Description

Technical Field

[0001] This invention relates to a calibration method and its aiming device, and more particularly to a calibration method and its aiming device that can be used to calibrate the actual impact point of the firing device at different distances. Background Technology

[0002] In recent years, the use of shooting devices, such as crossbows and firearms, has become increasingly widespread. Among them, the crossbow is a shooting weapon evolved from the bow. Compared to the bow, because it does not require aiming while drawing the string, it places lower demands on the user's physical fitness and skills, making the crossbow increasingly popular in the market as a shooting device.

[0003] In the use of shooting devices, such as crossbows, calculating ballistic compensation at different distances has a significant impact on shooting accuracy. Generally, shooting devices are used in conjunction with scopes to increase aiming accuracy. Existing scopes for shooting devices typically have preset parameters for different types of arrows to roughly estimate the possible arrow's impact point. However, due to differences in the brand and type of shooting device, as well as user habits and preferences, scopes often fail to accurately indicate the impact point, causing user confusion and even raising questions about the quality of the scope and the shooting device itself. Summary of the Invention

[0004] In view of this, the present invention provides a calibration method and an aiming device thereof.

[0005] This invention discloses a calibration method. First, a first impact point is viewed using a display unit, where the distance from the first impact point to the firing device is a first distance. Based on the position of the first impact point displayed on the display unit, a first mark corresponding to the first impact point is marked on the display unit. After the first mark corresponding to the first impact point is completed, a second impact point is viewed through the display unit, where the distance from the second impact point to the firing device is a second distance. The first distance and the second distance are different. Based on the position of the second impact point displayed on the display unit, a second mark corresponding to the second impact point is marked on the display unit. Then, the impact point trajectory is calculated based on the first distance and the first mark corresponding to the first impact point, and the second distance and the second mark corresponding to the second impact point, and an impact point indication is given.

[0006] This invention discloses a calibration method. First, a plurality of impact points are examined using a display unit, wherein each impact point is at a specific distance from the firing device, and this specific distance is different for each impact point. Based on the position of each impact point as displayed on the display unit, a mark is made for each impact point on the display unit. Then, the impact point trajectory is calculated based on the specific distance of each impact point and the mark, and an impact point indication is given.

[0007] In some embodiments, each impact point is generated by the firing device performing the firing operation at a specific distance. The firing trajectory corresponding to the firing device is calculated by processing the first distance of the first impact point and the first mark with the second distance of the corresponding second impact point and the second mark. The firing trajectory is used to indicate the impact point in the aiming device during firing operations at different distances.

[0008] In some embodiments, marking the reticle for each landing point is done by displaying the first mark at the center or any position of the display unit. An instruction is received to adjust the position of the first mark until it moves to the first landing point in the display unit. The first landing point may be a mark formed by an arrow, bullet, or golf ball, or the position where the arrow, bullet, or golf ball itself stops.

[0009] In some embodiments, the firing trajectory of the corresponding firing device is obtained by linear fitting using a function based on a first distance corresponding to the first landing point and a second distance between the first marker and the second landing point and the second marker.

[0010] In some embodiments, the calibration method is applied to an aiming device, and the aiming device includes an objective lens unit facing the direction of the first impact point, a display unit for viewing the first impact point, and a control unit. The control unit includes a standard curve establishment mode and an impact point compensation shooting mode. According to an instruction, the aiming device is caused to enter the standard curve establishment mode or the impact point compensation shooting mode. In the standard curve establishment mode, the calibration method is performed to obtain the shooting trajectory, and in the impact point compensation shooting mode, the impact point is indicated according to the shooting trajectory. The shooting device includes a crossbow, and the aiming device is detachably fixed to the crossbow.

[0011] In some embodiments, the calibration method is applied to the aiming device, and the aiming device includes a ranging unit. The ranging unit includes a laser emitting unit and a laser receiving unit. The laser emitting unit emits a measurement beam, which passes through the objective lens unit toward the first point of impact, is reflected by the first point of impact to form a reflected beam, and the reflected beam then passes through the objective lens unit to reach the laser receiving unit, thereby obtaining the distance value of the first point of impact.

