Description

Technical Field

[0001] This invention relates to the field of information collection equipment technology, and specifically to a facial recognition device suitable for information collection. Background Technology

[0002] Facial recognition is a biometric technology that identifies individuals based on their facial features. It involves using cameras or webcams to capture images or video streams containing faces, automatically detecting and tracking faces in the images, and then performing facial recognition on the detected faces.

[0003] Currently, a device is available on the market that can effectively record facial information at any time when police officers are on duty. During the information recording process, the camera and the face must remain still. This allows for faster information recording for drunk drivers and criminals who are uncooperative. Furthermore, by adjusting the transmission device, it can be used for people with different head sizes, and it can also effectively and quickly record the information of children with ADHD.

[0004] In existing technology, the face and camera are positioned correspondingly using a semi-circular plate. When the user's head moves significantly, the semi-circular plate will rotate significantly along with the camera. The clamping of the semi-circular plate will cause discomfort to the user, and clamping the user's head and chin will affect the overall capture effect of the user's face. Consequently, the camera pixels cannot capture the face effectively, resulting in poor capture quality. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the existing face recognition device cannot adjust the interval between the camera and the face when the face is fixed, resulting in poor acquisition effect, so as to provide a face recognition device suitable for information acquisition that can optimize the acquisition effect.

[0018] The technical solution of this invention has the following advantages:

[0019] 1. The facial recognition device suitable for information collection provided by this invention includes a clamping and limiting module with a first and second fixing block that rotates relative to each other to clamp and fix the head of the user. A camera module is positioned on the concave side of the horizontal limiting module, facing the user's face to collect facial information. The clamping and limiting module fixes the user's head, preventing incomplete information collection due to user movement. A spacing adjustment module adjusts the distance between the horizontal limiting module and the clamping and limiting module. After the distance is adjusted, two abutting protective blocks in the horizontal limiting module extend outwards to limit the left and right sides of the user's head. The camera module then collects the user's facial information. Fixing the user's head using the clamping and limiting modules prevents incomplete or failed facial information collection due to user movement during the camera module's facial information collection process. Furthermore, adjusting the distance between the horizontal limiting module and the clamping and limiting module facilitates the camera module's focusing on the user's face, further improving the efficiency of facial information collection. The facial recognition device proposed in this invention is suitable for information collection. It can fix the head of the person being detected, effectively optimize the facial information collection effect, and improve the collection efficiency.

[0020] 2. The facial recognition device suitable for information collection provided by the present invention sets a foldable protective airbag in the cavity of the horizontal limiting module. As the protective block extends to both sides, the foldable protective airbag expands and extends to both sides along with the protective block to abut against both sides of the tester's head, preventing the tester's head from shaking. The foldable protective airbag can effectively improve comfort and enhance safety and reliability.

[0021] 3. The component provided by the present invention is suitable for facial recognition devices for information collection. By pushing the component, the protective block is slid to both ends, while providing positive pressure inflation for the folding protective airbag. The elastic telescopic component provides a reset function, improving the ease of operation.

[0022] 4. The component provided by the present invention is suitable for a facial recognition device for information collection. A magnetic suction component is provided on the top of the main structure, and the bottom of the main structure and the push block are magnetically connected. Since the elastic telescopic component provides an upward thrust, the magnetic connection can avoid long-term pressing and free up labor.

[0023] 5. The component provided by this invention is suitable for a facial recognition device for information collection. The screw and the fixed rod are threadedly connected. By turning the screw, the round shaft block is driven to move in the vertical direction, thereby driving the first fixed block and the second fixed block to move in the vertical direction. This is suitable for adjusting the head height of the person being detected, so that the camera module is opposite to the head of the person being detected, optimizing the collection effect and improving versatility.

[0024] 6. The components provided by the present invention are suitable for facial recognition devices for information collection. Both the first fixing block and the second fixing block are arc-shaped to accommodate the head of the person being tested, thereby improving comfort. The arc-shaped elastic limiting structure provides a reset function for the first fixing block and the second fixing block, thereby improving the ease of operation.

[0025] 7. The components provided by this invention are suitable for facial recognition devices for information collection. The spacing adjustment module includes a first telescopic unit, a second telescopic unit, and a rotating joint for connecting the first telescopic unit and the second telescopic unit. The rotating joint improves the flexibility of the spacing adjustment module. By adjusting the angle between the first telescopic unit and the second telescopic unit through the rotating joint, a large spacing adjustment can be achieved. By adjusting the telescopic extension and retraction of the first telescopic unit and the second telescopic unit themselves, a small spacing adjustment can be achieved, thereby improving the adjustment accuracy, optimizing the effect of facial information collection, and improving the efficiency of facial information collection.

