control signals (e.g.,One or more control signals provided by an operator using input device 59) to the weapon control system generate one or more control commands based on the received control signals, wherein the control commands are transmitted to one or more actuators to cause one or more actuators to move in the aiming direction PD of the weapon system (e.g., the cannon barrel) in accordance with one or more control signals provided by a weapon system operator.

[0049] Figure 2B schematically illustrates a top view of the exemplary combat vehicle shown in Figure 2A. As can be seen in Figure 2B, the weapon system, in this case the main gun of the combat vehicle, is positioned in an azimuth aiming direction PD1 which, in the example shown, extends along the length of the main direction of the combat vehicle. To control the azimuth direction of the weapon (e.g., the barrel of the...) Petition 870250092629, dated 10 / 10 / 2025, page 33 / 108 24 / 42 (No B1) The crew member can provide one or more control signals through the input device 59 illustrated in Figure 1A, causing the weapon to move (i.e., rotate) along the azimuth direction AZ. For the weapon system illustrated, where the weapon system is configured as integrated into the turret, this also causes the turret to rotate.

[0050] Figure 2C schematically illustrates a side view of the exemplary combat vehicle illustrated in Figure 2A, in which the electronic device 10, as illustrated in Figure 1A, is incorporated into the vehicle and coupled to the vehicle systems 50.

[0051] As illustrated in Figure 2C, the weapon system can be additionally controlled along the azimuth direction AZ, as illustrated in Figure 2B, and also controlled to move along an elevation direction EL, causing movement of the elevation aiming direction PD2 of the weapon system (e.g., the cannon barrel B1). To control the elevation aiming direction of the weapon (e.g., the cannon barrel B1), the crew member can provide one or more control signals through the input device 59 illustrated in Figure 1A, thus causing the weapon to tilt along the azimuth direction EL. In Figure 2C, the weapon system can be seen slightly tilted upwards relative to a ground plane (not shown, but running parallel to an upper and / or lower surface of the vehicle body VB1) supporting the combat vehicle.

[0052] The azimuth aiming direction PD1 and the elevation aiming direction together constitute the aiming direction PD, as illustrated in Figure 2A.

[0053] Figure 3A schematically illustrates an exemplary user interface displayed on a video device of the electronic device, illustrated in Figure 1A, according to a concretization Petition 870250092629, of 10 / 10 / 2025, page 34 / 108 25 / 42 action.

[0054] In more detail, Figure 3A illustrates an exemplary user interface UI1 displayed by the electronic device, illustrated in Figure 1A, on the video device for the purpose of enabling embedded target tracking training that is performed in the combat vehicle.

[0055] Electronic device 10, as illustrated in Figure 1A obtains an IS image sequence from a 58B targeting camera associated with the combat vehicle's weapon system and causes the display of a UI1 user interface on a video device, such as a video device 40 of the electronic device 10, as illustrated in Figure 1A. The video device may be an existing video device in a combat vehicle, such as in combat vehicle 800, for example, a display associated with a gunner station and / or a weapon system, such as one or more respective weapons of the weapon system 55 of combat vehicle 800.

[0056] Thus, the UI1 user interface includes, i.e., displays, said IS image sequence, i.e., the IS image sequence provided by at least one image sensor that is composed of at least one targeting camera associated with the weapon system, for example, a targeting camera associated with a main weapon of the combat vehicle, as described with reference to Figure 1B. For illustrative purposes, the IS image sequence has been illustrated as a single triangle; however, the IS image sequence may represent any sequence of images from a targeting camera, such as a sequence of images containing a mountain or other type of environmental object captured within the targeting camera's field of view. It should be noted that the image sequence may be displayed in a larger portion of the user interface than in the example illustrated. Petition 870250092629, 10 / 10 / 2025, p. 35 / 108 26 / 42 of, as covering the entire user interface section.

[0057] The user interface also includes a first graphic object G1 superimposed on the IS image sequence, wherein the first graphic object is representative of the aiming point location, as determined from the aiming direction of the weapon system, as described in greater detail with reference to Figure 1A. Thus, the UI1 user interface of Figures 3A-3B displayed on the screen, including the IS image sequence and the first graphic object G1, may constitute an existing display in a combat vehicle, as configured for use by a vehicle gunner.

[0058] In addition, the user interface also includes a second graphic object G2, superimposed on the IS image sequence, where the second graphic object is representative of a virtual target that moves along a TR trajectory during a time period determined by the electronic device, as described in more detail with reference to Figure 1A.

