User's thumb tip to the length L0 in the 1st joint of thumb specific calculating process are roughly the same with Fig. 3, distinctive points
When being to carry out step S302, the 1st joint of thumb is obtained to the distance L of fingerprint sensor top margin1, it is by identifying line computation
's.Assuming that fingerprint sensor identifies the 1st joint region of thumb in nearest fingerprint recognition on the direction of top margin 41
Line is 5, then L1Value be fingerprint recognition line be 5 to top margin 41 distance value.When carrying out step S305, obtain the thumb and refer to
The sharp distance L to the fingerprint sensor top margin3, it is by identifying line computation.Assuming that fingerprint sensor identifies that thumb refers to
Sharp region is 1 in nearest fingerprint recognition line on the direction of top margin 41, then L3Value be that fingerprint recognition line is 2 to top margin

Identification line 55 and identification line 56, identification line 54 intersect with identification line 55 and identification line 56, so as to which sensor is divided into 9
The region of formed objects.Meanwhile between top margin and identification line 55, identification line 55 and identification line 56, identification line 56 and base
Centre position, centre position identification line 57 parallel with it, centre position identification line 58, centre position identification line are set respectively
59。
User's step according to Fig. 3 carries out specific calculating of the thumb tip to the length L0 in the 1st joint of thumb.Carry out
During S302 steps, L1Specific acquisition process be：When fingerprint sensor identifies the 1st joint valley line (i.e. finger-joint print) of thumb
When, according to accessed by S301 steps user input finger print information in crestal line trace information in close to top margin 51 crestal line
Track, by just to the left border originate, via identification line 54, identification line 53, untill border just to the right, progressively enter
Row scanning, the track and which bar identification line near top margin for identifying the crestal line intersect.Wherein,
If intersect still the not side of close top margin 51 with the centre position identification line with certain centre position identification line
Identification line intersect, then judging that the minimum distance calculating of the crestal line and top margin 51 is originated to top margin by the uncrossed identification line is
Only；
If the centre position identification line intersected with identification line still not with the close top margin side of the identification line is intersected,
Judge that the identification line that the minimum distance calculating of crestal line and top margin 51 is intersected by this is originated untill top margin 51.
For example, crestal line first intersects with centre position identification line 58, then fall in identification line 55 and centre position identification line 58
Between, then intersect again with centre position identification line 58, whole scanning process is not intersected with identification line 55, then judges the crestal line
It is calculated as originating untill top margin from identification line 55 with the minimum distance of top margin, i.e. L1=a/3.
When carrying out S302 steps, marked for ease of sampling, the finger-print region that the length apart from top margin 51 is b is known as fingerprint
Other overlay region, while using the fingerprint of the boundary of top margin 51 as Finger-print labelling method line.
When carrying out S304 steps, L2Specific acquisition process be：The fingerprint that fingerprint sensor samples S302 steps is overlapping
Finger print information in cog region is compared with the finger print information that user's S303 steps input again, finds the overlapping cog region of fingerprint
In finger print information, redefine out in the finger print information in the overlapping cog region of fingerprint that this is recognized when sampling for the first time
The Finger-print labelling method line of setting, and the position of fingerprint sensor according to corresponding to this Finger-print labelling method line calculate this Finger-print labelling method line with
The distance L of top margin 512。
If this Finger-print labelling method line overlaps with the identification line of fingerprint sensor, L2Length be since this identification line to top
Distance untill side 51.
If this Finger-print labelling method line falls in the side of close top margin 51 of middle identification line, L2Length be to identify among this
Identification line of the line close to the side of top margin 51 starts the distance untill top margin 51.
If this Finger-print labelling method line falls in the side of close base 52 of middle identification line, L2Length be to identify among this
Identification line of the line close to the side of base 52 starts the distance untill top margin 51.
For example, Finger-print labelling method line falls between middle identification line 58 and base, then judge this top margin fingerprint sampling line with
The distance between top margin L2For the distance between identification line 56 and top margin 51, i.e. L2=(2/3) a.
When carrying out S305 steps, L3Specific acquisition process be：Fingerprint sensor identifies that user is again in S303 steps
Near the fingerprint ridge line (i.e. fingertip fingerprints crestal line) of top margin in the finger print information of input, according to the track of the crestal line, by forward direction
The border starting in left side, via identification line 54, identification line 53, untill border just to the right, is progressively scanned, so as to know
The track and which bar identification line near top margin for not going out the crestal line intersect, and according to above-mentioned calculating L1Computational methods draw finger
The distance L of point and top margin3。
For example, finger tip crestal line intersects with identification line 55, but do not intersect with middle identification line 57, then judge finger tip crestal line
It is to originate distance untill top margin, i.e. L from identification line 55 with the distance of top margin3=a/3.
