[0027] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0028] Based on the above-mentioned problems existing in the prior art, the present invention mainly provides a simulation method, system, device and storage medium for a planetary probe. Its main purpose is to solve the problem in the prior art that there is a lack of an efficient and low-cost effective solution to assist technical personnel in quickly understanding and mastering the complex structure and functions of planetary probes.

[0029] Figure 1 A schematic flow chart of a simulation method for a planetary probe provided by an embodiment of the present invention. The method can be executed by a device, which can be implemented by software and / or hardware.

[0030] Figure 1 The simulation method of the planet probe is described in general. Figure 1 As shown, in this embodiment, the simulation method of a planetary probe includes steps S110 to S140.

[0031] Step S110: Generate a probe type selection directory on the interactive interface of a pre-created virtual simulation platform according to the acquired planet probe simulation instructions.

[0032] Specifically, the planet probe simulation instruction is issued in the form of clicking a button, inputting text or voice instructions, for example, a planet probe simulation button is created on the interactive interface of a pre-created virtual simulation platform, and when the user clicks the button, a planet probe simulation instruction is generated; or a text command box is created on the interactive interface of a pre-created virtual simulation platform, and a planet probe simulation instruction is generated according to the input planet probe simulation text command; or a voice receiving unit is created on the pre-created virtual simulation platform, and when the user issues a related voice command of the planet probe simulation instruction, a planet probe simulation instruction is generated. The above-mentioned planet probe simulation instruction generation method can be realized in the current computer field. According to the planet probe simulation instruction, a probe type selection directory is generated on the interactive interface of the pre-created virtual simulation platform, so that the user can select a certain type of planet probe that he wants to simulate operation.

[0033] As an optional embodiment of the present invention, a VR interface and a data interface are created on the virtual simulation platform, and a planet probe three-dimensional modeling unit and a model library are created in the virtual simulation platform, wherein the VR interface is used to connect a VR virtual device;

[0034] A data interface for receiving externally uploaded planetary probe structure data and probe simulation steps; wherein the planetary probe structure data includes the type of probe, components of different types of probes, and structural parameters of the components;

[0035] A planet probe three-dimensional modeling unit is used to create a three-dimensional model of the planet probe according to the planet probe structure data received by the data interface;

[0036] The model library is used to store different types of planetary probe three-dimensional models and to match corresponding probe simulation steps for different types of planetary probe three-dimensional models; wherein the probe simulation steps include an introduction to the overall mission of the planetary probe, an introduction to the functions of each component, the disassembly of the planetary probe, an introduction to the assembly sequence, and an introduction to the mission execution operations of the planetary probe.

[0037] Specifically, a virtual simulation platform is created in advance. The virtual simulation platform may include an interactive interface, which is used to interact with the user, for example, to provide the user with a probe type selection catalog. In order to enable the user to simulate the operation of the planetary probe in a virtual simulation environment, so as to understand the structure and function of the planetary probe more realistically and quickly, a VR interface is created on the virtual simulation platform for connecting the VR virtual device.

[0038] VR virtual devices can provide users with a friendly VR interactive interface, allowing users to interact with the planet probe model through VR helmets and controllers. The VR interactive interface class settings include functions such as toolbars, menus, and indicators to guide users to disassemble and assemble the planet probe model. It is also possible to improve the user's operational immersion by developing multimodal interaction methods and combining visual, tactile, and audio feedback. For example, the component allows users to directly interact with virtual objects (planet probe models) through VR controllers, such as grabbing, moving, rotating, etc. The gesture recognition function of the VR system is used to enable users to operate through gestures. It is also possible to integrate a voice recognition mechanism to allow users to control the probe through voice commands. Force feedback devices are used to simulate the tactile feeling when operating the probe, such as the pressing feeling of buttons and the damping feeling of knobs.

