DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, in order to improve the quality and efficiency of face forgery identification, this embodiment provides a face forgery identification device, which can achieve more efficient and accurate identification of whether a face is forged by more comprehensive feature extraction of the face.

[0023] See also Figures 1 to 5 This embodiment proposes a face forgery identification device, including a base 1, a bracket 2 and an identification device body 3, and the identification device body 3 is rotatably mounted on the top of the base 1 through the bracket 2.

[0024] The internal core part of the identification device body 3 is mainly composed of a branch feature extractor, a positioning and classification module, and is equipped with an intelligent processor for wireless signal transmission and reception, which facilitates automatic and comprehensive multi-angle feature extraction of the face.

[0025] The branch feature extractor module is able to extract a feature map of a specific resolution generated by each branch. This feature map helps the branch to perform fine-grained classification at the corresponding level. For example, for the finest level (i.e., identifying a single forgery method), it is necessary to model the content of all spatial locations, which requires a high-resolution feature map. In contrast, for the coarsest level (i.e., binary) classification, the lowest resolution feature map will be used, and different forgery methods will produce different manipulated areas.

[0026] The goal of the localization module is to map the feature output of the highest resolution branch to a mask to locate the forged area. The entire process embodies the characteristics of the self-attention mechanism, which emphasizes important features and suppresses unimportant features by evaluating the relationship between each pixel and all other pixels, thereby generating an accurate tampering localization mask.

[0027] The classification module can force the establishment of dependencies between attribute classifications at different levels, so that each branch considers the output of higher-level branches when calculating its probability. This hierarchical structure and method help to more finely analyze and locate forged content, thereby improving the accuracy and efficiency of face forgery detection.

[0028] The bracket 2 is fixedly connected to the upper surface of the base 1, and the rotating shafts on both sides of the identification device body 3 are respectively installed in the reserved holes on both sides of the bracket 2. By describing the relationship between the identification device body 3 and the bracket 2, the identification device body 3 can be stably rotated on the bracket 2, which is convenient for adjusting the inclination angle of the device, which is beneficial to the multi-angle and all-round recognition and identification of the face.

[0029] An angle adjustment mechanism 4 is provided on the outside of the identification equipment body 3, and the angle adjustment mechanism 4 includes a worm gear 401 fixedly connected to the end of the rotating shaft of the identification equipment body 3, and a worm 402 and a first servo motor 403 are installed on the outer surface of the bracket 2. The output shaft end of the first servo motor 403 is fixedly connected to the rotating shaft end of the worm 402, the worm gear 401 is meshed with the worm 402, and the first servo motor 403 is electrically connected to the electrical components inside the identification equipment body 3.

[0030] When it is necessary to extract facial features through the identification device body 3, the first servo motor 403 can be controlled by the identification device body 3. When the first servo motor 403 is started, the worm 402 will be driven to rotate, and the rotation of the worm 402 will cause the worm wheel 401 to rotate. The combination of the worm 402 and the worm wheel 401 has the effect of deceleration and self-locking. Therefore, the identification device body 3 can be limited after adjusting the tilt angle, which is convenient for the stable extraction of facial features from different angles, and is beneficial to the subsequent facial forgery identification work.

[0031] A direction adjustment mechanism 5 is provided below the base 1 , and the direction adjustment mechanism 5 includes a connecting column 501 and an installation box 502 . The top of the connecting column 501 is fixedly connected to the bottom surface of the base 1 , and the connecting column 501 is rotatably sleeved on the inner top wall of the installation box 502 .

[0032] By setting the connecting column 501 and the installation box 502, the identification device body 3 can be rotated in the inner wall of the installation box 502 through the connecting column 501, which is convenient for adjusting the horizontal direction of the identification device body 3 and is beneficial to the comprehensive extraction of facial features.

[0033] The bottom end of the connecting column 501 extends to the interior of the installation box 502 and is fixedly connected to a first planar gear 503. The inner top wall of the installation box 502 is fixedly connected to a second servo motor 504. The output shaft of the second servo motor 504 is fixedly connected to a second planar gear 505 meshing with the first planar gear 503. The second servo motor 504 is electrically connected to the electrical components inside the identification equipment body 3.

