[0001] This invention belongs to the field of terminal camera system technology, specifically a face recognition device with a self-adjusting camera. Background Technology

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The self-adjusting camera face recognition device of the present invention is equipped with a light sensor and a light shield. On a sunny day, the light sensor collects the direction of sunlight in real time and converts it into an electrical signal, which is then transmitted to the controller. The controller drives the third motor to turn on, and the third motor drives the first gear to rotate. The first gear meshes with the gear ring, causing the gear ring to drive the light shield to rotate. The light shield reduces direct sunlight on the camera, which can effectively reduce the problem of image overexposure caused by excessive light. This makes the face image captured by the camera clearer and more detailed, thereby improving the accuracy and precision of face recognition.

[0020] 2. The self-adjusting camera face recognition device of the present invention, by means of a magnetic plate and a protrusion, when it rains, the light shield rotates to the bottom of the camera. At this time, the slide rod is pressed by the protrusion, causing the slide rod to slide inside the limiting plate. The slide rod drives the first conical block to move, causing the limiting rod to slide inside the first conical block, thereby driving the limiting rod to drive the moving block to slide. The moving block drives the baffle to slide and pushes the limiting block away from the first limiting groove, thereby releasing the limiting plate. At the same time, the slide rod drives the second gear to slide. The second gear moves to directly above the half gear. When someone stands in front of the display screen, the infrared sensor... When the device operates, it drives the fourth motor to open. The fourth motor drives the half gear to rotate, and the half gear meshes with the second gear, causing the slide rod to rotate. The slide rod drives the limit rod to rotate through the first limit groove, causing the limit rod to drive the limit plate to rotate through the moving block. The limit plate drives the light shield to reciprocate, allowing the light shield to clean rainwater from the mirror surface of the camera component. By automatically cleaning rain and snow, it can ensure that the camera always captures clear facial images, improving recognition speed and accuracy. It also prevents rain and snow from accumulating on the mirror surface of the camera component and forming a layer, which seriously affects the image clarity and reduces the efficiency of facial recognition.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 4 As shown in the figure, a face recognition device with a self-adjusting camera according to an embodiment of the present invention includes a display screen 1. A first fixing frame 2 is fixedly connected to the upper surface of the display screen 1. A second fixing frame 3 is rotatably connected to the upper surface of the first fixing frame 2. A housing 4 is rotatably connected inside the second fixing frame 3. A gear ring 43 is rotatably connected inside the housing 4. A light shield 44 is provided at one end of the gear ring 43. A camera component 8 is provided on the inner side of the gear ring 43. The camera component 8 is fixedly connected to the inner wall of the housing 4. A light sensor 41 is provided on one side of the gear ring 43. The light sensor 41 is fixedly connected to the inside of the housing 4.

[0038] like Figure 3 As shown, a first motor 21 is fixedly connected inside the first fixing frame 2, the output end of the first motor 21 is fixedly connected inside the second fixing frame 3, a second motor 31 is fixedly connected inside the second fixing frame 3, and the output end of the second motor 31 is fixedly connected to one side of the housing 4.

[0039] like Figure 4 As shown, a third motor 45 is provided at one end of the gear ring 43. The surface of the third motor 45 is fixedly connected to the inner wall of the housing 4. A first gear 46 is fixedly connected to the output end of the third motor 45. The first gear 46 and the gear ring 43 mesh with each other.

[0040] Specifically, existing facial recognition devices adjust the shooting height and shooting angle of the camera by installing axial and radial motors;

[0041] When existing facial recognition devices are installed outdoors for use, the angle of sunlight varies over time. When performing facial recognition operations, the camera may be exposed to direct sunlight, which may cause the captured image to be overexposed, making facial features blurry and affecting the recognition effect.

[0042] To solve the above problems, the working principle of this embodiment is as follows: The light sensor 41 in this device is existing technology. Its specific operation is as follows: When used outdoors on a sunny day, the light sensor 41 collects the direction of sunlight in real time and converts it into an electrical signal. Then, the electrical signal is transmitted to the controller. The controller controls the third motor 45 to turn on. The third motor 45 drives the first gear 46 to rotate. The first gear 46 meshes with the gear ring 43, so that the gear ring 43 drives the light shield 44 to rotate. The light shield 44 blocks the sunlight. At the same time, the user can point the camera at their face for face recognition. Then, the user can observe the face recognition data on the display screen 1.

[0043] When axial rotation is required, the first motor 21 can be turned on. The first motor 21 drives the second fixed frame 3 to rotate, the second fixed frame 3 drives the housing 4 inside it to rotate, and the housing 4 drives the camera component 8 to rotate axially, which can be used for face recognition from different shooting angles.

