Abstract
Description
[Technical Field]
[0001] This invention relates to an image ranging and identification device; in particular, it discloses the structural form of an innovative image ranging and identification device applied to stun guns. [Previous Technology]
[0002] In terms of use, stun guns (also known as projectile stun guns) can paralyze a person for a certain period of time without any sequelae, and can effectively prevent situations where the military and police cause accidental injury or death due to excessive use of firearms. These advantages make stun guns a law enforcement weapon that is currently considered to be more in line with the ideal state and has low negative impact.
[0003] However, when using a stun gun to attack a human target, one should still avoid shooting dangerous areas such as the head, heart, eyes, and genitals. Repeated, prolonged, or continuous use of a stun gun may lead to cumulative fatigue, stress, and risks of cardiovascular, physiological, metabolic, and respiratory diseases, thereby increasing the risk of death or serious injury to the victim.
[0004] In the current conventional design of stun guns, although some models are equipped with chips to record basic information such as the date and time of shooting, when shooting human targets, if the aiming point is in a dangerous area, there is still a lack of a warning mechanism to warn the user in time to avoid dangerous shooting. Therefore, the use of conventional stun guns is still not perfect, which is an important technical issue that deserves the attention and breakthrough of the relevant industry. [Summary of the Invention]
[0005] The main objective of this invention is to provide an image ranging and recognition device and an electric shock gun using the same. The technical problem it aims to solve is to explore and innovate a new device and method with the goal of developing a more ideal and practical one.
[0006] Based on the aforementioned objective, the technical feature of the present invention in solving the problem mainly lies in that the image ranging and recognition device is specifically designed for attachment to an existing stun gun to perform real-time detection and warning of dangerous firing points on a target human body; the stun gun is equipped with a magazine for ejecting two stun firing needles; the image ranging and recognition device includes: an image capture unit for capturing an image of the target human body, the image of which must include an aiming point emitted by the stun gun; and a ranging unit for measuring the distance between the target human body and the image ranging and recognition device, thereby generating a firing signal. The device includes: a distance parameter; a dangerous firing point information storage unit for storing information on the range of dangerous firing points on the human body, used as a comparison parameter; a firing point spacing parameter storage unit for storing the firing point distribution spacing parameters of the two electric firing pins under various firing distance conditions, with the firing point distribution spacing parameter referenced from the aiming point during the firing; an image processing and computing unit electrically connected to the image capture unit, the ranging unit, the dangerous firing point information storage unit, and the firing point spacing parameter storage unit, used to perform edge computing on the image and integrate the firing distance parameter and the firing point distribution spacing parameter to calculate whether the impact point of the two electric firing pins is within the range of dangerous firing points on the human body, and if so, generating a warning signal; an alarm triggered by the warning signal, used to issue an alarm to alert the stun gun user; and a power supply module to provide the necessary power for the operation of each component of the image ranging and recognition device.
[0007] The main effect and advantage of this invention is that it can detect and warn of dangerous shooting points of the target human body in real time, thereby helping the user of the stun gun to avoid the dangerous shooting point range of the human body, and relatively improving the accuracy and safety of the use of the stun gun, which is particularly practical and progressive.
[0008] Another major objective of this invention is to provide an image ranging and recognition method specifically for stun guns, used for real-time detection and warning of dangerous firing points on a target human body; the stun gun is equipped with a magazine for ejecting two stun needles; the image ranging and recognition method includes: an image acquisition step to acquire an image of the target human body, the image containing an aiming point emitted by the stun gun; a ranging step to measure the distance between the target human body and the magazine of the stun gun, thereby generating a firing distance parameter; and a parameter storage step to store the target human body. The system stores information on the dangerous firing point area of the human body as a comparison parameter; and stores the firing point distribution spacing parameters of the two electric shock needles under various firing distance conditions, with the firing point distribution spacing parameters taking the aiming point at the time of firing as a reference; through an image processing and calculation step, edge calculation is performed on the image, and the firing distance parameters and the firing point distribution spacing parameters are integrated for calculation to estimate whether the landing point of the two electric shock needles is located within the dangerous firing point area of the human body. If so, a warning signal is generated; the warning signal triggers an alarm to issue an alarm to alert the user of the stun gun.
