[0049] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] To better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0051] The main solution of the embodiments of the present application is: determining the first baseline parameter obtained by the dual optical sight based on a preset zeroing point in the visible light mode; calculating the second baseline parameter in the thermal imaging mode according to the first baseline parameter and a preset baseline difference; determining the ballistic impact point in the thermal imaging mode based on the position parameter of the zeroing point, the baseline difference, and a preset visible light drop model in the visible light mode; and displaying the impact point position in the thermal imaging screen of the dual optical sight according to the ballistic impact point and the second baseline parameter.

[0052] As an advanced device that combines two aiming methods of visible light and thermal imaging, the dual optical digital sight is widely used in military, hunting and other fields.

[0053] The current dual optical digital sights mainly calculate and adjust the aiming point through ballistic algorithms to meet the shooting requirements under different environments and conditions. In the visible light and thermal imaging modes, the sight will calculate the dropped values respectively and adjust the aiming point accordingly. Due to the different imaging principles and characteristics of visible light and thermal imaging, the target points aimed by the sight in the two modes are inconsistent. Moreover, when switching the main screen, due to the difference in the aiming points in the two modes, serious deviation will occur in aiming, which affects the accuracy of the sight.

[0054] Therefore, how to improve the accuracy of the dual optical sight has become an urgent problem to be solved in this field.

[0055] In view of the above problems, the present application provides a calibration method for a dual optical sight. When the dual optical sight of the present application performs zeroing point calibration operation, it first obtains the first baseline parameter based on the zeroing point in the visible light mode, and then according to the preset baseline difference and the obtained first baseline parameter, the second baseline parameter in the thermal imaging mode can be calculated. Then, substituting the position parameter of the zeroing point and the baseline difference into the visible light drop model in the visible light mode, the ballistic impact point in the thermal imaging mode can be calculated. By displaying the impact point position according to the ballistic impact point and the second baseline parameter in the thermal imaging mode, the user can aim in the thermal imaging mode.

[0056] In summary, after determining the first baseline parameter in the visible light mode, the present application can calculate the impact point position in the thermal imaging mode based on the built-in baseline difference, zeroing point, and drop model, thereby avoiding the deviation problem of inconsistent target impact points in the two modes and improving the accuracy of the dual optical sight.

[0057] In this embodiment, for the convenience of description, the following uses a dual-optical sight as the execution subject to illustrate this embodiment and the following embodiments.

[0058] Based on this, the embodiments of the present application provide a calibration method for a dual-optical sight. Refer to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the calibration method for the dual-optical sight of the present application.

[0059] In this embodiment, the calibration method for the dual-optical sight includes steps S10 to S40:

[0060] Step S10, determining a first baseline parameter obtained by the dual-optical sight in the visible light mode based on a preset zeroing point;

[0061] It should be noted that in this embodiment, visible light zeroing and thermal imaging zeroing refer to the process of adjusting the aiming point of the sight to completely coincide with the weapon's impact point within a certain distance. This process is mainly to ensure that the weapon can accurately hit the target at a predetermined distance and determine the angle between the weapon and the sight in ballistic calculation. The baseline parameters include: baseline height, which represents the distance between the center points of the mirror surface or the barrel circular section.

[0062] In this embodiment, in the visible light mode of the dual-optical sight, first, a preset zeroing point is set, and the zeroing point is used to calibrate the sight. Subsequently, through the sensors or measuring devices inside the sight, the first baseline parameter corresponding to the zeroing point is obtained.

[0063] Step S20, calculating a second baseline parameter in the thermal imaging mode according to the first baseline parameter and a preset baseline difference;

[0064] In this embodiment, according to the obtained first baseline parameter and a preset baseline difference (this difference usually reflects the aiming point offset caused by factors such as wavelength and refraction between the visible light mode and the thermal imaging mode), calculations are performed to obtain the second baseline parameter in the thermal imaging mode.

[0065] Furthermore, in a feasible implementation manner, before the above step S20, the method may further include steps A10 to A30:

[0066] Step A10, measuring the lens optical axis distance between the visible light mode and the thermal imaging mode of the dual-optical sight;

[0067] In this embodiment, precise measuring tools and techniques are used to accurately measure the lens optical axes of the visible light mode and the thermal imaging mode of the dual-optical sight to determine the distance between them.

[0068] Step A20: Based on the optical axis spacing, barrel structure parameters, and lens distortion parameters, establish a double optical baseline difference comparison table;

[0069] In this embodiment, based on the known optical axis spacing of the lens, barrel structure parameters (such as barrel length, diameter, etc.), and lens distortion parameters (such as distortion coefficient, aberration, etc.), a mathematical model and calculation method are used to establish a double optical baseline difference comparison table. This comparison table reflects the corresponding relationship between the baseline differences between the visible light mode and the thermal imaging mode at different distances and angles.

[0070] Step A30: Encode and store the double optical baseline difference comparison table into the sight firmware.

