Description

Aiming system and its reticle adjustment method, equipment and medium Technical Field

[0001] This application relates to the field of aiming technology, and specifically to an aiming system and its reticle adjustment method, apparatus, equipment, and medium. Background Technology

[0002] To improve shooting efficiency and accuracy, people have invented various instruments and devices over the years to help users aim guns or bows and arrows at targets. Aiming devices used in launchers to achieve target aiming can generally be divided into two types: telescopic sights and reflex sights. Of course, there are also aiming devices designed based on other principles. Different aiming devices are suitable for different applications.

[0003] To help users accurately, conveniently, and quickly hit potential targets, existing aiming devices generally use reticles to assist in target location. However, the design of existing reticles has several shortcomings. For example, the display screens used to show the reticles in some aiming devices on the market are basically built-in screens, and the reticle size cannot be adjusted according to the user's needs. Furthermore, although existing holographic aiming devices use external screens to display the reticles, their reticle screens are small, making them difficult to observe in some application scenarios and prone to misreading the mil-dots. Clearly, the current reticle settings in aiming devices are not conducive to improving aiming accuracy. Summary of the Invention

[0004] To at least partially improve the technical problems existing in the prior art, this application provides an aiming system with high aiming accuracy whose reticle can be adjusted according to user needs, as well as a reticle adjustment method, device and computer-readable medium thereof.

[0005] According to a first aspect of the embodiments of this application, a reticle adjustment method for an aiming system is provided. The aiming system includes an aiming body, an image acquisition device disposed on the aiming body, and a display device. The display interface of the display device is used to overlay and display a reticle image and a field-of-view image acquired by the image acquisition device. The reticle adjustment method includes:

[0006] User adjustment commands are obtained based on the control area of ​​the display interface;

[0007] The user adjustment command is identified to determine its category;

[0008] According to the type of user adjustment command, the reticle image in the display interface is adjusted accordingly until the reticle image is observed by the human eye observation position of the aiming system and meets the preset conditions.

[0009] According to a second aspect of the embodiments of this application, a display device is provided, including a memory and a processor, wherein the memory stores a computer program that can be executed by the processor, and the computer program, when executed by the processor, implements the aforementioned division adjustment method.

[0010] According to a third aspect of the embodiments of this application, an aiming system is provided, including an aiming body, an image acquisition device and a display device disposed on the aiming body, wherein the aiming body is provided with a human eye observation position corresponding to the display device;

[0011] The display device includes a processor and a display screen. When the processor executes a computer program, it implements the reticle adjustment method. The display screen is used to display the display interface containing the reticle image.

[0012] The image acquisition device is used to acquire a field image containing the target object and send the field image to the processor. The processor is also used to overlay the field image and the reticle image on the display interface so that when the human eye observes from the observation position, aiming adjustment of the target object can be realized based on the relative position of the target object in the reticle image and the field image.

[0013] According to a fourth aspect of the embodiments of this application, a computer-readable storage medium is provided, on which a computer program is stored, and when the computer program is executed by a processor, it implements the division adjustment method described above.

[0014] As can be seen from the above, the aiming system provided in this application includes an aiming body and an image acquisition device and a display device respectively disposed on the aiming body. In the reticle adjustment method applied to the aiming system provided in this application, user adjustment commands representing the user's adjustment needs for the reticle image on the display interface are acquired through user touch based on the display interface of the display device. Then, the user adjustment commands are identified, and the reticle image on the display interface is adjusted accordingly based on the type of user adjustment command, until the reticle image is observed to meet preset conditions at the human eye observation position of the aiming system. Therefore, the reticle adjustment method provided in this application embodiment can directly adjust the reticle according to the user's needs based on the user's touch operation on the display interface to obtain a reticle suitable for the current aiming scenario, so as to facilitate user operation and observation and achieve high aiming accuracy.

Detailed Implementation

[0031] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the ways in which this application may be implemented. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] In the following description, the expression “some embodiments” is used, which describes a subset of possible embodiments. However, it should be understood that “some embodiments” can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0034] Please refer to Figures 1 and 2 respectively. Figure 1 is a schematic flowchart of the reticle adjustment method for an aiming system provided according to some embodiments of this application. Figure 2 is a schematic structural diagram of the aiming system used in the reticle adjustment method provided in some embodiments of this application. In this embodiment, the aiming system used in the reticle adjustment method includes an aiming body 1, an image acquisition device 2 disposed on the aiming body 1, and a display device 3. Further, the aiming body 1 is provided with a human eye observation position corresponding to the display device 3 (not shown in Figure 1). The display interface of the display device 3 is used to overlay and display the reticle image and the field of view image acquired by the image acquisition device. The reticle adjustment method in this embodiment includes S02 and S04, which are described below.

[0035] S02: Obtain user adjustment commands based on the control area of ​​the display interface.

