In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure.

The face recognition is a biological feature recognition technology for identity authentication based on human physiognomic feature information, and the maximum feature of the face recognition technology is that personal information can be prevented from being leaked and the face recognition technology is used for recognition in a non-contact mode. Face recognition and fingerprint recognition, palm print recognition, retina recognition, skeleton recognition, heartbeat recognition and the like belong to human body biological feature recognition technologies, and are generated along with the rapid development of technologies such as a photoelectric technology, a microcomputer technology, an image processing technology, pattern recognition and the like. However, the face recognition device in the prior art can only recognize two-dimensional information of a face, which results in low recognition accuracy. Therefore, the embodiment of the application provides a sensor module.
Referring to fig. 1, fig. 1 shows a schematic structural diagram of a sensor module 10 provided in an embodiment of the present application. The sensor module 10 includes a frame 16 and a plurality of electronics disposed within the frame 16. Wherein the frame 16 serves as a support structure for supporting a plurality of electronic devices.
The plurality of electronic devices include at least a projector 12, a first camera 15, and a second camera 14. The projector 12, the first camera 15, and the second camera 14 are disposed in the frame 16 and arranged in a single row along the length direction of the frame 16.
The projector 12 is used to project light for identifying stereoscopic information of the object to the object. Illustratively, the projector 12 is a 3D structured light projector, and the 3D structured light projector emits millions of projected light rays onto the recognition object, and the light rays form different light spots when being irradiated on different parts of the human face. As an alternative, the projector 12 provided in the embodiment of the present application employs an infrared light projector that can emit infrared light to illuminate the target object. Illustratively, the infrared light projector may be an infrared laser. It should be understood that the projector 12 provided in the embodiments of the present application may use other wavelengths of light besides infrared light, and is not particularly limited in the embodiments of the present application.
The first camera 15 is used for shooting light spots formed by the light projected to the target object by the projector 12. Illustratively, the first camera 15 may receive reflections of the light spots emitted by the projector 12 and take 2D infrared images. In the embodiment of the present application, the first camera 15 is an infrared camera. The infrared camera adopts optical glass to eliminate the focal plane offset of visible light and infrared light, so that light rays from the visible light to the infrared light area can be imaged on the same focal plane, and images can be clear. In addition, the infrared camera also adopts a multilayer light-transmitting film to increase the transmittance of infrared rays.
The second camera 14 is used to capture a two-dimensional image of the object. Illustratively, the second camera 14 is an RGB camera for capturing a color image of the subject. Wherein R, G, B represents three colors of red, green and blue.
As an optional scheme, the sensor module 10 further includes a floodlight 13, and the floodlight 13 is disposed in the frame 16 and is used for illuminating the target object to improve the brightness of the target object, so as to improve the face recognition effect. Exemplarily, the floodlight 13 is an infrared floodlight, which can emit infrared light for supplementing infrared light to the target object to improve the shooting effect of the first camera 15.
It will be appreciated that in use of the sensor module 10, both the projector 12 and the floodlight 13 emit infrared light, in order to avoid the object being too close to the sensor module, which could cause the emitted infrared laser light to harm the human eye. The sensor module 10 provided by the embodiment of the present application further includes a distance sensor 11 disposed in the frame 16, where the distance sensor 11 is used for detecting a distance from an object to the sensor module 10. When the sensor module 10 is applied to a face recognition module, when a main board of the face recognition module receives that the distance from the target object detected by the distance sensor 11 is too short, the alarm can be controlled to give an alarm to remind the target object. It should be understood that the alarm of the main board according to the detected distance is a conventional alarm measure, and the circuit connection relationship between the main board, the distance sensor 11 and the alarm will not be described in detail herein.
With continued reference to fig. 2, when the projector 12, the first camera 15, the second camera 14, the floodlight 13 and the distance sensor 11 are disposed within the frame 16, the projector 12, the first camera 15, the second camera 14, the floodlight 13 and the distance sensor 11 are arranged in a single row. Wherein the floodlight 13 is positioned in the middle of the frame 16; the first camera 15 and the second camera 14 are positioned at one side of the floodlight 13; the distance sensor 11 and the projector 12 are located on the other side of the floodlight 13. When the above structure is adopted, the floodlight 13 is located at the middle position of the frame 16, and when the floodlight is used for light compensation, the light can be more uniformly irradiated to the target object. The projector 12 is close to the floodlight 13 so that the irradiated light can be uniformly irradiated to the target object. And the distance sensor 11 is positioned at the outermost end, so that the detection distance can be ensured, and the influence of the arranged distance sensor 11 on the work of other functional devices can be avoided.