[0059] In addition, the user interface optionally includes a graphical object M, such as a data field, which allows the display of metrics, including target tracking accuracy. The graphical object M that allows the display of metrics, including target tracking accuracy, is described in more detail with reference to Figure 3D.

[0060] The user interface or electronic device or one or more input devices associated with them also include a button or other suitable functionality to initiate target tracking training, including initiating the display of the virtual target. Optionally, the user interface, once invoked or displayed, displays the IS image sequence and the first graphic object, and a button or other suitable input functionality is included in the user interface or electronic device to cause the introduction (by Petition 870250092629, dated 10 / 10 / 2025, page 36 / 108 27 / 42 example, the display) of the virtual target, that is, to allow control over when the virtual target should be displayed and subsequently move along the determined trajectory. The position of the virtual target that the target assumes when training begins (for example, when invoking the training engine module or when causing the introduction / display of the virtual target) is also referred to as an initial position of the virtual target. This position corresponds to the first position of the determined trajectory. Optionally, this initial position corresponds to a position along the determined trajectory where the virtual target is currently positioned when causing the introduction / display of the virtual target.For example, the user can invoke the training engine module to cause the UI1 user interface to display the first graphical object and trigger the movement of the virtual target along the determined trajectory without displaying the virtual target, and subsequently trigger the display of the virtual target at a point in time after the movement is triggered, whereby the virtual target, as represented by the second graphical object, will be displayed at a position along the determined trajectory corresponding to when the virtual target moved and is currently positioned at that point in time, as determined by the speed of the determined trajectory.

[0061] As can be seen in Figure 3A, the first graphic object is positioned at a first location G1P1 in the user interface, that is, at a location on the video device. This location corresponds to the location of the weapon system's aiming point, as determined from a current aiming direction PD of the weapon system. Furthermore, the second graphic object, representing a virtual target, is displayed positioned at a second location G2P1 in the user interface. The virtual target is configured to follow a target trajectory TR for a period of time, as determined by the electronic device. In this way, Petition 870250092629, dated 10 / 10 / 2025, page 37 / 108 28 / 42 The user (e.g., the gunner of the combat vehicle) can now train target tracking by providing inputs (e.g., one or more control signals) through the weapon system's input device 59, causing movement of the weapon system's aiming direction and thus also the location of the aiming point, as reflected by the first graphic object. The objective is to track the virtual target as it moves over time as close as possible to the location of the weapon system's aiming point, as reflected by the first graphic object. Thus, when displaying the graphic objects, the video device updates the position of the respective first and second graphic objects, as displayed in the user interface, based on the information received and processed in the provided electronic device. The information is the trajectory determined for the virtual target and the aiming direction of the weapon system.

[0062] According to one embodiment, the first graphic object G1 is displayed as a cross and the second graphic object G2 is displayed as a circle or a sphere. According to an alternative embodiment, the second graphic object G2 is displayed as a graphic object with characteristics that resemble a real target (e.g., shape / contour and / or color can be adapted to resemble a live target, such as a tank). Furthermore, according to this embodiment, the size of the second graphic object can be adapted based on the trajectory determined for the virtual target and on a current position of the combat vehicle relative to a current position of the virtual target moving along the determined trajectory.

[0063] Figure 3B schematically illustrates an exemplary user interface displayed on a video device of the electronic device, illustrated in Figure 1A, according to an embodiment of the present invention. Petition 870250092629, dated 10 / 10 / 2025, p. 38 / 108 29 / 42

[0064] In Figure 3B, illustrating the user interface, as shown in Figure 3A, at a later time, it can be seen that the display of the first and second graphic objects was updated as a result of the movement of the virtual target along the determined target trajectory and based on the movements of the aiming direction of the weapon system as controlled by a weapon system operator (e.g., combat vehicle gunner). As illustrated in Figure 3B, the first graphic object G1 is updated to be displayed in a third position G1P2 different from the first position, and the second graphic object G2 was updated to be displayed in a fourth position G2P2 different from the second position.It should be noted that the first and second graphic objects can be updated to assume multiple intermediate positions compared to the positions illustrated in the example user interfaces of Figures 3A and 3B, as illustrated by a dashed line indicating the trajectory of the virtual target varying from location or position G2P1 to G2P2.

[0065] Figure 3C schematically illustrates an exemplary user interface displayed on a video device of the electronic device, illustrated in Figure 1A, according to one embodiment.