[0036] Please refer to Figure 3, which is a schematic diagram of the display interface of the aiming system provided according to some embodiments of this application during aiming. When a user aims at a target using the aiming system of Figure 2, the display interface of the display device 3 will overlay a reticle image 32 and a field of view image 33. The user can observe the relative position of the target object in the field of view image and the reticle image from the human eye's observation position, and adjust the aiming of the target object based on this relative position. To facilitate user observation, before adjusting the aiming based on the relative position of the target object and the reticle image 32 in the display interface, the user can also input corresponding user adjustment commands based on the display interface of the display device 3 according to their own adjustment needs for the reticle image 32, so that the display device 3 can adjust the reticle image 32 accordingly based on the corresponding user adjustment commands, thereby ensuring that the reticle image 32 meets preset conditions, that is, meets the user's current needs, during the aiming adjustment of the target object.

[0037] The control area of ​​the display interface can receive corresponding user adjustment commands. Users can directly input these commands by touching the control area of ​​the display interface. This eliminates the need for hardware structures such as buttons when adjusting the reticle; instead, users can operate directly on the display interface via touch, making it more intuitive, faster, and greatly facilitating user operation. User adjustment commands represent the user's current adjustment needs for the reticle image. Adjusting the reticle image includes making corresponding adjustments to its size, position, and style.

[0038] S04: Identify user adjustment commands and obtain the category of the user adjustment commands.

[0039] In some embodiments, a specific implementation for identifying user adjustment commands can be: identifying the current touch operation category of the control area, and determining the category of the currently acquired user adjustment command based on the touch operation category. In some embodiments, different touch operation categories correspond to different touch positions of the control area, and / or, different touch operation categories correspond to different touch methods (e.g., touch or swipe) of the control area.

[0040] S06: Adjust the reticle image on the display interface according to the type of user adjustment command until the reticle image meets the preset conditions when observed by the human eye at the aiming system.

[0041] The preset conditions can be determined based on the user's current adjustment needs. The reticle image meeting the preset conditions satisfies the user's current needs. Referring to Figure 3, in some embodiments, the user observes the display interface of the display device 3 through the peephole 113. The user's current adjustment need is that the reticle image 32 observed through the peephole 113 coincides with the peephole 113. That is, in this embodiment, the preset condition in S06 is that when the display interface is observed through the peephole, the reticle image 32 coincides with the peephole 113. It should be noted that the peephole 113 in Figure 3 is not actually displayed on the display interface, but is drawn in the schematic diagram of the display interface structure to illustrate the preset conditions met by the reticle image. In this embodiment, the position corresponding to the peephole 113 is the human eye observation position, and the peephole 113 is set on the aiming body.

[0042] In this embodiment, the display interface refers to an interface that can display images such as reticle images and field images. Before adjusting the reticle image 32 in the display interface based on the user's adjustment command, the reticle image 32 can also be displayed in the display interface based on the reticle display command input by the user to the display device 3, such as the user's corresponding touch operation on the display interface.

[0043] As can be seen from the above, in the reticle adjustment method provided according to some embodiments of this application, user adjustment commands representing the user's adjustment needs for the reticle image on the display interface are obtained through user touch on the display interface of the display device. Then, the user adjustment commands are identified, and the reticle image on the display interface is adjusted accordingly based on the category of the user adjustment command, until the reticle image meets preset conditions as observed by the human eye at the aiming system. Therefore, the reticle adjustment method provided in some embodiments of this application can adjust the reticle to obtain a suitable reticle for the current aiming scenario according to user needs, facilitating user observation and achieving high aiming accuracy.

[0044] In some embodiments, the user adjustment command includes a position movement command, a zoom-out command, and a zoom-in command. When the user adjustment command is a position movement command, S06 above includes: adjusting the position of the reticle image on the display interface according to the position movement command until the position of the reticle image on the display interface meets a preset position condition when observed by the human eye. When the user adjustment command is a zoom-out command or a zoom-in command, S06 above specifically includes: adjusting the size of the reticle image on the display interface according to the zoom-out command or the zoom-in command until the size of the reticle image on the display interface meets a preset size condition when observed by the human eye. In the reticle adjustment method provided in this application embodiment, the size and position of the reticle image can be adjusted accordingly based on the user adjustment command to facilitate the user's observation of the reticle image, thereby improving the aiming accuracy of the aiming system.

