Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
As shown in Figure 1, Fig. 1 is the schematic flow sheet of the first embodiment of the unlock method of the screen of electronic equipment of the present invention.The method comprises the following steps:
Step S101: the screen lighting electronic equipment when user starts setting power key on an electronic device.
In the present invention, power key is preferably arranged on the side of electronic equipment, and certainly, power key also can be arranged on the back side of electronic equipment.Should be understood that when user starts power key, the screen of electronic equipment is lighted, and screen shows palmmprint unlock interface.
Should be understood that before step S101, also comprise the step of the palmmprint of the main frame of electronic equipment being carried out to sample typing, comprising:
A, palm-print image capture.
First user carries out palmmprint scanning with electronic equipment for my two hands, because the palmmprint of each hand is not identical, therefore needs to carry out at least 3-4 scanning, to acquire palmprint image to every hand.
B, palmprint image pre-service.
Noise reduction process is carried out for the palmprint image acquired.
C, default palm print data extract.
From palmprint image, obtain palm print data, and by analog to digital conversion, form the palm print data preset.The palm print data preset comprises size, musculus flexor line features, the crease lines characteristic sum crestal line feature of palmmprint.Palmmprint is the various physiology streaklines on the palm inside surface between wrist and finger, and the physiology and appearance of palmmprint is controlled by gene, even if abrasion for a certain reason, newborn palmmprint streakline still remains original structure.Musculus flexor line is the most obvious 3-5 bar palmmprint line on palm, and it is the key character embodying palmmprint stability and uniqueness, and all one's life of basic people all can not change, and this is the streakline feature of palm.Crease lines is the irregular straight line thinner than musculus flexor line or curve, and being supplementing musculus flexor line, is the textural characteristics of palm.Crestal line is covered in palmmprint surface to be similar to tiny, the regular lines of fingerprint, is the point patterns of palm.Particularly, musculus flexor line features comprises musculus flexor line and is in the coordinate position of palmmprint or the size of musculus flexor line, crease lines feature comprises crease lines and is in the coordinate position of palmmprint or the size of crease lines, and crestal line feature comprises crestal line and is in the coordinate position of palmmprint, the size of crestal line, density or number etc.
D, default palm print data store.
The palm print characteristics data preset are stored in the electronic device, is convenient to the contrast of follow-up palmmprint and uses.
Step S102: the palmprint information being gathered user by the palmmprint acquisition module arranged on an electronic device.
Wherein, palmmprint acquisition module comprises contact palmmprint scanner and/or contactless palmmprint scanner.
Step S103: palm print characteristics data are extracted to palmprint information analysis.
Wherein, palm print characteristics data comprise at least one of the size of palmmprint, musculus flexor line features, crease lines characteristic sum crestal line feature.Certainly, palm print characteristics data can also comprise size, the density between musculus flexor number of lines, crease lines and the density between crestal line of angle between musculus flexor line, musculus flexor line.
Whether step S104: the palm print characteristics data collected and the palm print data preset are contrasted, with the palmmprint of the user judging to collect by comparing result as the palmmprint of the main frame of electronic equipment.
In step S104, when the palm print characteristics data collected reach more than 70% with the similarity of the palm print data preset, judge the palmmprint of the palmmprint of the user collected as the main frame of electronic equipment.Or the palm print characteristics data collected are when belonging to default palm print data a part of completely, judge the palmmprint of the palmmprint of the user collected as the main frame of electronic equipment.
Step S105: if unlock the screen of electronic equipment.
In step S105, if determine that the palmmprint of the user collected is the screen automatic unlocking of the palmmprint of the main frame of electronic equipment, electronic equipment.
As shown in Figure 2, Fig. 2 is the schematic flow sheet of the second embodiment of the unlock method of the screen of electronic equipment of the present invention.Unlock method in Fig. 2 and the unlock method key distinction in Fig. 1 are:
Step S202: send even bar shaped light by least one the contactless palmmprint scanner being arranged on the back side of electronic equipment, to scan the palmmprint of the user covered above at least one contactless palmmprint scanner, thus obtains corresponding palmprint information; And, when the palmmprint of the user determining to collect is the palmmprint not for the main frame of electronic equipment, perform step S206: electronic equipment enters other unlock interface.Wherein, other unlock interface comprise unlock password interface, face recognition unlock interface or sliding trace unlock interface.