[0012] In some embodiments, the calibration method is applicable to the aiming device, and the aiming device includes a ranging unit. The ranging unit includes a laser emitting unit, a laser receiving unit, and a ranging objective lens unit. The laser emitting unit emits a measurement beam, which passes through the ranging objective lens unit and is directed towards the first point of impact. The beam is reflected by the first point of impact to form a reflected beam, which then passes through the objective lens unit or the ranging objective lens unit to reach the laser receiving unit, thereby obtaining the distance value of the first point of impact.

[0013] In some embodiments, the calibration method is applicable to the aiming device. The aiming device includes at least an eyepiece unit and a relay lens unit, wherein the objective lens unit and the eyepiece unit define a first optical axis, and the relay lens unit is disposed between the objective lens unit and the eyepiece unit. The objective lens unit has a first imaging surface, and the relay lens unit has a second optical axis and a second imaging surface, the second optical axis being movably parallel to the first optical axis. The laser emitting unit and the laser receiving unit are not located on the optical axis. The display unit is disposed on either the first imaging surface or the second imaging surface, and the display unit generates a light beam that is directed towards the eyepiece unit and propagates along the first optical axis, and the display unit can be viewed through the eyepiece unit.

[0014] In some embodiments, the calibration method is applied to the aiming device. The aiming device further includes performing a zeroing operation at a corresponding zeroing distance of the aiming device, wherein the zeroing distance is less than the first distance.

[0015] Therefore, the aiming device calibration method and aiming device of this application can mark the actual impact point in the display unit of the aiming device using reticles based on the actual impact point of the shooting device at different distances, and simulate the real shooting trajectory by linear fitting, thereby achieving an accurate impact point indication effect.

[0028] Figure 1 This invention displays an aiming device according to an embodiment of the present invention. The aiming device 100 according to an embodiment of the present invention includes at least a display unit 110, a storage unit 120, and a processing control unit 130. The display unit 110 can be used to display relevant information, such as relevant interfaces or text. Note that in some embodiments, the aiming device 100 can be a sight, which includes at least an objective lens unit and an eyepiece unit. The storage unit 120 can store relevant data required by the processing control unit 130 when performing the calibration method of the aiming device of this application. In some embodiments, the storage unit 120 can record the firing trajectory of the corresponding firing device generated by the processing control unit 130, the details of which will be described later. The processing control unit 130 can execute the calibration method of the aiming device of this application, the details of which will be described later.

[0029] It is worth noting that in some embodiments, the aiming device 100 can be detachably attached to a firing device, such as a pistol or crossbow. For example, Figure 2 This illustrates a shooting device and an aiming device according to embodiments of the present invention. For example... Figure 2 As shown, the shooting device is a crossbow 200, and the aiming device 100 can be detachably fixed to the crossbow 200.

[0030] Figure 3 This invention demonstrates a calibration method for an aiming device according to an embodiment of the present invention. The calibration method for an aiming device according to an embodiment of the present invention is applicable to, for example... Figure 1 The aiming device. It should be noted that the aiming device can be detachably attached to the firing device, such as a crossbow.

[0031] First, the shooting device is fixed in place, and as in step S310, multiple impact points are viewed through the display unit of the aiming device. It is important to note that each impact point is at a specific distance from the shooting device. It is worth noting that in some embodiments, each impact point may be generated by shooting at a target at that specific distance using the shooting device, and the specific distance for each impact point may be different. For example, in the case of three impact points, each impact point may be the actual impact point obtained by shooting at targets located at 30 yards, 50 yards, and 70 yards respectively. Furthermore, it must be noted that each impact point may be a mark formed by an arrow, bullet, or golf ball, or the position where the arrow, bullet, and / or golf ball itself stops. Next, as in step S320, based on the position of each impact point as displayed in the display unit, a reticle (or mark) is marked for each impact point in the display unit. Then, as in step S330, the shooting trajectory of the shooting device is calculated based on the specific distance of each impact point and the marked reticle / mark. It is worth noting that in some embodiments, the firing trajectory of the corresponding firing device can be obtained by linear fitting using a function-based approach, based on the specific distance of each impact point and the reticle / marker. It should be noted that linear fitting is a form of curve fitting. Assuming that x and y are observed quantities, and y is a function of x: y = f(x; b), curve fitting seeks the best estimate of parameter b using the observed values ​​of x and y, and thus seeks the optimal theoretical curve y = f(x; b). When the function y = f(x; b) is a linear function of b, this curve fitting is called linear fitting. In this application, the specific distance and the position of the reticle / marker are the observed quantities in a quadratic function. The obtained firing trajectory can be used to indicate the impact point in the aiming device during firing operations at different distances using this firing device.

