General overview:
the invention relates to an identity card reader for a hotel, which is mainly used for the identity and face information co-comparison verification of hotel guests, and transmits information to a public security system, so that the accuracy of face identification information is improved, a user with poor eyesight can be assisted to calibrate and conveniently and quickly de-align an identification frame, and the user with normal eyesight can calibrate and acquire information more quickly, and compared with the traditional face information acquisition mode, the face information reader is more accurate, and a reference object is used for guiding a face direct-view lens instead of a direct-view display screen 1, thereby being beneficial to better screening face information. The above process is realized by the following structure:
as shown in figure 1 of the drawings, the main structure comprises an identity card reader, a display screen 1 and a base 2, wherein the identity card reader is arranged in the base 2, when the identity card reader communicates with an identity card, the identity card reader sends out a group of electromagnetic waves with fixed frequency to the identity card, and a series resonance circuit is arranged in the card, the frequency of the series resonance circuit is the same as the frequency emitted by the card reader, so that the resonance circuit generates resonance under the excitation of the electromagnetic waves, and charges are arranged in a capacitor. The other end of the charge is connected with a one-way conduction electronic pump, the charge in the capacitor is sent to another capacitor for storage, and when the accumulated charge reaches 2V, the capacitor can be used as a power supply to provide working voltage for other circuits, and data in the card is transmitted or received by the data of the identity card reader.
The base 2 cooperation is equipped with display screen 1, and display screen 1 mainly shows camera 3 shooting information in real time, and the auxiliary user of being convenient for shows the position of adjusting self and camera 3 according to display screen 1, be equipped with facial information acquisition module and auxiliary calibration module in the display screen 1, following for specific structure:
face information acquisition module:
as shown in fig. 1 of the drawings in the specification, the facial information acquisition module comprises a camera 3 and a sensor 4; the sensor 4 is arranged in the display screen 1, the sensor 4 is a distance sensor 4, and the distance sensor 4 generally refers to all sensors 4 capable of measuring distance, and specifically refers to: a sensor 4 for measuring distance using the time of flight principle; a sensor 4 that can generate a signal for a change in distance. For detecting the distance between the face and the camera 3. The distance sensor 4 may calculate the distance to the object by emitting a beam of energy and reflecting it off the object to be measured, and calculating the time the beam is emitted until it is reflected off the object. The sensor 4 cooperates with controlling photographing of the camera 3 and rotation of the following rotation mechanism according to the detected position information of the human face, and the following is a specific structure of the auxiliary calibration module:
an auxiliary calibration module:
as shown in fig. 4 of the drawings, the auxiliary calibration module comprises an auxiliary light source and a rotating mechanism; the auxiliary light source is connected with a rotating mechanism, and the rotating mechanism can drive the auxiliary light source to rotate to change the angle of the auxiliary light source; the auxiliary light source is arranged in the rear shell 5 of the display screen 1, the auxiliary light source is a micro laser head 6, the micro laser head 6 is formed by combining a laser diode and a lens, the laser diode can generate a scattered sheet light source after being electrified, and the lens combined with the laser diode intensively emits the scattered light source of the laser diode to present a laser beam, namely a point light source. The micro laser head 6 is selected because the display screen 1 is free and narrow in the rear shell 5 and the size of the laser head and the size of the light source are not greatly influenced.
Since the heights of each person are different, in order to reduce the excessive difference in height, which leads to the excessive following swing amplitude of the micro laser head 6, the following specific structure when the lenses are the convex lens 7 and the concave lens 8 is further improved:
convex lens 7:
the cooperation of miniature laser head 6 is equipped with the lens, the lens sets up on back casing 5 surface, the lens is convex lens 7, and miniature laser head 6 is coaxial with the main optical axis of convex lens 7, and the convex lens 7 can be with miniature laser head 6 penetrating light source after refracting according to the refraction principle of convex lens 7 to the wall 16, can roughly divide into three types according to customer's height, overlook, head-up, look up and go to observe camera 3, so specific light path diagram is as shown in figure 5 of the specification, according to the principle of convex lens 7 refraction: when the object distance (the micro laser head 6) is larger than 1 time and smaller than 2 times of focal length, the micro laser head emits an inverted and amplified real image to the convex lens 7, the distance is larger than the object distance, the represented real image is larger than the object image, and the object image and the real image are on opposite sides.
