[0048] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] In this embodiment, for the convenience of description, the following is described with an electronic sight equipped with an encoder, or a mobile terminal, a data storage control terminal, a PC (Personal Computer) and other terminals connected to an electronic control unit supporting the electronic sight as the execution subject. It should be noted that in this embodiment and another embodiment, night vision devices, thermal imaging sights, thermal imagers, thermal imaging searchers, thermal imaging and visible light dual-light sights, binocular searchers and other devices can also be used as the execution subject.

[0051] Based on the above-mentioned sight, the overall concept of the aiming mark updating method of the present application is proposed here.

[0052] With the continuous development of photoelectric sensors, traditional optical sights have gradually evolved in the direction of digitalization and intelligence, and have significantly improved the shooting accuracy at medium and long distances through real-time ballistic calculation and standard mark correction functions. In related technologies, in order to meet users' demand for shooting accuracy, technicians usually integrate laser ranging modules on the sights, so as to accurately obtain the actual distance between the shooting target and the user through the laser ranging module, and then calculate the trajectory drop point based on the actual distance. However, due to the high manufacturing cost of the laser ranging module, the overall cost, volume, power consumption and other parameters of the sight have increased significantly, making it difficult to meet users' rigid demand for lightweight and low power consumption equipment.

[0053] In view of the above phenomena, the present application provides a method for updating aiming marks. The method for updating aiming marks includes: obtaining a zeroing calibration distance and receiving a user's estimated distance input by the user; determining zeroing calibration parameters corresponding to the zeroing calibration distance, and calculating a first ballistic drop distance based on the zeroing calibration parameters and the user's estimated distance; obtaining a first updated aiming mark based on the first ballistic drop distance and an initial aiming mark on the display screen of the aiming scope, and controlling the display screen to play the first updated aiming mark.

[0054] In this way, the present application solves the technical problem that the aiming scope in the related art is difficult to meet the rigid requirements of users for device light weight and low power consumption. That is, the present application receives the user's estimated distance input by the user, and calculates the ballistic drop distance based on the user's estimated distance and the zeroing calibration distance, so as to update the aiming mark matching the ballistic drop distance on the display screen of the aiming scope. In this way, without configuring a laser rangefinder module on the aiming scope, the ballistic calculation operation can be quickly completed, thereby significantly reducing the device cost and power consumption of the aiming scope.

[0055] Based on the overall concept of the aiming mark updating method of the present application, an embodiment of the present application provides an aiming mark updating method. Refer to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the aiming mark updating method of the present application. In this embodiment, the aiming mark updating method includes steps S10 to S30:

[0056] Step S10: Obtain a zeroing calibration distance and receive a user's estimated distance input by the user;

[0057] Step S20: Determine zeroing calibration parameters corresponding to the zeroing calibration distance, and calculate a first ballistic drop distance based on the zeroing calibration parameters and the user's estimated distance;

[0058] Step S30: Obtain a first updated aiming mark based on the first ballistic drop distance and an initial aiming mark on the display screen of the aiming scope, and control the display screen to play the first updated aiming mark.

[0059] It should be noted that the zeroing calibration distance is the basic distance used to calibrate the aiming mark. It can be understood that at the zeroing calibration distance, the aiming mark coincides with the actual impact point of the bullet. In addition, the user's estimated distance is the distance value manually input by the user. In addition, the first ballistic drop distance is the vertical drop amount of the bullet obtained based on the zeroing calibration parameters and the user's estimated distance. In addition, the initial aiming mark is the default aiming mark obtained at the zeroing calibration distance (such as the center point of the crosshair). In addition, the first updated aiming mark is a new aiming mark generated after determining the ballistic drop distance, which is used to assist the user in aiming during the actual shooting process.

[0060] In this embodiment, when the sight is in operation, it first obtains the zeroing calibration distance. At the same time, the sight receives the user estimated distance input by the user through the encoder configured by itself. Thereafter, the sight inputs the zeroing calibration distance to the encoder, and the encoder processes the zeroing calibration distance to determine the zeroing calibration parameters such as the initial velocity of the bullet, the barrel angle, the resistance function, the resistance coefficient, etc. contained in the zeroing calibration distance, and iterates according to each zeroing calibration parameter and the user estimated distance to generate a ballistic trajectory that matches the user estimated distance, and then outputs the first ballistic drop distance based on the ballistic trajectory. Finally, the encoder determines the first pixel coordinates of the first updated aiming mark on the display screen based on the initial aiming mark and the first ballistic drop distance displayed on the display screen, and controls the display screen based on the first pixel coordinates to display the first updated aiming mark corresponding to the first ballistic drop distance on the display screen.