As can be seen from the above description, the sensor module 10 according to the embodiment of the present invention can acquire images representing different characteristics of the target object, such as RGB images, IR images, and depth images of the target object, by matching the projector 12 with the first camera 15, and input 3 images into the biopsy model, so as to obtain a biopsy result and improve the accuracy of biopsy. In addition, when carrying out face payment, through the cooperation of projecting apparatus 12, first camera 15, second camera 14, can carry out intelligent acquisition to face information automatically, extract face facial characteristics, can carry out the collection of different angles to the static face, the developments face of people's face to reach identification's purpose and accomplish light payment, improve face identification's the degree of accuracy.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a face recognition module 100 according to an embodiment of the present disclosure. The face recognition module 100 provided in the embodiment of the present application is composed of a plurality of stacked layer structures. Illustratively, the face recognition module 100 includes a first bracket 20, a main board 30, and a sensor module 10, which are stacked. The first bracket 20 is located in the middle, and the main board 30 and the sensor module 10 are respectively arranged on two sides of the first bracket 20, so as to form a sandwich structure.
For convenience of understanding, first, the relationship between the three is described, and the first bracket 20 serves as a supporting structure of the entire face recognition module 100 and is used for fixing the sensor module 10 and the main board 30; the sensor module 10 is used for adopting the image of the target object, and the main board 30 is used for processing the image collected by the sensor module 10 to obtain the face information of the target object. It should be understood that the main board 30 obtains the face information according to the image acquisition of the target object, which is common information processing in the prior art, and is specifically implemented by a processor or a circuit, and is not specifically limited in the embodiment of the present application.
Referring also to fig. 3, fig. 3 is an exploded view of the face recognition module 100.
The first bracket 20 serves as a supporting structure of the whole face recognition module 100, and the first bracket 20 is a plate-shaped structure having two opposite surfaces, and the two surfaces respectively serve as assembling surfaces. In assembly, the sensor module 10 is fixed to one surface of the first bracket 20, and the main board 30 is fixed to the other surface of the first bracket 20.
It should be understood that the first bracket 20 provided in the embodiments of the present application may be made of a metal material or a non-metal material, and only needs to have a certain supporting strength. For example, the first bracket 20 may be made of different materials such as aluminum, stainless steel, plastic, resin, etc.
The main board 30 is used as a data processing component of the face recognition module 100, and a circuit capable of processing an image acquired by the sensor module 10 is disposed thereon, and a specific circuit on the main board 30 is not specifically limited in this embodiment, and a conventional circuit for processing image data in the prior art may be used, and therefore details are not repeated in this embodiment.
When the main board 30 is connected to the first bracket 20, the main board 30 is detachably and fixedly connected to the first bracket 20. Specifically, different connection modes such as threaded connection, clamping connection and the like can be adopted.
For example, the first bracket 20 and the main plate 30 may be connected by a first threaded connector 70, and the first bracket 20 is provided with a threaded hole corresponding to the first threaded connector 70. During assembly, the first threaded connector 70 is threaded through the main plate 30 and then screwed into the threaded hole, thereby fixing the main plate 30 to the first bracket 20.
It should be understood that although fig. 3 illustrates that the main plate 30 is locked on the first bracket 20 by two first threaded connectors 70 arranged diagonally, the number of the first threaded connectors 70 is not particularly limited in the embodiment of the present application, and the first threaded connectors 70 may be different in number of two, three, four, etc., as long as the main plate 30 can be fixed on the first bracket 20.
As an alternative, when the main board 30 is fixedly connected to the first bracket 20, a space for accommodating electronic devices on the main board 30 is formed between the first bracket 20 and the main board 30. That is, when the motherboard 30 is assembled, the side on which the electronic device is disposed faces the first bracket 20, and when the motherboard 30 and the first bracket 20 are fixed, the electronic device can be accommodated in the gap between the first bracket 20 and the motherboard 30. At this time, the first bracket 20 may be regarded as a protective case of the electronic device, thereby improving the safety of the electronic device.
When the sensor module 10 is assembled with the first bracket 20, the sensor module 10 is detachably and fixedly connected with the first bracket 20. Specifically, the sensor module 10 and the first bracket 20 may be connected by different connection methods, such as a snap connection or a threaded connection.
The first bracket 20 and the sensor module 10 are connected by a screw connection. The face recognition module 100 further includes a second bracket 50, and the second bracket 50 serves as a support structure for the sensor module 10. When assembled, the frame of the sensor module 10 is secured to the second bracket 50. Illustratively, the frame of the sensor module 10 is fixed to the second bracket 50 by means of bonding.
The second bracket 50 is stacked with the first bracket 20, and the second bracket 50 is located on a side of the first bracket 20 facing away from the main board 30. When assembled, the second bracket 50 is removably and fixedly attached to the first bracket 20. Illustratively, the second bracket 50 is connected with the first bracket 20 through a second threaded connector 80, and the first bracket 20 is provided with a threaded hole corresponding to the second threaded connector 80. The second screw connector 80 is screwed into the screw hole after passing through the second bracket 50, thereby fixing the second bracket 50 to the first bracket 20.
