Abstract
The invention provides a fingerprint input method, which solves the problem that in the prior art, the fingerprint of entry staff cannot be identified due to becoming shallow. The method comprises the following steps of (a) sampling a fingerprint image; step (b), converting an image in an analog form into a digital signal; step (c), pre-storing fingerprint information of the entry staff, including first fingerprint information and second fingerprint information, wherein the fingerprint data of the first finger information is greater than the fingerprint data of the second fingerprint information; comparing the digital signal in step (b) with the first fingerprint information and the second fingerprint information, when the digital signal is matched with the first finger information and the second fingerprint information, outputting a correct tip; when the digital signal is only matched with the second fingerprint information, outputting a correct tip, and updating the first fingerprint information as the digital signal; and when the digital signal is not matched with the first fingerprint information and the second fingerprint information, outputting an error tip.
Description
Technical field
The present invention relates to field of biological recognition, particularly a kind of fingerprint input method.
Background technology
The fingerprint punched-card machine generally is used for attendance, logs in personnel's fingerprint but existing fingerprint punched-card machine often can occur and shoals and the situation of None-identified, needs again typing fingerprint.
Summary of the invention
The present invention proposes a kind of fingerprint input method, has solved in the prior art owing to the fingerprint that logs in personnel shoals and the None-identified problem.
Technical scheme of the present invention is achieved in that
A kind of fingerprint input method may further comprise the steps: step (a), sample finger images; Step (b) is digital signal with the image transitions of analog form; Step (c), the pre-stored finger print information that logs in personnel comprises the first finger print information and the second finger print information, the finger print data of the first finger print information is more than the finger print data of the second finger print information; Digital signal in the step (b) is compared with the first finger print information and the second finger print information, and when described digital signal was all mated with the first finger print information and the second finger print information, output is prompting correctly; When described digital signal only was complementary with the second finger print information, output is prompting correctly, and the first finger print information is updated to described digital signal; When described digital signal is not all mated with the first finger print information and the second finger print information, the output error prompting.
Alternatively, the step of described sample finger images is specially by the CDD camera and takes fingerprint image.
The invention has the beneficial effects as follows: store two cover finger print informations, after matching degree requires the first higher finger print information None-identified, with current finger print data it is upgraded, saved manpower.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of a kind of fingerprint input device of the present invention;
Fig. 2 is the process flow diagram of a kind of fingerprint input method of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of fingerprint input device of the present invention comprises: the camera 10 that is used for sample finger images; Analog image is converted to the analog to digital converter 20 of digital signal, is connected to the output terminal of camera 10; Store the storer 50 that logs in personnel's finger print information, each logs in personnel and stores the first finger print information and the second finger print information, the finger print data of the first finger print information is more than the finger print data of the second finger print information, and namely the matching degree of the first finger print information finger print data requires higher; Dsp processor 30, receive the digital signal of analog to digital converter 20 outputs, compare with the finger print information in the storer 50 by comparer 40, when finger print data all mates with the first finger print information and the second finger print information, the correct prompting of output, when finger print data only was complementary with the second finger print information, output is prompting correctly, and the first finger print information in the updated stored device 50.
Preferably, camera 10 is the CDD camera, can realize taking into account of picking rate and sharpness.Dsp processor 30 is the TMS320F2812 processor.
The invention allows for a kind of fingerprint input method, as shown in Figure 2, may further comprise the steps: step (a), sample finger images; Step (b) is digital signal with the image transitions of analog form; Step (c), the pre-stored finger print information that logs in personnel comprises the first finger print information and the second finger print information, the finger print data of the first finger print information is more than the finger print data of the second finger print information; Digital signal in the step (b) is compared with the first finger print information and the second finger print information, and when described digital signal was all mated with the first finger print information and the second finger print information, output is prompting correctly; When described digital signal only was complementary with the second finger print information, output is prompting correctly, and the first finger print information is updated to described digital signal; When described digital signal is not all mated with the first finger print information and the second finger print information, the output error prompting.
Preferably, the step of sample finger images is specially by the CDD camera and takes fingerprint image.
The invention has the beneficial effects as follows: store two cover finger print informations, behind demanding the first finger print information None-identified of matching degree, with current finger print data it is upgraded, saved manpower.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