[0032] It's important to note that most commercially available crossbow scopes rely on default arrow parameters to roughly estimate the arrow's landing point. Therefore, they are not very accurate in determining the actual arrow's trajectory, and the same scope cannot be universally compatible with multiple crossbows of different muzzle velocities (FPS). The scope utilizing the technology described in this application requires only one calibration upon initial use with the same FPS arrows. Based on at least three actual arrow landing points at different distances using the crossbow, an algorithm, combined with display reticle lines, simulates the real arrow trajectory. This allows for the calculation of the landing point at different distances when shooting with a crossbow, providing a more accurate arrow landing point indication during use.

[0033] Figure 4 This illustrates a calibration method for an aiming device according to another embodiment of the present invention. The calibration method for an aiming device according to an embodiment of the present invention is applicable to, for example... Figure 1 The aiming device. It should be noted that the aiming device can be detachably attached to the firing device, such as a crossbow. In this embodiment, the reticle lines for the corresponding impact points can be marked.

[0034] First, as in step S410, a zeroing operation is performed on the aiming device at the corresponding zeroing distance, where the zeroing distance is less than a specific distance for each landing point. Note that in some embodiments, the zeroing distance may be 20 yards. For each landing point, as in step S420, a reticle is displayed at the center or any position of the display unit of the aiming device. As in step S430, an instruction is received to adjust the position of the reticle until the reticle moves to the landing point displayed in the display unit, thus completing the marking of the reticle for that landing point. Then, as in step S440, it is determined whether the marking of the reticles for all landing points has been completed. If the marking of the reticles for all landing points has not been completed (No in step S440), the process returns to step S430 to perform the marking operation for the reticle of the next landing point. If the marking of the reticles for all landing points has been completed (Yes in step S440), the process ends.

[0035] It must be noted that the purpose of the reticle in the calibration process of this application is different from that of the reticle in a traditional sight. Figure 5 This invention illustrates a calibration method for an aiming device according to another embodiment of the present invention. In this embodiment, the application provides two modes: a standard curve establishment mode and an impact point compensation shooting mode. In other words, in the standard curve establishment mode, the reticle system is used for impact point marking, while in the impact point compensation shooting mode, the reticle system is used for impact point indication during firing.

[0036] First, as in step S510, an instruction is received to determine whether the aiming device should enter the standard curve establishment mode or the impact point compensation firing mode. It is worth noting that the aiming device includes an objective lens unit facing the impact point direction, a display unit for viewing the impact point, and a control unit. The control unit includes the standard curve establishment mode and the impact point compensation firing mode, and, according to the instruction, causes the aiming device to enter either the standard curve establishment mode or the impact point compensation firing mode. It is noteworthy that in some embodiments, the user can input via buttons or voice. It is worth noting that the method of receiving instructions can be designed according to different needs and applications, and the present invention is not limited to this. When entering the standard curve establishment mode, as in step S520, the aiming device calibration method of this application is executed. In other words, the firing trajectory of the corresponding firing device is calculated based on the specific distances from the corresponding plurality of impact points to the firing device and the reticle markings indicating the positions of individual impact points in the display unit of the aiming device. When entering the impact point compensation firing mode, as in step S530, the impact point instruction for the corresponding firing operation is given based on the firing trajectory.

