Abstract
The invention relates to a fingerprint input method based on grids. The method includes the following steps: when no fingerprint input exists, a power-supply management module cuts off a main-control-MCU power supply; when a fingerprint sensor detects a fingerprint, firstly the main-control MCU is powered on; after the main-control MCU is powered on, a fingerprint image is read; the main-control MCU judges the position and contact point of a finger on the sensor according to the obtained fingerprint image; when different grids are contacted and turned over, a background image displayed by a display screen is a false fingerprint pattern or other instruction patterns used for prompting a user to adjust a finger press position; and after a complete fingerprint image is obtained, the main-control MCU completes an input process. The fingerprint input method based on the grids has the following effects: through adoption of the method, validity and convenience of fingerprint input are ensured; fingerprint input and display are performed synchronously; the position a fingerprint is indicated directly; and efficiency of fingerprint input and comparison is improved.
Description
Technical field
The present invention relates to work attendance gate inhibition, fingerprint acquisition instrument and mobile security payment technical field, refer in particular to a kind of fingerprint input method based on palace lattice.
Background technology
Along with social development, fingerprint, as everyone distinctive biological characteristic, is more and more applied to the every field in life, comprises education, finance, ecommerce, gate inhibition etc., and even I.D. has also started to store individual finger print information.Therefore the application of fingerprint acquisition instrument is also more and more extensive, but one side fingerprint is protected by the law as individual privacy in addition, agrees to it is arbitrarily storage, typing, transmission, demonstration finger print information without me.This has just caused larger difficulty to fingerprint collecting.
Mostly current fingerprint acquisition instrument is on the market, by multi collect fingerprint image, then to synthesize by algorithm, finally generates fingerprint characteristic and carries out typing, storage, ratio equity.Because Acquisition Instrument can not arbitrarily gather, store, show finger print information, therefore in the time of typing fingerprint, cannot guarantee validity and the integrality of fingerprint typing, cause the success ratio of fingerprint comparison in follow-up use procedure to reduce.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of fingerprint input method based on palace lattice is provided.
The object of the invention is to complete by following technical solution.This fingerprint input method based on palace lattice, the method comprises the steps:
(1), while thering is no fingerprint typing, display screen shows the solid background of multiple palaces lattice, power management module cuts off main control MCU power supply;
(2), in the time that fingerprint sensor detects fingerprint, first notify power management module to power on to main control MCU;
(3), after main control MCU powers on, fetching finger mark image;
(4), main control MCU is according to the fingerprint image obtaining, judgement finger position and the contact point on sensor;
(5), main control MCU is opened the palace lattice of the position that finger touches on display screen according to result of calculation, after each palace lattice are all touched and are opened, the background image that display screen shows is one piece of false fingerprint pattern or other indicator diagram, for pointing out user to adjust finger presses position;
(6), getting after complete fingerprint image, main control MCU completes Input Process.
As preferably, the solid background of described multiple palaces lattice is 15 palace case forms.
The present invention has following effect: adopt method of the present invention, can guarantee validity, the convenience of fingerprint typing.The typing of fingerprint is synchronizeed and is carried out with demonstration; The position of visual indication fingerprint; Improve fingerprint typing and the efficiency of comparing.
Accompanying drawing explanation
Fig. 1 is hardware block schematic diagram of the present invention;
Fig. 2 shows image during without fingerprint typing in the present invention;
Fig. 3 shows image when fingerprint typing in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction:
The defect existing according to current existing fingerprint acquisition instrument, fingerprint acquisition instrument of the present invention comprises sensor, processor, display screen etc., concrete structure block diagram as shown in Figure 1:
Fingerprint sensor: convert finger print to picture signal that main control MCU can be identified;
Main control MCU: major control chip, fetching finger mark sensor image signal is also processed, and controls display screen simultaneously and shows;
Power management module: control system power supply, reduces power consumption when the normal work of assurance system;
Display screen: the relevant information that shows fingerprint typing.
Fingerprint typing flow process:
(1), while thering is no fingerprint typing, display screen shows that the solid background of 15 palace lattice or other backgrounds are (as mistake! Do not find Reference source.Shown in), power management module cuts off main control MCU power supply;
(2), in the time that fingerprint sensor detects fingerprint, first notify power management module to power on to main control MCU;
(3), after main control MCU powers on, fetching finger mark image;
(4), main control MCU is according to the fingerprint image obtaining, judgement finger position and the contact point on sensor;
(5), main control MCU opens the palace lattice of the position that finger touches on display screen according to result of calculation, after each palace lattice are all touched and open, the background image that display screen shows is that one piece of false fingerprint pattern is (as mistake! Do not find Reference source.Shown in) or other indicator diagram, for pointing out user to adjust finger presses position;
(6), getting after complete fingerprint image, main control MCU completes Input Process.
Principle of work of the present invention: when comparison fingerprint, display screen shows the calcspar picture of 15 palace lattice, each palace lattice are pure color or other backgrounds, main control MCU detects on sensor and detects after finger, according to the position of finger, in the time that display screen opens all palaces lattice, display screen shows one piece of fixing false fingerprint pattern, or other indicator diagram, help like this user to adjust fingerprint positions, guarantee that fingerprint comparison is convenient and efficient.Optimal situation is that all palaces lattice are all touched, and like this presents a complete false fingerprint.If some palaces lattice are not touched, that false fingerprint explicitly imperfect.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit; not to circumscription of the present invention; in the situation that not deviating from spirit of the present invention and essence; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all belong in the definite protection domain of claims of the present invention.
