Description

Technical Field

[0001] This invention relates to the field of weaponry technology, and in particular to a ballistic compensation method and device. Background Technology

[0002] Currently, for naked-eye sights or optical sights, mechanical sights are typically used for ballistic compensation. Different sights have specific mechanical sights; that is, the mechanical sight is usually calibrated during the design and manufacturing process based on the performance of the firearm and the ammunition used, resulting in a mechanical sight that is adjustable according to the target distance. During use, the shooter adjusts the position of the mechanical sight according to the estimated distance to achieve ballistic compensation.

[0003] However, in actual use, even ammunition of the same caliber can exhibit performance differences that lead to variations in ballistic compensation at longer distances. Existing mechanical sights cannot be flexibly adjusted to accommodate different ammunition types. To address this issue, mil-dots were added to optical sights and early digital sights to assist shooters in estimating target distances and calculating ballistic compensation based on the deviation between the point of impact and the aiming point. However, this method places high demands on the shooter's experience, memory, and ability to quickly estimate distances, making it quite inconvenient to use during actual firing.

[0004] Furthermore, fixed-position mil-dot gradations suffer from limited adaptability and inconvenience in use; while digital sights offer a degree of versatility, applicable to various firearms and ammunition types, installation deviations are possible during their setup. Therefore, existing ballistic compensation schemes all suffer from inconvenience and significant compensation errors. Summary of the Invention

[0044] The ballistic compensation method and apparatus proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clarify the explanation of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structures. In particular, different figures may emphasize different aspects and sometimes use different scales.

[0045] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish similar objects in order to describe embodiments of the invention, and are not used to describe a specific order or sequence. It should be understood that such uses of terminology are interchangeable where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0046] This embodiment provides a ballistic compensation method, such as Figure 1 As shown, it includes:

[0047] S1, assembling a composite sight onto a firearm;

[0048] S2, calibrate the composite sight to obtain calibration data;

[0049] S3, obtain the distance to the shooting target;

[0050] S4: Obtain the aiming point position based on the target distance and calibration data;

[0051] S5 makes firing decisions based on the aiming point position.

[0052] The ballistic compensation method provided in this embodiment calibrates the composite sight and obtains the aiming point position based on the target distance, enabling shooting decisions to be made based on the aiming point position during shooting. This not only simplifies the ballistic compensation operation during shooting but also effectively improves the accuracy of ballistic compensation, solving the problems of inconvenience and large compensation deviation in existing ballistic compensation schemes.

[0053] Specifically, since the firearm has an objective lens optical system and an eyepiece optical system, in order to make the aiming point position provided by the composite sight easily obtainable by the shooter, in this embodiment, step S1, the method of assembling the composite sight onto the firearm, includes:

[0054] S11, assembled composite sight.

[0055] Specifically, in this embodiment, the method for assembling the composite sight includes: first, connecting the image sensor, display device, and rangefinder to the main control board of the sight; preferably, also connecting devices such as an attitude sensor to the main control board of the sight; then, setting an image sensor at the imaging end of the objective lens optical system to acquire the image obtained by the objective lens optical system; preferably, the image sensor also has a digital scale, thereby enabling the calibration of reference points and baselines based on the image obtained by the objective lens optical system; and finally, setting a display device at the image end of the eyepiece optical system so that the eyepiece optical system displays the image displayed on the display device.

[0056] S12, fix the assembled composite sight onto the firearm.

[0057] In this way, the aiming point position displayed on the display device can be superimposed on the original image presented by the objective lens optical system and the eyepiece optical system, thereby facilitating the shooter's shooting decision.

[0058] The main control board of the sight is used to automatically calculate the aiming point position based on the image obtained by the image sensor and the distance to the shooting target obtained by the rangefinder. Therefore, in order for the main control board of the sight to provide an accurate aiming point position, it needs to be calibrated.

[0059] In this embodiment, as Figure 2 As shown, step S2, calibrating the composite sight to obtain calibration data, includes the following methods:

[0060] S21, calibrate the reference point of the composite sight to obtain reference point calibration data.

[0061] Specifically, in this embodiment, the method for calibrating the reference point roughly includes: First, setting an initial firing distance as the firing reference point. To ensure the calibration accuracy of the reference point, in this embodiment, the initial firing distance is no greater than 120 meters, for example, it can be 50 meters or 100 meters; then, fixing the firearm and completing the firing, which is equivalent to blind firing, the purpose of which is to find the difference between the current aiming point and the actual bullet impact point; finally, moving the reference point of the composite sight to the center position of the bullet impact point in the display device to obtain the calibrated reference point position. In this way, in subsequent firing, the calibrated reference point calibration data can be used to compensate for the difference between aiming and firing in the firing system composed of the firearm and the composite sight, thereby effectively improving the firing accuracy.

[0062] S22, calibrate the baseline of the composite sight to obtain baseline calibration data.

[0063] Specifically, in this embodiment, before baseline calibration, it is necessary to confirm whether it is a new combination of firearms and ammunition. If the combination of firearms and ammunition has already been used, that is, baseline calibration data corresponding to the combination definitely exists, the existing baseline calibration data can be directly loaded, thereby saving the calibration process. If the combination of firearms and ammunition has not been used before, then in order to improve shooting accuracy, the combination needs to be calibrated.

