The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] An embodiment of the present invention provides a dual-band spot acquisition and identification device, comprising:

[0034] Target box housing 1;

[0035] The main control panel 2 is arranged inside the target box housing 1 and is located in the center;

[0036] The lighting lens 3 is arranged at the center of the main control board 2;

[0037] The target panel 4 is arranged at the front side of the target box housing 1 , corresponding to the position of the lighting lens 3 .

[0038] In this embodiment, a first LED light group and a second LED light group of different colors are integrated on the main control board 2 to illuminate the target panel.

[0039] In this embodiment, the first LED light group is a red light group 6, which is used to illuminate the positioning point on the back of the target panel 4 during the calibration process, and the second LED light group is a yellow light group 7, which is used to illuminate the target panel 4 during use.

[0040] In this embodiment, the device further includes:

[0041] The double narrow-band filter 5 is arranged at the bottom of the lighting lens 3 and is used to filter out the yellow light generated by the yellow light group 7 when a shooting light spot of a preset wavelength appears on the target panel 4 during use;

[0042] And, used during the calibration process, the red light generated by the red light group 6.

[0043] In this embodiment, the preset wavelength is 850 nm or 650 nm.

[0044] In this embodiment, the main control board 2 further includes:

[0045] The CCD sensor chip 10 is arranged on the main control board 2 and corresponds to the position of the light collecting lens 3, and is used to receive the image of the light spot landing point of the target panel 4;

[0046] Processing chip 8, used for calculating the light spot landing image;

[0047] The wireless transmission module 9 is used to upload the solution results.

[0048] In this embodiment, the target panel 4 is made of transparent acrylic material, with a target ring pattern sprayed on the front side and black paint sprayed on the back side, and unsprayed areas are left at the four corners of the back side.

[0049] In this embodiment, the positioning point pattern is white paint.

[0050] In this embodiment, a screw hole is provided in the middle of the target box housing 1 for fixing the main control board 2 ; a magnetic seat is provided on the front for attracting or disassembling the target panel 4 .

[0051] like Figures 1 to 4 As shown, the components of the device of the present invention mainly include a target box housing 1, a main control board 2, a lighting lens 3, and a target panel 4.

[0052] The main control board 2 is installed in the center of the target box housing, the lighting lens 3 is installed in the middle of the main control board 2, and the target panel 4 is installed on the front of the target box housing 1.

[0053] The main control board 2 is equipped with a group of red high-brightness LED lights 6 and yellow high-brightness LED lights 7, and the bottom of the lighting lens 3 is equipped with a dual narrow-band filter 10 of 850 and 650 nm. The front of the target panel 4 is printed with a target ring pattern that meets the standard size of the international sports air gun target, and the back is printed with a positioning point for identifying the type of the target surface. The red high-brightness LED light 6 is used to illuminate the positioning point during calibration, and the yellow high-brightness LED light 7 is used to illuminate the target surface during use. During the calibration process, the main control board 2 controls the high-brightness red LED light 6 to illuminate the target surface, and turns off after the positioning point is identified and the calibration is successful; during use, when a shooting light spot of 850 or 650 nm appears on the target panel, the target surface image is obtained by the main control board 2 through the lighting lens 3. Because the dual narrow-band filter 10 is installed, the high-brightness yellow lighting light inside the target box is filtered out, and the 850 or 650 nm light spot can be accurately identified in the acquired image. The main control board 2 can accurately identify and calculate the light spot position by running the algorithm, and upload the calculation result to the display terminal. The high-brightness yellow LED light can illuminate the target surface normally, allowing the shooter to see clearly at the shooting position.

[0054] In Example 1, the target box housing 1 is used to receive the outer shell of the target device, and a screw hole is set in the middle of the interior for fixing the main control board; a magnetic suction seat is set on the front for sucking or disassembling the target panel.

