It is with reference to the accompanying drawings and embodiments, right in order to which the object, technical solution and advantage for making the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, and
It is not used in restriction the application.
It please refers to Fig.1, Fig. 1 is the schematic diagram of an identification system 10 of the embodiment of the present application.Identification system 10 such as one refers to
Line identification system or a face recognition can be used to the biological characteristic according to a user, carry out aspect ratio pair, be carried out with confirming
Whether the biological characteristic of comparison belongs to the user authenticated, and then completes identification flow.Identification system 10 includes a processor 102
And a storage device 104, storage device 104 can store program code, to indicate that processor 102 carries out related running.For reality
Now quick and correct aspect ratio pair carries out identification program with sharp identification system 10, and it is special that the embodiment of the present application provides a kind of biology
Detection method is levied, to complete identification flow.
It please refers to Fig.2, Fig. 2 is the schematic diagram of a biological characteristic testing process 20 of the embodiment of the present application.Testing process 20
Biological characteristic comparison is carried out available for identification system 10.Testing process 20 can be compiled as program code and be stored in storage device
In 104, to indicate that processor 102 performs respective operations, in the examples below that, all using fingermark image as example, at other
In embodiment, the biological characteristic detection method of the application can be used for the detection and knowledge of the user biologicals feature such as face, pupil
Not.Testing process 20 comprises the steps of：
Step 202：Start.
Step 204：According to a quick detection, judge whether fingermark image meets a comparison condition.
Step 206：When fingermark image meets a comparison condition, judge that fingermark image passes through detection.
Step 208：When fingermark image does not meet comparison condition, judge whether fingermark image meets according to a complete detection
Comparison condition.
Step 210：Judge that fingermark image does not pass through detection.
Step 212：Terminate.
According to testing process 20, in one embodiment, identification system 10 is used for detecting fingermark image, in step 204, root
According to quick detection, judge whether fingermark image meets comparison condition, then, when fingerprint matching comparison condition, in step 206
Judge that fingermark image passes through detection.For example, comparison condition can do fingermark image and pre-stored fingerprint template
Compare, judge whether have what is included in fingerprint template in fingermark image, meet certain condition characteristic point or other be used for
Method and condition of image etc. is compared, and it is without being limited thereto.Further, testing process 20 can according to one or more comparison conditions with
It is detected.Then, as described in step 208, when the fingermark image of user does not meet the comparison condition quickly detected (such as refer to
The characteristic point included in schlieren picture is unsatisfactory for preset condition), then judge whether fingermark image meets comparison item according to complete detection
Part.Thus, when the fingermark image of user meets the comparison condition quickly detected, then it can rapidly confirm that fingerprint passes through inspection
It surveys, and when fingerprint does not meet the comparison condition quickly detected, it can still be judged according to complete detection, to ensure to compare just
True property, and then reduce and refuse sincere (False RejectionRate, FRR).
Specifically, quick detection is with the difference completely detected, is quickly detected on and carries out image collection, image processing
And the time span of comparison process, compared to image collection, image processing and the image comparison process completely detected when
Between length it is short.In one embodiment, it is assumed that quick detection with completely detect in image processing and compare above take time phase
Together, also, quick detection has one first detection time length T1, and complete detection has one second detection time length T2.Soon
The time for exposure that speed detects can be shorter carries out image collection, and it is to carry out image with the longer time for exposure to adopt completely to detect
Collection, therefore, the first detection time length T1 are less than the second detection time length T2.In one embodiment, setting completely detects
Time for exposure length is more than twice of quick detection time for exposure length, to increase the inspections of the first detection time length T1 and second
Survey the difference between time span T2.For example, in testing process 20, quick detection is acquired with 20 milliseconds of time for exposure
Fingermark image is to be detected, and when fingermark image meets comparison condition, then judges that fingermark image passes through detection；Conversely, when referring to
When schlieren picture does not meet comparison condition, then fingermark image is resurveyed with 45 milliseconds of time for exposure to be examined by completely detecting
It surveys, and judges whether to meet comparison condition.It can be identical quickly to detect with the comparison condition corresponding to complete detection, will not
Change because of the length of detection time.
In another embodiment, quick detection is adopted from completely detecting detection resolution (resolution) that can be different
Collect fingermark image.Specifically, quick detection has one first detection resolution R1, and there is one second detection to differentiate for complete detection
Rate R2, and the first detection resolution R1 is less than the second detection resolution R2, and therefore, the time that quick detection can be shorter obtains
The fingermark image of low resolution, to carry out aspect ratio pair.That is, in testing process 20, quick detection is with the first inspection
Resolution ratio R1 acquisition fingermark images are surveyed, to carry out the aspect ratio pair of fingermark image, when fingermark image meets comparison condition, are then sentenced
Disconnected fingermark image passes through detection；Conversely, when fingermark image does not meet comparison condition, restart complete detection with higher second
Detection resolution R2 acquires fingermark image, and carries out aspect ratio pair.The quick detection comparison condition corresponding with complete detection can
With identical, that is to say, that be all to detect fingerprint shadow with identical comparison condition no matter the height of acquisition fingermark image resolution ratio
Picture.When fingermark image is by quickly detecting, compared to the time that detection fingermark image can be greatly decreased in complete detection.Such one
Come, the detection method of the application can reduce detection biological characteristic the time it takes in the case of comparison condition is not changed.
It is noted that previous embodiment is to illustrate spirit herein, one skilled in the art works as can
Make appropriate modification according to this.For example, corresponding to quick detection and the different detection time length completely detected or resolution
Rate can be adjusted according to computer system or the demand of user.Alternatively, it can be adjusted according to other detection methods compares item
Part, using the foundation as testing process.Or can with reference to it is quick detect and completely detect as a result, judging characteristic again
Whether comparison condition is met, and it is without being limited thereto, all suitable for the application.
In conclusion the biological characteristic that the application carries out user according to quick detection and complete detection method compares, carry
Efficiency and reduction when height compares are refused sincere.
The foregoing is merely the section Example of the application, not limiting the application, all essences in the application
All any modification, equivalent and improvement made within refreshing and principle etc., should be included within the protection domain of the application.
