The principles and structures of the present utility model are described in detail below with reference to the drawings and the examples.
As an embodiment, referring to fig. 1-6, the present utility model proposes an automatic zooming face recognition module structure, which includes a PCB board 10, a first automatic zooming module 20 and a second automatic zooming module 30; a first automatic zooming module 20 and a second automatic zooming module 30 are arranged on one side of the PCB board 10.
The first automatic zooming module 20 is configured to automatically zoom and collect face image information in a normal light environment.
The second automatic zooming module 30 is used for automatically zooming and collecting face image information in a dark environment.
Specifically, the imaging lenses of the first automatic zoom module 20 and the second automatic zoom module 30 can perform automatic zooming according to the distance between the imaging lenses and the face to be recognized (the distance is 20cm-120 cm), so that even if the recognition distance is not within the recognition distance of the fixed focus imaging lens (the recognition distance of the fixed focus imaging lens is generally 40cm-100 cm), the first automatic zoom module 20 and the second automatic zoom module 30 can perform automatic zooming, the distance between the imaging lenses of the first automatic zoom module 20 and the second automatic zoom module 30 and the face to be recognized is still within the recognition distance (20 cm-120 cm), the first automatic zoom module 20 and the second automatic zoom module 30 can still acquire clear face image information, and the face image information acquired by the first automatic zoom module 20 and the second automatic zoom module 30 is prevented from losing details, so that the situation of blurring is caused. And the first automatic zooming module 20 and the second automatic zooming module 30 can ensure that the automatic zooming face recognition module structure can work all day.
Specifically, referring to fig. 3-4, the first automatic zoom module 20 includes a first photosensitive chip 201, a first bracket 202, a first optical filter 203, a first voice coil motor 204, and a first imaging lens 205; the first filter 203 and the first imaging lens 205 are preferably circular, and the diameter of the first filter 203 is larger than the diameter of the first imaging lens 205.
The PCB 10 is provided with a first photosensitive chip 201, the PCB 10 is provided with a hollow first bracket 202 corresponding to the first photosensitive chip 201, and one side of the first bracket 202 facing the first photosensitive chip 201 is provided with a first optical filter 203.
A first voice coil motor 204 is arranged on the other side of the first bracket 202, which is away from the first photosensitive chip 201, a first camera lens 205 is connected in the first voice coil motor 204, and the light incident side of the first camera lens 205 is away from the first optical filter 203; the first bracket 202 is used for fixing the first voice coil motor 204, so as to prevent the first camera lens 205 on the first voice coil motor 204 from being misplaced with the first photosensitive chip 201.
And the first voice coil motor 204 can drive the first camera lens 205 to perform linear and limited swing angle movements.
When the first automatic zooming module 20 needs zooming, the first voice coil motor 204 drives the first camera lens 205 to perform linear and limited swing angle movements, so that the distance between the first camera lens 205 and the face to be recognized is kept within the recognition distance as much as possible, the face recognition precision is improved, and the first photosensitive chip 201 can acquire clear face image information.
The first automatic zooming module 20 is used for automatically zooming and collecting face image information in a normal light environment. Therefore, the first image capturing lens 205 is an RGB image capturing lens, and RGB in the RGB image capturing lens is a color mode, and represents three colors of red (R), green (G), and blue (B), respectively, which is the most widely used color mode.
The first filter 203 allows light to pass through the wavelength band of 380nm-760nm, and the light wavelength band of 380nm-760nm is visible light.
Therefore, when the identified face passes through the first imaging lens 205 to generate an optical image, the optical image is projected onto the surface of the first photosensitive chip 201, and during the projection process, the first optical filter 203 filters out the light wave band outside 380nm-760 nm.
Specifically, referring to fig. 3 and fig. 5, the second automatic zoom modules 30 each include a second photosensitive chip 301, a second bracket 302, a second optical filter 303, a second voice coil motor 304, and a second imaging lens 305; the second filter 303 and the second imaging lens 305 are preferably circular, and the diameter of the second filter 303 is larger than the diameter of the second imaging lens 305.
The PCB 10 is provided with a second photosensitive chip 301, the PCB 10 is provided with a hollow second bracket 302 corresponding to the second photosensitive chip 301, and one side of the second bracket 302 facing the second photosensitive chip 301 is provided with a second optical filter 303.
A second voice coil motor 304 is arranged on the other side of the second bracket 302, which is away from the second photosensitive chip 301, a second camera lens 305 is connected in the second voice coil motor 304, and the light incident side of the second camera lens 305 is away from the second optical filter 303; the second bracket 302 is used for fixing the second voice coil motor 304, so as to prevent the second imaging lens 305 on the second voice coil motor 304 from being misplaced with the second photosensitive chip 301.
And the second voice coil motor 304 can drive the second camera lens 305 to perform linear and limited swing angle movements.
When the second automatic zooming module 30 needs zooming, the second voice coil motor 304 drives the second camera lens 305 to perform linear and limited swing angle movements, so that the distance between the second camera lens 305 and the face to be recognized is kept within the recognition distance as much as possible, the face recognition precision is improved, and the second photosensitive chip 301 can acquire clear face image information.
The second automatic zooming module 30 is used for automatically zooming and collecting face image information in a dark environment. Therefore, the second image capturing lens 305 is an infrared image capturing lens, i.e. an IR lens, which uses a special optical glass material, and uses the latest optical design method to eliminate the focal plane shift of the visible light and the infrared light, so that the light rays from the visible light to the infrared light region can be imaged on the same focal plane, and the images can be clear. In addition, the IR lens also adopts a special multilayer coating technology to increase the transmittance of infrared rays, so that the infrared imaging lens is more suitable for being used in a dark environment.

