By above step, we just obtain the first fingerprint positions when user presses fingerprint identification device 02.Because the fingerprint image that obtained user by fingerprint identification device 02 has been very proven technique in the art, repeat no more in this concrete technology and concrete methods of realizing.Next second fingerprint positions of user will be obtained.
S102, acquisition user, from the first fingerprint positions, are parked in the second fingerprint positions on fingerprint identification device 02 according to the first sense of rotation after rotating in the given time.
About the acquisition of second fingerprint positions of user, its scheme is identical with the acquisition of first fingerprint positions of user.
Preferably, the step that fingerprint identification device 02 obtains the second fingerprint positions comprises:
The second finger print information when S1021, scanning user are parked on fingerprint identification device after rotating according to the first sense of rotation in the given time.
S1022, draw the second image of the relative position of fingerprint on fingerprint identification device 02 according to the second finger print information.
S1023, according to the second spectral discrimination second fingerprint positions.
By above step, we just obtain the second fingerprint positions when user presses fingerprint identification device 02.
S103, judge the anglec of rotation of exclusive fingerprint according to the first fingerprint positions, the second fingerprint positions and the first sense of rotation.
After obtained the first fingerprint positions when user operates on fingerprint identification device 02 (, reference position), the second fingerprint positions (, reference position) and the first sense of rotation (, sense of rotation) by above-mentioned steps, the anglec of rotation that we will utilize the first fingerprint positions (namely, reference position), the second fingerprint positions (namely, reference position) and the first sense of rotation (namely, the sense of rotation) information obtained to calculate user to point.But known by foregoing, for an anglec of rotation, it is the angle determined by reference position, final position and sense of rotation, and for an angle, the angle normally between two lines.The first fingerprint positions that we obtain and the second fingerprint positions are all effigurate images of tool, directly the angle between two images is carried out calculating and being not easy, therefore need us that the angle calcu-lation of two images is converted into the angle calcu-lation of two straight lines.How the angle calcu-lation of two images is converted into the angle calcu-lation of two straight lines, we introduce in detail by by following embodiment.
Preferably, according to the first fingerprint positions, the second fingerprint positions and the first sense of rotation, fingerprint identification device 02 judges that the step of the anglec of rotation of exclusive fingerprint comprises:
First major axis of the central point through the first image of S1031, matching first image.
First, we need to find out the Article 1 straight line carrying out angle calcu-lation.In an embodiment of the present invention, it is all be similar to ellipse that fingerprint due to fingerprint identification device 02 couple of user scans formed fingerprint image, and based on the reason of user's finger shape, finger when rotated, must be for the point of rotation rotates with one end of the major axis of this oval fingerprint image, and, the anglec of rotation of this oval fingerprint image must be identical with the anglec of rotation of the major axis of this ellipse, therefore, based on above-mentioned theory, we using the major axis of oval fingerprint image as the straight line in angle calcu-lation, angle calcu-lation between the major axis angle calcu-lation of oval image being converted into the major axis of the oval fingerprint image of the first picture position and the oval fingerprint image of the second picture position, and using the Article 1 straight line of the major axis of the oval fingerprint image of the first picture position as angle calcu-lation.Therefore, us are needed first to simulate the first major axis of the oval fingerprint image (that is, the first image) of the first picture position.
Second major axis of the central point through the second image of S1032, matching second image.
After have found the Article 1 straight line carrying out angle calcu-lation, we need to find out the Article 2 straight line carrying out angle calcu-lation.Reason is the same, and we are using the Article 2 straight line of the major axis of the oval fingerprint image of the second figure line position as angle calcu-lation.Therefore, us are needed first to simulate the second major axis of the oval fingerprint image (that is, the second image) of the second picture position.
S1033, with the first major axis for starting point, with the second major axis for terminating point, rotate along the first sense of rotation.
Obtain carry out angle calcu-lation Article 1 straight line (namely, first major axis) and Article 2 straight line is (namely, second major axis) after, we need to determine that the sense of rotation (that is, the first sense of rotation) pointed just can calculate the angle between two straight lines.Here, when determining fixing coordinate system, sense of rotation between the two wires only has two selections, clockwise direction rotates and counterclockwise rotates, the sense of rotation selected is different, angle representation between two lines is not identical yet, therefore, needs us to determine for the sense of rotation of finger.After Article 1 straight line (that is, the first major axis), Article 2 straight line (that is, the second major axis) and sense of rotation all determine, just can be easy to calculate the anglec of rotation between two lines.
S1034, using the angle that the turns over anglec of rotation as exclusive fingerprint.
By above interior with known, the anglec of rotation between Article 1 straight line (that is, the first major axis) and Article 2 straight line (that is, the second major axis) is the anglec of rotation of exclusive fingerprint.