[0045] In some embodiments, the preset conditions include the preset position condition and the preset size condition. The preset position condition refers to the position of the reticle image in the display interface that meets the user's current needs. For example, in Figure 3, the preset position condition for the reticle image 32 is that, as observed from the peephole 113, the reticle image 3 is located at the projection area of ​​the peephole 113 in the display interface; specifically, the center position of the reticle image 3 coincides with the center position of the projection area of ​​the peephole 113 in the display interface. Similarly, in Figure 3, the preset size condition for the reticle image 32 is that, as observed from the peephole 113, the size of the reticle image 3 that meets the preset position condition is the same as the size of the projection area of ​​the peephole 113 in the display interface. Therefore, in this embodiment, after adjusting the position and / or size of the reticle image 32 according to the user's adjustment command, the center position of the reticle image 32 can be observed from the peephole 113 to coincide with the center position of the projection area of ​​the peephole 113 in the display interface, and the size of the reticle image 32 is the same as the size of the projection area of ​​the peephole 113 in the display interface. In some embodiments, prior to adjusting the position and / or size of the reticle image 32, the shape of the reticle image 32 is also adjusted so that the reticle image 32 has the same shape as the peephole 113 for easy observation by the user.

[0046] In some embodiments, the user adjustment command further includes a color selection command and a pattern style selection command. When the user adjustment command is a color selection command, S06 further includes: adjusting the display color of the reticle image on the display interface according to the color selection command until the display color of the reticle image on the display interface, as observed by the human eye, meets a preset display color condition. When the user adjustment command is a pattern style selection command, S06 further includes: adjusting the pattern style of the reticle image on the display interface according to the pattern style selection command until the pattern style of the reticle image on the display interface, as observed by the human eye, meets a preset pattern style condition. In this embodiment, by adjusting the color and / or pattern style of the reticle image according to the user adjustment command, it is easier for the user to observe and helps to improve aiming accuracy.

[0047] In the reticle adjustment method provided according to some embodiments of this application, the color of the reticle image is adjusted according to user needs to maximize the distinction between the color of the reticle image and the color of the target object in the field of view, facilitating the user's observation of the relative positional changes of the target object and the reticle image, thereby improving aiming accuracy. Furthermore, different aiming scenarios require different reticle pattern styles. Adjusting the pattern style of the reticle image ensures that the pattern style is best suited to the current aiming scenario, further improving aiming accuracy. The aforementioned preset conditions also include preset color conditions and preset pattern style conditions, wherein the preset color condition is a color of the reticle image that meets the user's current needs, and the preset pattern style condition is a pattern style of the reticle image that meets the user's current needs.

[0048] In some embodiments of the reticle adjustment method, the display state of the reticle image is adjusted based on user adjustment commands so that the display state of the reticle image observed from the human eye's viewing position meets a preset display state. The adjustment of the display state of the reticle image includes the aforementioned adjustment of the reticle image's color and pattern style. In other embodiments, the adjustment of the reticle image's display state also includes adjusting the reticle image's brightness based on user adjustment commands to facilitate user observation.

[0049] Please refer to Figure 4, which is a schematic diagram of the display interface operation in the reticle adjustment method provided according to some embodiments of this application. In the reticle adjustment method provided according to some embodiments of this application, the control area of ​​the display interface includes the location area of ​​the unlock touch key 34, the zoom-out touch key 35, the zoom-in touch key 36, and the reticle image 32 located on the display interface. The above-mentioned S02, which obtains the user adjustment command based on the control area in the display interface, may specifically include receiving a zoom-out command based on the zoom-out touch key, receiving a zoom-in command based on the zoom-in touch key, receiving a position movement command based on the user operation of touching and dragging the reticle image, receiving a color selection command based on the user operation of sliding the reticle image along a first direction, and receiving a pattern selection command based on the user operation of sliding the reticle image along a second direction.

[0050] The following is a detailed description of the scheme for obtaining user adjustment commands based on the control area of ​​the display interface according to the embodiments of this application, based on Figure 4 and in conjunction with Figures 5 to 7. Figure 5 is a schematic diagram of the display interface operation in the reticle adjustment method provided according to some embodiments of this application; Figure 6 is a schematic diagram of the display interface operation in the reticle adjustment method provided according to some embodiments of this application; and Figure 7 is a schematic diagram of the display interface operation in the reticle adjustment method provided according to some embodiments of this application. In this embodiment, a viewing hole 113 is still provided on the aiming body 1, and the position corresponding to the viewing hole 113 is described as the human eye observation position. It should be noted that the viewing hole 113 is not actually displayed in the display interface of Figures 4 to 7; it is deliberately added to the display interface operation schematic diagram for the purpose of illustrating the adjustment process.