[0009] Another object of the present invention is to provide a stun gun, which includes a gun body, a grip, a muzzle and a trigger, wherein a magazine is provided at the muzzle for ejecting two stun needles; and wherein the stun gun also includes the aforementioned image ranging and recognition device, such that the image capture device of the image ranging and recognition device is aligned with the muzzle, so as to facilitate the capture of the image of the stun target human body.
Implementation Method
[0010] Please refer to Figures 1 to 4, which are preferred embodiments of the image ranging and identification device of the present invention and the stun gun using the same. However, these embodiments are for illustrative purposes only and are not limited to this structure in the patent application.
[0011] The image ranging and recognition device A is specifically designed to be attached to an existing stun gun 10 for real-time detection and warning of dangerous firing points of a human body 20 (as shown in Figure 3) targeted for stun. The stun gun 10 is equipped with a magazine 11 for ejecting two stun firing pins 12. The image ranging and recognition device A includes the following components: an image capturer 30 for capturing an image 31 of the human body 20 targeted for stun, the image 31 of which must include an aiming point C emitted by the stun gun 10. (As shown in Figure 5, typically a laser spot or infrared spot); a ranging unit 40, used to measure the distance between the electric shock target human body 20 and the image ranging and recognition device A, thereby generating a shooting distance parameter 41; a dangerous shooting point information storage unit 50, used to store information on the range of dangerous shooting points on the human body as a comparison parameter; a shooting point spacing parameter storage unit 60, used to store the shooting point distribution spacing parameter 61 of the two electric shock needles 12 under various shooting distance conditions, and the shooting point distribution spacing parameter 61 is referenced to the aiming point C at the time of shooting (as shown in Figure 4); an image processing and calculation unit 70, which, together with the image capturing... The image processing and computing unit 70 is electrically connected to the image 31, the ranging unit, the dangerous shooting point information storage unit, and the shooting point spacing parameter storage unit. The image processing and computing unit 70 is used to perform edge calculations on the image 31 and integrate the shooting distance parameter 41 and the shooting point distribution spacing parameter 61 to calculate whether the landing point of the two electric shock needles 12 is located within the range of the human body dangerous shooting point. If so, a warning signal 71 is generated. An alarm 80 is triggered by the warning signal 71 and is used to issue an alarm 81 to warn the user of the electric shock gun 10. A power supply module 90 is used to provide the power required for the operation of each component of the image ranging and recognition device A.
[0012] As shown in Figure 3, the information on the dangerous shooting point area of the human body is described above. The left and right figures are the front and back outlines of the human body, respectively. The head, heart, eyes and genitals of the human body are considered to be within the dangerous shooting point area by the relevant industry.
[0013] The specific content of the firing point distribution spacing parameter 61 mentioned above is shown in Figure 4. It is the firing point distribution spacing (e.g., 11cm, 30cm, etc.) of the two electric firing pins 12 under different firing distances (e.g., 1M, 4M, etc.). As can be seen from Figure 4, the firing point distribution spacing parameter 61 is based on the aiming point C during the firing. However, the actual landing point of the two electric firing pins 12 may be asymmetrical relative to the aiming point C. Of course, this part will vary depending on the design of the magazine mechanism.
[0014] The alarm 81 emitted by the alarm device 80 may be in any one of the following forms: sound (such as a buzzer), voice, or light signal.
[0015] In addition, the power supply module 90 is either a battery pack or an external power supply connection terminal (i.e., externally connected to the stun gun 10).
[0016] As shown in Figure 6, in this example, the firing point distribution spacing parameters stored in the firing point spacing parameter storage unit 60 include multiple sets of firing point distribution spacing parameters 61A, 61B, and 61C generated by different magazine angle specifications, so that the image ranging and identification device A further includes a magazine angle specification detection and identification module 100 (Note: used to detect the magazine type of the stun gun). The detection result generates a magazine angle signal 101 and gives it to the image processing and calculation unit 70 to capture the correct firing point distribution spacing parameters 61A, 61B, or 61C.
