Description

[Technical Field]

[0001] The present invention relates to the field of vision simulation, and more particularly to a flight-state based vision simulation method, system and device. [Background technology]

[0002] With the development of the aviation and aerospace fields, full-motion simulators have become an important tool for training pilots and astronauts. To enhance the realism of the simulated experience, vision systems are a crucial component of simulators, and their performance directly impacts training results. However, existing full-motion simulator control systems still have certain limitations in terms of simulation effectiveness. These systems are typically designed to be used in conjunction with a specific simulator manufacturer's simulator, such as the CAE Tropos system and the Collings RC system. While these control systems primarily provide basic functions such as opening and closing vision system projections and adjusting brightness, their control methods are often confined to each manufacturer's proprietary simulator system and are optimized for a specific projector, resulting in the following issues in terms of expressiveness in the simulation environment:

[0003] Compatibility issues: The control system is designed specifically for a certain brand or model of simulator, making it difficult to maintain compatibility with simulators from other brands, limiting the system's wide application across different simulation platforms.

[0004] Limited control functions: The existing control system has relatively simple functions, focusing mainly on basic operations such as opening and closing the vision system and adjusting the brightness, and does not fully utilize modern technological means to improve the simulation effect of the vision display.

[0005] Vision scene switching is not natural enough. During a long-term simulated flight, the flight environment (e.g., from daylight to dusk and then to night) changes continuously. However, conventional vision display systems only provide four non-continuous preset scenes: dawn, daylight, dusk, and night. Due to the lack of real-time access to flight simulation information, vision switching is not natural or smooth enough, which affects the overall realism and simulation experience of the simulated training.

[0006] In view of the above, the present invention proposes a flight state-based vision simulation method, system and device. Summary of the Invention [Problem to be solved by the invention]

[Figure 5] 1 is a structural schematic diagram of a server computer system for implementing the method, system and device embodiments of the present application; DETAILED DESCRIPTION OF THE INVENTION

[0027] The present application will be described in more detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are merely for the purpose of illustrating the relevant invention, and are not intended to limit the invention. Furthermore, for ease of explanation, only parts related to the relevant invention are shown in the drawings.

[0028] It should be noted that, unless there is a contradiction, the embodiments and features of the embodiments in the present application may be combined with each other. The present application will be described in detail below in combination with the embodiments with reference to the drawings.

[0029] In a first embodiment of the present invention, 1. A flight state based vision simulation method, the method comprising: Obtaining simulated parameters for the current simulated flight, including flight time, visibility parameters in the simulated environment, and a projector attenuation rate; Dividing the flight time into a plurality of sections, and calculating and obtaining a brightness percentage that the projector should project within each section according to the different sections in combination with the visibility parameter and the attenuation rate; Controlling the brightness percentage of the projected vision of the projector and tuning the color configuration parameters of the color wheel according to the flight state, thereby realizing the simulation of the flight state and the vision; A vision simulation method based on flight conditions is provided.

[0030] During a simulated flight that lasts for several hours, the simulated flight is constantly changing, for example, from daytime to dusk and then to night, and the flight scene is continuously changing. Conventional vision displays are divided into four non-continuous alternative scenes: dawn / day / dusk / night.

[0031] As can be seen, due to the lack of access to flight simulation information, as shown in Figure 2, the vision can only mechanically and artificially select from four common scenes, and the projection rates corresponding to their time zones are as shown in Table 1.

[0032] [Table 1]

[0033] As shown in Figure 3, this method obtains the projection power of the projector, assigns different powers according to different times, and associates it with the flight state. When entering a certain time zone, the power of that time zone is automatically retrieved and the projection brightness required for the current flight state is displayed. Taking an example where the minimum projection rate is the minimum dark field standard of the CAAC (Civil Aviation Administration of China), and the maximum projection power of the projector is 100, it was tested in an experiment associated with flight simulation and found that the projection power has a three-part functional relationship according to time and training scene.

[0034] In the present invention, the brightness percentage that the projector should project in different sections is calculated as follows: B L1 =5×(1-L dr )×V is / 8400,(h∈[23,4]), B L2 =(95h-335)×(1-L dr )×V is / 75600,(h∈(4,13]), B L3 =(447-19h)×(1-L dr )×V is / 16800,(h∈(13,23)), and where B is the brightness percentage and L dr is the attenuation rate of the projector, and V is is the visibility parameter, h is the time, L1, L2 and L3 are different intervals, and B L1 , B L2 and B L3 are the lightness percentages corresponding to the intervals L1, L2 and L3, respectively.