[0066] This implementation differs from the implementation associated with Figures 3A-3B show that the IS image sequence from the targeting camera, as displayed on display 40 associated with electronic device 10, as illustrated in Figure 1A, is replaced by a simulated environment (e.g., scenario S, as described below).

[0067] In more detail, Figure 3C illustrates an exemplary user interface UI1 displayed by the electronic device, illustrated in Figure 1A, on the video device for the purpose of enabling embedded target tracking training. The video device Petition 870250092629, dated 10 / 10 / 2025, page 39 / 108 30 / 42 deo may be an existing video device in a combat vehicle, such as in the 800 combat vehicle, for example, a display associated with a gunner station and / or a weapon system, such as one or more respective weapons of the 800 combat vehicle weapon system. 55

[0068] The user interface includes, that is, displays, the scenario S representative of a section of an environment, that is, the simulated environment provided by the electronic device, as described with reference to Figure 1A. For illustrative purposes, the scenario has been illustrated as a single triangle that may represent a mountain or other type of environmental object. It should be noted that the scenario may be displayed in a larger portion of the user interface than in the illustrated example, such as covering the entire user interface.

[0069] The user interface also includes a first graphic object G1 superimposed on the scene, where the first graphic object is representative of the location of the aiming point, as determined from the aiming direction of the weapon system, as described in more detail with reference to Figure 1A.

[0070] The user interface also includes a second graphic object G2, superimposed on the scene, where the second graphic object is representative of a virtual target that moves along a trajectory TR during a period of time determined by the electronic device, as described in more detail with reference to Figure 1A.

[0071] In this way, the user interface of Figures 3C-3D is similar to the user interface of Figures 3A-3B in terms of the inclusion of the respective first and second graphic objects, but differs in that the graphic objects are superimposed on a simulated environment instead of a sequence of images from a targeting camera.

[0072] The user interface also optionally includes an object Petition 870250092629, dated 10 / 10 / 2025, page 40 / 108 31 / 42 M chart, like a data field, that allows the display of metrics, including target tracking accuracy.

[0073] The user interface or electronic device also includes a button or other suitable functionality to initiate target tracking training, including initiating the display of the virtual target. Optionally, the user interface, once invoked or displayed, displays the scenario and the first graphical object, and a button or other suitable input functionality is included in the user interface or electronic device to cause the introduction (e.g., display) of the virtual target, i.e., to allow control over when the virtual target should be displayed and subsequently move along the determined trajectory. The position of the virtual target that the target assumes upon initiating training (e.g., upon invoking the training motor module or upon causing the introduction / display of the virtual target) is also referred to as the initial position of the virtual target. This position corresponds to the first position of the determined trajectory.Optionally, this initial position corresponds to a position along the determined trajectory where the virtual target is currently positioned when triggering the introduction / display of the virtual target. For example, the user can invoke the training engine module to cause the UI1 user interface to display the first graphical object and trigger the movement of the virtual target along the determined trajectory without displaying the virtual target, and then trigger the display of the virtual target at a point in time after the movement is triggered whereby the virtual target, represented by the second graphical object, will be displayed at a position along the determined trajectory corresponding to where the virtual target moved and is currently positioned at that point in time, as determined by the speed and the determined trajectory.

[0074] As can be seen in Figure 3C, the first graphic object Petition 870250092629, dated 10 / 10 / 2025, page 41 / 108 32 / 42 is positioned at a first location G1 P1 in the user interface, that is, at a location on the video device. This location corresponds to the aiming point location of the weapon system, as determined from a current aiming direction PD of the weapon system. Additionally, the second graphic object, representing a virtual target, is displayed positioned at a second location G2P1 in the user interface. The virtual target is configured to follow a target trajectory TR for a period of time, as determined by the electronic device.In this way, the user (e.g., the gunner of the combat vehicle) can now train target tracking by providing inputs (e.g., one or more control signals) through the weapon system's input device 59, causing movement of the weapon system's aiming direction and therefore also the location of the aiming point as reflected by the first graphic object. The objective being to track the virtual target as it moves over time as close as possible to the location of the weapon system's aiming point, as reflected by the first graphic object. Thus, when displaying the graphic objects, the video device updates the position of the respective first and second graphic objects, as displayed in the user interface, based on the information received and processed in the provided electronic device. The information is the trajectory determined for the virtual target and the aiming direction of the weapon system.