[0071] In this embodiment, the established double optical baseline difference comparison table is encoded and then stored in the firmware of the double optical sight. When the sight is working, the required baseline difference information can be quickly obtained by reading the comparison table data in the firmware.

[0072] Step S30: Based on the position parameters of the zeroing point, the baseline difference, and the preset visible light drop model in the visible light mode, determine the ballistic impact point in the thermal imaging mode;

[0073] In this embodiment, the position parameters of the zeroing point (such as coordinates, height, etc.), the baseline difference, and the preset bullet drop model in the visible light mode (this model considers the influence of various factors such as wind speed, gravity, and bullet type on the bullet flight trajectory) are used for calculation to predict the ballistic impact point in the thermal imaging mode.

[0074] Further, in a feasible implementation manner, the above step S30 may include steps S31 to S33:

[0075] Step S31: Obtain the target point distance parameter through a preset distance sensor;

[0076] In this embodiment, a double optical sight or a preset distance sensor supporting it is used to measure and obtain the straight-line distance parameter between the target point and the shooter.

[0077] Step S32: Calculate the fixed drop value of the double optical sight at the zeroing point in the thermal imaging mode based on the zeroing point distance of the zeroing point, the target point distance parameter, and the baseline difference;

[0078] In this embodiment, based on the known zeroing point distance (i.e., the preset distance between the zeroing point and the shooter), the target point distance parameter, and the baseline difference (the difference between visible light zeroing and thermal imaging zeroing), using the principles of ballistics and relevant mathematical models, the fixed drop value of the bullet starting from the zeroing point when reaching the target point in the thermal imaging mode is calculated. This drop value reflects the falling distance of the bullet during flight due to factors such as gravity.

[0079] Step S33, determine the ballistic impact point in the thermal imaging mode based on the fixed drop value, the distance from the zeroing point to the target point distance parameter, and the baseline difference.

[0080] In this embodiment, based on the known fixed drop value, the distance parameter from the zeroing point to the target point, and the baseline difference, using the principles of ballistics and relevant mathematical models, the ballistic impact point of the bullet at the target point after starting from the zeroing point in the thermal imaging mode is further calculated. This ballistic impact point is the position where the shooter expects the bullet to hit.

[0081] Exemplarily, to facilitate understanding of the implementation process of the dual - optical sight calibration method obtained by combining this embodiment with the above - mentioned Embodiment 1, please refer to Figure 2 , Figure 2 A brief flow schematic diagram of a dual - optical sight calibration method is provided. Specifically:

[0082] When the dual - optical sight leaves the factory, the baseline height of the dual - optical lens is built - in. Based on the structural parameters and lens parameter characteristics of the visible light and thermal imaging products of the dual - optical sight, a dual - optical calculation model for calculating the thermal imaging drop by calculating the visible light drop based on ballistics is established; after the user installs the dual - optical digital sight and performs the dual - optical zeroing operation, the visible light baseline height parameter is measured and filled into the ballistic calculation. The uncertainty factors of the structural design, processing, and lens parameters are converted into determined values through the user's zeroing parameters. When the user uses it, after ranging, the ballistic calculation is directly performed. When the user uses it, based on the parameter value of the visible light, the drop value of the thermal imaging is solved by converting it into trigonometric functions. For the ballistic impact point of the visible light in the ballistic calculation, the dual - optical algorithm will calculate the thermal imaging drop value by combining the visible light drop data with the built - in baseline difference and zeroing point parameters, and the solved value is converted into the screen pixel position through the fixed pixel mil conversion relationship of the product. A dual - optical calculation model for calculating the thermal imaging drop by calculating the visible light drop based on ballistics is established, so that the impact points of the visible light aiming and the thermal imaging aiming are consistent.

[0083] Specifically, for the dual - optical calculation model, please refer to Figure 3 , in the figure, point a represents visible light; point b represents thermal imaging; point z represents the zeroing point; point f represents the calculated actual target point; ae represents the zeroing point distance; ag represents the target point distance; h represents the baseline difference height between visible light and thermal imaging;

[0084] As Figure 3 shown The corresponding falling value of the thermal imaging can be obtained through the point z and dc of the first zeroing.

[0085] Step S40: Display the landing position in the thermal imaging screen of the dual optical sight according to the ballistic landing point and the second baseline parameter.

[0086] In this embodiment, according to the calculated ballistic landing point coordinates, combined with the obtained second baseline parameter, through the thermal imaging display system of the dual optical sight, the landing position is accurately marked in the thermal imaging screen. In this way, the shooter can directly see the expected bullet landing point in the thermal imaging screen of the sight.