[0026] 8. The components provided by this invention are suitable for facial recognition devices that collect information. By connecting the information collection terminal to the main structure through a stabilizing rod, an integrated setup is achieved, improving convenience.

[0027] 9. The component provided by the present invention is suitable for a facial recognition device for information collection.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Reference Figures 1 to 2 As shown, the present invention proposes a facial recognition device suitable for information collection, comprising: a horizontal limiting module 1, a clamping limiting module 3, a spacing adjustment module 2, and a camera module 4. The horizontal limiting module 1 includes a main structure 11, which is arc-shaped. Both ends of the main structure 11 are provided with anti-collision protective blocks 12, which can extend along both sides of the main structure 11 to limit the left and right sides of the subject's head. The clamping limiting module 3 includes a first fixing block 31 and a second fixing block 32 movably connected. Block 31 and the second fixing block 32 rotate relative to each other to clamp and fix the head of the tester; one end of the spacing adjustment module 2 is hinged to the main structure 11, and the clamping limiting module 3 is connected to the other end of the spacing adjustment module 2. One end of the spacing adjustment module 2 rotates relative to the horizontal limiting module 1 to adjust the height position of the clamping limiting module 3. The spacing adjustment module 2 extends and retracts to adjust the spacing between the horizontal limiting module 1 and the clamping limiting module 3. The camera module 4 is located on the concave side of the main structure 11 and is suitable for collecting facial information of the tester.

[0040] Specifically, the first fixing block 31 and the second fixing block 32 in the clamping and limiting module 3 rotate relative to each other to clamp and fix the head of the tester. A camera module 4 is provided on the concave side of the horizontal limiting module 1. The camera module 4 is an infrared camera. The camera module 4 is located in the middle of the concave side of the horizontal limiting module 1 so as to face the face of the tester and collect the face information of the tester.

[0041] After the clamping and limiting module 3 fixes the subject's head to prevent the subject from shaking and causing incomplete information collection, the spacing adjustment module 2 adjusts the spacing between the horizontal limiting module 1 and the clamping and limiting module 3. After the spacing is adjusted, the two anti-collision protective blocks 12 in the horizontal limiting module 1 extend outward to limit the left and right sides of the subject's head. Finally, the camera module 4 collects the subject's facial information.

[0042] The device uses clamping and limiting module 3 and horizontal limiting module 1 to fix the subject's head, preventing incomplete or failed facial information acquisition due to subject movement during the facial information acquisition process. Furthermore, the spacing adjustment module 2 adjusts the distance between the horizontal limiting module 1 and clamping and limiting module 3, facilitating the camera module 4's focusing on the subject's face and further improving the efficiency of facial information acquisition. This invention provides a facial recognition device suitable for information acquisition that can fix the subject's head, effectively optimizing facial information acquisition and improving acquisition efficiency.

[0043] It is understandable that when the subject's head is fixed by the horizontal limiting module 1 and the clamping limiting module 3, the camera module 4 remains relatively stationary with respect to the subject's face, thereby improving the acquisition effect of facial information.

[0044] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the main structure 11 has a cavity inside, and the horizontal limiting module 1 also includes a folded protective airbag 14 disposed in the cavity. One end of the folded protective airbag 14 is connected to the inner wall of the cavity, and the other end of the folded protective airbag 14 is connected to the abutment protection block 12. The main structure 11 has an air inlet that communicates with the folded protective airbag 14.

[0045] Specifically, the main structure 11 has an internal cavity, and a foldable protective airbag 14 is installed inside the cavity. One end of the foldable protective airbag 14 is connected to the inner wall of the cavity, and the other end is connected to the protective blocks 12. An air inlet is provided on the main structure 11, which is connected to the foldable protective airbag 14. When the two protective blocks 12 slide to the sides, they cause the foldable protective airbag 14 to expand. Gas enters the foldable protective airbag 14 from the air inlet to inflate it. After inflating, the foldable protective airbag 14 extends to both sides along with the protective blocks 12 to press against the sides of the tester's head, preventing the tester's head from shaking. This foldable protective airbag 14 can effectively improve comfort and enhance safety and reliability.

