Abstract
The present invention relates to a kind of fingerprint input method based on palace lattice, comprise the following steps：When there is no fingerprint typing, power management module cut-out main control MCU power supply；When fingerprint sensor detects fingerprint, first to electric in main control MCU；In main control MCU after electricity, fingerprint image is read；Main control MCU judges finger position on a sensor and contact point according to the fingerprint image of acquisition；After each palace lattice are all accessible and opened, the background image that display screen is shown is the either other instruction patterns of one piece of false fingerprint pattern, for prompting user to adjust finger pressing position；After complete fingerprint image is got, main control MCU completes Input Process.The present invention has the effect that：Using method of the present invention, validity, the convenience of fingerprint typing can guarantee that.The typing of fingerprint is synchronous with display to be carried out；The position of visual indication fingerprint；Improve fingerprint typing and the efficiency compared.
Description
Technical field
The present invention relates to work attendance gate inhibition, fingerprint acquisition instrument and mobile security payment technical field, refers in particular to one kind and is based on palace lattice
Fingerprint input method.
Background technology
With the development of society, fingerprint is more and more applied in life as everyone distinctive biological characteristic
Every field, including education, finance, ecommerce, gate inhibition etc., or even identity card also has begun to store personal fingerprint letter
Breath.Therefore the application of fingerprint acquisition instrument is also more and more extensive, but still further aspect fingerprint is by law as individual privacy
Protection, without I agree to be can not arbitrarily store, typing, transmission, display finger print information.This is just caused to fingerprint collecting
Bigger difficulty.
Fingerprint acquisition instrument on the market is mostly by multi collect fingerprint image at present, is then synthesized by algorithm,
Ultimately produce fingerprint characteristic and carry out typing, storage, than equity.Because Acquisition Instrument can not gather arbitrarily, store, show that fingerprint is believed
Cease, therefore the validity and integrality of fingerprint typing can not be ensured in typing fingerprint, cause fingerprint ratio during follow-up use
To success rate reduce.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of fingerprint typing side based on palace lattice
Method.
The purpose of the present invention is completed by following technical solution.This fingerprint input method based on palace lattice, should
Method comprises the following steps：
(1) when, without fingerprint typing, display screen shows the solid background of multiple palace lattice, power management module cut-out master control
MCU power supplys；
(2), when fingerprint sensor detects fingerprint, notify power management module to electric in main control MCU first；
(3), in main control MCU after electricity, fingerprint image is read；
(4), main control MCU is according to the fingerprint image of acquisition, judges finger position on a sensor and contact point；
(5), main control MCU opens the palace lattice for the position that finger is touched, Dang Gegong according to result of calculation on a display screen
After lattice are all accessible and opened, the background image that display screen is shown is the either other instruction patterns of one piece of false fingerprint pattern,
For prompting user to adjust finger pressing position；
(6), after complete fingerprint image is got, main control MCU completes Input Process.
Preferably, the solid background of described multiple palace lattice is 15 palace case forms.
The present invention has the effect that：Using method of the present invention, the validity, convenient of fingerprint typing can guarantee that
Property.The typing of fingerprint is synchronous with display to be carried out；The position of visual indication fingerprint；Improve fingerprint typing and the efficiency compared.
Brief description of the drawings
Fig. 1 is the hardware block schematic diagram of the present invention；
Fig. 2 be in the present invention without fingerprint typing when display image；
Display image when Fig. 3 is fingerprint typing in the present invention.
Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：
The defects of being existed according to current existing fingerprint acquisition instrument, fingerprint acquisition instrument of the present invention include sensor, processor, shown
Display screen etc., concrete structure block diagram are as shown in Figure 1：
Fingerprint sensor：Finger print is converted into the picture signal that main control MCU can identify；
Main control MCU：Major control chip, read fingerprint sensor picture signal and handle, while control display screen is shown；
Power management module：Control system power supply, ensure to reduce power consumption while system worked well；
Display screen：Show the relevant information of fingerprint typing.
Fingerprint typing flow：
(1) when, without fingerprint typing, display screen shows the solid background or other backgrounds (as shown in Figure 2) of 15 palace lattice,
Power management module cuts off main control MCU power supply；
(2), when fingerprint sensor detects fingerprint, notify power management module to electric in main control MCU first；
(3), in main control MCU after electricity, fingerprint image is read；
(4), main control MCU is according to the fingerprint image of acquisition, judges finger position on a sensor and contact point；
(5), main control MCU opens the palace lattice for the position that finger is touched, Dang Gegong according to result of calculation on a display screen
After lattice are all accessible and opened, background image that display screen is shown for one piece of false fingerprint pattern (as shown in Figure 3) or other
Instruction pattern, for prompt user adjust finger pressing position；
(6), after complete fingerprint image is got, main control MCU completes Input Process.
The operation principle of the present invention：When comparing fingerprint, display screen shows the block diagram picture of 15 palace lattice, and each palace lattice are pure color
Or other backgrounds, main control MCU detects detect finger on sensor after, according to the position of finger, institute is opened in display screen
When having palace lattice, display screen shows one piece of fixed false fingerprint pattern, or other instruction patterns, so helps user's adjustment
Fingerprint positions, ensure that fingerprint comparison is convenient and efficient.Optimal situation is that all palace lattice are all touched, and is like this presented one
Complete false fingerprint.If palace lattice be not accessible, that false fingerprint it is explicitly imperfect.
Specific embodiment described herein is only to spirit explanation for example of the invention, not to the model of the present invention
Restriction is enclosed, without departing from the spirit and substance of the present invention, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, belong in the protection domain of claims of the present invention determination.
