Embodiment 1

[0047] Such as Figure 1-3 As shown, the self-depth optimized face recognition device according to the embodiment of the present invention includes a housing 1 and a standing board 2 located at the bottom of the housing 1 , and a side of the housing 1 close to the standing board 2 is opened. There is a chute 3, a slide block 4 matching it is provided in the chute 3, a first motor 5 is provided at the bottom end in the housing 1, and the output end of the first motor 5 is provided with an extension to In the chute 3 and through the screw rod 6 of the slider 4, the slider 4 is provided with a three-dimensional face recognition mechanism 7, and one side of the housing 1 is provided with the three-dimensional face recognition mechanism 7. A distance sensor 8 matched by the mechanism 7, and a height positioning mechanism 11 is fixed on the slider 4 above the three-dimensional face recognition mechanism 7;

[0048] The three-dimensional face recognition mechanism 7 includes an arc-...

Embodiment 2

[0051] Such as figure 1 As shown, the top of the stand plate 2 is provided with a second pressure sensor 9, and the second pressure sensor 9, the distance sensor 8, the three-dimensional face recognition mechanism 7 and the first motor 5 are respectively connected with The controller 10 located on one side of the housing 1 is electrically connected. Both the first motor 5 and the second motor 22 are multi-frequency explosion-proof forward and reverse motors.

Embodiment 3

[0053] Such as Figure 4-5 As shown, the height positioning mechanism 11 includes a connecting seat 25, a pressing plate 26 is arranged on the connecting seat 25, a number of supplementary lights 27 are fixed under the pressing plate 26, and the pressing plate 26 is far away from the connection One end of the seat 25 is fixedly provided with a third pressure sensor 28, the periphery of the third pressure sensor 28 is located at the lower end of the pressing plate 26 and is connected with a top plate 30 through several springs 29, and a sponge pad 31 is arranged under the top plate 30, The periphery of the sponge pad 31 is connected with the pressing plate through a sealing cloth.

[0054] Through the above-mentioned technical scheme, the reflective rate of the face can be increased by the supplementary light 27, and then the collected data can be made more real and accurate. By setting the third pressure sensor 28, when the pressing plate 26 moves down to a certain extent, the...

Abstract

The invention discloses a self-depth optimization face recognition device and a method thereof. The device comprises a shell and a standing plate located at the bottom end of the shell. A sliding groove is formed in the side, close to the standing plate, of the shell. A sliding block matched with the sliding groove is arranged in the sliding groove. A first motor is arranged at the bottom end in the shell, a lead screw extending into the sliding groove and penetrating through the sliding block is arranged at the output end of the first motor, a three-dimensional face recognition mechanism is arranged in the sliding block, and a distance sensor matched with the three-dimensional face recognition mechanism is arranged on one side of the shell. The beneficial effects are that the motor drivesthe screw rod to rotate to lift the three-dimensional face recognition mechanism to a proper height, so that the three-dimensional face recognition mechanism is suitable for people of different heights; the internal face recognition reference library can be dynamically updated based on a self-depth optimization algorithm according to a time period and a feature data change rate. Therefore, the face recognition rate of people whose faces are in a rapid growth and development or aging stage is greatly improved, and the application range and depth of the face recognition technology in differentpeople and different fields are greatly improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a self-depth optimized face recognition device and method thereof. Background technique [0002] Face recognition technology is an important technology in image processing, and it is an active research field in biometric recognition. It uses computer vision and image processing technology to perform face recognition by using the contour features and local detail features of the face. At present, it has been applied in identity authentication and authority control. [0003] However, the low recognition rate is an important reason that has hindered the wide application of face recognition technology, especially the existing technology is aimed at children and adolescents in the rapid growth and development stage, and the recognition success rate of the elderly in the rapid aging stage is insufficient. [0004] Aiming at the problems in the related technologies, no effect...