[0046] One end of the folded protective airbag 14 is connected to the inner wall of the cavity, thereby ensuring the stability of the installation of the folded protective airbag 14, preventing the folded protective airbag 14 from detaching from the cavity, and ensuring the stability of the structure.

[0047] It should be noted that there are two of each of the cavity, the folded protective airbag 14, and the impact protective block 12, and they are symmetrically distributed.

[0048] Reference Figure 3 As shown, in some embodiments of the present invention, the horizontal limiting module 1 further includes a pushing component 13. The pushing component 13 includes a pushing block 131, a spring telescopic member, and a squeezing member 132. One end of the spring telescopic member is connected to the main body structure 11, and the other end of the spring telescopic member is connected to the pushing block 131. The pushing block 131 slides vertically to be suitable for driving the anti-blocking block 12 to extend along both sides of the main body structure 11. One end of the squeezing member 132 is connected to the pushing block 131. The main body structure 11 is provided with a squeezing pipe 15 communicating with the air inlet. The pushing block 131 slides downward in the vertical direction to drive the squeezing member 132 to extend into the squeezing pipe 15, so as to pressurize the cavity.

[0049] Specifically, the pushing component 13 is configured to provide power for the sliding of the anti-protection block 12. The elastic telescopic component 133 includes an elastic element and a telescopic column. The telescopic column can be pressed down in the vertical direction. The elastic element is sleeved on the telescopic column to provide an upward thrust for the telescopic column, thereby ensuring the reset of the telescopic column. One end of the elastic telescopic component 133 is fixedly connected to the main structure 11, and the other end is connected to the pushing block 131. The downward pressing of the telescopic column drives the pushing block 131 to move down, thereby pushing the two anti-protection blocks 12 to extend along both sides of the main structure 11.

[0050] It is understood that the air inlet is located on the concave side of the main structure 11, and the extrusion tube 15 is located on the concave side of the main structure 11. In some embodiments of the present invention, since there are two symmetrically distributed cavities and folded protective airbags 14, there are also two air inlets and extrusion tubes 15, which are correspondingly arranged in the cavities and folded protective airbags 14. Two extrusion members 132 are provided on the lower surface of the push block 131, wherein the two extrusion members 132 are cylinders, and the diameter of the extrusion members 132 is less than or equal to the inner diameter of the extrusion tube 15. When the push block 131 is pressed down, it drives the extrusion members 132 to be pressed down. The extrusion members 132 extend into the extrusion tube 15, thereby achieving pressurization and inflating the folded protective airbag 14.

[0051] In some embodiments of the present invention, the top of the main structure 11 is provided with a magnetic suction member, and the bottom of the push block 131 is magnetically attracted and connected to the magnetic suction member.

[0052] Specifically, the top of the main structure 11 is equipped with a magnetic attractor, specifically a magnet. The push block 131 is made of a magnetically attractable metal, specifically iron, nickel, or cobalt; in this invention, it is made of iron. Alternatively, the push block 131 can be made of plastic, with a magnetic component on its lower surface that has the opposite magnetic field to that of the magnetic attractor. This allows the bottom of the push block 131 to be magnetically attracted to the magnetic attractor, while the elastic telescopic component 133 provides an upward thrust, avoiding prolonged pressing and freeing up labor.

[0053] In some embodiments of the present invention, the clamping and limiting module 3 further includes a fixing rod 33, a screw 34 and a round shaft block 36. One end of the fixing rod 33 is fixedly connected to the spacing adjustment module 2, and the other end of the fixing rod 33 is provided with a threaded hole. The screw 34 passes through the threaded hole, and the round shaft block 36 is connected to the lower end of the screw 34. The first fixing block 31 and the second fixing block 32 are respectively rotatably connected to the two sides of the round shaft block 36.

[0054] Specifically, a threaded hole is opened at the other end of the fixing rod 33. One end of the fixing rod 33 is fixedly connected to the spacing adjustment module 2. The screw 34 passes through the threaded hole and is threadedly connected to the fixing rod 33. By turning the screw 34, the round shaft block 36 is driven to move in the vertical direction, thereby driving the first fixing block 31 and the second fixing block 32 to move in the vertical direction, so as to adjust the height of the tester's head, so that the camera module 4 is opposite to the tester's head, optimize the acquisition effect, and improve versatility.

