Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0034] The invention is further described below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 6 A direct-aiming weapon zero-bullet calibration system shown in the figure comprises a lens barrel 1, a shaft seat 2 is connected to the rear end of the lens barrel 1, an insert shaft 3 is connected to one end of the shaft seat 2, and the insert shaft 3 can be connected to a connecting piece on the outer wall of the gun barrel:

[0035] The lens group 10 is composed of an objective lens module 20 and a prism module 30. The objective lens module 20 is arranged at the front end of the inner wall of the lens barrel 1, and the prism module 30 is arranged at the end of the inner wall of the lens barrel 1;

[0036] A video acquisition module 40 is provided on the shaft seat 2 and can acquire the images captured by the lens group 10;

[0037] A video transmitting module 50 is provided on the shaft seat 2 and can send the images captured by the video capturing module 40 to the operating device;

[0038] A battery pack 60 is provided on the shaft seat 2 and can provide power to the video acquisition module 40 and the video transmission module 50 . A start switch 5 is provided on the shaft seat 2 .

[0039] A further embodiment of the objective lens module 20 of the present invention: the objective lens module 20 includes an objective lens 21 arranged at the front end of the inner wall of the lens barrel 1, a first external thread 22 is provided on the outer wall of the objective lens 21, and a first internal thread 23 that can be connected to the first external thread 22 is provided on the inner wall of the lens barrel 1. The objective lens has high resolution and can identify tiny details in the sample. High resolution means that the image is clearer and can provide more sample information. The numerical aperture of the objective lens is larger and can receive more light, thereby improving resolution and image quality. The larger the numerical aperture, the better the performance of the lens. A high-quality objective lens can well control distortion and ensure that the obtained image is true and accurate. This helps to obtain more reliable observation results.

[0040] A further embodiment of the prism module 30 in the present invention: the prism module 30 includes an annular mounting groove 31 arranged at the end of the inner wall of the lens barrel 1, and a prism lens 32 is embedded in the annular mounting groove 31. The prism lens has the advantages of achieving a longer focal length: the prism lens can increase the focal length by reflecting the path of light, which is suitable for long-distance shooting and can capture details of farther scenery. Since the optical zoom is completed inside the body, the prism lens is easier to install filters, which is very useful for shooting that requires specific filter effects. The prism lens avoids the "bellows" phenomenon that occurs when a traditional lens is zoomed by reflecting light, which helps to maintain the stability of the shooting.

[0041] A further embodiment of the video acquisition module 40 in the present invention: a groove 91 is provided on the planar inner wall of the shaft seat 2, and the video acquisition module 40 is embedded in the groove 91. The video acquisition module 40 is composed of an image sensor, a digital image sensor and a light sensor. The video acquisition device receives analog video signals from external devices through specific interfaces such as S-Video, Composite, HDMI, etc. There is an analog-to-digital converter ADC inside the acquisition device to convert the received analog signal into a digital signal. The converted digital video signal is usually compressed and encoded for storage and transmission. 1. Data transmission: The processed digital video signal is transmitted to the computer's memory through a computer bus such as PCI or PCIe. On the computer, the user can use professional video editing software to further process the acquired video, such as editing, adding special effects, etc.

[0042] A further embodiment of the video transmission module 50 of the present invention: the video transmission module 50 is composed of a wireless transmitter 51 and an antenna 52. The wireless transmitter 51 is fixed on the inner wall of the shaft seat 2 which is in the form of a plane. The wireless transmitter 51 and the antenna 52 are connected by a guide. One end of the antenna 52 extends out of the shaft seat 2. When the video acquisition module completes the video acquisition, the video can be sent to the operating device 200 through the wireless transmitter 51. In the wireless transmitter, signal modulation is to convert the original electrical signal into a corresponding radio wave. This is achieved through modulation technology, such as frequency modulation, amplitude modulation or phase modulation. During the modulation process, the electrical signal will change the parameters of the radio wave so that it carries useful information.

[0043] A further embodiment of the battery pack 60 in the present invention: the battery pack 60 includes a through hole 61 arranged at the bottom of the axle seat 2, a battery seat 62 is fixed above the through hole 61 in the axle seat 2, a battery mounting groove 63 coaxial with the through hole 61 is provided at the bottom of the battery seat 62, a battery 64 is installed in the battery mounting groove 63, and a cover 65 that can close the through hole 61 is provided in the through hole 61. When the cover 65 is separated from the through hole 61, the battery 64 can be easily replaced. This is convenient to operate and is suitable for the rules for logistics troops to quickly maintain or repair equipment when the troops are performing tasks.