[0087] Further, in a feasible implementation manner, the above step S40 may further include steps S41 to S43:

[0088] Step S41: Calculate the pixel offset corresponding to the ballistic drop according to the target point distance parameter and the ballistic landing point;

[0089] In this embodiment, using the target point distance parameter and the ballistic landing point, combined with the resolution and zoom ratio of the thermal imaging screen of the dual optical sight, the pixel offset corresponding to the ballistic drop on the thermal imaging screen is calculated. This offset reflects the actual performance of the bullet drop on the screen. By calculating the pixel offset, the physical phenomenon of ballistic drop can be converted into a specific pixel position on the thermal imaging screen.

[0090] Step S42: Superimpose and display a dynamic aiming mark in the thermal imaging screen of the dual optical sight, where the dynamic aiming mark is used to represent the landing position;

[0091] In this embodiment, in the thermal imaging screen of the dual optical sight, a dynamic aiming mark is superimposed and displayed. This mark is used to represent the position of the ballistic landing point. The mark can be a point, a crosshair or other shapes, and the specific shape and size can be adjusted according to actual needs.

[0092] By superimposing and displaying the dynamic aiming mark, the shooter can intuitively see the position of the ballistic landing point on the thermal imaging screen, making it easier to aim and shoot.

[0093] Step S43: Real-time adjust the mark position to keep spatial consistency with the aiming point in the visible light mode.

[0094] In this embodiment, while displaying the dynamic aiming mark, according to the baseline difference between the visible light mode and the thermal imaging mode of the dual-optical aiming scope, as well as factors such as possible screen zooming and rotation, etc., the position of the mark is adjusted in real time to keep it spatially consistent with the aiming point in the visible light mode. This means that no matter which mode the shooter switches to, the aiming point should be at the same position.

[0095] By adjusting the mark position in real time, the consistency of the aiming point of the dual-optical aiming scope in different modes is ensured. This step eliminates the problem of aiming point deviation caused by mode switching, improving the operation convenience and shooting accuracy of the shooter.

[0096] Based on the first embodiment of the present application, in the second embodiment of the present application, for the content that is the same as or similar to the above-mentioned embodiment one, reference can be made to the above introduction and will not be elaborated hereinafter. On this basis, the dual-optical aiming scope calibration method further includes steps B10 to B30:

[0097] Step B10, detecting the ambient temperature through a temperature sensor;

[0098] In this embodiment, the temperature sensor built-in or external to the dual-optical aiming scope will detect the temperature of the surrounding environment in real time.

[0099] Step B20, when the ambient temperature does not match the preset temperature range, obtaining the temperature reading of the thermal imaging sensor;

[0100] In this embodiment, when it is detected that the ambient temperature does not match the preset suitable operating temperature range, the system will automatically obtain the temperature reading of the thermal imaging sensor, and this reading reflects the current temperature state of the thermal imaging module.

[0101] Step B30, adjusting the baseline difference based on the preset temperature-deformation mapping relationship.

[0102] In this embodiment, after obtaining the temperature reading of the thermal imaging sensor, according to the preset temperature-deformation mapping relationship (this mapping relationship is usually obtained through experiments or simulations and reflects the corresponding relationship between temperature changes and the baseline difference), the baseline difference is adjusted accordingly. This adjustment process aims to compensate for the influence of temperature changes on the performance of the dual-optical aiming scope and ensure high aiming accuracy at different temperatures.

[0103] By detecting the ambient temperature in real time, obtaining the temperature reading of the thermal imaging sensor, and adjusting the baseline difference based on the temperature-deformation mapping relationship, it can be ensured that the dual-optical aiming scope can maintain high aiming accuracy and stability at different ambient temperatures.

[0104] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the content that is the same as or similar to the above-mentioned first embodiment and / or the second embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, the dual-optical sight calibration method further includes steps C10 to C20:

[0105] Step C10, when detecting a thermal imaging mode activation signal, obtain the ambient light intensity;

[0106] In this embodiment, during the operation of the dual-optical sight, when the system detects a thermal imaging mode activation signal sent by the user or an automatic mechanism, it will immediately activate the ambient light intensity detection function, which is realized by a built-in light sensor and can measure and obtain the current ambient light intensity data in real time.

[0107] Step C20, switch to the thermal imaging mode when the ambient light intensity is lower than a preset threshold.

[0108] In this embodiment, after obtaining the ambient light intensity data, the system will compare it with a preset light intensity threshold, which is set according to the design and use environment of the dual-optical sight and represents a critical point of relatively low light intensity. If the ambient light intensity is lower than this threshold, the system will automatically switch the dual-optical sight to the thermal imaging mode.

[0109] By detecting the ambient light intensity in real time and making an intelligent judgment according to the preset threshold, the dual-optical sight can automatically select the most suitable aiming mode under different light conditions, improving the adaptability and practicality of the dual-optical sight and providing a more convenient and accurate aiming experience for shooters.

[0110] It should be noted that the above examples are only for understanding the present application and do not constitute a limitation to the dual-optical sight calibration method of the present application. Based on this technical concept, more forms of simple transformations are within the protection scope of the present application.