[0051] Referring to Figure 4, the user can input an unlock command to the display device 3 by touching the unlock touch key 34 displayed on the touch display interface. After receiving the unlock command, the processor in the display device 3 will switch the display interface from a locked state to an unlocked state (unlocked state). In the unlocked state of the display interface, the user can touch the position of the crosshair in the reticle image 32 with their finger and drag it to the target position. During the process of the user dragging the reticle image 32 to the target position, the processor in the display device 3 obtains the current position movement command based on the user's current dragging operation and moves the reticle image 32 to the target position according to the position movement command. In some embodiments, the position of the position movement command in the control area is the area where the reticle image 32 is located. In other embodiments, the position movement command further includes a position fine-tuning command, which the user can input through the fine-tuning direction touch keys displayed on the display interface (such as the arrow direction touch keys around the unlock touch key 34). The processor in display device 3 fine-tunes the position of the reticle image 32 according to the acquired fine-tuning instructions, ultimately ensuring that the position of the reticle image 32 meets preset position conditions, such as positioning the crosshair at the center of the reticle image 32 at the center of the projection area of ​​the peephole 113 on the display interface. The adjustment range of the reticle image 32 based on the position movement instructions is greater than the adjustment range based on the fine-tuning instructions. In this embodiment, the user transmits corresponding position movement instructions to display device 3 by touching and dragging the reticle image 32 on the display interface or by touching the fine-tuning direction touch keys. That is, the processor in display device 3 acquires the corresponding position movement instructions based on the dragging operation of the reticle image on the display interface and the button operation of the fine-tuning direction touch keys, so as to move the reticle image 32 to the target position for user observation.

[0052] Referring to Figure 4, after adjusting the position of the reticle image 32 to meet the preset position conditions, the user can further input a user adjustment command to the display device to adjust the size of the reticle image based on the size of the reticle image 32 seen through the peephole 113. In this embodiment, the user adjustment command also includes a zoom-out command and a zoom-in command. If the user observes that the reticle image 32 is too small, it needs to be zoomed in. The user can tap the zoom-in touch key 36 on the display interface shown in Figure 4. The processor in the display device 3 determines whether it has received a zoom-in command from the user by recognizing whether the zoom-in touch key 36 has been touched. If it has, the processor zooms in on the size of the reticle image 32 according to the zoom-in command. Conversely, if the user observes that the reticle image is too small, it needs to be scaled down. The user can tap the zoom-out touch key 35 on the display interface shown in Figure 4. The processor of the display device 3 determines whether it has received a zoom-out command from the user by recognizing whether the zoom-out touch key 35 has been touched. If so, it scales down the size of the reticle image 32 according to the zoom-in and / or zoom-out commands input by the user. In this embodiment, the processor of the display device 3 adjusts the size of the reticle image 32 according to the user's zoom-in and / or zoom-out commands until the size of the reticle image 32 meets the preset size conditions, at which point the adjustment stops and the current position, size, and display state of the reticle image 32 are saved. Optionally, in this embodiment, the icon for the zoom-out touch key 35 can be represented by "-", and the icon for the zoom-in touch key 36 can be represented by "+". The processor in the display device 3 obtains the user's zoom-out command based on the zoom-out touch key 35 and the user's zoom-in command based on the zoom-in touch key 36.

[0053] Furthermore, referring to Figure 4, in this embodiment, based on the user's current needs for the color of the segmented image, the user can also input a color selection command through the display interface of the display device 3. After receiving the color selection command, the processor of the display device 3 adjusts the segmented image 32 to the color corresponding to the color selection command for easy observation by the user. Specifically, in this embodiment, the user can slide the segmented image 32 up and down in a first direction with their finger to input the corresponding color selection command to the processor of the display device 3. That is, the processor of the display device 3 receives the color selection command based on the user's operation of sliding the segmented image along the first direction. Specifically, in this embodiment, the first direction is the up and down direction indicated by the arrow in Figure 4.

[0054] Furthermore, referring to Figure 5, in this embodiment, based on the user's needs for the pattern style of the reticle image, the user can also input a pattern style selection command through the display interface of the display device 3. After the processor in the display device 3 receives the pattern style selection command, it adjusts the reticle image 32 to a pattern style corresponding to the pattern style selection command, so as to facilitate user observation. Specifically, in this embodiment, the user can slide the reticle image 32 left or right in the second direction with their finger to input the corresponding pattern style selection command to the processor of the display device 3. That is, the processor of the display device 3 receives the pattern style selection command based on the user's operation of sliding the reticle image along the second direction. Specifically, in this embodiment, the second direction is the left and right direction indicated by the arrow in Figure 5.

[0055] Furthermore, referring to Figure 6, in this embodiment, after the user has adjusted the segmented image 32 to meet the preset conditions, they can further click the lock / unlock touch key 34 to input a lock command to the processor of the display device 3. Based on the acquired lock command, the processor in the display device 3 will switch the state of the display interface from unlocked to locked. After the display interface is locked, the display device 3 saves information such as the position, size, pattern style, and color of the current segmented image 32. The user cannot adjust the segmented image 32 while the display interface is locked. If further adjustment of the segmented image 32 is required, the user needs to input the unlock command again using the unlock touch key 34 so that the processor in the display device 3 can switch the state of the display interface back to unlock before adjustment can be performed.