[0039] The data interface is used to receive externally uploaded planetary probe structure data and probe simulation steps; a planetary probe 3D modeling unit and a model library are created in the virtual simulation platform to process and store external data received by the data interface. Specifically, the planetary probe 3D modeling unit is used to create a planetary probe 3D model based on the planetary probe structure data received by the data interface; the model library is used to store different types of planetary probe 3D models, and to match the corresponding probe simulation steps for different types of planetary probe 3D models. Among them, when the planetary probe 3D modeling unit creates the planetary probe 3D model, it adopts a combination of reverse engineering and forward modeling, and uses high-precision laser scanning technology to obtain the shape and size data of the actual planetary probe components, and then accurately models them through 3D modeling software. According to the actual published data, the accuracy and details of the model are more in line with reality.

[0040] The three-dimensional model of the planetary probe includes its appearance, internal structure and components. These models accurately reflect the actual size and proportion of the probe. It is also possible to simulate its behavior in the actual space environment by writing programs for the components and operating subsystems of the three-dimensional model of the planetary probe, such as the ignition of the thrusters, the response of the navigation system and the data collection of the sensors. It is also possible to simulate the autonomous navigation system of the planetary probe, including star tracking, path planning and obstacle avoidance, so that users can observe and learn how the probe navigates without human intervention. That is, each type of three-dimensional model of the planetary probe is a dynamic three-dimensional model of the planetary probe in different behaviors or mission states in the space environment. Sensors and instruments such as cameras, radars, spectrometers, etc. can also be simulated on the three-dimensional model of the planetary probe, as well as the way they collect and transmit data.

[0041] As an optional embodiment of the present invention, according to the acquired planet probe simulation instruction, generating a probe type selection catalog on the interactive interface of the pre-created virtual simulation platform includes:

[0042] According to the obtained planet probe simulation instruction, real-time information on the type of the planet probe three-dimensional model stored in the model library of the virtual simulation platform is obtained;

[0043] According to the real-time information of the type, a detector type selection catalog is generated, and the detector type selection catalog is displayed on the interactive interface of the virtual simulation platform.

[0044] Specifically, when obtaining a planet probe simulation instruction, a probe type selection catalog is generated by accessing the real-time information of the type of the current planet probe three-dimensional model in the model library of the virtual simulation platform to ensure that each type of probe included in the probe type selection catalog for user selection is a planet probe three-dimensional model that can be obtained in the model library, thereby avoiding the problem of information lag in the probe type selection catalog. Among them, the order of different types of probes in the probe type selection catalog can be sorted according to the generation time of the planet probe three-dimensional model or the importance level marked when it was stored.

[0045] Step S120, obtaining a planetary probe three-dimensional model and a corresponding probe simulation step corresponding to the feedback information of the probe type selection catalog from the model library of the virtual simulation platform, as the target probe model and the target probe simulation step respectively.

[0046] Specifically, the user can select the type of probe they want to simulate in the probe type selection catalog to generate corresponding feedback information, and obtain the corresponding planetary probe three-dimensional model and the corresponding probe simulation steps from the model library based on the feedback information, and use them as the target probe model and target probe simulation steps, respectively.

[0047] Step S130: Based on VR virtual reality technology, the target detector model is rendered in the VR virtual device as a VR virtual interactive space, and the pre-matched operating components on the components of the target detector model are integrated on the interactive device connected to the outside of the virtual simulation platform.

[0048] Specifically, the target detector model is rendered as a VR virtual interactive space in the VR virtual device. By wearing the VR virtual device, the user is placed in the VR virtual interactive space, which increases the realism of the user's interaction with the target detector model. By integrating the pre-matched operating components on the components of the target detector model on the interactive device connected to the outside of the virtual simulation platform, it is convenient for the user to interact with the target detector model in the VR virtual interactive space by actually operating the interactive device, thereby increasing the sense of reality. The key functions of the detector, such as navigation, sample collection, and data analysis, can be simulated by developing algorithms. Adaptive algorithms are implemented to adjust the simulation difficulty and feedback according to the user's operating habits and learning progress.

[0049] As an optional embodiment of the present invention, rendering the target detector model into a VR virtual interaction space in a VR virtual device based on VR virtual reality technology includes:

[0050] Connect the VR virtual device to the VR interface of the virtual simulation platform, so that the target detector model is displayed on the interactive interface of the VR virtual device;

[0051] According to the acquired scene change instruction, a scene selection list is generated on the interactive interface of the VR virtual device;

[0052] Acquire a virtual scene corresponding to the feedback information of the scene selection list from a virtual scene library of the virtual simulation platform;

[0053] Render the virtual scene to the interactive interface of the VR virtual device to form a VR virtual interactive space.