[0035] The projection display controlled by this method is not stepped but continuously variable, which is more suitable for the actual scene of flight training, and the projection rates corresponding to the time zones are as shown in Table 2.

[0036] [Table 2]

[0037] The above formula of the present invention takes into account the change in time h, and can simulate the change in natural light illumination at different times of the day. For example, light is typically weaker at dawn and dusk (h∈[23,4] and h∈(13,23)), but becomes stronger from noon to early afternoon (h∈(4,13]). The piecewise function in the formula allows for more accurate capture of such changes, resulting in a more realistic simulation.

[0038] Parameter V in the formula is represents visibility, and even within the same time period, if visibility is low (for example, on a foggy or rainy day), the brightness will also decrease accordingly. This helps simulate different weather conditions and increase the realism of training.

[0039] L in the formula dr represents the decay rate of the projector, which takes into account the decrease in brightness of the projector after long-term operation. By incorporating the decay rate into the calculation, the display effect can be maintained consistent and accurate.

[0040] Adjusting brightness using a non-linear formula (e.g., (95h-335) and (447-19h)) instead of a simple linear relationship can better mimic the complexity of how light intensity changes over time in the real world.

[0041] These parameters can be adjusted to optimize for different simulator hardware configurations and specific training needs. For example, if the simulator is installed in a low-light environment, the parameter V can be adjusted to match the actual environment. is may need to be adjusted.

[0042] The time zone division method allows for the flexible application of different brightness adjustment strategies within different time periods to adapt to the needs of various training scenes.

[0043] Thus, the design of these equations not only takes into account the time factor, visibility, and the physical characteristics of the projection equipment itself, but also provides sufficient flexibility to accommodate different simulated scenes, thereby enhancing the realism and effectiveness of flight simulator training.

[0044] As for tuning the color configuration parameters of the color wheel according to the present invention, the method comprises: Initializing one adjustable color wheel for adjusting RGB values, and setting corresponding color configuration data for preset visibility levels according to the color wheel; and controlling the projector to display visions with different combinations of color configurations and brightness percentages based on the color configuration data.

[0045] Based on the color wheel of the present invention, the corresponding color configuration data for the preset visibility levels are set as shown in Table 3.

[0046] [Table 3]

[0047] Here, the preset visibility levels according to the present invention in the table are, in order from highest to lowest, CAVOK, Category 1 Approach and Landing Standard, Category 2 Approach and Landing Standard, Category 3A Approach and Landing Standard, Category 3B Approach and Landing Standard, and Category 3C Approach and Landing Standard.

[0048] CAVOK (Ceiling And Visibility OK): Indicates clear skies, no cloud cover or clouds above 2000 feet, and horizontal visibility of at least 10 kilometers (6.2 miles).

[0049] CAVOK indicates that the weather conditions are good and very suitable for flying.

[0050] Category 1 Approach and Landing Standards CAT I (Category I): Refers to a Type 1 Instrument Landing System (ILS) that allows an aircraft to perform landing operations in specified weather minimums, requiring a minimum visibility of typically 800 meters (2600 feet) and a decision altitude (DA) typically of at least 60 meters (200 feet).

[0051] CAT II (Category II): Category 2 approach and landing standard, with lower minimum visibility and decision altitude requirements and more precision than CAT I, with minimum visibility typically 300 meters (1,000 feet) and decision altitude above 30 meters (100 feet).

[0052] CAT III (Category III): The Category 3 approach and landing standards are further divided into three subcategories: CAT IIIA, CAT IIIB, and CAT IIIC.

[0053] These categories allow aircraft to automatically land in almost any weather condition.

[0054] CAT IIIA: Category 3A approach and landing standard, meaning that the minimum visibility is less than 300 meters (1,000 feet), but there is no decision altitude requirement, allowing the aircraft to land fully automatically.

[0055] CAT IIIB: Category 3B approach and landing standard, allowing for lower visibility and greater autoland capability, e.g., visibility less than 150 meters (500 feet).

[0056] CAT IIIC: Category 3C approach and landing standard, providing a higher level of automation and allowing aircraft to land and taxi in zero visibility conditions.

[0057] The color configuration data according to the present invention includes at least RGB values, standard color codes, brightness, contrast, and saturation.