[0044] When radial rotation is required, the second motor 31 can be turned on. The second motor 31 drives the housing 4 to rotate, and the housing 4 can drive the camera component 8 to rotate radially, so that the appropriate shooting height can be adjusted to perform face recognition.

[0045] This embodiment avoids direct sunlight on the camera, which effectively reduces image overexposure caused by excessive light, making the facial images captured by the camera clearer and more detailed, thereby improving the accuracy and precision of facial recognition.

[0046] Example 2

[0047] like Figure 3 As shown in the first embodiment, another embodiment of the present invention is as follows: an infrared sensor 42 is provided on one side of the light sensor 41, the infrared sensor 42 is fixedly connected to the inner wall of the housing 4, and one side of the light shield 44 and one end of the camera are located on the same horizontal plane.

[0048] like Figure 4 and Figure 5 As shown, a limiting plate 5 is fixedly connected to the rotating end of the light-shielding plate 44. A first spring 51 is fixedly connected between the limiting plate 5 and one end of the gear ring 43. A first limiting groove 510 is symmetrically opened on the surface of the limiting plate 5. A limiting block 52 is slidably connected inside the first limiting groove 510. The surface of the limiting block 52 is slidably connected to one end of the gear ring 43. A second spring 53 is fixedly connected between the limiting block 52 and one end of the gear ring 43.

[0049] like Figures 7 to 9As shown, a movable block 54 is provided on one side of the limiting block 52. The movable block 54 is slidably connected to the inner wall of the first limiting groove 510. A baffle 55 is symmetrically slidably connected to one end of the movable block 54. One side of each baffle 55 is in contact with the inner wall of the first limiting groove 510. A third spring 56 is fixedly connected between two baffles 55. A sliding rod 58 is slidably connected inside the limiting plate 5. A first conical block 582 is fixedly connected to one end of the sliding rod 58. A second limiting groove 583 is symmetrically provided on the surface of the first conical block 582. A limiting rod 57 is slidably connected inside each of the second limiting grooves 583. One end of each limiting rod 57 is fixedly connected to one end of the movable block 54.

[0050] like Figure 4 and Figure 5 As shown, a second gear 581 is fixedly connected to the surface of the slide rod 58, a fourth motor 7 is provided on one side of the second gear 581, the fourth motor 7 is fixedly connected to the inner lower surface of the housing 4, and a half gear 71 is fixedly connected to the output end of the fourth motor 7. The half gear 71 and the second gear 581 mesh with each other.

[0051] Specifically, in rainy or snowy weather, the light intensity is low. If the light shield 44 continues to block the light from the camera component 8, it may further reduce the amount of light entering the camera lens, resulting in a dark monitoring image that affects the image clarity and detail capture capability. In addition, in rainy or snowy weather, rainwater and snow may fall on the surface of the camera component 8, accumulating to form a water film or water droplets, which seriously affects the image clarity and thus reduces the efficiency of face recognition.

[0052] To solve the above problems, the working principle of this embodiment is as follows: The infrared sensor 42 in this device is existing technology, and its specific operation is as follows: In rainy or snowy weather, the gear ring 43 drives the light-shielding plate 44 to rotate to the bottom side of the camera assembly 8, preventing the light-shielding plate 44 from continuing to block the light of the camera assembly 8. When the gear ring 43 rotates, it drives the limiting plate 5 to rotate, and the limiting plate 5 drives the slide rod 58 inside it to rotate. One end of the slide rod 58 slides on the surface of the magnetic plate 6. When the light-shielding plate 44 moves to directly below the camera assembly 8, the slide rod 58 moves to the surface of the protrusion 61. At this time, the slide rod 58 is squeezed by the protrusion 61, causing the slide rod 58 to slide towards the inner wall of the limiting plate 5 and squeeze the fifth spring 585. The slide rod 58 drives the first conical block 582 and the first gear 46 on its surface to slide synchronously. When the first gear 46 moves to directly above the half gear 71, the first bevel gear slides, driving the limiting rod 57 to slide in the second limiting groove 583 inside, causing the limiting rod 57 to be squeezed. The limiting rod 57 drives the moving block 54 to slide to the outside of the first limiting groove 510. While the moving block 54 slides, it pushes the limiting block 52 to move synchronously, causing the limiting block 52 to squeeze the second spring 53 and disengage from the inside of the first limiting groove 510. At the same time, the moving block 54 drives the baffle 55 to slide synchronously inside the first limiting groove 510. Under the action of the third spring 56, the baffle 55 fills the gap between the first limiting groove 510, preventing the limiting block 52 from resetting into the gap between the first limiting groove 510 and the moving block 54, thus preventing the limiting plate 5 from rotating.