[0037] Figure 6 This illustrates a calibration method for an aiming device according to another embodiment of the present invention. The calibration method for an aiming device according to an embodiment of the present invention is applicable to, for example... Figure 1 The aiming device 100 can be detachably attached to the firing device 200, such as a crossbow. Figure 7 As shown. In this example, the three impact points M1, M2, and M3 can be used to calibrate the corresponding aiming device 100. Impact point M1 is L1 distance from the firing device 200, impact point M2 is L2 distance from the firing device 200, and impact point M3 is L3 distance from the firing device 200. L1, L2, and L3 are 30 yards, 50 yards, and 70 yards, respectively.

[0038] It should be noted that in some embodiments, the crossbow may have a single-shot mode or a multi-shot mode, wherein... Figure 6 , Figure 7 This is equivalent to a single-shot mode. In multi-shot mode, when multiple arrows are arranged side-by-side in a fan shape, with each arrow having a different angle to the horizontal plane (i.e., arranged from top to bottom), it should be noted that in some embodiments, the arrows may be arranged in other ways; this invention is not limited to any particular arrangement. Based on the parabolic shooting principle, arrows with a larger angle to the plane will travel a greater distance than arrows with a smaller angle. In other words, although fired simultaneously, the different launch angles result in different landing points, making it possible to observe multiple landing points at once and mark them.

[0039] First, as in step S610, a zeroing operation is performed on the aiming device at a corresponding zeroing distance, where the zeroing distance is less than a specific distance for each landing point. Similarly, in some embodiments, the zeroing distance may be 20 yards. Next, as in step S620, an instruction is received causing the aiming device to enter a standard curve establishment mode, and the calibration initial interface is displayed through the aiming device's display unit. For example, when entering the standard curve establishment mode, the aiming device's display unit may display a reticle at the center position, such as... Figure 8 As shown. It is worth noting that in some embodiments, a specific button on the aiming device, such as the power button, can be pressed and held for 5 seconds to enter the standard curve establishment mode. Then, as in step S630, a switching command is received to select between specific distances for different landing points. Figure 8 The diagram illustrates a specific distance according to an embodiment of the present invention, such as a 30-yard calibration initial interface 810. It is worth noting that in some embodiments, the firing or aiming device may include a ranging unit, such as a rangefinder. When the firing or aiming device includes a ranging unit, the aforementioned specific distance can also be measured by that ranging unit. In some embodiments, the aiming device includes at least a laser emitting unit, a laser receiving unit, and a unit comprising an objective lens unit, an eyepiece unit, and a relay lens assembly unit, wherein the objective lens unit and the eyepiece unit define a first optical axis, and the relay lens assembly unit is disposed between the objective lens unit and the eyepiece unit. The objective lens unit has a first imaging plane (i.e., the focal length position of the entire objective lens unit), and the relay lens assembly unit has a second optical axis and a second imaging plane (i.e., the focal length position of the entire relay lens assembly unit). It further includes an adjustment unit. The relay lens assembly is positioned perpendicular to the first optical axis and connected to it. When the adjustment unit adjusts the relay lens assembly, the second optical axis can be adjusted to be parallel to or form an angle with the first optical axis. The laser emitting unit and the laser receiving unit are not located on the optical axis, and the display unit may be located on or not on the first optical axis. When the display unit is not located on the first optical axis, it can partially overlap with the optical axis via a prism unit and enter the eyepiece unit. When the display unit is located on the first optical axis (i.e., on the first or second imaging surface), it generates a light beam that travels towards the eyepiece unit along the first optical axis, allowing the user to view the display unit through the eyepiece unit. The relay lens assembly may have optical zoom features.

