[0028] The utility model will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 6The illustrated zero-explosive calibration system for a direct-fire weapon includes a scope tube 1, a bearing 2 connected to the rear end of the scope tube 1, and a shaft 3 connected to one end of the bearing 2. The shaft 3 can be connected to a connector on the outer wall of the gun barrel.

[0030] A video acquisition module 40 is provided on the bearing 2 to acquire images captured by the lens group 10.

[0031] A video transmission module 50 is provided on the bearing 2 to transmit the images captured by the video acquisition module 40 to the operating device.

[0032] A battery pack 60 is provided on the bearing 2 to provide power to the video acquisition module 40 and the video transmission module 50. A start switch 5 is provided on the bearing 2.

[0033] The battery pack 60 includes a through hole 61 at the bottom of the bearing seat 2. A battery holder 62 is fixed above the through hole 61 inside the bearing seat 2. A battery mounting groove 63 coaxial with the through hole 61 is provided at the bottom of the battery holder 62. A battery 64 is installed in the battery mounting groove 63. A cover 65 is provided inside the through hole 61 to close 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 logistics troops to quickly maintain or repair the equipment when the troops are performing missions.

[0034] A further embodiment of the objective lens module 20 of this utility model: The objective lens module 20 includes an objective lens 21 disposed 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, which can connect with the first external thread 22, is provided on the inner wall of the lens barrel 1. The objective lens has high resolution, enabling it to identify minute details in the sample. High resolution means a clearer image, providing more sample information. A larger numerical aperture of the objective lens allows it to receive more light, thereby improving resolution and image quality. The larger the numerical aperture, the better the lens performance. A high-quality objective lens can effectively control distortion, ensuring that the obtained image is true and accurate. This helps to obtain more reliable observation results.

[0035] A further embodiment of the prism module 30 of this utility model: The prism module 30 includes an annular mounting groove 31 disposed at the end of the inner wall of the lens barrel 1. A prism lens 32 is embedded in the annular mounting groove 31. The prism lens has the following advantages: it can achieve a longer focal length. The prism lens can increase the focal length by reflecting the path of light, which is suitable for shooting at a distance and can capture more distant scene details. Since the optical zoom is completed inside the camera body, it is easier to install filters on the prism lens, which is very useful for shooting that requires specific filter effects. The prism lens avoids the "focus hunting" phenomenon that occurs when zooming with traditional lenses by reflecting light, which helps to maintain the stability of shooting.

[0036] A further embodiment of the video acquisition module 40 in this utility model: A groove 91 is provided on the inner wall of the flat surface of the bearing 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. The acquisition device has an analog-to-digital converter (ADC) inside, which converts the received analog signals into digital signals. The converted digital video signals are usually compressed and encoded for storage and transmission. Data transmission: The processed digital video signals are 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 and adding special effects.

[0037] A further embodiment of the video transmitting module 50 of this utility model: The video transmitting module 50 consists of a wireless transmitter 51 and an antenna 52. The wireless transmitter 51 is fixed on the planar inner wall of the bearing 2. The wireless transmitter 51 and the antenna 52 are connected by a guide. One end of the antenna 52 extends out of the bearing 2. After the video acquisition module has acquired the video, it can transmit the video to the operating device 200 through the wireless transmitter 51. In the wireless transmitter, signal modulation converts the original electrical signal into a corresponding radio wave. This is achieved through modulation techniques, such as frequency modulation, amplitude modulation, or phase modulation. During modulation, the electrical signal changes the parameters of the radio wave, enabling it to carry useful information.

[0038] A further embodiment of the shaft seat 2 of this utility model: a threaded sleeve 92 is provided at the end of the shaft seat 2, and a screw 93 that can be threadedly connected to the threaded sleeve 92 is provided at one end of the insert shaft 3. The insert shaft 3 can be disassembled and replaced, and can be replaced with insert shafts 3 of different lengths and diameters, so that it can be used for different types of artillery.

[0039] A further embodiment of the insert shaft 3 in this utility model: a plurality of positioning holes 94 are arranged in sequence along the circumference on the outer wall of the insert shaft 3, and positioning beads 95 are respectively provided in the positioning holes 94. The positioning beads 95 can prevent the zero bullet calibration system of the direct-fire weapon from falling off by itself after the insert shaft 3 is installed on the cannon.

[0040] A further embodiment of the bearing seat 2 of this utility model: an indicator light 96 for indicating the working status is provided in the bearing seat 2, and one end of the indicator light 96 extends out of the bearing seat 2.

[0041] In use: Objective lenses have high resolution, enabling the identification of minute details in samples. High resolution means sharper images, providing more sample information. Objective lenses have a larger numerical aperture, allowing them to receive more light, thus improving resolution and image quality. A larger numerical aperture generally results in better lens performance; high-quality objective lenses effectively control distortion, ensuring accurate and realistic images. This contributes to more reliable observation results. Prism lenses allow for longer focal lengths: prism lenses increase focal length by reflecting light, making them suitable for long-distance shooting and capturing more distant details. Because optical zoom is performed internally, prism lenses are easier to mount filters on, which is very useful for shooting requiring specific filter effects. Prism lenses avoid the "focus hunting" phenomenon that occurs with traditional lenses during zooming by reflecting light, contributing to stable shooting. The video capture unit receives analog video signals from external devices through specific interfaces such as S-Video, Composite, and HDMI. The device has an analog-to-digital converter (ADC) that converts the received analog signal into a digital signal. The converted digital video signal is usually compressed and encoded for storage and transmission. Data transmission: The processed digital video signal is transmitted to the computer's memory via 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 and adding special effects. After the video capture module finishes capturing the video, it can send the video to the operating device 200 via a wireless transmitter 51. In the wireless transmitter, signal modulation converts the original electrical signal into corresponding radio waves. This is achieved through modulation techniques such as frequency modulation, amplitude modulation, or phase modulation. During modulation, the electrical signal changes the parameters of the radio wave, enabling it to carry useful information. After the cover 65 is separated from the through hole 61, the battery 64 can be easily replaced. This makes operation convenient and is suitable for the logistics troops to quickly maintain or repair the equipment when the troops are performing missions. The insert shaft 3 can be disassembled and replaced with insert shafts of different lengths and diameters, so that it can be used for different types of artillery. The positioning bead 95 can prevent the zero-shot calibration system of the direct-fire weapon from falling off by itself after the insert shaft 3 is installed on the artillery.
