Detailed Description
In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those skilled in the art that the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. It should be noted that, in the present invention, the same reference numbers and names in the respective drawings denote the same elements.
Fig. 1 shows according to the utility model discloses a face identification entrance guard's structural schematic diagram, as shown in the figure, face identification entrance guard includes entrance guard main part 100, reflect arrangement 200 and adjusting device 300, and reflect arrangement 200 can reflect out user's facial image, and adjusting device 300 is used for adjusting reflect arrangement 200 for when reflect arrangement 200 reflects out user's complete facial image, user's whole facial also is located entrance guard main part 100's identification range.
Fig. 2 shows a schematic structural diagram of the door lock main body according to the present invention, and as shown in the figure, the door lock main body 100 includes a housing 110, a control main board 120, a control chip 130, and a camera device; the housing 110 has an accommodating cavity 111, the control main board 120 is disposed in the accommodating cavity 111, and the control chip 130 is disposed on the control main board 120; an image pickup device is disposed on the front surface of the housing 110, and the image pickup device may be electrically connected to the control chip 130 through the control motherboard 120. The control chip 130 processes the facial image of the user captured by the camera device, and controls the electric lock electrically connected with the face recognition access control to be in an open state or a closed state according to the processing result. The image of the face of the user is captured by a camera device, which may comprise one or more cameras, and fig. 2 shows a case where the camera device comprises two cameras 141 and 142. One of the cameras 141 and 142 may be a visible light camera for face recognition, and the other of the cameras 141 and 142 may be an infrared camera for face live detection. When the camera device includes an infrared camera, the door access main body 100 may further include an infrared light supplement lamp 150 disposed on the front surface of the casing 110 and electrically connected to the control main board 120, for providing an infrared illumination environment required by the infrared camera.