[0064] The method for calibrating the baseline generally includes the following steps: First, based on the shooting reference point, gradually increase the shooting distance according to a preset rule, for example, increasing the shooting distance by 20 meters each time; then, after each increase in shooting distance, fix the firearm to complete the firing, and move the baseline of the composite sight to the center position of the bullet impact point in the display device to obtain the calibrated baseline position; finally, bind the baseline position obtained each time with the shooting distance to obtain multiple sets of bound data, which is the baseline calibration data.

[0065] S23, save the benchmark calibration data and baseline calibration data.

[0066] Specifically, after the calibration data is saved, the composite sight is activated, that is, the digital sight is activated, so that actual shooting can be carried out based on the calibration data.

[0067] Furthermore, in this embodiment, step S3, the method for obtaining the distance to the shooting target, includes:

[0068] S31, the distance between the firearm and the target is measured by the rangefinder of the composite sight.

[0069] In practical applications, the ranging device can be a photoelectric rangefinder or other device with remote ranging function, and this application does not limit this.

[0070] S32, the rangefinder sends the measured target distance to the main control board of the sight.

[0071] Preferably, considering the situation of moving targets or multiple targets, the distance to the target may change. Therefore, in order to improve the accuracy and real-time performance of ballistic compensation, in this embodiment, the main control board of the sight controls the rangefinder to measure the distance to the target at preset time intervals, such as at 5-second intervals. The distances of the most recent targets are retained, so that the main control board of the sight can calculate the target's direction of movement, speed and other information based on the most recently retained target distances. In this way, the ballistic compensation can be adjusted in real time according to the direction of movement and speed, thereby ensuring shooting accuracy.

[0072] Furthermore, in this embodiment, step S4, the method for obtaining the aiming point position based on the target distance and calibration data, includes:

[0073] S41, the main control board of the sight calculates the ballistic compensation amount based on the target distance provided by the rangefinder and the pre-stored calibration data;

[0074] S42, the main control board of the sight processes the ballistic compensation amount and the image provided by the image sensor to obtain the position of the aiming point in the image, that is, the aiming point position;

[0075] S43 overlays the aiming point position onto the target image (the original acquired image) and highlights it, allowing the shooter to obtain the aiming point position while acquiring the shooting range image through the eyepiece optical system, thereby effectively improving shooting accuracy.

[0076] Preferably, in the case of moving targets and multiple targets, the ballistic compensation amount corresponding to the distance of each target is obtained based on the distance and calibration data of each target; then the aiming point position is obtained based on each ballistic compensation amount; finally, all aiming point positions are displayed on the display device.

[0077] Furthermore, in this embodiment, step S5, the method for making shooting decisions based on the aiming point position, includes adjusting the angle of the firearm according to the aiming point position and the actual shooting target, so that the final bullet impact point is the aiming point during shooting, thereby effectively improving shooting accuracy. This method can achieve high-precision shooting without requiring the shooter to have high shooting skills or experience.

[0078] In practical applications, ballistic compensation can be started and stopped by buttons or software. Alternatively, an attitude sensor can be installed in the composite sight to identify the occurrence of a specific attitude and start or stop ranging and ballistic compensation.

[0079] In one specific embodiment, a typical and practical approach is to identify the roll motion of the composite sight during use. If the composite sight rolls within a preset period, and the roll exceeds a preset angle before returning to center, then ranging and ballistic compensation are activated. For example, if the roll exceeds 30° within a short period and then returns to center, ranging and ballistic compensation are activated, or ranging and ballistic compensation are stopped. This embodiment uses an attitude sensor to activate or deactivate ranging and automatic ballistic compensation functions with minimal operational overhead and without significantly affecting continuous aiming, thus greatly improving the practicality of the ranging function while ensuring device battery life.

[0080] This embodiment also provides a ballistic compensation device for implementing the ballistic compensation method described above, such as... Figure 3 As shown, the ballistic compensation device includes a composite sight and a firearm; the composite sight is fixed to the firearm; the composite sight includes an image sensor, a display device, a rangefinder, a main control board objective lens optical system, and an eyepiece optical system; the image sensor, the display device, and the rangefinder are communicatively connected to the main control board; the image sensor is located at the imaging end of the objective lens optical system to acquire the image obtained by the objective lens optical system; the display device is located at the image end of the eyepiece optical system to enable the eyepiece optical system to display the image displayed on the display device.

[0081] The ballistic compensation device provided in this embodiment can be calibrated according to different combinations of firearms and ammunition, and automatically calculate the aiming point position using the calibrated data and the actual target distance during actual shooting. This allows shooting decisions to be made based on the aiming point position, which not only simplifies the ballistic compensation operation during shooting, but also effectively improves the accuracy of ballistic compensation, solving the problems of inconvenience and large compensation deviation in existing ballistic compensation schemes.

[0082] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. In addition, different parts between embodiments can also be combined with each other, and this invention does not limit this.