[0061] For example, see Figure 2 , Figure 2 This is a schematic diagram of an aiming mark involved in an embodiment of the aiming mark updating method of the present application. When the aiming scope is running, it first reads the storage module to obtain the zero calibration distance stored when shooting at a fixed distance target under a standard environment. At the same time, the aiming scope detects the encoder configured by itself to receive the user estimated distance x input by the user through the encoder. target After that, the sight inputs the zero calibration distance into the encoder, and the encoder reads the storage module to obtain the barrel elevation angle θ and the initial bullet velocity V generated at the zero calibration distance. i , drag function drag_function, drag coefficient drag_coefficient and other zero calibration parameters, and perform trajectory iterative calculation based on the zero calibration parameters to iteratively calculate the bullet displacement according to the time step dt until the cumulative horizontal displacement of the bullet is x 1 Reach user estimated distance x target , based on the cumulative horizontal displacement x of the bullet 1 The corresponding cumulative vertical displacement y of the bullet 1 Determined as the first trajectory falling distance y 1 Finally, the encoder is based on the first trajectory falling distance y 1 and the initial pixel coordinates corresponding to the initial aiming mark on the display screen, determine the first pixel coordinates corresponding to the first updated aiming mark corresponding to the first trajectory falling distance, and the encoder further controls the display screen according to the first pixel coordinates to display the following on the display screen: Figure 2 A first updated aiming mark is shown.

[0062] In this way, the present application solves the technical problem in the related art that it is difficult for sights to meet the rigid requirements of users for lightweight and low power consumption of the device. That is, the present application receives the user estimated distance input by the user, and calculates the ballistic drop distance based on the user estimated distance and the zeroing calibration distance, thereby updating the aiming mark that matches the ballistic drop distance on the display screen of the sight. This method can quickly complete the ballistic calculation operation without the need to configure a laser ranging module in the sight, thereby significantly reducing the equipment cost and power consumption of the sight.

[0063] In a feasible implementation manner, the step of "calculating the first trajectory falling distance based on the zeroing calibration parameter and the user estimated distance" in the above step S20 may specifically include steps S201 to S206:

[0064] Step S201: reading the initial velocity of the bullet, the barrel elevation angle, the preset gravity acceleration, the preset resistance coefficient, the preset resistance function and the initial displacement of the bullet contained in the zeroing calibration parameters;

[0065] Step S202: Calculating the bullet's horizontal initial velocity and the bullet's vertical initial velocity based on the gun barrel elevation angle and the bullet's initial velocity, and calculating the horizontal gravity influence parameter and the vertical gravity influence parameter based on the preset gravity acceleration and the gun barrel elevation angle;

[0066] Step S203: Calculating a reduction in the horizontal velocity of the bullet and a reduction in the vertical velocity of the bullet based on the preset resistance coefficient, the preset resistance function, the initial horizontal velocity of the bullet and the initial vertical velocity of the bullet;

[0067] Step S204: determining the bullet horizontal speed update amount according to the bullet horizontal speed reduction amount, and determining the bullet vertical speed update amount according to the bullet vertical speed reduction amount;

[0068] Step S205: dynamically iteratively updating the initial displacement of the bullet based on the updated horizontal velocity of the bullet to obtain an updated horizontal displacement of the bullet, and dynamically iteratively updating the initial displacement of the bullet based on the updated vertical velocity of the bullet to obtain an updated vertical displacement of the bullet;

[0069] Step S206: When it is detected that the bullet horizontal displacement update amount reaches the user estimated distance, the first trajectory falling distance is determined based on the bullet vertical displacement update amount.