[0017] Through the above-described structural composition and technical features, the image ranging and identification device A disclosed in this invention can perform real-time detection and warning of dangerous shooting points on the target human body 20 (as shown in Figure 3), thereby assisting the stun gun user in avoiding the dangerous shooting point range of the human body, and relatively improving the accuracy and safety of the stun gun use. Among the key technical features of this invention, the dangerous shooting point information storage unit 50 can store information on the range of dangerous shooting points of the human body as a comparison parameter; the shooting point spacing parameter storage unit 60 stores the shooting point distribution spacing parameter 61 of the two stun guns 12 under various shooting distance conditions; then the image processing and calculation unit 70 performs edge calculation on the image 31, and integrates the shooting distance parameter 41 and the shooting point distribution spacing parameter 61 for calculation to estimate whether the landing point of the two stun guns 12 is located within the range of the dangerous shooting point of the human body. It is understandable that the present invention cleverly incorporates the firing point distribution spacing parameter 61 of the two electric shock needles 12. This part is crucial because it is a characteristic of the firing of the stun gun 10. Unlike ordinary firearms, which only form one firing point in each firing action, the stun gun 10 fires two electric shock needles 12. Therefore, this part must be included as a calculation parameter in order to achieve the purpose of accurate safety warning.
[0018] The present invention further provides an image ranging and identification method specifically for stun guns, for real-time detection and warning of dangerous firing points of a human body 20 to be stunned; the stun gun 10 is provided with a magazine 11 for ejecting two stun firing needles 12; the image ranging and identification method includes: (as shown in Figure 8, and please refer to Figures 5 to 7) an image capturing step S1 to capture an image 31 of the human body to be stunned, the image 31 including an aiming point C emitted by the stun gun 10; a ranging step S2 to measure the distance between the human body to be stunned and the magazine of the stun gun, thereby generating a firing distance parameter 41; a parameter storage step S3 to store information on the range of dangerous firing points of the human body as a comparison parameter; and to store the firing point distribution spacing parameter 61 of the two stun firing needles under multiple different firing distance conditions, and the firing point distribution spacing parameter 61 is based on the aiming point C at the time of firing. Through an image processing and calculation step S4, edge calculation is performed on the image 31, and the shooting distance parameter 41 and the shooting point distribution spacing parameter 61 are integrated and calculated to estimate whether the landing point of the two electric shock needles is within the range of the human body dangerous shooting point. If so, a warning signal 71 is generated; the warning signal 71 triggers an alarm 80 to issue an alarm (as shown in S5) to warn the user of the stun gun.
[0019] The firing point distribution spacing parameter 61 stored in the parameter storage step includes multiple sets of firing point distribution spacing parameters 61 generated by different magazine angle specifications, so that the image ranging and identification method further includes a magazine angle specification detection and identification module 100, the detection result of which generates a magazine angle signal 101, so that the image processing and calculation step captures the correct firing point distribution spacing parameter 61.
[0020] The present invention further provides an electric shock gun 10, as shown in Figures 1 and 2, which includes a gun body 13, a grip 14, a muzzle 15 and a trigger 16, wherein a magazine 11 is provided at the muzzle 15 for ejecting two electric shock needles 12; and wherein the electric shock gun 10 also includes the image ranging and recognition device A mentioned above, such that the image capture device 30 of the image ranging and recognition device A is aligned with the muzzle 15, so as to facilitate the capture of the image 31 of the electric shock target human body 20.
[0021] The image ranging and identification device A is detachably assembled on one side of the gun body 13 of the stun gun 10. (Note: preferably the top or bottom side.)
[0022] Furthermore, the image ranging and identification device A is attached to one side of the gun body 13 of the stun gun 10 in a fixed manner. (Note: The top or bottom side is preferred.) [Simplified Explanation of the Diagram]
