Description

Background Art

[0002] With the rapid development of the civil aviation industry, flight safety has gradually become one of the core issues of concern to all sectors of society. In order to ensure flight safety, it is particularly important to improve pilots' operating skills and their ability to respond to emergencies. In this context, flight simulation training has been widely adopted because it can provide learning conditions close to the real flight environment and has become a key link in pilot training. As the core equipment in this training process, the performance of the flight simulator is directly related to the effectiveness of the training results and the pilot's future flight performance.

[0003] In a flight simulator, the visual system plays a vital role. It is responsible for providing pilots with realistic flight environment images, helping them better understand and adapt to various flight conditions. Therefore, the accuracy and realism of the visual system are crucial to ensure the quality of simulation training.

[0004] However, in current technical practice, the traditional theodolite measurement method commonly used in the domestic market has obvious limitations in obtaining the geometric data of the vision system. On the one hand, due to the huge amount of data that needs to be processed, manual analysis under traditional methods is not only time-consuming and laborious, but also prone to human errors, which seriously affects work efficiency and the accuracy of data analysis. On the other hand, even if some international suppliers provide more advanced measurement and verification solutions, such as accurate measurement and verification of the geometry of the vision system through proprietary software, such technologies usually adopt a closed development model and do not disclose specific algorithm details to the outside world. This practice not only hinders the advancement of related domestic technologies, but may also lead to excessive dependence on foreign technologies.

[0005] Based on this, the present invention proposes a method, system, device and storage medium for analyzing wide-area visual geometry data of a full-motion flight simulator. Summary of the invention

[0006] In order to solve the above problems in the prior art, namely, the problems that the traditional theodolite measurement method is inefficient and prone to errors, the present invention provides a method, system, device and storage medium for analyzing wide-area visual geometry data of a full-motion flight simulator.

[0023] If the difference between the adjacent angular spacing and the second tolerance standard data does not exceed the second angle threshold range, it is classified into the third condition; if the difference between the adjacent angular spacing and the second tolerance standard data exceeds the second angle threshold range, it is classified into the fourth condition;

[0024] Only when the first and third conditions are met at the same time can the tolerance requirements be met. If the second or fourth condition is met, the tolerance requirements are not met.

[0025] In some preferred implementations, after obtaining a plurality of unit geometric figures, a corresponding entry identification is established for each unit geometric figure and a standard system vision system.

[0052] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] The present invention provides a method for analyzing wide-area visual geometric data of a full-motion flight simulator, the method comprising:

[0055] Acquire an image in a flight simulator visual system, and divide the image in a horizontal direction and a vertical direction at interval angles preset in a standard system visual system to obtain a plurality of unit geometric figures;

[0056] Obtaining angle data of each end point of each unit geometric figure at the pilot's viewpoint;

[0057] According to the angle data, respectively obtain the uniform angular spacing of each unit geometric figure in the horizontal direction and the vertical direction, and the adjacent angular spacing of two adjacent unit geometric figures in the horizontal direction and the vertical direction;

[0058] The difference between the uniform angular spacing and the adjacent angular spacing and the standard data in the standard system vision system is obtained, and combined with the preset conditions, the angle data that meets the tolerance and / or exceeds the tolerance is classified; wherein the preset condition is: when the difference between the uniform angular spacing and the difference between the adjacent angular spacing are both less than the threshold value, the tolerance is met, and the angle data of the corresponding geometric figure is used as the angle data that meets the tolerance.

[0059] In order to more clearly explain the method for analyzing wide-area visual geometric data of a full-motion flight simulator of the present invention, the following is combined with Figure 1-Figure 4 Each step in the embodiment of the present invention is described in detail as follows:

[0060] Acquire an image in a flight simulator visual system, and divide the image in a horizontal direction and a vertical direction at interval angles preset in a standard system visual system to obtain a plurality of unit geometric figures;

[0061] The spacing angle in this embodiment is preferably 5°.

[0062] Taking the S76 helicopter as an example, its field of view is 210 degrees horizontally / 30 degrees vertically upward / 50 degrees vertically downward. Within the above field of view, the horizontal and vertical directions are divided at intervals of 5° to obtain multiple unit geometric figures. The unit geometric figure in the present invention can be understood as a 5° square.

[0063] Obtaining angle data of each end point of each unit geometric figure at the pilot's viewpoint;

[0064] Specifically, the initial angle of each end point of each unit geometric figure is obtained through the theodolite at the pilot's viewing angle, and the initial angle is converted into degree data as angle data;

[0065] The initial angle is arc-minute-second data.

