[0027] The present invention is further described below in conjunction with embodiments and drawings. Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the gun aiming detection device 100 includes a first bracket 102, a second bracket 103 and a third bracket 101. Two first clamping devices 104 are arranged on the third bracket 101. The two first clamping devices 104 are used to clamp the main body of the gun 200 to fix the gun 200. The structure of the first clamping device 104 can adopt the existing technology, which is not repeated here. The first bracket 102 and the second bracket 103 are both movably connected to the third bracket 101. In the example shown in the figure, the first bracket 102 and the second bracket 103 can be lifted and lowered and can be arranged to be laterally movable. According to the scheme of the utility model, a guiding device can also be arranged, such as a guide rail matched with a slider, to guide the movement of the first bracket 102 and the second bracket 103. The movement of the first bracket 102 and the second bracket 103 can be manual, and a motor is also arranged to drive the first bracket 102 and the second bracket 103 to move, so as to achieve automatic control. The first bracket 102 and / or the second bracket 103 are arranged on a slider, and the slider can slide along the guide rail, so as to realize the lifting and / or lateral movement of the first bracket 102 and / or the second bracket 103.

[0029] The first bracket 102 is provided with a first light source 111 and a first curtain 121. The first light source 111 and the first curtain 121 are arranged at intervals. When the first bracket 102 moves, the first light source 111 and the first curtain 121 can be moved to both sides of the front sight 201, and the first curtain 121 is located between the front sight 201 and the muzzle. The first light source 111 illuminates the front sight 201, so that the front sight 201 forms a first projection on the first curtain 121.

[0030] The second bracket 103 is provided with a second light source 112 and a second curtain 122. The second light source 112 and the second curtain 122 are arranged at intervals. When the second bracket 103 moves, the second light source 112 and the second curtain 122 can be moved to both sides of the peephole 202, and the second curtain 122 is located between the peephole 202 and the muzzle. The second light source 112 illuminates the peephole 202, so that the peephole 202 forms a second projection on the second curtain 122. In the present embodiment as shown in the figure, the peephole 202 is hole-shaped.

[0031] The gun aiming detection device 100 in the utility model further includes a gun barrel center beam device 130, which is inserted into the gun barrel and emits a laser line or a light beam constrained into a line. The gun barrel center beam device 130 includes a laser head 131 for emitting light and an insertion part 132 for inserting into the gun barrel; the laser head 131 and the insertion part 132 are integrally formed. The insertion part 132 is provided with a receiving groove 1321. Blind holes 1322 are respectively provided at both ends of the receiving groove 1321. Both ends of the elastic wire 133 are respectively inserted into the blind holes 1322. The elastic wire 133 is elastically deformed, and the middle part is arched and elastic. The insertion part 132 adopts the gauge size of the gun barrel 203. After the insertion part 132 is inserted into the gun barrel 203, the elastic wire 133 is squeezed by the inner wall of the gun barrel 203, so that the insertion part 132 is in close contact with the inner wall of the gun barrel 203. In the preferred embodiment of the utility model, the elastic wire 133 is located at the upper part, so that the elastic wire 133 is pressed by the upper part of the inner wall of the barrel 203, the insertion part 132 is kept in the barrel 203, and the center line of the insertion part 132 is coincident with or parallel to the center line of the barrel 203. Due to the provision of the elastic wire 133, the elasticity of the elastic wire 133 makes the center line of the insertion part 132 coincide with or remain parallel to the center line of the barrel 203. Moreover, even if the center lines of the two do not coincide, the maximum distance (error) between the two is equal to the tolerance of the muzzle diameter; for the subsequent use of the muzzle center beam or laser line instead of the muzzle axis as the reference line for measuring the position of the front sight and the peephole, the error can also meet the requirement of being negligible.

[0032] In the present invention, the brightness of the laser line or the central beam emitted by the barrel central beam device 130 is higher than the brightness of the light emitted by the first light source 111 and the second light source 112. In this embodiment, the barrel central beam device 130 is a laser light source that emits laser.

[0033] A prism group 140 is provided in front of the gun barrel 203. The prism group 140 is used to fine-tune the height and deflection angle of the central light beam, and is used to reflect the central light beam or laser line of the gun barrel onto the first curtain 121 and the second curtain 122. The prism group 140 is used in combination of two right-angle prisms. One of the right-angle prisms is located on the path of the light emitted by the central light beam device 130 of the gun barrel and reflects the laser line and the central light beam to the other right-angle prism, and the other right-angle prism reflects the laser line or the central light beam to the top of the gun body. After being reflected by the prism group 140, the laser line or the central light beam is irradiated toward the front sight 201 or the peephole 202, forming a bright spot on the first curtain 121 or the second curtain 122. When the first curtain 121 and the first light source 111 are used, the bright spot and the first projection are respectively located on the front surface and the rear surface of the first curtain 121. When the second light source 112 and the second screen 122 are used, the bright spot and the second projection are located on the front surface and the rear surface of the second screen 122 respectively.

