Description

Technical Field

[0001] This utility model relates to the field of facial recognition technology, and in particular to a three-camera facial recognition device for online examinations. Background Technology

[0002] Facial recognition technology is one of the most advanced and widely used technologies in the field of modern biometric identification. This technology captures and analyzes facial feature points and uses complex algorithms and machine learning models to achieve accurate identification of an individual. Its core principle is to collect facial images through camera equipment and extract unique biometric features, such as facial contours, eye distance, nose shape and other key feature parameters.

[0003] Existing facial recognition devices do not have the function of three-camera facial recognition. Because they can only capture facial images from a single angle, the recognition accuracy is limited, they cannot fully cover facial features, cannot effectively prevent cheating or impersonation, have many recognition loopholes, and are not very secure. Furthermore, existing devices cannot effectively adapt to various environmental conditions, such as indoor and outdoor environments and complex terrains, and cannot protect the stability of the device support.

[0022] Example 1

[0023] like Figure 1-5As shown, a three-position face recognition device for online examinations includes a base 1, a first threaded rod 2 and a second threaded rod 3. A first support plate 4 is fixedly connected to one side of the upper surface of the base 1, and a thread is provided on one side of the lower surface of the base 1. A dual motor 5 is fixedly connected to one side of the upper surface of the base 1, and a face recognition camera 6 is fixedly connected to the output end of the dual motor 5. There are two face recognition cameras 6.

[0024] In this embodiment, a fixing post 7 is fixedly connected to one side of the outer surface of the first support plate 4, a first support post 8 is threadedly connected to one side of the inner surface of the fixing post 7, a support shell 9 is fixedly connected to one side of the upper surface of the first support post 8, and an infrared camera 10 is rotatably connected to one side of the inner wall of the support shell 9. There are two infrared cameras 10.

[0025] In practical use, the device is fixed in position, the dual motors 5 are started, the face recognition camera 6 is set to its initial angle, and the infrared camera 10 is in standby mode, ready to be activated in low light conditions. The dual motors 5 are started to dynamically adjust their rotation to capture face images from different angles. The support shell 9 provides external protection for the infrared camera 10 and allows it to rotate to adjust its angle. When the device detects a face moving or adjusting its gaze, the dual motors 5 immediately adjust the angle of the infrared camera to continue tracking the face. The two infrared cameras 10 provide long-term, accurate monitoring in nighttime and low-light environments, achieving the effect of three-camera face recognition.

[0026] In this embodiment, the base 1 is threadedly connected to the first threaded rod 2, and a placement plate 11 is fixedly connected to one side of the lower surface of the first threaded rod 2.

[0027] In actual use, when placing the device on the desktop, the user needs to rotate the first threaded rod 2 to connect it with the base 1 in a threaded manner to fix the position of the placement plate 11 so that the device can be placed on the desktop.

[0028] In this embodiment, the second threaded rod 3 is threadedly connected to the base 1. A second support column 12 is fixedly connected to one side of the lower surface of the second threaded rod 3. A retainer 13 is fixedly connected to one side of the outer surface of the second support column 12. A protective sleeve 14 is snapped into one side of the inner wall of the retainer 13.

[0029] In actual use, the protective cover 14 is snapped into the housing 13, allowing the user to place the video recording device and achieve the purpose of placing the device in any situation.

[0030] In this embodiment, a fixed plate 15 is fixedly connected to the lower side of the second support column 12, a support frame 16 is fixedly connected to the lower surface of the fixed plate 15, a third support column 17 is fixedly connected to the lower surface of the fixed plate 15, and a limit member 18 is slidably connected to the outer surface of the third support column 17.

[0031] In practical use, the support frame 16 provides support, and the third support column 17 provides additional support through the sliding connection on its outer surface. The design of the limiting member 18 can effectively avoid structural instability or accidental damage caused by over-adjustment.

[0032] In this embodiment, a telescopic leg 19 is rotatably connected to one side of the outer surface of the support frame 16. There are three telescopic legs 19. A connecting rod 20 is rotatably connected to one side of the outer surface of the telescopic leg 19. The connecting rod 20 rotates with the limiting member 18.

[0033] In practical use, by rotating the telescopic leg 19, the connecting rod 20 rotates, which in turn drives the limiting member 18 to move downward, thereby limiting the telescopic leg 19.

[0034] In this embodiment, a protective shell 21 is fixedly connected to one side of the outer surface of the face recognition camera 6.

[0035] In practical use, the protective case 21 surrounds the face recognition camera 6 to provide it with robust physical protection.

[0036] Working Principle: In use, the device is fixed in position, the dual motors 5 are started, and the face recognition camera 6 is set to its initial angle. Simultaneously, the infrared camera 10 is in standby mode, ready to activate in low light conditions. The dual motors 5 dynamically adjust their rotation to capture facial images from different angles. The support shell 9 provides external protection for the infrared camera 10 and allows for its rotation to adjust its angle. When the device detects facial movement or a change in gaze, the dual motors 5 immediately adjust the camera angle to continue tracking the face. The two infrared cameras 10 provide accurate facial recognition in nighttime and low-light environments. For long-term, precise monitoring, when the user needs to place the device on a desktop, they can rotate the first threaded rod 2 to connect it to the base 1 in a threaded manner, fixing the position of the placement plate 11 so that the device can be placed on the desktop. When the height needs to be adjusted or the device needs to be placed on the ground, the user can pick up the second threaded rod 3, rotate the second threaded rod 3 to connect it to the base 1 in a threaded manner, rotate the telescopic leg 19, causing the connecting rod 20 to rotate, and at the same time driving the limiting member 18 to move downward, thus limiting the telescopic leg 19. The protective sleeve 14 is engaged with the locking case 13, allowing the user to place the video recording device, achieving the purpose of placing the device in any situation, and completing the use of the device.