[0056] Please refer to Figure 7. In this embodiment, after the display interface is locked, the user can click any location in the non-control area of ​​the display interface to hide the icons of each touch key in the display interface, so as to avoid interference with the user's observation during the aiming adjustment process. The non-control area in the display interface is the area outside the control area of ​​the display interface. The control area of ​​the display interface refers to the user's control area when adjusting the reticle image, which includes the area where each touch key is located and the area where the reticle image is located.

[0057] Please refer to Figure 8, which is a schematic flowchart of the reticle adjustment method for an aiming system provided according to any embodiment of this application. In this embodiment, before S02, S012 and S014 are further included, as described in detail below.

[0058] S012: Based on the touch display command received from the display interface, display the unlock touch key, shrink touch key, and zoom touch key on the display interface.

[0059] S014: Based on the unlock command received from the unlock touch key, the control area of ​​the control display interface is in an unlocked state.

[0060] Specifically, when using the aiming system employing the reticle adjustment method provided in this application embodiment, the user can click any or a specified location on the display interface to transmit a touch display command to the display device 3 when adjustments to the reticle image are needed. After each touch key is displayed on the display interface, the user can transmit an unlock command to the display device 3 based on the unlock touch key. That is, the display device 3 receives the unlock command based on the unlock touch key and switches the display interface from a locked state to an unlocked state according to the command. When the display interface is in the unlocked state, the control area of ​​the display interface can be operated by the user. That is, the user can transmit corresponding user adjustment commands to the display device 3 based on the control area to perform corresponding adjustments to the reticle image according to the type of user adjustment command, until the adjustment stops when the reticle image meets the preset conditions observed by the human eye.

[0061] Please refer to Figure 8. After the display device 3 has completed the adjustment of the segmented image, it further includes S072 and S074, which are described in detail below.

[0062] S072: Based on the lock command received from the unlock touch key, the control area of ​​the control display interface is locked.

[0063] S074: Receive touch hide command based on areas other than the control area in the display interface, and hide, shrink, and enlarge touch keys in the display interface according to the touch hide command.

[0064] After the display device 3 adjusts the reticle image according to the user's needs, it maintains the adjusted reticle image. The user touches the unlock key to transmit a lock command to the display device 3. Based on the lock command, the display device 3 switches the display interface to a locked state, meaning the control area of ​​the display interface is in a locked state that cannot be controlled by the user. To facilitate the user's observation of the relative position of the reticle image and the target object, after locking the display interface, the display device 3 can also obtain the touch hide command transmitted by the user based on the non-control area of ​​the display interface, and hide each touch key in the display interface according to the command.

[0065] Please refer to Figure 9, which is a schematic diagram of the reticle display device of an aiming system provided according to any embodiment of this application. In this embodiment, the reticle display device includes an acquisition module 101, an identification module 102, and a reticle adjustment module 103. The acquisition module 101 is used to acquire user adjustment commands based on the control area of ​​the display interface. The identification module 102 is used to identify the user adjustment commands and obtain the category of the user adjustment commands. The reticle adjustment module 103 is used to adjust the reticle image in the display interface according to the category of the user adjustment commands until the reticle image meets preset conditions when observed by the human eye at the aiming system's observation position. The reticle display device provided in this application embodiment and the reticle adjustment method provided in this application embodiment achieve the same technical effect, and will not be described further here.

[0066] Optionally, the user adjustment commands include position movement commands, zoom-out commands, and zoom-in commands. When the user adjustment command is a position movement command, the reticle adjustment module 103 is specifically used to adjust the position of the reticle image on the display interface according to the position movement command until the position of the reticle image on the display interface meets the preset position conditions observed by the human eye. When the user adjustment command is a zoom-out command or a zoom-in command, the reticle adjustment module 103 is specifically used to adjust the size of the reticle image on the display interface according to the zoom-out command or the zoom-in command until the size of the reticle image on the display interface meets the preset size conditions observed by the human eye.

[0067] Optionally, the user adjustment commands also include color selection commands and pattern style selection commands. When the user adjustment command is a color selection command, the reticle adjustment module 103 is specifically used to adjust the display color of the reticle image on the display interface according to the color selection command until the display color of the reticle image on the display interface, as observed by the human eye, meets the preset display color conditions. When the user adjustment command is a pattern style selection command, the reticle adjustment module 103 is specifically used to adjust the pattern style of the reticle image on the display interface according to the pattern style selection command until the pattern style of the reticle image on the display interface, as observed by the human eye, meets the preset pattern style conditions.

[0068] Optionally, the control area includes an unlock touch key, a zoom-out touch key, a zoom-in touch key, and the location area of ​​the reticle image located on the display interface.

[0070] Optionally, the unlock control module is also specifically used to adjust the reticle image on the display interface according to the type of user adjustment command, until the reticle image is observed by the human eye observation position of the aiming system to meet the preset conditions, and then control the control area of ​​the display interface to be locked based on the lock command obtained from the unlock touch key, and obtain touch hiding commands based on other areas of the display interface other than the control area, and hide the unlock touch key, shrink the touch key and enlarge the touch key on the display interface according to the touch hiding commands.