[0034] The gun aiming detection device 100 of the present invention is also provided with a first camera 141 and a second camera 142. The first camera 141 is used to photograph the bright spot on the first curtain 121 and the first projection of the sight 201. The second camera 142 is used to photograph the bright spot on the second curtain 122 and the second projection of the peephole 202.

[0035] The first camera 141 captures the bright spot on the first curtain 121 and the first projection of the crosshair 201 to form an image. The image is transmitted to the control device, and the control device can determine whether the position of the crosshair 201 is correct by analyzing the positional relationship between the bright spot and the first projection of the crosshair 201. For example, by analyzing the relative position of the bright spot and the center point of the first projection of the crosshair 201, it can be determined whether the position of the crosshair 201 is correct. If the position of the crosshair 201 is incorrect, the offset of the two can be calculated based on the image to adjust the position of the crosshair 201. In the same principle, it is also possible to detect whether the position of the peephole 202 is correct and how to adjust the position of the peephole 202. The first camera 141 and the second camera 142 are both connected to the control device (not shown in the figure) for communication. The first camera 141 and the second camera 142 transmit the captured images to the control device, and the control device uses a program to calculate the position offset of the crosshair 201 and the position offset of the peephole 202. Example 2

[0036] The difference between this embodiment and embodiment 1 is that only one screen and one camera are provided, and the screen is located in front of the muzzle, that is, the position of the prism group 140 in embodiment 1. The prism group 140 is not provided in this embodiment. The laser line or laser beam emitted by the central beam device 130 of the barrel is irradiated on the screen to form a bright spot. The first light source 111 irradiates the sight 201, so that the sight 201 forms a first projection on the screen. The second light source 112 irradiates the peephole 202, so that the peephole 202 forms a second projection on the screen. The camera is used to illuminate the bright spot on the screen and the first projection and / or the second projection to form an image. By analyzing the relative position of the bright spot and the first projection on the image, and the relative position of the bright spot and the second projection, the position accuracy of the aiming mechanism can be analyzed. Analyzing whether the relative positions of the three are accurate can provide a data basis for adjusting the position of the aiming mechanism.

[0037] The utility model also provides a gun aiming detection method, which comprises the steps of:

[0038] A gun barrel center beam device is provided, so that the gun barrel center beam device emits a laser line or a center beam that coincides with or is parallel to the axis of the gun barrel, and forms a bright spot on the curtain through a fixed reflection light path;

[0039] Providing a backlight source, the backlight source irradiates the sight and / or the peephole, so that the sight forms a first projection on the screen, and the peephole forms a second projection on the screen;

[0040] Shoot the bright spot, the first projection and / or the second projection on the screen;

[0041] The positions of the bright spot and the first projection and / or the second projection are analyzed to determine the position offset of the sight or the peephole.

[0042] According to one embodiment of the utility model, the laser line or the center light beam is projected onto the same screen as the projection of the sight or the peephole after reflection; the relative position of the bright spot and the projection of the sight or the peephole can be obtained by shooting the image on the screen at the same time, which is used to calculate and analyze the relative offset.

[0043] The gun aiming detection device and detection method of the utility model utilizes a gun barrel center beam device to simulate the route of bullet shooting to emit a laser line or a center beam, and form a bright spot on the screen. The projection formed by irradiating the front sight or peephole by a backlight source is used. By analyzing the positional relationship between the bright spot and the projection, it is judged whether the position of the aiming mechanism is correct and the offset. The utility model utilizes a prism group to reflect the laser line or the center beam and the projection formed by irradiating the front sight or peephole to form a bright spot on the same screen, so that the relative position of the bright spot and the projection of the front sight or peephole can be analyzed and calculated more intuitively, and the captured image is easier to analyze. The different light intensities emitted by the gun barrel center beam and the backlight source make it easier to distinguish the difference in the projection position formed by the two, and it is easier to analyze and judge. An elastic wire is arranged on the gun barrel center beam, and the elasticity of the elastic wire can be used to press against the insertion part, so that the center line of the insertion part coincides with the center line of the gun barrel or remains parallel. Even if the two do not coincide, the spacing can be controlled within the allowable error range. The utility model can detect whether the position of the gun aiming mechanism is correct without live ammunition shooting. It can be automatically operated for detection, and the position of the front sight and peephole can be manually adjusted according to the deviation displayed by the computer, and re-checked until the calibration mechanism adjusts the aiming mechanism to the correct position. The cold aiming calibration device of the utility model has low detection cost and is easy to operate. The utility model innovatively applies the offset calculated by image analysis to manual adjustment of the front sight and peephole, or automatic adjustment of the mechanical servo mechanism, and re-checking of the accuracy after adjustment. And innovatively provides a method for accurately measuring and analyzing the height and inclination angle of the front sight relative to the central axis of the muzzle; and a method for accurately measuring and analyzing the left and right offset and height difference of the peephole relative to the central axis of the muzzle. The insertion part is provided with a receiving groove, and the two ends of the elastic wire are inserted into the blind holes at the two ends of the receiving groove. The receiving groove can keep the elastic wire firm and prevent the elastic wire from being skewed and ineffective when it is compressed.