Therefore, the position of the real image can be changed by changing the angle of the micro laser head 6, as shown in fig. 4 of the specification, in order to observe the image and the calibration frame of the display screen 1, the display screen 1 and the base 2 are in an acute angle, but the auxiliary light source in the device is parallel to the base 2, so the angle of the camera 3 has little influence on the projection angle, because the camera 3 has a capturing range and has errors influenced by the vision, the capturing result of the face recognition is not influenced greatly by the excessively high precision of the auxiliary light source, the angle difference between the display screen 1 and the micro laser head 6 can be ignored, the height of the customer can be roughly divided into three types by the height detected by the distance sensor 4, and the angles of the face and the camera 3 only need to be distinguished according to the three conditions so as to adjust the angle of the light source emitted by the micro laser head 6.
As shown in fig. 5 a of the drawings, the camera 3 is seen in a plan view: since the light source emitted from the micro laser head 6 needs to be refracted to the lower side of the convex lens 7 through the convex lens 7, the micro laser head 6 needs to be emitted to the upper side of the convex lens 7 through the driving angle adjustment of the rotating mechanism, which is described below, and since the object image and the real image are on opposite sides, that is, the laser direction emitted from the micro laser head 6 is opposite to the emitting direction through the convex lens 7, the real image which is presented after being refracted through the concave lens 8 is located below the convex lens 7. When the camera 3 is observed in the upward view shown in the point C: since the light source emitted by the micro laser head 6 is required to be refracted to the upper part of the convex lens 7 through the convex lens 7, the micro laser head 6 is required to be emitted to the lower part of the convex lens 7 through the driving angle adjustment of the micro speed reducing motor 12, and the object image and the real image are on opposite sides, so the real image which is refracted by the concave lens 8 is positioned above the convex lens 7; when the head-up observation camera 3 shown in the point B: the micro laser head 6 emits light through the optical center of the convex lens 7 and emits light along the optical center of the convex lens 7. The auxiliary light source in the rear shell 5 of the display screen 1 is refracted to the outside through the refraction principle of the convex lens 7, and is projected on the wall behind the device after being amplified, and the direction of the face and the camera 3 is changed through observing the position of the light source.
Because the laser emitted by the micro laser head 6 is refracted by the convex lens 7 and then presents an inverted and amplified real image, the amplified laser point appears on the wall or the ground, and in order to be further suitable for the accurate guidance of a visual user, the surface of the micro laser head 6 is provided with a guide head, the guide head is provided with a guide sheet, and the guide sheet is provided with a guide frame; the guide piece is a plastic piece, the plastic piece is similar to a film bottom piece, a guide frame pattern is arranged on the plastic piece, and the guide frame part is transparent. According to the principle of projection, laser light is emitted from the transparent portion of the plastic sheet when emitted, thereby projecting an enlarged guide frame pattern on the wall. The user who can see clearly is convenient for carry out face information acquisition according to the guide of guide frame pattern, also can make the user who has poor eyesight see the guide frame according to the approximate scope of guide frame and carry out face information acquisition, and multiple condition can all adapt to. The principle and method of concave lens 8 are as follows:
concave lens 8:
the lens is arranged on the surface of the rear shell 5, the lens is a concave lens 8, a specific light path diagram of the concave lens 8 is shown in figure 6 of the specification, and the lens is based on the principle of refraction of the concave lens 8: when the object is a virtual object, the object distance (the micro laser head 6) is larger than 1 time and smaller than 2 times of focal length, and the object distance is shot to the concave lens 8, an inverted and enlarged virtual image is displayed, and the image and the object are arranged on the opposite side of the lens; when the object is a virtual object, it is for the combined device that after the previous lens (or mirror) is imaged, if the position of this image is behind the secondary lens, the object is virtual for the secondary lens (or mirror). Since the above-described micro laser head 6 is refracted by a lens as laser light, the laser light refracted by the lens is a virtual object for the concave lens 8. The concave lens 8 has a divergent function to light, and the laser emitted by the micro laser head 6 diverges outwards when refracted by the lens, and the light propagation direction passing through the optical center is not changed, so that compared with the refraction of the convex lens 7, the rotation angle of the rotation mechanism required by the concave lens 8 is smaller.