[0066] Since the flight simulator vision system cannot be consistent with the standard vision system, its reflective medium will be distorted due to the limitations of materials and process level, resulting in a gap between the flight simulator geometry data and the geometry data of the standard vision system. Through the theodolite, the horizontal angle data and vertical angle data of multiple data collection points located at the pilot's viewpoint can be collected. These are the original geometry angle data, which need to be compared with the standard data stored in the geometry database of the standard vision system. For aircraft with two pilot seats, data collection is required for the captain's seat, the co-pilot seat, and the center viewpoint between the two seats, that is, there are multiple sets of data collection points.

[0067] The data obtained from the theodolite are angle data in degrees, minutes and seconds. They need to be stored in separate items and then converted into degree data. The difference between the angle data and the standard data of the same data point stored in the geometric graphics database of the standard vision system is the data that needs to be identified and determined.

[0068] According to the angle data, respectively obtain the uniform angular spacing of each unit geometric figure in the horizontal direction and the vertical direction, and the adjacent angular spacing of two adjacent unit geometric figures in the horizontal direction and the vertical direction;

[0069] Among them, when calculating the uniform angular spacing of multiple unit geometric figures, the direction of the vertical field of view follows the order from top to bottom, and the direction of the horizontal field of view follows the order from left to right, and the adjacent data are calculated in sequence; when calculating the adjacent angular spacing of multiple unit geometric figures, the direction of the vertical field of view follows the order from top to bottom, and the direction of the horizontal field of view follows the order from left to right, and the interval data are calculated in sequence.

[0070] Among them, Figure 2 and Figure 3 As shown, calculating the uniform angular spacing and the adjacent angular spacing is regarded as the first difference comparison.

[0071] In this embodiment, the uniform angular spacing is calculated as follows:

[0072] The angle difference between two adjacent end points of a single unit geometric figure in the horizontal direction is taken as the uniform angular spacing in the horizontal direction;

[0073] The angular difference between the two adjacent end points in the vertical direction of a single unit geometric figure is taken as the uniform angular spacing in the vertical direction.

[0074] The adjacent angular spacing is calculated as follows:

[0075] The angle difference between two non-coincident points of two adjacent unit geometric figures in the horizontal direction is taken as the adjacent angular spacing in the horizontal direction;

[0076] The angular difference between two non-coincident points in the vertical direction of two adjacent unit geometric figures is taken as the adjacent angular spacing in the vertical direction.

[0077] The difference between the uniform angular spacing and the adjacent angular spacing and the standard data in the standard system vision system is obtained, and combined with the preset conditions, the angle data that meets the tolerance and / or exceeds the tolerance is classified; wherein the preset condition is: when the difference between the uniform angular spacing and the difference between the adjacent angular spacing are both less than the threshold value, the tolerance is met, and the angle data of the corresponding geometric figure is used as the angle data that meets the tolerance.

[0078] The calculated differences between the uniform angular spacing and the adjacent angular spacing and the standard tolerance data are regarded as the second difference comparison. In this embodiment, the first standard tolerance data and the second standard tolerance data are the standard uniform angular spacing (5°) and the standard adjacent angular spacing (10°), respectively.

[0079] The preset conditions are:

[0080] If the difference between the uniform angular spacing and the first tolerance standard data does not exceed the first angle threshold range, it is classified into the first condition; if the difference between the uniform angular spacing and the first tolerance standard data exceeds the first angle threshold range, it is classified into the second condition;

[0081] If the difference between the adjacent angular spacing and the second tolerance standard data does not exceed the second angle threshold range, it is classified into the third condition; if the difference between the adjacent angular spacing and the second tolerance standard data exceeds the second angle threshold range, it is classified into the fourth condition;

[0082] Only when the first and third conditions are met at the same time can the tolerance requirements be met. If the second or fourth condition is met, the tolerance requirements are not met.

[0083] In this embodiment, the first angle threshold range is ±1°, and the second angle threshold range is ±1.5°.

[0084] like Figure 3 As shown, the geometric figures of the standard vision system are all standard 5-degree squares, but these squares will be distorted when displayed by the flight simulator vision system. At this time, the angle data of each sampling point is obtained by measuring with a theodolite.

[0085] like Figure 4As shown, in the standard vision system, at the data point with a horizontal angle of 20 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 20.1 degrees and a vertical angle of 10.1 degrees; at the data point with a horizontal angle of 25 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 25.2 degrees and a vertical angle of 10 degrees; at the data point with a horizontal angle of 30 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 30.3 degrees and a vertical angle of 10.2 degrees.