[0075] According to one embodiment, the first graphic object is displayed as a cross and the second graphic object is displayed as a circle or a sphere. According to an alternative embodiment, the second graphic object G2 is displayed as a graphic object with features that resemble a real target (e.g., shape / outline and / or color can be adapted to resemble a target). Petition 870250092629, dated 10 / 10 / 2025, page 42 / 108 33 / 42 live target, such as a tank). Furthermore, according to this embodiment, the size of the second graphic object can be adapted based on the trajectory determined for the virtual target and the current position of the combat vehicle relative to the current position of the virtual target moving along the determined trajectory.

[0076] Figure 3D schematically illustrates an exemplary user interface displayed on a video device of the electronic device, illustrated in Figure 1A, according to an embodiment of the present invention.

[0077] In Figure 3D, illustrating the user interface as shown in Figure 3C at a later time, it can be seen that the display of the first and second graphic objects was updated as a result of the movement of the virtual target along the determined target trajectory and based on the movements of the aiming direction of the weapon system as controlled by a weapon system operator (e.g., the combat vehicle gunner). As illustrated in Figure 3D, the first graphic object is updated to be displayed in a third G1P2 position different from the first position, and the second graphic object was updated to be displayed in a fourth G2P2 position different from the second position.It should be noted that the first and second graphic objects can be updated to assume multiple intermediate positions compared to the positions illustrated in the example user interfaces of Figures 3C and 3D, as illustrated by a dashed line indicating the trajectory of the virtual target varying from location or position G2P1 to G2P2.

[0078] In addition, the M metrics field displays a target tracking accuracy score of 250 points. This score, i.e., the target tracking accuracy score, is based on metrics associated with when the first graphic object is within a limit distance of the second graphic object, so as to allow. Petition 870250092629, dated 10 / 10 / 2025, page 43 / 108 34 / 42 assess target tracking accuracy. Thus, the score reflects the accuracy assessed over a period of time in which the operator (e.g., gunner) tracks the target by locating the aiming point. Consequently, as long as the first graphic object, which indicates where the operator aims the weapon system, is sufficiently close to the second graphic object (e.g., within a limit distance of the second graphic object), the target tracking accuracy score increases, and while the first graphic object is too far from the second graphic object (e.g., outside the limit distance), there is no increase in the tracking accuracy score.The target tracking accuracy score can be generated by an analysis module (not shown) of the training engine module 24, as illustrated in Figure 1A, wherein the analysis module is arranged to compare the distance between the respective first and second graphic objects over a period of time, such as a time period for when the virtual target is displayed. The analysis module can also determine a metric associated with the initial aiming accuracy performance associated with the time it takes for the gunner to aim the weapon system within a limit distance of the virtual target based on determining the time it takes from the initial appearance of the virtual target on the display until the aiming point is within the limit distance (e.g., counting the time from the initial appearance of the second graphic object until the first graphic object is within said limit distance).Furthermore, the analysis module can be arranged to store individual target tracking accuracy scores for one or more different individuals (e.g., gunners performing training). The analysis module can then sort the scores and display the currently highest stored score in the data field represented by the graphic object M in conjunction with the current score of the target tracker. Petition 870250092629, dated 10 / 10 / 2025, page 44 / 108 35 / 42 striker who is currently performing the training.

[0079] Figure 4A schematically illustrates a flow diagram of a method in a combat vehicle for training target tracking of an embedded combat vehicle weapon system that is performed on the electronic device of Figure 1A according to an embodiment of the present invention. The method for training target tracking of an embedded combat vehicle weapon system is configured to be performed in a combat vehicle, for example, the 800 combat vehicle, as described in Figure 2A. The method for training target tracking of the embedded combat vehicle weapon system is configured to be performed in a combat vehicle (see Figure 2A) on the combat vehicle's electronic device (see Figure 1A), wherein said electronic device comprises a video device and input means.

[0080] In block S1, a trajectory of a virtual target is determined. More specifically, a trajectory over a period of time is determined in the electronic device by running the training engine, as described in greater detail with reference to Figure 1A. More specifically, a trajectory of a virtual target over a period of time is determined in the electronic device with a video device and input media, as described in greater detail with reference to Figure 1A. The trajectory of the virtual target can, for example, be determined by the training engine module 24, as illustrated in Figure 1A.

[0081] In block S2, a targeting point location is determined. More specifically, the targeting point is determined based on a current aiming direction of the weapon system along an azimuth and an elevation direction, as described in greater detail with reference to Figures 1A-1B and Figures 2A-2B. More Petition 870250092629, dated 10 / 10 / 2025, page 45 / 108 36 / 42 in detail, the aiming point of the combat vehicle's weapon system is determined based on a current aiming direction of the weapon system along an azimuth and an elevation direction, as directed by means of operator inputs, as described in greater detail with reference to Figures 1A-1B and Figures 2A-2B.