It should be noted that the concave lens 8 presents an inverted and enlarged virtual image, which cannot be reached by the actual light, and thus cannot be received by the light screen or the wall surface 16 for display, and the virtual image cannot be observed by naked eyes, and can only be observed through the optical element glass or the like. It is said that a glass plate 15 needs to be added behind the concave lens 8 to be able to present a virtual image refracted by the concave lens 8. In order to avoid the unclear virtual image, the concave lens 8 cannot be added with a guide head and other components to serve as a guide visual client.
As shown in fig. 6 of the drawings, when the camera 3 is seen in a plan view, indicated by a point D: since the light source emitted from the micro laser head 6 needs to be refracted to the lower side of the concave lens 8 through the concave lens 8, the micro laser head 6 needs to be emitted to the lower side of the concave lens 8 through the driving angle adjustment of the rotating mechanism, which is described below, and since the object image and the real image are on opposite sides, that is, the laser direction emitted from the micro laser head 6 is opposite to the emitting direction through the concave lens 8, the real image which is presented after being refracted through the concave lens 8 is located below the concave lens 8. When the camera 3 is observed in the F point looking up mode: the light source emitted by the micro laser head 6 needs to be refracted to the upper part of the concave lens 8 through the concave lens 8, so that the micro laser head 6 needs to be emitted to the upper part of the concave lens 8 through the driving and adjusting angle of the micro speed reducing motor 12, and the real image and the object image are on opposite sides, so that the real image which is refracted by the concave lens 8 is positioned above the concave lens 8; e, when the camera 3 is observed in a head-up mode: the micro laser head 6 emits light through the optical center of the concave lens 8 and emits light along the optical center of the concave lens 8. The auxiliary light source in the rear shell 5 of the display screen 1 is refracted to the outside through the refraction principle of the concave lens 8, and the direction of the face and the camera 3 is changed through observing the position of the light source.
In summary, the concave lens 8 and the convex lens 7 are suitable for the present device, and can be selected and combined according to specific usage situations and requirements or effects, and the following is a specific structure of the rotating mechanism:
and a rotating mechanism:
as shown in fig. 3 of the drawings, the rotating mechanism comprises a rotating frame body and a miniature speed reducing motor 12, wherein the speed reducing motor is an integrated body of a speed reducer and a motor, and the speed reducer can reduce the rotating speed of the motor so as to accurately control the rotating angle of the motor.

The sensor 4 controls the camera 3 to shoot, and the rotating mechanism drives the auxiliary light source to connect and rotate; when the sensor 4 detects the body position, the sensor 4 controls a micro speed reduction motor 12 of the rotating mechanism, the micro speed reduction motor 12 drives an auxiliary light source fixed on a main shaft to rotate, the initial angle of the auxiliary light source which is shot to the lens is changed, and the angle of an auxiliary frame of the auxiliary light source is changed after the auxiliary light source is refracted by the lens; the head looks at the auxiliary frame of auxiliary light source, after the sensor 4 detects that the face gets into the collection frame of camera 3, control carries out the camera 3 and shoots face information, uploads to public security's network system.
