Description

Technical Field

[0001] This invention belongs to the technical field, and in particular relates to a method and system for evaluating shooting training efficiency. Background Technology

[0002] In military shooting training and student military training shooting assessments and competitions, live-fire training is the primary method. This is not only highly dangerous and costly, but also lacks the reliability and impartiality of traditional manual target reporting. To respond to the call for "technology-driven military training" and to save significant unnecessary military expenditures, it is essential to develop a simulation system that can conduct simulated shooting training under non-live-fire conditions, tailored to the actual needs of the armed forces. In recent years, with the continuous advancement of science and technology, especially the rapid development of optoelectronic technology, using lasers to replace actual bullets for shooting training has become a tool for reserve forces, school military training, and outdoor recreation. Summary of the Invention

[0003] The purpose of this invention is to provide a method and system for evaluating shooting training efficiency. By using a dual-point recording method to statistically analyze the results of laser simulation training, trainees can intentionally control the stability of the laser simulation training gun and improve the training effect.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a method for evaluating shooting training efficiency, comprising the following steps:

[0006] Step 1: The projection device projects the target image onto the target plate surface according to the selected mode;

[0007] Step two: The camera device records the target surface image and laser dots on the target plate.

[0008] Step 3: Calculate the target scores;

[0009] Step four: Evaluate the efficiency of shooting training based on the scores;

[0010] During target practice, the laser-simulated firearm fires two beams at intervals of one shot, with an interval of no more than 0.5 seconds.

[0011] Preferably, the two laser points captured by the photographic device in a single shot are considered as a set of data, and the target score is calculated by taking the position data of the first laser point in the data set.

[0012] Preferably, the shooting training stability of the laser-simulated firearm is analyzed by the distance between the light spots in the data set.

[0013] Preferably, the target firing modes include static target firing and target firing with varying target images.

[0014] Preferably, when shooting at a target with changing target images, the camera device starts and stops along with the projection device. If the camera device only captures a single light spot on the target surface in a single shot, the secondary light spot in a single shot is treated as a miss.

[0015] Preferably, the laser-simulated firearm fires two beams at a single firing interval for standing and kneeling firing positions.

[0016] A shooting training efficiency evaluation system includes:

[0017] The firing mode unit includes a static target module and a dynamic target module.

[0018] The projection unit is used to project target information onto the target plate surface.

[0019] The target surface imaging and capture unit includes a camera module, a recognition module, and a follow-up response module.

[0020] Among them, the camera module is used to capture target surface images, the recognition module is used to recognize target surface images with light spots, and the follow response module is used to activate the target surface capture unit when the unit projection unit is working.

[0021] The calculation unit is used to calculate the firing score of the laser gun.

[0022] Preferably, the static target module is used to control the projection unit to continuously project a static image of a target surface onto a certain area of ​​the target surface without moving.

[0023] The dynamic target module is used to control the projection unit to project static images onto the target surface intermittently or continuously.

[0024] Preferably, the calculation unit further includes calculating the score based on the first light spot of a single shot and calculating the gun holding stability based on the second light spot of a single shot.

[0025] Preferably, if the second light spot of a single shot is not captured within the interval between shots, it is treated as a missed target during the undetermined calculation.

[0026] The present invention has the following beneficial effects:

[0027] This invention uses a laser training gun to emit laser beams instead of real bullets for target practice. The accuracy of hitting the target with the laser training gun is evaluated, and the number of hits is used for integrated training. The two laser points captured by the photographic device in a single shot are used as a set of data. The position data of the first laser point in the data set is used to calculate the target score. The distance between the second laser point and the first laser point in a single shot is calculated, and the difference is used to evaluate the stability at the time of firing, thereby evaluating the training efficiency of shooting practice.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1 As shown, a laser training gun is used to emit laser beams instead of real bullets for target practice. The accuracy of the laser training gun's shots hitting the target is evaluated. The laser training gun used has simulated recoil. This invention is a method for evaluating the efficiency of shooting training. It mainly uses integrated training on the number of shots hit by the laser training gun and evaluates the stability when firing, thereby evaluating the training efficiency of shooting training.

[0037] The steps are as follows: turn on the projection device on the training target board, select the training mode, configure the firearm, and determine whether it is a standing or kneeling shooting position.

[0038] The projection device projects the target image onto the target plate surface according to the selected mode;

[0039] The camera device records the target surface image and laser dots on the target plate;

[0040] Calculate the target scores;

[0041] Shooting training efficiency is assessed based on scores;

[0042] During target practice, the laser simulated firearm emits two beams at intervals of no more than 0.5 seconds per shot. Preferably, the two laser points captured by the camera device in a single shot are considered as a set of data. The score is calculated based on the position data of the first laser point in the data set. If the first laser point in a single shot is outside the target image, it is treated as zero points or a miss during the calculation. If the second laser point is not on the target image, it is treated as a miss.