[0086] The uniform angular spacing of the 5º squares in the horizontal direction of this set of data are 25.2 degrees - 20.1 degrees = 5.1 degrees and 30.3 degrees - 25.2 degrees = 5.1 degrees, respectively, which is classified as the first condition and meets the requirement that the uniform angular spacing of a 5º square does not exceed ±1º. The adjacent angular spacing of adjacent squares is 30.3 degrees - 20.1 degrees = 10.2 degrees, which is classified as the third condition and meets the requirement that the angular spacing of adjacent squares exceeds ±1.5º. This means that both the uniform angular spacing and the adjacent angular spacing are qualified.

[0087] In the standard vision system, at the data point with a horizontal angle of 20 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 19.6 degrees and a vertical angle of 10 degrees; at the data point with a horizontal angle of 25 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 25.7 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 30 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 30.3 degrees and a vertical angle of 10 degrees.

[0088] The uniform angular spacing of 5º squares in the horizontal direction of this set of data is 25.7 degrees - 19.6 degrees = 6.1 degrees and 30.3 degrees - 25.7 degrees = 4.6 degrees. One of them is classified as the second condition, which does not meet the requirement that the uniform angular spacing of a 5º square does not exceed ±1º (that is, the tolerance range is 4 º to 6 º). The adjacent angular spacing of its adjacent squares is 30.3 degrees - 19.6 degrees = 10.7 degrees, which meets the requirement that the angular spacing of adjacent squares exceeds ±1.5º (that is, the tolerance range is 8.5 º to 11.5 º), and is classified as the third condition. This means that the uniform angular spacing is unqualified, but the adjacent angular spacing is qualified.

[0089] In the standard vision system, at the data point with a horizontal angle of 20 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 19.5 degrees and a vertical angle of 10 degrees; at the data point with a horizontal angle of 25 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 25.3 degrees and a vertical angle of 10 degrees; at the data point with a horizontal angle of 30 degrees and a vertical angle of 10 degrees, if the measured data is a horizontal angle of 31.1 degrees and a vertical angle of 10.2 degrees.

[0090] The uniform angular spacing of 5º squares in the horizontal direction of this set of data is 25.3 degrees - 19.5 degrees = 5.8 degrees and 31.1 degrees - 25.3 degrees = 5.8 degrees, respectively. This is classified as the first condition, which meets the requirement that the uniform angular spacing of a 5º square does not exceed ±1º (i.e., the tolerance range is 4 º to 6 º). The adjacent angular spacing of adjacent squares is 31.1 degrees - 19.5 degrees = 11.6 degrees, which does not meet the requirement that the angular spacing of adjacent squares exceeds ±1.5º (i.e., the tolerance range is 8.5 º to 11.5 º), and is classified as the fourth condition. This means that the uniform angular spacing is qualified, but the adjacent angular spacing is unqualified.

[0091] The judgment in the vertical direction is similar and will not be elaborated here.

[0092] In this embodiment, after obtaining a plurality of unit geometric figures, a corresponding entry identification is established for each unit geometric figure and the standard system visual system.

[0093] By assigning a unique entry identifier to each unit geometry and establishing a corresponding relationship with the corresponding graphics in the standard system vision system, the performance of each unit in the flight simulator vision system can be accurately tracked and compared with the standard. This helps to quickly locate which unit geometry data exceeds the allowable error range, thereby improving detection efficiency and accuracy. In addition, this identification method is conducive to data management and analysis, so that specific units can be adjusted in a targeted manner during subsequent calibration and maintenance work to ensure the accuracy and reliability of the entire vision system. At the same time, it is also convenient for automated processing and comparison, reducing the possibility and error rate of manual intervention.

[0094] In the present invention, the angle data classified to meet the tolerance and / or exceed the tolerance are output as a visual image, specifically:

[0095] A coordinate system is established in the image of the standard system vision system, wherein the horizontal coordinate of the coordinate system is the horizontal field of view, and the vertical coordinate is the vertical field of view; wherein the angle range of the horizontal field of view is greater than the angle range of the horizontal field of view in the image of the flight simulator vision system; the angle range of the vertical field of view is greater than the angle range of the vertical field of view in the image of the flight simulator vision system; taking a vision system with a horizontal field of view of 200 degrees and a vertical field of view of 40 degrees as an example, the coordinate system range can be set to a horizontal scale of 210 and a vertical scale of 50. The center is the 0 point, and the centers of the horizontal field of view and the vertical field of view are also located at this point;

[0096] The item identifiers in the standard system vision system are matched one by one with the scales of the coordinate system to form a geometric figure view of the standard vision system;

[0097] The geometric figures corresponding to the angle data that meets the tolerance and / or exceeds the tolerance are mapped in the geometric figure view of the standard vision system based on the entry identification, and are color-coded to obtain a visualization image.

[0098] Among them, the horizontal field of view is the horizontal direction, and the vertical field of view is the vertical direction.

They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of the present invention.