[0055] It is understandable that both the first fixing block 31 and the second fixing block 32 are rotatably connected to the round shaft block 36. When the first fixing block 31 and the second fixing block 32 rotate towards each other, they clamp the person being tested. When the first fixing block 31 and the second fixing block 32 rotate away from each other, they release the person's head.

[0056] In some embodiments of the present invention, the first fixing block 31 and the second fixing block 32 are both arc-shaped, and the concave side of the first fixing block 31 and the concave side of the second fixing block 32 are arranged opposite to each other. The convex side of the first fixing block 31 and the convex side of the second fixing block 32 are provided with arc-shaped elastic limiting structures 35.

[0057] Specifically, both the first fixing block 31 and the second fixing block 32 are arc-shaped to accommodate the head of the person being tested, thus improving comfort. The arc-shaped elastic limiting structure 35 provides a reset function for the first fixing block 31 and the second fixing block 32, thereby improving the ease of operation.

[0058] Understandably, the first fixing block 31 and the second fixing block 32 are made of silicone or rubber, which are elastic and can improve comfort.

[0059] In some embodiments of the present invention, the spacing adjustment module 2 includes a first telescopic unit 21, a rotating joint 22, and a second telescopic unit 23. One end of the first telescopic unit 21 is hinged to the main structure 11, and the other end of the first telescopic unit 21 is connected to the rotating joint 22. One end of the second telescopic unit 23 is connected to the rotating joint 22, and the other end of the second telescopic unit 23 is connected to the other end of the fixing rod 33.

[0060] Reference Figure 5 As shown in the diagram, the spacing adjustment module 2 includes a first telescopic unit 21, a second telescopic unit 23, and a rotating joint 22 for connecting the first telescopic unit 21 and the second telescopic unit 23. The rotating joint 22 improves the flexibility of the spacing adjustment module 2. By adjusting the angle between the first telescopic unit 21 and the second telescopic unit 23 through the rotating joint 22, a large spacing adjustment can be achieved. By adjusting the telescopic extension and retraction of the first telescopic unit 21 and the second telescopic unit 23 themselves, a small spacing adjustment can be achieved, thereby improving the adjustment accuracy, optimizing the effect of facial information collection, and improving the efficiency of facial information collection.

[0061] In some embodiments of the present invention, the first telescopic unit 21 includes a first telescopic joint 211 and a second telescopic joint 212. One end of the first telescopic joint 211 is hinged to the main structure 11, and the other end of the first telescopic joint 211 is provided with a first limiting block. The second telescopic joint 212 is provided with a plurality of first limiting holes spaced apart along its length direction, which are suitable for engaging with the first limiting block. One end of the second telescopic joint 212 is sleeved on the first telescopic joint 211, and the other end of the second telescopic joint 212 is hinged to the rotating joint 22.

[0062] The second telescopic unit 23 includes a third telescopic section 231 and a fourth telescopic section 232. One end of the third telescopic section 231 is fixedly connected to the fixed rod 33, and the other end of the third telescopic section 231 is provided with a second limiting block. The fourth telescopic section 232 is provided with a plurality of second limiting holes spaced apart along its length direction, which are suitable for engaging with the second limiting block. One end of the fourth telescopic section 232 is sleeved on the third telescopic section 231, and the other end of the fourth telescopic section 232 is hinged to the rotating joint 22.

[0063] In some embodiments of the present invention, the face recognition device suitable for information collection further includes an information collection terminal 5 and a stabilizing rod 6. One end of the stabilizing rod 6 is connected to the information collection terminal 5, and the other end of the stabilizing rod 6 is connected to the main structure 11. The information collection terminal 5 is communicatively connected to the camera module 4. The information collection terminal 5 is suitable for collecting and processing the face information collected by the camera module 4.

[0064] Specifically, the information collection terminal 5 is connected to the main structure 11 via the stabilizer bar 6, achieving integrated setup and improving convenience.

[0065] In some embodiments of the present invention, an arc-shaped groove 111 is provided on the convex side of the main structure 11, and a slider 61 is provided in the arc-shaped groove 111. The other end of the stabilizing rod 6 is fixedly connected to the slider 61.

[0066] Specifically, an arc-shaped slide groove 111 is opened on the convex side of the main structure 11. The stabilizer 6 is connected to the slider 61 set in the arc-shaped slide groove 111. By sliding the slider 61 in the arc-shaped slide groove 111, the steering adjustment of the horizontal limit module 1 can be realized, thereby improving the applicability.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
