In order to solve the above problem, an embodiment of the present application provides a recognition apparatus, which can improve recognition accuracy of the recognition apparatus.

For ease of understanding, the structure of the identification means will be described below.

Referring to fig. 1, an identification apparatus 100 according to an embodiment of the present disclosure includes a processor 110, a 3D information generator 120, and a dual-pass camera 130.

The processor 110 is connected to the 3D information generator 120 and the dual-pass camera 130, respectively. The following description will be made with respect to the processor 110, the 3D information generator 120, and the dual-pass camera 130, respectively.

The dual-pass camera 130 includes a filter, and a dual-pass filter is disposed on the filter and used for filtering light rays in other bands except for a visible light band and an infrared light band, and enabling the light rays in the visible light band and the infrared light band to enter the camera. Therefore, the dual-pass camera 130 has the capability of imaging visible light and infrared light, an image obtained by shooting the object to be recognized may include an RGB image portion and an infrared image portion at the same time, and accordingly, the image information obtained by the dual-pass camera 130 includes RGB image information and infrared image information. Under the condition that the infrared light is weak, the infrared image part obtained by shooting by the double-pass camera 130 is weakened, and at the moment, the image obtained by the double-pass camera 130 is mainly an RGB image; in the case of weak visible light, the RGB image portion captured by the dual-pass camera 130 is weakened, and at this time, the image captured by the dual-pass camera 130 is mainly an infrared image.

In an alternative embodiment, the infrared light that can be used for imaging by the dual-pass camera 130 is near-infrared light, such as near-infrared light having a processing wavelength of 850nm or near-infrared light having a wavelength of 940 nm. Accordingly, in this case, the dual band pass filter is used to filter out light in the visible light band and other bands except the near infrared light band.

The 3D information generator 120 is used to provide 3D information for image information captured by the dual-pass camera 130.

In an alternative embodiment, the 3D information generator 120 may be a structured light assembly. The light source of the structured light module is a VCSEL (Vertical Cavity Emitting Laser), which is referred to as a Surface Emitting Laser for short, and is one of the light sources used for optical fiber communication. The light source of the structured light assembly can be irradiated on the object to be recognized, the bi-pass camera 130 takes a picture of the object to be recognized, and 3D information corresponding to the object to be recognized is carried in image information of an image shot by the bi-pass camera 130, so that the follow-up face recognition is facilitated, and the performance of the living body detection is improved.

In another alternative embodiment, the 3D information generator 120 may be a projector 121. Referring to fig. 2, the projector 121 may include a light source 122 and a housing 123.

Wherein, in some embodiments, the light source 122 may be an LED light source. The LED light source 122 is more cost effective than a VCSEL light source, and thus, the cost of manufacturing the projector 121 is lower than the cost of manufacturing the structured light assembly. The LED light source 122 will be described later by way of example.

The cover 123 covers the LED light source 122, and a plurality of light-transmitting regions 124 are disposed on the cover 123.

The projector 121 mainly plays a role of providing 3D information and as a supplementary lighting device.

When the LED light source 122 emits light, the light passes through the light-transmitting regions 124 and is emitted, so that the emitted light takes the shape of a plurality of light-transmitting regions 124. At this time, if the light rays showing the shapes of the plurality of light transmission regions irradiate the object to be recognized, and the bi-pass camera 130 takes a picture of the object to be recognized, the image information of the image taken by the bi-pass camera 130 carries the 3D information corresponding to the object to be recognized, so that the performance of the living body detection is improved when the face recognition is performed subsequently.

In an alternative embodiment, the shape of the light-transmitting area 124 may be a stripe shape with alternate light and dark as shown in fig. 2, and the transmittance of the light and dark stripes to the light emitted from the LED light source 122 is different, and at this time, the light emitted from the projector 121 also appears as a light spot in a stripe shape as shown in fig. 3. Of course, the contrast of the bright and dark fringes should be controlled within a certain threshold range, for example, in some embodiments, the contrast should be not less than 50%.

Of course, in other embodiments, the shape of the light-transmitting region 124 may be other shapes, such as a circle, a triangle, etc., and is not limited herein.

The above-mentioned, the light that the projecting apparatus 121 dispersed out can shine on waiting to discern the object, at this moment, if wait to discern the object and be in the environment that light is darker, because all signals (including visible light and infrared light) that the light that the environment provided carried are all relatively weak, the light that the projecting apparatus 121 dispersed out can also play the effect of light filling, make more light can enter into in the bi-pass camera 130, thereby guarantee the image quality of the image that the bi-pass camera 130 shot, so that improve follow-up face identification's precision.