[0054] Specifically, the VR virtual device is connected to the VR interface of the virtual simulation platform. At this time, the target detector model is displayed on the interactive interface of the VR virtual device. When the processor receives the information that the VR virtual device is successfully connected to the VR interface, it can send a scene change prompt to the user through the interactive interface of the VR virtual device. The user issues a scene change instruction through the interactive interface of the VR virtual device. The scene change instruction can be issued by buttons, voice, or text. According to the scene change instruction, the virtual scenes in the virtual scene library of the virtual simulation platform are visited, and then a scene selection list is generated for the user to choose. The user obtains the virtual scene corresponding to the feedback information of the scene selection list from the virtual scene library of the virtual simulation platform, and renders the virtual scene to the interactive interface of the VR virtual device to form a VR virtual interactive space to simulate various space environments that the target detector may encounter, including different planetary surfaces, solar radiation, micrometeoroids, etc., and their impact on the behavior of the detector, to increase the user's real experience.

[0055] In the process of creating virtual scenes, the gravity parameters in the virtual environment are set according to the actual gravitational acceleration of Mars and the Moon (planet) (the Moon is about 1 / 6 of the Earth, and Mars is about 38% of the Earth); simulate sunlight, including the position, light intensity and color of the sun, taking into account the different distances between Mars and the Moon (planet) and the Earth; use physical-based rendering technology (PBR) to simulate and render the visual appearance of the environment, including surface materials, skybox, etc.; develop a parameter adjustment system to allow users to update environmental parameters in real time based on actual detection data; simulate how sensors on planetary probes respond to environmental changes, such as thermometers, barometers and radiometers; provide multi-scale environmental simulation from microscopic (such as the probe surface) to macroscopic (such as the entire Martian or lunar landscape). The simulation methods for landform features in virtual scenes include: detailed three-dimensional modeling of landform features such as mountains, plains, and craters based on geological research and actual detection data, including terrain textures and color maps, to achieve realistic visual performance. The simulation method for the astrophysical environment in the virtual scene is: integrate the physics engine to simulate the gravity environment of Mars and the Moon (planet), set the gravity acceleration parameters according to the principles of astrophysics, and realize the physical simulation of the movement and interaction of objects. The simulation method for atmospheric pressure and lighting conditions in the virtual scene is: simulate the impact of atmospheric pressure on the planetary probe and user vision. Adjust the lighting model to simulate the lighting effects under different sunlight conditions, including shadows and the color temperature of light. Temperature change simulation: simulate the impact of temperature changes on probe performance and user perception based on the temperature data of Mars and the Moon. In the VR environment, temperature changes can be expressed through visual cues (such as thermal fluctuations) or tactile feedback. Visual feedback can use high-quality graphics rendering technology, including physically based rendering (PBR), lighting and shadow processing, to provide users with a realistic visual experience. Auditory feedback can design corresponding audio effects based on the acoustic characteristics of Mars and the Moon. Although the atmosphere of these celestial bodies is very thin, the sound of probe movement and operation, as well as environmental noise, can be simulated. The tactile feedback class uses force feedback devices, such as VR gloves or tactile vests, to simulate the user's physical interaction with the virtual environment, such as the feeling of resistance when grabbing, pushing, and walking. Multimodal interaction combines visual, auditory, and tactile feedback to provide a multimodal interactive experience. For example, when a user walks in a virtual environment, he or she can not only see the ground and hear the footsteps, but also feel the texture of the ground through tactile feedback.

[0056] As an optional embodiment of the present invention, the VR virtual device is a VR helmet or VR glasses; the interactive device is a handle or a controller.