[0034] By setting the first planar gear 503, the second servo motor 504 and the second planar gear 505, when the second servo motor 504 is driven to work, the connecting column 501 can be driven to rotate through the first planar gear 503 and the second planar gear 505, so that the identification device body 3 can be rotated in a horizontal position through the base 1, which is convenient for automatically adjusting the orientation of the identification device body 3, which is beneficial to more comprehensive feature extraction of the human face and makes the result of counterfeit identification more accurate.

[0035] A plurality of auxiliary rods 507 are rotatably connected to the upper surface of the connecting column 501 , and a circular track 506 is fixedly connected to the bottom surface of the base 1 . Each auxiliary rod 507 is rotatably sleeved in the inner wall of the circular track 506 .

[0036] The annular track 506 and the auxiliary rod 507 can make the base 1 more stable when rotating, so that the device can be used to extract features of the face more stably, which is beneficial to the subsequent identification of whether the face is forged.

[0037] A disassembly and assembly mechanism 6 is provided towards the interior of the adjustment mechanism 5, and the disassembly and assembly mechanism 6 includes a bidirectional threaded rod 602 rotatably sleeved on the inner wall of the installation box 502, and two slide grooves 603 are provided on the bottom surface of the installation box 502, and a positioning plate 601 is slidably sleeved on the inner wall of each slide groove 603, and the outer surface of the bidirectional threaded rod 602 is threadedly connected to two connecting plates 604, and the two connecting plates 604 are respectively fixedly connected to the upper surfaces of the two positioning plates 601.

[0038] When the bidirectional threaded rod 602 is rotated, the two positioning plates 601 can be moved toward or away from each other through the two connecting plates 604, so that the device can be quickly positioned at a suitable position through the two positioning plates 601, thereby improving the convenience of using the device. The device can also be quickly disassembled, which facilitates the reuse of the device in different locations.

[0039] Two limit rods 605 are fixedly connected to the inner wall of the installation box 502, and the two sides of the two connecting plates 604 are slidably mounted on the outer surfaces of the two limit rods 605. The two ends of the bidirectional threaded rod 602 pass through the two sides of the installation box 502 and are fixedly connected to handles 606.

[0040] By providing the limit rod 605, the two connecting plates 604 can be made more stable when moving, and by providing the handle 606, the friction force can be increased, so that the staff can more easily rotate the bidirectional threaded rod 602, which is beneficial to the installation and positioning work of the device.

[0041] Working principle: When in use, the device can be positioned and installed in a suitable position through the two positioning plates 601 at the bottom of the device. At this time, the movement of the two positioning plates 601 can be controlled by rotating the handle 606. When the handle 606 is rotated, the two-way threaded rod 602 will rotate. When the two-way threaded rod 602 rotates, the two connecting plates 604 will move closer to or away from each other along the two limit rods 605. In this way, the two positioning plates 601 can move closer to or away from each other, so that the device can be clamped and fixed in a suitable position. Then, the identification device body 3 can be used to identify facial forgery. When the identification device body 3 is turned on, the facial features can be collected from multiple angles. The wireless signal transceiver intelligent processor inside the identification device body 3 can control the operation of the first servo motor 403 and the second servo motor 504. When the first servo motor 403 is working When the second servo motor 504 is working, it can drive the second planar gear 505 to rotate. By setting the first planar gear 503 meshing with the second planar gear 505, the connecting column 501 can be rotated. When the connecting column 501 rotates, the base 1 can be rotated, thereby achieving the effect of changing the horizontal direction of the identification device body 3. In this way, by adjusting the inclination angle and horizontal direction of the identification device body 3, the branch feature extractor module of the identification device body 3 can extract all-round and multi-angle features of the face, and through the positioning and classification module inside the identification device body 3, the extracted features can be more finely analyzed and the counterfeit content can be located, thereby effectively improving the accuracy and efficiency of the device in detecting face counterfeiting, and being more practical.