[0071] Please refer to Figure 10, which is a schematic diagram of the structure of a reticle adjustment device according to any embodiment of this application. In this embodiment, the reticle adjustment device includes a memory 201 and a processor 202. The memory 201 stores a computer program executable by the processor 202. When the computer program is executed by the processor 202, it implements the reticle adjustment method according to any embodiment of this application. The reticle adjustment device and the reticle adjustment method provided in this application achieve the same technical effects, and will not be described further here.

[0072] In some embodiments, this application also provides an aiming system as shown in FIG1, which includes an aiming body 1, an image acquisition device 2 disposed on the aiming body 1, and a display device 3. The aiming body 1 is provided with a human eye observation position corresponding to the display device 3. The display device 3 includes a processor and a display screen. When the processor of the display device 3 executes a computer program, it implements the reticle adjustment method provided in any embodiment of this application. The display screen of the display device 3 is used to display a display interface containing a reticle image. The image acquisition device 2 is used to acquire a field image containing a target object and send the field image to the processor of the display device 3. The processor of the display device 3 is also used to superimpose the field image and the reticle image on the display interface so that aiming adjustment of the target object can be achieved based on the relative position of the target object in the reticle image and the field image when observed from the human eye observation position.

[0073] The aiming body 1 can be a shooting device such as a gun or bow and arrow used for aiming and shooting at a target, or it can simply be a support frame for the image acquisition device 2 and the display device 3. The human eye observation position on the aiming body 1 corresponding to the display device 3 means that during the aiming process, the user's eye observes the display screen of the display device 3 from this human eye observation position. In other words, the display screen of the display device 3 is located within the field of view corresponding to the human eye observation position.

[0074] In some embodiments, the aiming body 1 is provided with a peephole, the position corresponding to the human eye's observation position. The peephole, display device 3, and image acquisition device 2 are arranged sequentially in the direction of human eye observation. The display device 3 and image acquisition device 2 can be an integrated device, with a camera on one side for image acquisition and a display screen on the other side. Alternatively, the display device 3 and image acquisition device 2 can be separate devices, signal-connected and detachably mounted on the aiming body 1. The preset condition is that the reticle image within the human eye's field of view coincides with the peephole. In this embodiment, when the user uses the aiming system, the user's eye observes the display screen of the display device 3 through the peephole on the aiming body 1.

[0075] Display device 3 may be equipped with an aiming app. When a user aims at a target object using the aiming system, the user can open the aiming app based on operations on display device 3. This app displays a screen with a reticle image on the display screen of display device 3. Before adjusting the aim at the target object, the user can adjust the position, size, and / or display status of the reticle image on the display screen until the reticle image on the display screen meets preset conditions when observed by the user from the human eye's observation position. At this point, the adjustment of the reticle image stops, and the adjusted reticle image is maintained on the display screen, i.e., the reticle image that meets the preset conditions is maintained. Here, "the reticle image meets the preset conditions" means that the reticle image meets the reticle image expected by the user when observed from the human eye's observation position. For example, in some embodiments, when the human eye is aiming at the position corresponding to the peephole or observation window on the main body 1, the human eye observes the display screen of the display device 3 through the peephole. During the adjustment of the reticle image, if the reticle image coincides with the peephole, it indicates that the reticle image has been adjusted to meet the preset conditions. Therefore, the adjustment of the reticle image is stopped, and the reticle image within the observation field of view is kept in a state of coincidence with the peephole before proceeding to subsequent aiming adjustments. It should be noted that this coincidence is not absolute, but rather coincidence within the error tolerance range. That is, while it is permissible for the reticle image and the peephole to coincide within the observation field of view, a certain deviation is allowed within the error tolerance range. In this embodiment, the reticle image coinciding with the peephole means that within the observation field of view, the reticle image is located within the outline of the peephole and its size is consistent with the size of the peephole.

[0076] The processor in display device 3 obtains user adjustment commands based on the display interface of display device 3 to adjust the reticle image accordingly. When observing from the human eye's position, the relative position of the target object in the field of view image to the reticle image refers to the position of the target object relative to the center of the reticle image (i.e., the origin of the reticle coordinates).

[0077] Image acquisition device 2 is positioned downstream of display device 3 in the observation direction corresponding to the human eye observation position, meaning image acquisition device 2 is farther away from the human eye observation position relative to display device 3. Furthermore, in the aiming system, the human eye observation position, display device 3, and image acquisition device 2 are coaxially arranged in the human eye observation direction. The field of view of image acquisition device 3 changes accordingly with the movement of aiming body 1; that is, the field of view of image acquisition device 3 is adjusted by the movement of aiming body 1, so that during aiming, the field of view of image acquisition device 3 can acquire a real-time image of the field of view containing the target object and send it to display device 3. Image acquisition device 3 can be a thermal imager or a night vision device.