[0058] In this invention, specific intensity values ​​of red, green and blue are defined for each visibility level, and these values ​​are used to determine the color output of the vision system. For example, for class CAT I, the RGB values ​​are (250, 234, 245).

[0059] Color Code: In addition to the RGB values, a single hexadecimal color code, e.g. #FAEAF5, may also be included, which helps developers understand the color more intuitively.

[0060] The color configuration data may include additional configuration, version control information, and annotations.

[0061] Additional Configuration: In addition to the basic color configuration, some additional parameters may also be included, such as brightness, contrast, saturation, etc., which can adjust the overall visual effect of the vision system as needed.

[0062] Versioning Information: To track changes, configuration files may contain information such as version numbers and modification dates.

[0063] Annotation Explanation: For ease of maintenance and understanding, configuration files should also contain any necessary annotations to interpret the purpose and behavior of the configuration.

[0064] This method complies with the vision standard of the Civil Aviation Administration of China (CAAC). By adjusting the RGB color disk, this method aims to simulate the visual effects under different visibility conditions and ensure seamless integration with flight simulation systems.

[0065] The specific tuning process and implementation steps of the method may be as follows:

[0066] Tuning Process Choose or create an adjustable color wheel. Use your existing vision rendering software or develop a new interface that allows adjustment of RGB values.

[0067] Color composition is performed according to the defined values. For each visibility level, configure the color of the vision system using the RGB values ​​in the table above.

[0068] Save the configuration to the corresponding visibility level. Create a configuration file for each visibility level and save the RGB values.

[0069] Verify color accuracy and consistency. Compare the simulated environment with photos and video of the actual flight environment to ensure color accuracy and consistency.

[0070] Implementation steps Prepare your tools. Ensure that your vision system software supports RGB color adjustment. Prepare a database or file system to store the configuration.

[0071] Create a color configuration file. For each visibility level, create one configuration file containing the corresponding RGB values.

[0072] Apply color composition. In the vision system, the corresponding color configuration file is loaded according to the visibility level.

[0073] Integrate into flight simulation software. Integrate color configuration functionality into flight simulation software to ensure the vision system can dynamically adjust colors.

[0074] Test the system. The system is tested to ensure that the color scheme is accurate and compatible with the rest of the flight simulation system.

[0075] To control the brightness percentage of the projected vision of the projector according to the present invention, the method comprises: initializing a common standard interface protocol including at least a command format, a data packet structure, a communication protocol, and a preset command format for tuning color wheel parameters to control brightness percentage; defining required commands, including at least control commands, interface commands and simulation commands, based on the standard interface protocol, encoding the required commands, and transmitting the encoded commands to the projector; and decoding the encoded necessary instructions by the projector and performing operations corresponding to the necessary instructions, including tuning color configuration data and brightness percentages.

[0076] For the control command, such as switch on (PON), the projector will perform the switch-on operation. For the interface command and simulation command, the projector will perform the corresponding setting, query or simulation operation according to the specific command content.

[0077] The method of the present invention provides a common standard interface protocol that allows projectors external to the simulator to match the flight simulation system itself, maintaining consistency and accuracy in sending and receiving simulator system control commands, interface commands, and simulation commands. The protocol is independent of the projector and is not affected by the type or model of the projector. Different models of projection can provide their own interfaces. The protocol defines the communication patterns and rules for the control, interface, and simulation commands of the full-motion simulator's vision projector.

[0078] In the present invention, the control instructions include at least power on / off, resolution adjustment, brightness percentage setting and color configuration data, the interface instructions include at least parameter setting and status inquiry, and the simulation instructions include scene switching and special effect generation.

[0079] The necessary commands of the present invention are configured in the form of a string or code, and each command has a unique code so that the system can accurately identify and execute them, as shown in the following table.

[0080] [Table 4]

[0081] Tuning the color configuration data of the present invention is used to simulate visibility changes in different flight conditions, and tuning the brightness percentage is used to simulate different lighting environments.

[0082] The standard interface protocols described in this invention include the RS232 serial communication protocol or the TCP / IP network protocol.

[0083] In the above embodiment, each step is described in the above-mentioned order, but as can be understood by those skilled in the art, in order to achieve the effect of this embodiment, different steps do not need to be executed in this order, and they may be executed simultaneously (in parallel) or in the reverse order, and all of these simple variations are within the scope of protection of the present invention.

Whether these functions are ultimately implemented in the form of electronic hardware or software depends on the specific application and design constraints of the technical solution.