[0070] It should be noted that the initial horizontal velocity of the bullet v x (0) is the initial velocity component of the bullet in the horizontal direction of the barrel axis, which is the initial velocity V of the bullet during the zero calibration operation. i And the barrel elevation angle θ is calculated. Similarly, the vertical initial velocity v of the bullet y(0) is the initial velocity component of the bullet in the direction perpendicular to the barrel axis, which is calculated from the initial velocity V of the bullet during the zeroing calibration operation i and the elevation angle θ of the barrel. In addition, the initial displacement x of the bullet 0 is the initial displacement value for recursive calculation, and by default, x = 0, y = 0, which is used to indicate that the bullet starts to move from the muzzle position.

[0071] Exemplarily, for example, the encoder reads the elevation angle θ of the barrel, the initial velocity V of the bullet i , the drag function drag_function, the drag coefficient drag_coefficient, the preset gravitational acceleration Gravity, and the initial displacement x of the bullet 0 . After that, the encoder calculates the horizontal initial velocity v of the bullet i based on the elevation angle θ of the barrel and the initial velocity V of the bullet x (0):

[0072] v x (0) = V i cos(θ);

[0073] And, based on the elevation angle θ of the barrel and the initial velocity V of the bullet i calculates the vertical initial velocity v of the bullet y (0):

[0074] v y (0) = V i sin(θ);

[0075] At the same time, the encoder calculates the horizontal gravity influence parameter G generated by gravity on the horizontal direction of the bullet based on the elevation angle θ of the barrel and the preset gravitational acceleration Gravity x :

[0076] G x = Gravitysin(θ);

[0077] And determines the vertical gravity influence parameter G generated by gravity on the vertical direction of the bullet y :

[0078] G y = Gravitycos(θ);

[0079] After that, the encoder calculates the velocity reduction dv caused by resistance based on the drag function drag_function and the drag coefficient drag_coefficient:

[0080] dv = retard(drag_function,drag_ceofficient,v);

[0081] The encoder thus determines the horizontal velocity reduction dv of the bullet in the horizontal direction based on the velocity reduction dv x :

[0082]

[0083] and, determine the vertical velocity reduction dv of the bullet in the vertical direction y :

[0084]

[0085] The encoder then reduces the amount dv according to the horizontal speed x and horizontal gravity influence parameter G x , calculate the bullet horizontal velocity update v x :

[0086] v x =v x (0)+dv x +G x ×dt;

[0087] and, according to the vertical velocity reduction dv y , vertical gravity influence parameter G y , calculate the updated vertical velocity v of the bullet y :

[0088] v y =v y (0)+dv y +G y ×dt;

[0089] The encoder thus updates the amount v according to the horizontal velocity of the bullet x Update the initial horizontal displacement of the bullet to obtain the updated horizontal displacement x of the bullet 1 :

[0090] x 1 =x 0 +v x ×dt;

[0091] And update the amount v according to the vertical velocity of the bullet y Update the initial vertical displacement of the bullet to get the updated vertical displacement y of the bullet 1 :

[0092] y 1 =y 0 +v y ×dt;

[0093] Finally, the encoder updates the bullet's horizontal displacement by x 1 Estimated distance x from the usertarget Compare and update the horizontal displacement x of the bullet 1 Reach user estimated distance x target In the case of 1 The corresponding bullet vertical displacement update y 1 , determined as the first ballistic falling distance.

[0094] In this way, the present application solves the technical problem in the related art that it is difficult for sights to meet the rigid requirements of users for lightweight and low power consumption of the device. That is, the present application receives the user estimated distance input by the user, and calculates the ballistic drop distance based on the user estimated distance and the zeroing calibration distance, thereby updating the aiming mark that matches the ballistic drop distance on the display screen of the sight. This method can quickly complete the ballistic calculation operation without the need to configure a laser ranging module in the sight, thereby significantly reducing the equipment cost and power consumption of the sight.

[0095] Based on the first embodiment of the present application, a second embodiment of the present application is proposed. In the second embodiment of the present application, the same or similar contents as those of the above embodiments can be referred to the above description and will not be described in detail later. Figure 3 , Figure 3 For xx, such as Figure 3 As shown, after the step of "determining the zeroing calibration parameter corresponding to the zeroing calibration distance" in the above step S20, the aiming mark updating method of the present application may further include steps A10 to A30:

[0096] Step A10: Detecting real-time environmental parameters corresponding to the sight;

[0097] Step A20: updating the zeroing calibration parameter based on the real-time environmental parameter to obtain an updated calibration parameter, and calculating a second trajectory falling distance according to the updated calibration parameter and the user estimated distance;

[0098] Step A30: obtaining a second updated aiming mark based on the second trajectory falling distance and the initial aiming mark, and controlling the display screen to play the second updated aiming mark.