Further, in an alternative embodiment, when the projector 121 is employed as the 3D information generator 120, the wavelength band of light emitted from the LED light source 122 of the projector 121 is adapted to the wavelength band of infrared light that can be processed by the dual pass camera 130. Generally, the light emitted by the LED light source 122 is mainly near infrared light of 850nm or 940nm, and correspondingly, the infrared light that can be used for imaging by the dual-pass camera 130 is near infrared light with a wavelength of 850nm or 940 nm. For example, in one embodiment, the wavelength band of the light emitted by the LED light source 122 is substantially 940nm, and then the infrared light processed by the dual-pass camera 130 is near infrared light with a wavelength of 940nm for adaptation. At this time, if the object to be recognized is located in an environment with darker light, the light emitted by the projector 121 is also mainly near-infrared light, which is equivalent to that the projector 121 is used as a near-infrared light supplement device of the dual-pass camera 130, so that more infrared light can enter the dual-pass camera 130, thereby ensuring the image quality of the infrared image captured by the dual-pass camera 130, and improving the accuracy of subsequent living body detection and face recognition.

The processor 110 has data processing capability and can receive information transmitted by the 3D information generator 120 and the dual-pass camera 130, thereby implementing functions of living body detection and face recognition.

The effect to be achieved by the living body detection is to judge whether the object to be identified is a living body; the effect to be achieved by face recognition is to determine whether the object to be recognized is a target.

The target object can represent one person or multiple persons, and needs to be set according to actual conditions. For example, when the recognition apparatus 100 is applied to an intelligent door lock, face images of a plurality of persons having unlocking authority may be stored in the intelligent door lock as target objects (the target objects at this time represent a plurality of persons); when the recognition apparatus 100 is applied to the handset unlock, a face image of the handset owner may be stored in the handset as a target object (the target object at this time represents a person).

In general, prior to face recognition, live body detection is performed.

When the detection result of the living body detection indicates that the object to be recognized is not a living body, the processor 110 directly outputs the recognition result indicating that the recognition is not passed, terminates the current recognition, and does not perform the subsequent face recognition process any longer, thereby preventing the recognition device 100 from outputting the recognition passed result when someone takes a still image (e.g., a photograph) of the target object to the recognition device 100 for recognition.

When the recognition result of the living body detection represents that the object to be recognized is the living body, the processor 110 further determines whether the object to be recognized is the target object, and outputs the recognition result according to the determination result, wherein when the object to be recognized is the target object, the output recognition result is used for representing that the recognition is passed, and when the object to be recognized is not the target object, the output recognition result is used for representing that the recognition is not passed.

The following will describe a process in which the recognition apparatus 100 operates.

In the embodiment of the present application, the identification appliance 100 initiates the first operating state in a low-light environment.

When the recognition apparatus 100 is in the first operation state, the processor 110 transmits a start signal to the 3D information generator 120 and the dual-pass camera 130.

The 3D information generator 120 and the dual-pass camera 130 are turned on after receiving the start signal, and transmit the acquired image information with the 3D information of the object to be recognized to the processor 110 for recognition. Since the image information at this time carries 3D information, the single bi-pass camera 130 can also ensure the performance of the living body detection and the face recognition.

Furthermore, it is worth pointing out that the infrared light provided by other light sources in the same wavelength band as that generated by the 3D information generator 120 interferes with the effect of the 3D information generator 120. For example, when the 3D information generator 120 is the projector 121, the disturbance is embodied in causing the shape of the light-transmitting area in the image captured by the two-way camera 130 to fade or disappear, thereby disturbing the effect of the projector 121.

However, in a dark environment, since the light information provided by the natural light itself is weak, the infrared light carried in the natural light is less, and the effect of the projector 121 is not disturbed. Even if the fluorescent lamp or the incandescent lamp (generally referred to as an indoor environment) is turned on, the infrared light generated by the fluorescent lamp or the incandescent lamp is limited, and generally only a small amount of light energy in the wavelength band of the near infrared light is contained, and the effect of the projector 121 is not interfered. Therefore, the 3D information generator 120 can be used in a dark situation, and is not affected by fluorescent lamps or incandescent lamps in most indoor environment scenes.

As for the situation that the 3D information generator 120 is inevitably affected when the light is in a relatively sufficient outdoor environment (the near infrared light in the sunlight becomes light or disappears, which may also cause a problem of structural light failure), in this case, the 3D information generator 120 may cause the infrared biopsy performance to be degraded, which may cause the attack missing rate to be greatly increased, and cause a safety problem), at this time, in order to improve the biopsy performance and the face recognition accuracy of the recognition apparatus 100, please refer to fig. 4, in another embodiment, the recognition apparatus 100 may further include a visible light camera 140, and the visible light camera 140 is connected to the processor 110.

The visible light camera 140 is configured to image visible light and shoot an object to be recognized to obtain an RGB image. In this embodiment, the identification appliance 100 initiates the second operating state in a well-lit environment.