[0078] In the aiming system provided in this application embodiment, as the aiming body 1 moves, the field of view of the image acquisition device 1 also changes accordingly, causing the position of the target object in the field of view image to change accordingly. Consequently, the relative position of the target object displayed on the display device 3 at the user's eye observation position and the reticle image also changes accordingly. When the observed relative position meets the aiming conditions, it indicates that the aiming system has now aimed at the target object. Therefore, when using the aiming system provided in some embodiments of this application, the user first displays the reticle image on the display device 3 and adjusts the reticle image to meet preset conditions within the observation field of view corresponding to the user's eye observation position. After the reticle image is adjusted, its position, size, and display status on display device 3 remain unchanged. Then, the aiming system begins aiming adjustment of the target object. This aiming adjustment process includes: image acquisition device 2 following the movement of aiming body 1 to acquire a field-of-view image containing the target object and sending it to display device 3. Display device 3 displays the superimposed field-of-view image and the adjusted reticle image on the display interface. As aiming body 1 moves, the relative positions of the observed reticle image and the target object change relative to each other when the user observes the display interface of display device 3 from the user's eye position. Thus, aiming adjustment of the target object is achieved based on the relative position of the target object in the reticle image and the field-of-view image on the display interface. Specifically, during this aiming adjustment process, aiming body 1 is moved based on the relative position of the target object in the reticle image and the field-of-view image on the display interface until the relative position meets the aiming conditions. In some embodiments, when the reticle image and the field of view image are superimposed on the display interface of the display device 3, the reticle image is located at the center of the field of view image. When the target object is also located at the center of the field of view image acquired by the image acquisition device 2, the center of the target object overlaps with the center of the reticle image, and at this time, it is considered that the aiming system is aiming at the target object. Therefore, in some embodiments, when the relative position between the target object and the reticle image displayed on the display interface of the display device 3 is zero, it indicates that the aiming system is aiming at the target object.

[0079] Optionally, in the aiming system provided according to some embodiments of this application, the display device 3 is detachably mounted in the aiming system, facilitating user replacement. Furthermore, when the aiming system performs aiming adjustments, the user can adjust the reticle image displayed on the display device 3 according to their needs, ensuring that the reticle image observed by the user during aiming adjustments meets their requirements. This allows the user to adjust the aiming of the target object based on the relative position of the target object in the reticle image and the field of view image, improving aiming accuracy. Clearly, the aiming system provided in the embodiments of this application is user-friendly and can be adjusted according to user needs to obtain a reticle suitable for the current aiming scene, facilitating user observation and improving aiming accuracy.

[0080] Please refer to Figure 11, which is a schematic diagram of an aiming system structure provided according to some embodiments of this application. In this embodiment, the aiming body 1 in the aiming system is a compound bow 11. The compound bow includes a bow frame 111 and a bowstring 112, and a viewing hole 113 is provided on the bowstring 112. Optionally, in this embodiment, the image acquisition device 2 is a thermal imager 21, and the display device 3 is a smart terminal 31 with a display screen, which can be a smartphone. The thermal imager 21 is mounted on the first side of the bow frame 111, and the second side of the bow frame 111 has a mounting position (not shown in Figure 11). The smart terminal 31 with a display screen is detachably mounted on the mounting position on the bow frame 111. The second side and the first side are opposite sides, and the second side is closer to the bowstring 112 than the first side. Specifically, the first side and the second side are opposite sides in the direction of human eye observation corresponding to the human eye observation position, that is, the second side and the first side are arranged sequentially along the direction of human eye observation.

[0081] The specific composite bow 11's bow frame 111 comprises two adjacent upper and lower halves. The first and second sides mentioned above are the two sides of the upper half of the bow frame 111. The second side of the lower half of the bow frame 111 is provided with a handle for the composite bow 11, which is the handheld part when the user uses the composite bow 11. Partial enlarged schematic diagrams of the thermal imager 21 and the smart terminal 31 with a display screen mounted on the bow frame 111 are shown in Figures A and B of Figure 11, respectively. The lens axis of the thermal imager 21 and the display screen axis of the smart terminal 31 are parallel or the same. The lens axis can be an axis passing through the center of the lens of the thermal imager 21, and the display screen axis can be an axis passing through the center of the display screen of the smart terminal 31. Optionally, the lens axis and the display screen axis are parallel or the same as the line of sight corresponding to the user's observation position in the aiming system.

[0082] Furthermore, referring to Figure 11, in some embodiments, the position corresponding to the peephole 113 is the human eye observation position. When the user uses the aiming system, their human eye observation position is the position defined by the peephole 113, through which the user observes the display screen of the smart terminal device 31. During the process of the user using the aiming system to aim and adjust the target object, the peephole 113, the smart terminal device 31, and the thermal imager 21 are arranged sequentially in the human eye observation direction.