[0043] Preferably, the shooting training stability of the laser-simulated firearm is analyzed by the distance between the light spots in the data set. Specifically, the evaluation is performed based on the distance between the secondary light spot and the primary light spot during each shot.

[0044] Preferably, the target firing modes include static target firing and target firing with varying target images.

[0045] The laser-simulated firearm fires two beams at a time interval in a single shot, suitable for both standing and kneeling shooting positions.

[0046] Specific examples Figure 2 and Figure 4 As shown, select the static target image firing mode.

[0047] The target image is projected onto the target plate. Preferably, the target surface is a ring target. When calculating the score, a two-dimensional coordinate system is established with the center point of the ring target image as the origin on the left.

[0048] The camera device is activated after the projection device is turned on, recording the image on the target plate. Specifically, when the laser training gun fires a laser beam, the camera device captures the position information of the spot where the beam hits the target surface.

[0049] After firing, information with light spots is selected using image recognition methods. Specifically, the selection is based on the time recorded by the camera device, and light spot images with an interval of no more than 0.5 seconds are selected as a group. The distance between the two is calculated, and the stability of holding the gun during firing is calculated based on the distance. The photo with the earlier time in each group is the score information.

[0050] When calculating the score for static shooting of the target image, the score obtained from the first spot is directly added together.

[0051] Preferably, when firing at a target with changing image on the target surface, the camera device starts and stops simultaneously with the projection device. If the camera device only captures a single light point on the target surface in a single shot, the secondary light point of that single shot is treated as a miss. The miss point is calculated based on the distance between the first or second point on the outermost circle corresponding to the first shot. If both the first and second points miss, the diameter of the outermost circle is used, specifically as follows: Figure 4 The first shot is marked with point A1 and the second with point A2. The second shot is marked with point B1 and the second with point B2. The third shot is marked with point C1 and the second with point C2. The fourth shot is marked with point D1 and the second with point D2. The fifth shot is marked with point E1 and the second with point E2. The target score is the sum of the ring numbers of points A1, B1, C1, D1, and E1.

[0052] Stability of holding the gun during firing is achieved through... Calculate homogeneity, where X i For A n and A n+1 The greater the distance between them, the worse the stability of the homogeneous material.

[0053] In addition, the static target shooting mode of the target image can be trained by two people at the same time. When performing light spot image recognition, only the information in a certain target image needs to be recognized.

[0054] Specific examples Figure 3 and Figure 5 As shown, this is a target shooting exercise with changes in the target surface image.

[0055] The projection device intermittently and randomly projects a set of target images onto the target surface. This projection is intermittent and arbitrary, and the projection area is within the target plate. Specifically, as shown... Figure 5 As shown, the target images are projected sequentially from left to right on the target surface.

[0056] When the target image is projected, the coordinate axis established for that shot moves along with the target image.

[0057] Images containing target points were selected.

[0058] During actual shooting training, the camera device is activated after the projection device is turned on to record the image on the target board. That is, when the laser training gun fires a laser beam, the camera device captures the position information of the light spot that hits the target surface. The camera device records the time the target image remains on the target surface.

[0059] After firing, information with light spots is selected using image recognition methods. Specifically, the selection is based on the time recorded by the camera device, and light spot images with an interval of no more than 0.5 seconds are selected as a group. The distance between the two is calculated, and the stability of holding the gun during firing is calculated based on the distance. The photo with the earlier time in each group is the score information.

[0060] When calculating the score for static shooting of the target image, the score obtained from the first spot is directly added together.

[0061] Preferably, when firing at a target with changing image on the target surface, the camera device starts and stops simultaneously with the projection device. If the camera device only captures a single light point on the target surface in a single shot, the secondary light point of that single shot is treated as a miss. The miss point is calculated based on the distance between the first or second point on the outermost circle corresponding to the first shot. If both the first and second points miss, the diameter of the outermost circle is used, specifically as follows: Figure 5 The first shot's initial point is A5, the second point is A6; the second shot's initial point is B5, the second point is B6; the third shot's initial point is C5, the second point is C6; the fourth shot's initial point is D5, the second point is D6; and the fifth shot's initial point is E5, the second point is E6. The target score is the sum of the ring numbers corresponding to points A5, B5, C5, D5, and E5.

[0062] Stability of holding the gun during firing is achieved through... Calculate homogeneity, where X i For A n and A n+1 The greater the distance between them, the worse the stability of the homogeneous material.

[0068] The calculation unit is used to calculate the firing score of the laser gun.