[0057] Specifically, the VR virtual device is a currently available VR helmet or VR glasses; the interactive device is preferably, but not limited to, a handle or controller. By setting simulation keys on the handle or controller, a corresponding association relationship is established with the operating components, so that the user's operation in the real environment is closer to the operation of the real detector. The handle or controller is used for the user to simulate the control of the target detector model in the VR virtual interactive space, which may include the decomposition and assembly of each component; as well as the task instruction control of the detector, such as starting the detector, controlling the direction, activating the instrument, etc.

[0058] The physics engine can be integrated into the VR virtual device to enable the target detector model to simulate physical phenomena such as gravity, collision, and friction in the VR virtual interactive space. The physics engine ensures that the movement and interaction of the target detector model follow the physical laws of the real world. It is preferred to use an advanced physics engine, such as Unity3D's PhysX or Unreal Engine's Chaos physics system, to simulate basic physical phenomena such as gravity, collision, and friction. Specific steps may include: integrating the physics engine as a plug-in or module into the VR virtual device in a development environment such as Unity3D or Unreal Engine; importing the target detector model into Unity3D or Unreal Engine; adding collider components, such as box collider, sphere collider or mesh collider, to various parts of the target detector model, and adding rigid body components to the target detector model, which are components used in the physics engine to simulate the movement of real objects; assigning physical materials to the colliders, defining physical properties such as friction and elasticity, setting the gravity vector in the virtual environment to simulate the gravity effect of the detector on different celestial bodies; if the target detector model contains movable parts, using hinge joints, ball joints or other types of physical joints to simulate its movement; for parts that need to consider air resistance, fluid simulation can be added or an aerodynamic model can be used to calculate the resistance; adjusting the parameters of the physics engine, such as gravity constant, time step, collision detection accuracy, etc., according to the expected behavior of the target detector model. In the development environment, each planet probe 3D model is physically simulated and tested to see whether its behavior is as expected, and adjustments and optimizations are made as needed.

[0059] Step S140: Based on the target detector simulation step, according to the control instructions for the operating components issued by the interactive device, the target detector model is simulated in the VR virtual interactive space.

[0060] Specifically, according to the target detector simulation steps, prompts are given to the user in sequence to enable the user to complete the target detector simulation steps. Each step is controlled by the user through the interactive device, and the interactive device issues control instructions to the operating components, thereby completing the simulation operation of the target detector model in the VR virtual interactive space. Among them, the simulation operation includes the disassembly, assembly and task execution of the components of the target detector model. Task execution is such that if the detector has a sample collection function, its collection process, as well as the working principle and data analysis process of the sample analysis instrument are simulated. Possible failure situations can also be simulated, such as instrument failure, communication interruption, etc., to train users how to diagnose problems and take countermeasures.

[0061] For example, mission execution includes inspection, sampling, and analysis. The inspection mission operator controls the probe to move in the virtual environment to observe and record information such as topography, special landmarks, etc. Use a VR controller to simulate the movement and navigation system of the probe to achieve path planning and real-time control of the probe. Sampling mission: simulate the probe's robotic arm or sampler to collect materials, such as rock, soil or atmospheric samples. Design an interactive robotic arm control interface to achieve precise grasping, collection and storage of samples. Analysis mission: simulate the scientific instruments carried by the probe to analyze the chemical composition, structure, etc. of the collected samples. By developing a virtual scientific instrument interface, after entering the sample data, the analysis results and scientific explanations are displayed.

[0062] As an optional embodiment of the present invention, based on the target detector simulation step, according to the control instruction for the operation component issued by the interactive device, the target detector model is simulated in the VR virtual interactive space, including:

[0063] The user issues control instructions to the operation component through the interactive device according to the target detector simulation steps, so that the operation component controls the components of the corresponding target detector model to perform actions according to the control instructions in the VR virtual interactive space;

[0064] In the process of controlling the components of the corresponding target detector model to perform actions according to the control instructions, the user's gesture or body posture data is captured through the built-in sensors of the VR virtual device;

[0065] The angle of the target detector model in the VR virtual interaction space is adjusted based on the user's gesture or body posture data until all the target detector simulation steps are executed, completing the simulation operation of the target detector in the VR virtual interaction space.