[0083] In this embodiment, the display device 31 adjusts the reticle image observed by the user through the peephole 113 to meet preset conditions by: adjusting the reticle image into the peephole 113 and aligning it with the peephole 113. The definition of alignment in this application has been explained above and will not be discussed further here.

[0084] Specifically, please refer to Figure 12, which is a structural schematic diagram of the aiming system provided according to some embodiments of this application when aiming at a target object. In this embodiment, with the bowstring 112 of the compound bow 11 in the drawn state, the intelligent terminal device 31 located on the second side of the bow frame 111 adjusts the displayed reticle image according to the user's adjustment command. After the adjustment of the reticle image is completed, with the bowstring 112 in the drawn state, the peephole 113, the reticle image displayed by the intelligent terminal 31, and the thermal imager 21 are all on the line of sight (dashed line in Figure 12) corresponding to the human eye observation position 4.

[0085] Furthermore, please refer to Figure 13, which is a schematic diagram of the aiming system provided according to other embodiments of this application as observed from the human eye's viewing position. After the smart terminal 31 adjusts the size and / or position of the reticle image 32 according to the user's adjustment command, when observed through the peephole 113, the reticle image 32 and the peephole 113 can be observed to overlap, which facilitates the user's observation of the mils in the reticle image, thereby making accurate judgments and improving aiming accuracy.

[0086] To further illustrate the technical effect of the aiming system provided in this application, which can adjust the reticle image based on user adjustment commands, please refer to Figure 14, which is a schematic diagram of the structure corresponding to reticle images of different sizes observed from the human eye observation position in some other embodiments of this application. As can be seen from Figure 14, when the reticle (represented by the reticle image) of the aiming system is too small or too large, it is inconvenient for the user to observe. If it is too small, the mils are not clearly visible; if it is too large, all mils are not visible. Both situations will prevent the user from making accurate judgments based on observation, thus affecting the aiming accuracy. However, when the reticle size meets the preset conditions, that is, when the observed reticle coincides with the peephole, all mils in the reticle can be clearly observed. This allows the user to quickly make accurate judgments based on the relative position of the target object and the reticle image during the aiming adjustment process, thereby effectively improving the accuracy of aiming at the target object.

[0087] Please refer again to Figure 3. The adjusted reticle image 32 is displayed on the display interface of the smart terminal device 31. After acquiring the field of view image 33 sent by the thermal imager 21, the reticle image 32 and the field of view image 33 are superimposed and displayed. As can be clearly seen from Figure 3, after the smart terminal device 31 adjusts the reticle image 32 according to the user's adjustment command, the reticle image 32 observed by the human eye is exactly located within the peephole 113, and its size is consistent with the size of the peephole 113. That is, the reticle image 32 coincides with the peephole 113. In this case, during the aiming adjustment process, the user can clearly observe the mil in the reticle image and can quickly and accurately obtain the relative position between the target object (the cup in Figure 3) and the reticle image 32. When the crosshair (one of the reticle patterns) in the reticle image 32 is aligned with the target object, it indicates that the aiming system is currently aiming at the target object.

[0088] In the aiming system provided according to some embodiments of this application, the reticle is displayed on the display device 3, and the display device 3 can adjust the reticle image according to user needs based on user adjustment commands, making the reticle image easy for the user to observe during aiming adjustment. Specifically, the reticle in the reticle image displayed on the display device 3 can be a crosshair, and the display device 3 can scale the reticle based on user adjustment commands, making it easier for ordinary people to observe. Taking the aiming body 1 as a compound bow 11, the image acquisition device 2 as a thermal imager 21, and the display device 3 as a smart terminal device 31 with a display screen as an example, when the smart terminal device 31 and the thermal imager 21 are assembled on the bow frame 111 of the compound bow 11 at the corresponding positions, the positions of the smart terminal device 31 and the thermal imager 21 are first adjusted, and after they are basically coaxial, their positions on the bow frame 111 are maintained. The position and size of the viewing hole 113 on the bowstring 112 may differ in different aiming systems. Therefore, before aiming at a target object using an aiming system including the compound bow 11, the reticle image displayed on the smart terminal device 31 needs to be adjusted accordingly while the smart terminal device 31 and the thermal imager 21 are powered on. When calibrating and adjusting the compound bow 11, the reticle image 32 displayed on the display device 3 is first adjusted based on the reticle adjustment method provided in any embodiment of this application.

[0089] This application also provides a computer-readable storage medium storing a computer program. When executed by a processor, the computer program implements the various processes in the partitioning adjustment method provided in any embodiment of this application, and achieves the same technical effect. To avoid repetition, further details are omitted here. The computer-readable storage medium includes, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

[0090] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