[0040] In some embodiments, pressing a specific button on the aiming device, such as the power button, once allows switching between calibration initial interfaces at different specific distances. Once a specific distance is determined, the user can press and hold that specific button on the aiming device, such as the power button, for 5 seconds to perform calibration at the corresponding landing point. During calibration, as in step S640, an instruction is received to adjust the position of the reticle until it moves to the landing point displayed on the display unit, thus completing the marking of the reticle at the corresponding landing point. It is worth noting that in some embodiments, during the marking of the landing point, pressing a specific button, such as the power button, can generate a downward movement instruction, illuminating the reticle in a sequence of "single reticle, double reticle, single reticle, double reticle,...". Alternatively, pressing a specific button, such as the mode button, can generate an upward movement instruction, illuminating the reticle in a sequence of "single reticle, double reticle, single reticle, double reticle,...". In this embodiment, when the landing point is located on a reticle line, the single reticle 910 at that location can be illuminated, such as... Figure 9 As shown. When the landing point is between the scribe lines, the double scribe line 920, consisting of two scribe lines, can be illuminated, as shown. Figure 10 As shown. It should be noted that... Figure 9 and Figure 10 The black dot BD in the image represents the position of the actual impact point on the target as displayed on the aiming device's display unit. It's worth noting that in some embodiments, this impact point can be seen by the user through a transmissive display, similar to the viewfinder of a monocular lens. In some embodiments, the impact point can be displayed on the screen via an image sensor, similar to a monocular lens display. In other words, the user can observe the impact point on the screen. Then, as in step S650, it is determined whether the marking of the reticle for all impact points has been completed. If not, the process returns to step S630, selecting another impact point for subsequent reticle marking. If the marking of the reticle for all impact points has been completed (yes, as in step S650), the process ends. For example, when the marking of impact points at different specific distances is completed, the aiming device's display unit can display... Figure 11Image 1010. It is worth noting that the aforementioned specific distances are merely examples from this application. These three distances do not need to be an arithmetic sequence. In some embodiments, these three distances can be non-arithmetic sequences; for example, these three distances can be any three distances, and can be integers or non-integers. Furthermore, it should be noted again that in some embodiments, the shooting device or aiming device may include a ranging unit. In some embodiments, the ranging unit may include a laser emitting unit and a laser receiving unit. The laser emitting unit emits a measurement beam, which passes through the objective lens unit towards the first landing point, is reflected by the first landing point to form a reflected beam, and then passes through the objective lens unit to reach the laser receiving unit, thereby obtaining the distance value of the first landing point. In some embodiments, the ranging unit includes a laser emitting unit, a laser receiving unit, and a ranging objective lens unit. The laser emitting unit emits a measurement beam, which passes through the rangefinding objective lens unit and is directed towards the first impact point. Reflected by the first impact point, it forms a reflected beam, which then passes through the objective lens unit or the rangefinding objective lens unit to reach the laser receiving unit, thereby obtaining the distance value of the first impact point. When the firing or aiming device includes a rangefinding unit, the aforementioned specific distance can also be measured by that rangefinding unit. It is worth noting that in some embodiments, when the reticle lines for all corresponding impact points have been marked, the user can input an instruction, such as pressing and holding a specific button on the aiming device, such as the mode button, for 5 seconds to exit the standard curve establishment mode and enter the impact point compensation firing mode. It is worth noting again that in... Figure 6 The embodiment is an example of a single-shot mode. In some embodiments, multiple impact points can also be generated / viewed simultaneously in a multi-shot mode, and subsequent marking operations can be performed.

[0041] Therefore, the aiming device calibration method and aiming device of this application can mark the actual impact point in the display unit of the aiming device using reticle lines based on the actual impact point of the shooting device at different distances, and simulate the real shooting trajectory using linear fitting, thereby achieving an accurate impact point indication effect. It must be reiterated that the impact point can be seen by the user through a transmissive display, similar to the viewfinder of a monocular lens. In some embodiments, the impact point can be presented on the display via an image sensor, similar to a monocular lens display. In other words, the user can observe the impact point on the display. Furthermore, the appearance of the mark can be automatically recognized, such as through a face autofocus symbol similar to that of a camera, or manually, such as through a face manual focus symbol similar to that of a camera.

The program code may be contained in physical media, such as floppy disks, optical discs, hard disks, or any other machine-readable (e.g., computer-readable) storage media, or may be a computer program product, not limited to an external form, wherein when the program code is loaded and executed by a machine, such as a computer, that machine becomes an apparatus for participating in the present invention. The program code may also be transmitted via some transmission medium, such as wires or cables, optical fibers, or any transmission method, wherein when the program code is received, loaded, and executed by a machine, such as a computer, that machine becomes an apparatus for participating in the present invention. When implemented in a general-purpose processing unit, the program code, in conjunction with the processing unit, provides a unique apparatus that operates similarly to an application-specific logic circuit.