[0099] It should be noted that the real-time environmental parameters are physical quantities of the shooting environment collected in real time by sensors, including but not limited to: temperature, air pressure, wind speed, air density, etc. It is understandable that the errors in the trajectory calculation process can be further corrected by the real-time environmental parameters. In addition, the second trajectory drop distance is the coordinate of the vertical drop amount of the trajectory that is calculated and matches the user's estimated distance during the trajectory calculation process corrected based on the environmental parameters.

[0100] For example, the encoder obtains the barrel elevation angle θ and the initial bullet velocity V corresponding to the zero distance parameter. i , drag function drag_function, drag coefficient drag_coefficient and other zero calibration parameters, the temperature and pressure sensor and wind speed sensor configured by itself can also be called to collect real-time temperature parameters and real-time wind pressure parameters in the environment where the sight is located, and calculate the air density parameters based on the real-time temperature parameters and real-time wind pressure parameters. After that, the encoder corrects the above-mentioned drag coefficient according to the air density parameter to obtain an updated drag coefficient, and calculates the second speed reduction according to the updated drag coefficient. The encoder further determines the second horizontal speed reduction of the bullet in the horizontal direction and the second vertical speed reduction of the bullet in the vertical direction based on the second speed reduction. The encoder further determines the second horizontal speed reduction based on the second horizontal speed reduction, the second vertical speed reduction, and the above-mentioned horizontal gravity influence parameter G x , the above vertical gravity influence parameter G y The second bullet horizontal speed update amount and the second bullet vertical speed update amount are calculated, and the initial vertical displacement of the bullet and the initial horizontal displacement of the bullet are calculated based on the second bullet horizontal speed update amount and the second bullet vertical speed update amount to obtain the second bullet horizontal displacement update amount x 2 and the second bullet's vertical displacement update y 2 , the encoder then detects the horizontal displacement update amount x of the second bullet 2 Reach user estimated distance x target In the case of , the horizontal displacement of the second bullet is updated by x 2 The corresponding second bullet vertical displacement update y 2 , determined as the second ballistic falling distance, and finally, the encoder determines the second pixel coordinates corresponding to the second updated aiming mark corresponding to the second ballistic falling distance based on the second ballistic falling distance and the initial pixel coordinates corresponding to the initial aiming mark on the display screen, and the encoder then controls the display screen according to the second pixel coordinates to display the second updated aiming mark on the display screen.

[0101] In this way, the sight can adaptively correct the trajectory calculation process according to environmental parameters, thereby further improving the accuracy of the trajectory calculation results.

[0102] Based on the first embodiment and / or the second embodiment of the present application, the third embodiment of the present application is proposed here. In the third embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be repeated later. On this basis, after the above step S10, the aiming mark update method of the present application can also include steps B10 to B20:

[0103] Step B10: querying a preset coordinate mapping table based on the user estimated distance to determine the target trajectory falling distance that matches the user estimated distance;

[0104] Step B20: obtaining a third updated aiming mark according to the target trajectory falling distance and the initial aiming mark, and controlling the display screen to play the third updated aiming mark.

[0105] For example, upon receiving the user estimated distance x input by the user, the encoder target Afterwards, the storage module configured in the sight can also be read to obtain a coordinate mapping MAP (table) containing multiple preset estimated distances and preset ballistic drop distances that match the multiple preset estimated distances, and based on the user's estimated distance x target Query the coordinate map MAP to determine the estimated distance x from the user target Matched target trajectory falling distance y 3 Finally, the encoder is based on the target trajectory falling distance y 3 The initial pixel coordinates corresponding to the initial aiming mark on the display screen determine the target trajectory falling distance y 3 The encoder controls the display screen according to the third pixel coordinates corresponding to the corresponding third updated aiming mark, so that the third updated aiming mark is displayed on the display screen.

