Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a mobile phone unlocking method of the present invention, and as shown in fig. 1, the mobile phone unlocking method of the present embodiment includes:
102, acquiring the fingerprint image through an image acquisition unit, and sending the fingerprint image to a server;
103, the server reverses the black and white color of the fingerprint image to generate an image to be engraved, and sends the image to be engraved to a laser engraving machine;
104, receiving the image to be engraved by the laser engraving machine, and engraving a fingerprint on finger mould silica gel according to the image to be engraved;
and 105, unlocking the mobile phone by using the engraved user fingerprint finger mold silica gel.
Specifically, in the method for unlocking a mobile phone of this embodiment, the fingerprint information of the user on the mobile phone is collected first, and the dust on the surface of the mobile phone can be flicked off by using a fine and soft brush. The dust is originally stuck in the fingerprint lines by sweat, and after the dust is removed, a clean transparent adhesive tape is pressed on the fingerprint of the screen. And the transparent adhesive tape is taken off from the screen, so that the fingerprint of the user on the mobile phone is obtained. The fingerprint is a screen locking fingerprint preset by the mobile phone user. And shooting the fingerprint image on the transparent adhesive tape through a camera to obtain the fingerprint image. And sends the image to the server. The server may be a local PC or a remote processor. The server receives the fingerprint image and then reverses the black and white color of the fingerprint image, namely, the raised grains of the fingerprint are converted into white. The depressed lines of the fingerprint turn black. And the image that will convert sends to laser engraving machine, and laser engraving machine carries out the fingerprint sculpture according to the black lines of sunken line on indicating mould silica gel. The carved finger-mould silica gel can be used for unlocking the mobile phone.
The server also needs to detect the integrity and sharpness of the fingerprint image before performing black-and-white color reversal of the fingerprint image. Whether the fingerprint image is complete or not is judged through the profile tolerance of the fingerprint image, and if the fingerprint image is incomplete, a plurality of fingerprint images are adopted for fusion. The integrity of the images is further completed through the fusion of a plurality of images. If the fingerprint image is not complete, the definition of the fingerprint image is judged according to the line contact ratio and the consistency of the fingerprint, if the definition of the fingerprint image is not enough, the same area of another fingerprint image is selected for integral replacement, namely the fuzzy fingerprint image area is integrally replaced with the same area of the other fingerprint image. And detecting whether the definition and the texture consistency of the fingerprint image after replacement meet preset requirements or not after replacement. The accuracy is improved for the subsequent fingerprint carving work of the finger mould silica gel through the completeness supplement and definition proofreading of the fingerprint image.
Further, before the fingerprint carving is performed on the finger mould silica gel according to the carving image, the method further comprises the following steps:
filling liquid into the thin-caliber silicone tube, and sealing two sections of the thin-caliber silicone tube filled with the liquid;
winding the sealed silicone tube into a dough shape at random, and placing the dough into a finger-shaped mould;
and dripping the molten finger-membrane silica gel into the fingerprint mold to form the finger-membrane silica gel to be burned.
Specifically, the finger-mold silicone of the present embodiment is added with a globoid silicone tube for simulating blood flow, and the silicone tube is a small-diameter silicone tube. The inner part is filled with liquid, a part of air is reserved in the small-caliber silicone tube when two ends of the small-caliber silicone tube filled with the liquid are sealed, and the small-caliber silicone tube is pressed when the blood flow simulation device is used, so that the liquid has relative position change, a flow feeling is formed, and the blood flow simulation degree is improved. The silicone tube is in a ball shape, can be wound irregularly, and does not need to limit the winding mode. And putting the bulk silicone tube into a finger-shaped mold, and dripping the molten finger-mold silicone into the fingerprint mold, thereby finishing the finger-mold silicone to be recorded. The silicone tube can flow along with pressure when the finger-mould silica gel identifies the fingerprint by the mobile phone, so that the fitting degree of the finger-mould silica gel and a mobile phone screen is improved, and the fingerprint is better contacted with the mobile phone. The recognition of the mobile phone to the finger-mode silica gel is enhanced.
Further, the distance between the small-aperture silicone tube in the shape of a ball and the surface to be recorded of the finger-membrane silicone rubber to be recorded is 0.15-0.25 mm.
Specifically, in this embodiment, the distance between the rounded thin-caliber silicone tube and the surface to be recorded of the finger-membrane silicone rubber is 0.15-0.25 mm, which is the same as the distance between the finger vein of the fingertip of the human body and the skin, and at this distance, the rounded silicone tube inside the finger-membrane silicone rubber can more accurately realize the simulation of the blood flow inside the finger-membrane silicone rubber. The simulation degree of the finger-mould silica gel is improved, so that the accuracy of unlocking by the silica gel fingerprint is improved.
Further, the filling liquid includes: gelatin, normal saline or dextran, hydroxyethyl starch and gelatin mixture.
Specifically, the filling liquid in the small-aperture silicone tube in the form of a dough in this embodiment is gelatin, normal saline or a mixture of dextran, hydroxyethyl starch and gelatin, and the ratio of the dextran to the hydroxyethyl starch to the gelatin to the normal saline in parts by weight is 1:3:8: 20.
In the embodiment, the flow rate of the liquid corresponding to the composition of the liquid in the silicone tube is close to the blood flow rate of a human body, so that the simulation degree of the blood flow in the finger-model silicone is improved. The accuracy of silica gel fingerprint unblanking is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