When the recognition device 100 is in the second working state, the processor 110 transmits a start signal to the visible light camera 140 and the double-pass camera 130. Of course, since the 3D information generator 120 is interfered by a large amount at this time, the effect is not large, and the processor 110 may transmit a shutdown signal to the 3D information generator 120 at this time for the principle of saving power consumption.

After each component acquires a control signal (an opening signal or a closing signal), corresponding action is executed. At this time, it is assumed that the 3D information generator 120 is turned off and the visible light camera 140 and the dual-pass camera 130 are turned on.

Under the assumption, the visible light camera 140 obtains the image information of the RGB image with the object to be recognized, and the dual-pass camera 130 obtains the image information of the RGB image with the object to be recognized (since the wavelength band of infrared light is small in an environment with sufficient light, the image information obtained by the dual-pass camera 130 at this time is mainly an RGB image).

At this time, the visible light camera 140 and the dual-pass camera 130 transmit image information of the RGB images respectively acquired to the processor 110, and the processor 110 calculates to obtain 3D information corresponding to the object to be recognized according to the RGB images provided by the visible light camera 140 and the RGB images provided by the dual-pass camera 130. Subsequently, the processor 110 performs live detection on the object to be recognized according to the 3D information corresponding to the object to be recognized, and performs face recognition based on the image information of the RGB image after the live detection passes. Therefore, the performance of living body detection and the accuracy of face recognition can be ensured.

It should be noted that the process of the processor 110 performing the living body detection and the process of performing the face recognition by combining the 3D information and the image information, and the process of the processor 110 calculating the 3D information corresponding to the object according to the two RGB images of the same object are mature prior art, and are not described herein again.

It is further worth noting that the identification device 100 may not comprise means for detecting the ambient brightness level when the identification device 100 only has the first operating state.

When the recognition device 100 has the first operating state and the second operating state, as can be seen from the above description, in order to enable the recognition device 100 to have better living body detection and face recognition performance under different environments, the first operating state needs to be started in an environment with dark visible light, and the second operating state needs to be started in an environment with sufficient visible light, in which case, the recognition device 100 further includes a component for detecting the brightness of the environment.

In an alternative embodiment, a detection component for detecting the ambient brightness, such as a visible light illumination intensity sensor, may be additionally added to the identification apparatus 100. Accordingly, the detection component detects the intensity of the visible light in the environment and transmits the intensity to the processor 110. 110 determines that the current light intensity is lower than the threshold, and controls the identification device 100 to be in the first working state, and when the processor 110 determines that the current light intensity is greater than or equal to the threshold, controls the identification device 100 to be in the second working state.

In another alternative embodiment, the visible light camera 140 may also be directly used as a detection component for detecting the ambient light level. At this time, the visible light camera 140 may be always in an on state or in an on state for a fixed period of time set by the recognition apparatus 100, and transfer the photographed image to the processor 110. The processor 110 analyzes the brightness of the image, and controls the recognition device 100 to be in the first working state when the brightness of the image is lower than the threshold value, and controls the recognition device 100 to be in the second working state when the brightness is greater than or equal to the threshold value.

Through the arrangement, the recognition device 100 can provide good living body detection performance and human face detection accuracy under the application scenes with sufficient light and the application scenes with insufficient light, and therefore the recognition accuracy of the recognition device 100 in 24 hours all day can be improved.

In addition, an electronic device is further provided in an embodiment of the present application, and the electronic device may include a display screen and the identification apparatus 100 provided in any of the above embodiments.

The display screen has a locked state and an unlocked state. When the display screen of the electronic device is in a locked state, the user can perform face recognition based on the recognition apparatus 100. After the electronic equipment acquires the identification result, whether the display screen is switched from the locking state to the unlocking state can be determined according to the identification result. For example, when the identification result is characterized as successful identification, the display screen is switched from the locking state to the unlocking state, otherwise, the locking state is continuously maintained.

In addition, this application embodiment still provides an intelligent lock, and intelligent lock includes identification means 100 and the spring bolt that any above-mentioned embodiment provided.

The lock tongue is provided with an opening state and a locking state. The identification device 100 may control the lock tongue according to its own identification result, for example, when the identification result indicates that the identification is successful, the lock tongue is controlled to be in an open state, otherwise, the lock tongue is controlled to be in a locked state.

In addition, this application embodiment still provides an intelligence door, including above-mentioned intelligence lock and door plant, intelligence lock sets up on the door plant.

In summary, the embodiment of the present application provides an identification device, in the identification device, a processor, a 3D information generator and a dual-pass camera for processing visible light and infrared light are provided. The 3D information generator is used for providing 3D information for image information which is shot by the bi-pass camera and corresponds to an object to be recognized, so that the processor can acquire the image information comprising the 3D information, and therefore the performance of in-vivo detection is improved when in follow-up in-vivo detection and face recognition are facilitated, and the accuracy of face recognition is improved.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
