Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0043] figure 1 It is a schematic diagram of an implementation environment shown according to an exemplary embodiment. Such as figure 1 As shown, the implementation environment may include a terminal device 110 . For example, the terminal device 110 may be: a mobile phone, a tablet computer, and other terminal devices. Such as figure 1 As shown, the edge side of the terminal devic...

Abstract

The present disclosure relates to a fingerprint identification method and apparatus. The method comprises: when a finger slides on a fingerprint identification panel, reading a plurality of different fingerprint images sensed by the fingerprint identification panel when the finger slides to different positions; performing image stitching on the plurality of different read fingerprint images to obtain a complete fingerprint image; and performing fingerprint identification on the complete fingerprint image. The complete fingerprint image does not need to be obtained only by touching the fingerprint identification panel for once and the method and the apparatus have no special requirement for the size of the fingerprint identification panel, and thus, even if the fingerprint identification panel is narrow, the complete fingerprint image also can be obtained by finger sliding and image stitching to finish fingerprint identification, thereby releasing an available space of terminal equipment.

Description

technical field [0001] The present disclosure relates to the field of fingerprint identification, in particular to a fingerprint identification method and device. Background technique [0002] With the development of fingerprint recognition technology, many terminal devices, such as smart phones, tablet computers, etc., are equipped with fingerprint recognition panels. These terminal devices implement functions such as screen unlocking through fingerprint identification. [0003] In the related art, the size of the fingerprint recognition panel needs to be adapted to the size of the finger. Therefore, there is usually enough space left on the front of the terminal device for setting the fingerprint recognition panel. For example, in many smart phones and tablet computers, the fingerprint recognition panel is arranged under the front display screen of the terminal device. As long as the user touches or presses the fingerprint recognition panel arranged under the front displ...