[0044] A further embodiment of the axle seat 2 in the present invention: a threaded sleeve 92 is provided at the end of the axle seat 2, and a screw 93 which can be threadedly connected to the threaded sleeve 92 is provided at one end of the plug-in shaft 3. The plug-in shaft 3 can be disassembled and replaced, and can be replaced with a plug-in shaft 3 of different lengths and diameters, so that it can be suitable for different models of artillery.

[0045] A further embodiment of the insertion shaft 3 in the present invention: a plurality of positioning holes 94 are sequentially arranged along the circumference on the outer wall of the insertion shaft 3, and positioning beads 95 are respectively arranged in the positioning holes 94. The positioning beads 95 can prevent the direct-aiming weapon zero-bullet calibration system from falling off by itself after the insertion shaft 3 is installed on the artillery.

[0046] A further embodiment of the axle seat 2 of the present invention is as follows: an indicator light 96 for indicating a working state is provided inside the axle seat 2 , and one end of the indicator light 96 extends out of the axle seat 2 .

[0047] A calibration method using any one of the above-mentioned direct-aiming weapon zero-bullet calibration systems comprises the following steps:

[0048] Step S1, insert the insertion shaft 3 into the connecting piece on the outer wall of the gun barrel, and the objective lens 21 on the inner wall of the lens barrel 1 will face the direction of the gun barrel firing;

[0049] Step S2, insert the battery 64 into the battery installation slot 63 and close the through hole 61 through the cover 65 to fix the battery 64, press the start switch 5 to connect the circuit between the battery pack 60 and the video acquisition module 40 and the video transmission module 50.

[0050] Step S3, capturing the distant target through the objective lens 21 and the prism lens 32 and projecting it onto the video acquisition module 40;

[0051] Step S4, the video acquisition module 40 acquires the target image captured by the objective lens 21 and the prism lens 32 and cooperates with the video acquisition module 40 to adjust the focal length of the shooting;

[0052] Step S5, the video transmitting module 50 transmits the image data of the video acquisition module 40 to the operating device, generates a crosshair of the target on the screen of the operating device, and observes whether the generated crosshair and the crosshair on the screen of the fire control system overlap and are aligned with the center of the target. If the crosshairs of the two screens are aligned with the center of the target, the adjustment is completed. If the crosshairs of the two screens are misaligned, the angle of the artillery needs to be calibrated.

[0053] When in use: The objective lens has high resolution and can identify tiny details in the sample. High resolution means that the image is clearer and can provide more sample information. The objective lens has a larger numerical aperture and can receive more light, thereby improving resolution and image quality. The larger the numerical aperture, the better the performance of the lens. A high-quality objective lens can control distortion well to ensure that the resulting image is true and accurate. This helps to obtain more reliable observations. The prism lens has a longer focal length: the prism lens can increase the focal length by reflecting the path of light, which is suitable for long-distance shooting and can capture details of more distant scenes. Since the optical zoom is completed inside the body, the prism lens is easier to install filters, which is very useful for shooting that requires specific filter effects. The prism lens avoids the "bellows" phenomenon that occurs when the traditional lens is zoomed by reflecting light, which helps to maintain the stability of the shooting. The video collector receives analog video signals from external devices through specific interfaces such as S-Video, Composite, HDMI, etc., and the collector is equipped with a prism lens. There is an analog-to-digital converter ADC in the part to convert the received analog signal into a digital signal. The converted digital video signal is usually compressed and encoded for storage and transmission. 1. Data transmission: The processed digital video signal is transmitted to the computer's memory through a computer bus such as PCI or PCIe. On the computer, the user can use professional video editing software to further process the captured video, such as editing, adding special effects, etc. When the video capture module completes the video capture, the video can be sent to the operating device 200 through the wireless transmitter 51. In the wireless transmitter, signal modulation is to convert the original electrical signal into a corresponding radio wave. This is achieved through modulation technology, such as frequency modulation, amplitude modulation or phase modulation. During the modulation process, the electrical signal will change the parameters of the radio waves so that they carry useful information. When the cover 65 is separated from the through hole 61, the battery 64 can be easily replaced, which is convenient for operation and suitable for the logistic troops to quickly maintain or repair the equipment when the troops are performing tasks. The plug shaft 3 can be disassembled and replaced, and can be replaced with a plug shaft 3 of different lengths and diameters, so that it can be suitable for different types of artillery.