[0066] Specifically, the processor obtains the user's gesture or body posture data obtained by the built-in sensor of the VR virtual device, and then adjusts the angle of the target detector model in the VR virtual interactive space based on the user's gesture or body posture data, so that the target detector model faces the user at the best angle. An angle adjustment key can be set on the interactive interface of the VR virtual device to adjust to different viewing angles according to user needs, so that the user can observe the detector from different viewing angles and switch between different views, such as first-person perspective, third-person perspective, top view, side view, etc.

[0067] As an optional embodiment of the present invention, based on the target detector simulation step, according to the control instruction for the operation component issued by the interactive device, after performing a simulation operation on the target detector model in the VR virtual interactive space, the method further includes:

[0068] Obtain the whole process data of the simulated operation of the target detector in the VR virtual interactive space;

[0069] The whole process data of the simulation operation is input into the preset simulation evaluation model, and the whole process data of the simulation operation is analyzed by the preset simulation evaluation model to generate a simulation operation score for the target detector.

[0070] Specifically, when all simulation operations are completed, the whole process data of the simulation operation is obtained, and the simulation operation of the current user is analyzed through the pre-trained preset simulation evaluation model, and the operation score is given. Among them, the preset simulation evaluation model can be obtained through neural network training, and the operation score can be obtained by arranging multiple indicators and weighted summing them, for example, task completion time, resource consumption and error rate and the corresponding weights of each item, and obtained by summing them.

[0071] like Figure 2 As shown, the present invention provides a planet probe simulation system 200, which can be installed in an electronic device. According to the functions to be implemented, the planet probe simulation system 200 may include: a catalog generation module 210, a target model acquisition module 220, a virtual interactive space rendering module 230, and a simulation operation module 240. The unit of the present invention may also be referred to as a module, which refers to a series of computer program segments that can be executed by an electronic device processor and can complete fixed functions, which are stored in the memory of the electronic device.

[0072] In this embodiment, the functions of each module / unit are as follows:

[0073] A catalog generation module 210 is used to generate a catalog of probe type selection on an interactive interface of a pre-created virtual simulation platform according to the acquired planet probe simulation instructions;

[0074] A target model acquisition module 220 is used to acquire a planetary probe three-dimensional model and a corresponding probe simulation step corresponding to the feedback information of the probe type selection catalog from the model library of the virtual simulation platform as a target probe model and a target probe simulation step, respectively;

[0075] A virtual interactive space rendering module 230 is used to render the target detector model into a VR virtual interactive space in a VR virtual device based on VR virtual reality technology, and integrate pre-matched operating components on various components of the target detector model on an interactive device connected to the outside of the virtual simulation platform;

[0076] The simulation operation module 240 is used to perform simulation operations on the target detector model in the VR virtual interaction space based on the target detector simulation step and according to the control instructions for the operation component issued by the interactive device.

[0077] The planetary probe simulation system 200 of the present invention first generates a probe type selection catalog on the interactive interface of a pre-created virtual simulation platform according to the obtained planetary probe simulation instructions; then obtains the planetary probe three-dimensional model and the corresponding probe simulation steps corresponding to the feedback information of the probe type selection catalog from the model library of the virtual simulation platform as the target probe model and the target probe simulation steps, and then based on VR virtual reality technology, renders the target probe model in the VR virtual device as a VR virtual interactive space and integrates the pre-matched operating components on the components of the target probe model on the interactive device connected to the outside of the virtual simulation platform, so that the user, i.e. the technician, can issue control instructions to the operating components according to the target probe simulation steps in the VR virtual interactive space by manipulating the interactive device to simulate the target probe model, so that the user, i.e. the technician, can quickly understand and master the structure and operation of the planetary probe by intuitively understanding the planetary probe and the simulation operation in the virtual simulation environment, so as to facilitate subsequent research and development and maintenance. The present invention can greatly shorten the training cycle of technicians and efficiently complete the technical training of probes under low cost conditions.

[0078] like Figure 3 As shown, the present invention provides an electronic device 3 for a simulation method of a planetary probe.

[0079] The electronic device 3 may include a processor 30, a memory 31 and a bus, and may also include a computer program stored in the memory 31 and executable on the processor 30, such as a simulation program 32 of a planetary probe.