[0053] Subsequently, when the user stands in front of the display screen 1, the infrared sensor 42 detects the infrared radiation emitted by the human body and generates an electrical signal, which is then transmitted to the controller. The controller drives the fourth motor 7 to work, and the fourth motor 7 drives the half gear 71 to rotate. The half gear 71 rotates and meshes with the second gear 581. The second gear 581 rotates and drives the slide rod 58 to rotate. The slide rod 58 drives the lower limit plate 5 to rotate through the limit rod 57 in the second limit groove 583. The limit plate 5 drives the light shield 44 to rotate. The light shield 44 cleans the rain and snow on the surface of the camera component 8. Then the camera component 8 can clearly perform face recognition. When the half gear 71 does not mesh with the second gear 581, the first spring 51 drives the limit plate 5 to reset, and the limit plate 5 drives the light shield 44 to reset.

[0054] This second embodiment can automatically clean the rain and snow on the surface of the camera component 8, ensuring that the camera always captures clear facial images, improving recognition speed and accuracy, and preventing rain and snow from accumulating on the mirror surface of the camera component 8 and forming a layer that seriously affects the clarity of the image, thereby reducing the efficiency of facial recognition.

[0055] like Figure 6As shown, a fifth spring 585 is fixedly connected between the surface of the slide rod 58 and the inner wall of the limiting plate 5. A magnetic plate 6 is provided on one side of the slide rod 58. The magnetic plate 6 is fixedly connected to the inner wall of the housing 4. A protrusion 61 is fixedly connected to one side of the magnetic plate 6. Both the protrusion 61 and one side of the magnetic plate 6 are slidably connected to one end of the slide rod 58.

[0056] like Figure 12 As shown, a magnetic rod 59 is slidably connected to the inner wall of the slide rod 58, the protrusion 61 is supported by magnetic material, the magnetism of the magnetic rod 59 and the magnetism of the first magnetic plate 6 attract each other, the magnetism of the magnetic rod 59 and the magnetism of the protrusion 61 repel each other, and a sixth spring 592 is fixedly connected between the surface of the magnetic rod 59 and the inner wall of the slide rod 58.

[0057] like Figures 10 to 12 As shown, a second conical block 591 is fixedly connected to one end of the magnetic rod 59. The inner wall of the second conical block 591 matches the inner wall of the slide rod 58. Limiting holes 584 are provided inside the second limiting groove 583. A limiting ball 572 is slidably connected inside the limiting rod 57. The size of the limiting ball 572 matches the size of the limiting hole 584. A fourth spring 571 is fixedly connected between one side of the limiting ball 572 and the inner wall of the limiting rod 57.

[0058] Specifically, when the aforementioned slider 58 slides due to external factors, the movement of the slider 58 may release the limiting plate 5, causing the limiting plate 5 to cause the light shield 44 to be released from its fixed position and rotate on sunny days. This may fail to reduce the direct sunlight on the camera, resulting in a blurry face image.

[0059] To solve the above problem, when one end of the slide rod 58 and one end of the protrusion 61 are in contact, the magnetism of the protrusion 61 and the magnetic rod 59 repels each other, causing the magnetic rod 59 to slide inside the slide rod 58 and compress the sixth spring 592. The sliding of the magnetic rod 59 drives the second conical block 591 to slide, and the second conical block 591 compresses the limiting ball 572. The limiting ball 572 slides from the limiting hole 584 and compresses the fourth spring 571 and is housed inside the limiting rod 57, thereby releasing the restriction between the slide rod 58 and the limiting rod 57. Subsequently... The slide rod 58 is pressed by the protrusion 61, causing the limiting rod 57 to drive the limiting ball 572 to slide in the second limiting groove 583. When one end of the slide rod 58 is in contact with one side of the magnetic plate 6, the magnetic rod 59 inside the slide rod 58 and the magnetic plate 6 attract each other. The magnetic rod 59 and the slide rod 58 are reset and reset by the fourth spring 571, so that the limiting ball 572 enters the limiting hole 584. The limiting ball 572 can realize the limiting between the limiting plate 5 and the slide rod 58, avoiding the problem of the slide rod 58 moving due to external factors.