[0082] In block S3, an image sequence is obtained, such as an IS image sequence, from a targeting camera associated with the combat vehicle's weapon system.

[0083] In block S4, the said IS image sequence is displayed on the video device. Also in block S4, a first graphic object is displayed on the video device, superimposed on the image sequence, wherein the first graphic object is representative of the aiming point location and displayed in a first position on the video device to indicate the determined aiming point location of the weapon system. Furthermore, in block S4, a second graphic object is displayed on the video device, superimposed on the image sequence, wherein the second graphic object is representative of the virtual target and displayed in a second position on the video device to indicate an initial position of the virtual target based on the trajectory determined over the time period;

[0084] In block S5, when displaying graphic objects, the display of the second graphic object is updated by moving the second graphic object from the second position along the determined trajectory during the time period. Additionally, in block S5, one or more user inputs are received, provided through input means; one or more user inputs representing one or more control signals that cause the movement of the weapon system's aiming direction along the azimuth and / or elevation direction are received and, in response to receiving one or more user inputs, the Petition 870250092629, dated 10 / 10 / 2025, page 46 / 108 37 / 42 display of the first graphic object is updated by moving the first graphic object from the first position according to the movement of the aiming direction of the weapon system caused by one or more user inputs.

[0085] In the S6 block, which is optionally executed, metrics over time are determined, where the metrics are associated with when (e.g., for how long over time) the first graphic object, described with reference to Figures 3A-3B, is within a limit distance relative to the second graphic object, described with reference to Figures 3A-3B. For example, the limit distance can be defined as a boundary from a central point of the second graphic object.

[0086] Figure 4B schematically illustrates a flow diagram of a method for training target tracking of an embedded combat vehicle weapon system that is performed on the electronic device of Figure 1A according to an embodiment of the present invention.

[0087] The method in Figure 4B differs from the method in Figure 4A in that the IS image sequence displayed according to the method in Figure 4A is replaced, in the method in Figure 4B, by a simulated environment (e.g., scenario S).

[0088] In block S11, a trajectory of a virtual target is determined. More specifically, a trajectory over a period of time is determined in the electronic device by running the training engine, as described in greater detail with reference to Figure 1A.

[0089] In block S12, a targeting point location is determined. In more detail, the targeting point is determined based on the weapon system's current aiming direction along an azimuth and an elevation direction, as described in more detail. Petition 870250092629, dated 10 / 10 / 2025, page 47 / 108 38 / 42 details with reference to Figure 1A and Figures 2A-2B.

[0090] In block S13, a representative scene of the first section of an environment is displayed on the screen. Also in block S13, a first graphic object is displayed on the video device, superimposed on the scene, where the first graphic object is representative of the aiming point location and is displayed in a first position on the video device to indicate the location of the weapon system's determined aiming point. Furthermore, in block S13 a second graphic object is displayed on the video device, superimposed on the scene, where the second graphic object is representative of the virtual target and is displayed in a second position on the video device to indicate an initial position of the virtual target based on the trajectory determined over the time period;

[0091] In block S14, when displaying graphic objects, the display of the second graphic object is updated by moving the second graphic object from the second position along the determined trajectory during the time period. Additionally, in block S14, one or more user inputs are received, provided through input means, one or more user inputs representing one or more control signals that cause the movement of the aiming direction of the weapon system along the azimuth and / or elevation direction are received and, in response to receiving one or more user inputs, the display of the first graphic object is updated by moving the first graphic object from the first position according to the movement of the aiming direction of the weapon system caused by one or more user inputs.

[0092] In the S15 block, which is optionally executed, the metrics over time are determined, where the metrics are associated with when (e.g., for how long over time) the first graphical object, described with reference to Petition 870250092629, dated 10 / 10 / 2025, page 48 / 108 39 / 42 Figures 3C-3D, is within a limiting distance relative to the second graphic object, described with reference to Figures 3C-3D. For example, the limiting distance can be defined as a boundary from a central point of the second graphic object.

[0093] According to yet another concretization, the methods of Figures 4A and / or 4B are performed on a combat vehicle turret, such as the 800 combat vehicle illustrated in Figure 2A. According to this embodiment, the electronic device 10, as illustrated in Figure 1A, is integrated into the turret and the turret is removed from the combat vehicle.