[0106] In this way, the sight can quickly determine the ballistic drop distance that matches the estimated distance input by the user by querying the mapping table in a low computing power scenario, and then update the aiming mark based on the ballistic drop distance.

[0107] In a feasible implementation manner, the above step B10 may specifically include steps B101 to B103:

[0108] Step B101: obtaining a plurality of preset estimated distances and a preset trajectory falling distance that matches each of the plurality of preset estimated distances;

[0109] Step B102: comparing the user estimated distance with a plurality of preset estimated distances to determine a target estimated distance that is consistent with the user estimated distance;

[0110] Step B103: Determine the preset trajectory falling distance that matches the target estimated distance as the target trajectory falling distance that matches the user estimated distance.

[0111] It should be noted that the above-mentioned preset estimated distance is a discrete distance value (e.g., 100 meters, 200 meters, 300 meters) generated by the sight during the zero calibration stage. It can be understood that the preset estimated distance is used to quickly match the user estimated distance x input by the user. targetIn addition, the preset ballistic drop distance is the vertical drop amount bound to each preset estimated distance.

[0112] Exemplarily, for example, after the encoder receives the user's estimated distance x input by the user target it can also read the storage module configured in the sight to obtain a coordinate mapping MAP (table) containing multiple preset estimated distances and the preset ballistic drop distances respectively matched to the multiple preset estimated distances. After that, based on the user's estimated distance x target the encoder queries the coordinate mapping MAP to compare the user's estimated distance x target with the multiple preset estimated distances included in the coordinate mapping MAP respectively, so as to determine the target estimated distance that is consistent with the user's estimated distance x in the coordinate mapping MAP target Finally, the encoder reads the preset ballistic drop distance y matched by the target estimated distance in the coordinate mapping MAP 3 and determines the preset ballistic drop distance y matched by the target estimated distance 3 as the target ballistic drop distance y matched with the user's estimated distance x target 3

[0113] In this way, the sight can quickly determine the ballistic drop distance matched with the estimated distance input by the user by querying the mapping table in a low-computing-power scenario, and then update the aiming mark based on the ballistic drop distance.

[0114] Based on the embodiments of the present application, the fourth embodiment of the present application is proposed herein. In the fourth embodiment of the present application, for the same or similar content as the above embodiments, reference can be made to the above introduction and will not be repeated hereinafter. On this basis, after the above step S30, the aiming mark updating method of the present application may further include steps C10 to C20:

[0115] Step C10: Determine the aiming mark distance difference between the first updated aiming mark and the initial aiming mark;

[0116] Step C20: Determine multiple auxiliary aiming positions based on the aiming mark distance difference, and add respective corresponding auxiliary aiming marks at the multiple auxiliary aiming positions, wherein the colors of the auxiliary aiming marks are different.

[0117] ​​Exemplarily, for example, after determining the above-mentioned first updated aiming mark, the encoder can also compare the first updated aiming mark with the above-mentioned initial aiming mark to determine the aiming mark distance difference generated between the first updated aiming mark and the initial aiming mark. After that, the encoder divides the aiming mark distance difference according to a preset interval parameter to obtain multiple difference intervals, and sets an auxiliary aiming position in the middle position of each difference interval. The encoder then generates auxiliary aiming marks that match each auxiliary aiming position according to a preset color mapping rule and a warm color → cold color gradient (that is, warm colors are used for auxiliary points close to the initial aiming mark, and cold colors are used for auxiliary aiming marks far from the initial aiming mark). The encoder then controls the display screen to display each auxiliary aiming mark.

[0118] In this way, the scope can visualize the downward trend of the trajectory by constructing multiple auxiliary aiming representations, thereby helping users quickly understand the aiming correction amount at different distances.

[0119] This application also provides a device for updating the aiming mark, please refer to Figure 4 , the aiming mark updating device comprises:

[0120] The parameter receiving module 10 is used to obtain the zero calibration distance and receive the user estimated distance input by the user;

[0121] The trajectory calculation module 20 is used to determine the zero calibration parameter corresponding to the zero calibration distance, and calculate the first trajectory falling distance based on the zero calibration parameter and the user estimated distance;