[0060] Working principle: The light sensor 41 in this device is existing technology. Its specific operation is as follows: When used outdoors on a sunny day, the light sensor 41 collects the direction of sunlight in real time and converts it into an electrical signal. Then, the electrical signal is transmitted to the controller. The controller controls the third motor 45 to turn on. The third motor 45 drives the first gear 46 to rotate. The first gear 46 meshes with the gear ring 43, causing the gear ring 43 to drive the light shield 44 to rotate. The light shield 44 blocks the sunlight. At the same time, the user can point the camera at their face for face recognition. Then, the user can observe the face recognition data on the display screen 1.

[0061] When axial rotation is required, the first motor 21 can be turned on. The first motor 21 drives the second fixed frame 3 to rotate, the second fixed frame 3 drives the housing 4 inside it to rotate, and the housing 4 drives the camera component 8 to rotate axially, which can be used for face recognition from different shooting angles.

[0062] When radial rotation is required, the second motor 31 can be turned on. The second motor 31 drives the housing 4 to rotate, and the housing 4 can drive the camera component 8 to rotate radially, so that the appropriate shooting height can be adjusted to perform face recognition.

[0063] In rainy or snowy weather, the gear ring 43 drives the light shield 44 to rotate to the bottom of the camera assembly 8, preventing the light shield 44 from continuing to block the light from the camera assembly 8. When the gear ring 43 rotates, it drives the limiting plate 5 to rotate, and the limiting plate 5 drives the slide rod 58 inside it to rotate. One end of the slide rod 58 slides on the surface of the magnetic plate 6. When the light shield 44 moves directly below the camera assembly 8, the slide rod 58 moves to the surface of the protrusion 61. At this time, the slide rod 58 is squeezed by the protrusion 61, causing the slide rod 58 to slide towards the inner wall of the limiting plate 5 and squeeze the fifth spring 585. The slide rod 58 drives the first conical block 582 and the first gear 46 on its surface to slide synchronously. The first gear 46 moves directly above the half gear 71. When sliding, the driving limit rod 57 slides in the second limit groove 583 inside, causing the limit rod 57 to be squeezed. The limit rod 57 drives the moving block 54 to slide to the outside of the first limit groove 510. While the moving block 54 slides, it pushes the limit block 52 to move synchronously, causing the limit block 52 to squeeze the second spring 53 and disengage from the inside of the first limit groove 510. At the same time, the moving block 54 drives the baffle 55 to slide synchronously inside the first limit groove 510. Under the action of the third spring 56, the baffle 55 fills the gap between the first limit groove 510, preventing the limit block 52 from resetting into the gap between the first limit groove 510 and the moving block 54, thus preventing the limit plate 5 from rotating.

[0064] Subsequently, when the user stands in front of the display screen 1, the infrared sensor 42 detects the infrared radiation emitted by the human body and generates an electrical signal, which is then transmitted to the controller. The controller drives the fourth motor 7 to work, and the fourth motor 7 drives the half gear 71 to rotate. The half gear 71 rotates and meshes with the second gear 581. The second gear 581 rotates and drives the slide rod 58 to rotate. The slide rod 58 drives the lower limit plate 5 to rotate through the limit rod 57 in the second limit groove 583. The limit plate 5 drives the light shield 44 to rotate. The light shield 44 cleans the rain and snow on the surface of the camera component 8. Then the camera component 8 can clearly perform face recognition. When the half gear 71 does not mesh with the second gear 581, the first spring 51 drives the limit plate 5 to reset. The limit plate 5 drives the light shield 44 to reset for subsequent cleaning operations.

[0065] When one end of the slide rod 58 and one end of the protrusion 61 are in contact, the magnetism of the protrusion 61 and the magnetic rod 59 repels each other, causing the magnetic rod 59 to slide inside the slide rod 58 and compress the sixth spring 592. The sliding of the magnetic rod 59 drives the second conical block 591 to slide, and the second conical block 591 compresses the limiting ball 572. The limiting ball 572 slides from the limiting hole 584 and compresses the fourth spring 571 and is housed inside the limiting rod 57, thereby releasing the connection between the slide rod 58 and the limiting rod 57. The limit is set between 7, and then the slide bar 58 is squeezed by the protrusion 61, causing the limit bar 57 to drive the limit ball 572 to slide in the second limit groove 583. When one end of the slide bar 58 is in contact with one side of the magnetic plate 6, the magnetic rod 59 inside the slide bar 58 and the magnetic plate 6 attract each other, the magnetic rod 59 and the slide bar 58 reset, and are reset by the fourth spring 571, so that the limit ball 572 enters the limit hole 584, and the limit operation between the limit plate 5 and the slide bar 58 can be performed.
