Fingerprint area of overlap calculation method and electronic device

Calculated fingerprint area of ​​overlap of the present disclosure includes the steps of: collecting be matched fingerprint and get to be matched fingerprint image; Looking feature point matching the pending fingerprint matching template fingerprint image; obtain image feature points of the matching offset; using the image shift amount, to adjust the position of the fingerprint image to be matched in the overlap region to obtain the image to be matched in the template fingerprint in the fingerprint image; counts the number of image pixels of the overlapping region is located to obtain the the overlapping area of ​​the region. Calculation method described above, through the overlap region divided into a pixel points and counting the number of pixels in the area of ​​the overlap region where the calculated overlapping area, more accurately determined area, behind the convenience of calculation, the fingerprint-matching is more accurate, improving user experience. The present invention also discloses an electronic device.