[0055] In Example 1, the main control board 2 is equipped with red and yellow high-brightness LED lights (6 and 7), CCD sensor chip 10, processing chip 8, wireless transmission module 9 and other devices, wherein the red high-brightness LED light 6 is used to illuminate the target surface positioning point during calibration, the yellow high-brightness LED light 7 is used to illuminate the target surface, the CCD sensor chip 10 is used to receive the image signal, the processing chip 8 is used to solve the image signal, and the wireless transmission module 9 is used to upload the solution result. The device needs to be calibrated before use. During calibration, the main control board 2 controls the red high-brightness LED light 6 to light up, thereby illuminating the positioning point pattern on the back of the target panel. The positioning point image signal is received by the CCD sensor chip 10 after passing through the lighting lens 3, and then transmitted to the processing chip 8 for solution processing, identifying the type of the positioning point and obtaining its initial position. The initial position data is used as a reference for subsequent identification of the laser spot position. When the laser spot landing point image is collected, the position coordinates of the spot landing point are solved according to the position of the positioning point, and the target judgment ring value is solved, and finally the ring value data is uploaded to the display terminal through the wireless transmission module 9.

[0056] In Example 1, the lighting lens 3 is installed above the CCD sensor chip 10 in the middle of the main control board 2, facing the back of the target panel 4 installed on the front side of the target box shell 1, and is used to collect the positioning point on the back of the target panel 4 and the image of the laser spot landing point transmitted to the back. 850 and 650nm dual narrow-band filters 5 are installed at the bottom of the lighting lens 3. When the device enters the calibration process, the red high-brightness LED light 6 on the main control board lights up and emits 650nm red light. After the light hits the positioning point on the back of the target panel, it is reflected and enters the lighting lens 3. Because the dual narrow-band filter 5 can pass 650nm red light, the CCD sensor chip 10 on the main control board can normally receive the positioning point image signal on the back of the target panel 4; when the device enters the normal use process, the 650 or 850nm shooting laser hits the target surface. A light spot is formed on the front of the plate 4, and the light spot is transmitted to the back of the target panel 4, then a light spot image is formed on the back of the target panel 4. At the same time, the yellow high-brightness LED light 7 will light up to illuminate the target surface during use, so the lighting lens can collect the high-brightness yellow background light and the light spot image, but the dual narrow-band filter 5 can filter out light other than 850 and 650nm, so the high-brightness yellow background light will be filtered out, and only the laser spot image of 650 or 850nm can pass through the filter into the CCD sensor chip, which can ensure that the laser spot signal can be accurately collected.

[0057] The target panel 4 is made of transparent acrylic material, and a target ring pattern that meets the ISSF standard is sprayed on the front for shooters to aim and shoot. A layer of black paint is sprayed on the back to reduce the influence of the reflection of the yellow high-brightness LED light on the acquisition of the spot image. There are unsprayed areas at the four corners of the back, and the positioning point pattern printed on the front can be transmitted to the back through this area. The target panel type can be distinguished by the positioning point pattern, and the main control board 2 can determine its own type by identifying the positioning point pattern. Among them, the positioning point pattern is white paint, which is more conducive to the illumination of 650nm light during the calibration process, and is convenient for calibration and positioning.

[0058] Compared with the prior art, this embodiment has at least the following effects:

[0059] 1) The target surface is illuminated by internal lighting. The target panel is illuminated by an internal high-brightness yellow LED lighting lamp, so that the front of the target panel reaches sufficient brightness, eliminating the complex external light frame structure. The shooter can clearly see the target ring pattern on the target surface when aiming at the shooting position.

[0060] 2) Use dual narrow-band filters to filter out interfering light other than 850 and 650nm. Use a single light-collecting lens and filter to achieve accurate collection of 850 or 650nm shooting laser spots, which can save costs.

[0061] 3) Double narrow-band filters are used to filter out interference light other than 850 and 650nm, ensuring the high transmittance of 850 and 650nm effective laser signals, which can ensure that the effective light spot image is clearer, effectively improve the accuracy of light spot landing point recognition, and improve the efficiency of shooter training.

[0062] Through the description of the specific implementation methods, a deeper and more specific understanding of the technical means and effects adopted by the present invention to achieve the predetermined purpose should be obtained. However, the accompanying drawings are only for reference and illustration purposes and are not intended to limit the present invention.