The light-compensating lamp 40 is an infrared LED lamp, and the light-compensating lamp 40 is located between the first and second auto-zoom modules 20 and 30.
The light supplement lamp 40 is associated with the positional relationship between the first and second auto zoom modules 20 and 30 and the field angle FOV of the first and second auto zoom modules 20 and 30 themselves. When the field angle FOV of the second automatic zoom module 30 is larger, the emission field range of the light filling lamp 40 needs to be selected to be large, so that the field angle FOV of the second automatic zoom module 30 is conveniently covered; the light supplementing lamp 40 can be closer to the second automatic zooming module 30, so that the emitting visual field range of the light supplementing lamp 40 can better cover the visual field angle FOV of the second automatic zooming module 30, and the second automatic zooming module 30 can acquire clearer face image information.
In order to improve the aesthetic property of the automatic zooming face recognition module structure, referring to fig. 1 in this embodiment, a shielding bracket 50 is further disposed on the PCB board 10, and the shielding bracket 50 shields the first automatic zooming module 20, the second automatic zooming module 30 and the light supplementing lamp 40.

In this embodiment, referring to fig. 1, the PCB board 10 is further provided with a processing unit 60, a driving unit 70, and a storage unit 80.

The driving unit 70 is used for controlling the first voice coil motor 204 or the second voice coil motor 304 to drive the corresponding first imaging lens 205 or second imaging lens 305 to perform linear and limited-swing-angle motion, so that the corresponding first imaging lens 205 or second imaging lens 305 performs auto-zoom.
As an embodiment, an intelligent face recognition door lock includes the automatic zooming face recognition module structure described in any one of the above.
The intelligent face recognition door lock further comprises a rechargeable battery, a key, a light sensor, a door lock assembly and the like which are applied to the existing intelligent face recognition door lock.
The first automatic zooming module 20 and the second automatic zooming module 30 in the automatic zooming face recognition module structure can automatically zoom, so that the distance between the first camera lens 205 and the second camera lens 305 and the face to be recognized can be kept between 20cm and 120cm, and further, the first automatic zooming module 20 and the second automatic zooming module 30 can acquire clear face image information at a long distance and a short distance, and the success rate of successful unlocking of the intelligent face recognition door lock can be improved.
The intelligent face recognition door lock disclosed by the utility model has the following application principle:
When the face to be recognized is in the normal light environment, the first automatic zooming module 20 automatically zooms (i.e. the processing unit 60 controls the driving unit 70 to control the first voice coil motor 204 to drive the first camera lens 205 to perform linear and limited swing angle movements) when the face to be recognized is in front of the first automatic zooming module 20, so that the face to be recognized is kept within the recognition distance of the first automatic zooming module 20 as much as possible, the recognition precision of the face to be recognized is improved, the first photosensitive chip 201 can acquire clear face image information and upload the clear face image information to the processing unit 60, the processing unit 60 compares the received face image information with the face image information stored in the storage unit 80 in advance, and the intelligent face recognition door lock is successfully unlocked after the comparison is successful.
When the face to be recognized is in the dark environment, the second automatic zooming module 30 automatically zooms (i.e. the processing unit 60 controls the driving unit 70 to control the second voice coil motor 304 to drive the second camera lens 305 to perform linear and limited swing angle movements) when the face to be recognized is in front of the second automatic zooming module 30, so that the face to be recognized is kept within the recognition distance of the second automatic zooming module 30 as much as possible, the recognition precision of the face to be recognized is improved, the second photosensitive chip 301 can acquire clear face image information and upload the clear face image information to the processing unit 60, the processing unit 60 compares the received face image information with the face image information stored in the storage unit 80 in advance, and the intelligent face recognition door lock is successfully unlocked after the comparison is successful.
Principle of automatic zooming by the first automatic zooming module 20 and the second automatic zooming module 30:
First, when the identified face is at the identification distance of the first automatic zoom module 20 or the second automatic zoom module 30, the driving unit 70 will first control the first voice coil motor 204 or the second voice coil motor 304 to drive the corresponding first camera lens 205 or the second camera lens 305 to move from the original position to the maximum displacement, at this time, the imaging surface of the corresponding first photosensitive chip 201 or the second photosensitive chip 301 will automatically collect the face image information and upload the face image information to the processing unit 60, and the processing unit 60 calculates the MTF value corresponding to each displacement point and forms the MTF graph (refer to fig. 6) through the uploaded face image information. Wherein MTF is modulation transfer function, which means modulation degree along with the change of space frequency; the sharpness of the face image information collected by the first photosensitive chip 201 or the second photosensitive chip 301 can be indicated by the MTF value, and the greater the MTF value, the higher the sharpness.
The maximum MTF value is found in the MTF graph, and the current corresponding to the point is obtained through a specific algorithm, and then the processing unit 60 controls the instruction driving unit 70 to provide the current to the corresponding first voice coil motor 204 or second voice coil motor 304 again, so that the corresponding first imaging lens 205 or second imaging lens 305 moves to the displacement corresponding to the current, and automatic zooming is achieved. At this time, the face image information collected by the imaging surface of the first photosensitive chip 201 or the second photosensitive chip 301 is the clearest.
The driving unit 70 provides a current to the internal coil of the first voice coil motor 204 or the second voice coil motor 304, and the coil generates a magnetic force according to the current, so as to drive the corresponding first imaging lens 205 or second imaging lens 305 to displace, thereby forming an auto-focusing effect. The displacement distances of the first imaging lens 205 or the second imaging lens 305 are different for different magnitudes of currents.
The current magnitude calculated by the MTF value belongs to the existing calculation mode, and will not be described herein.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
