Problems solved by technology

Due to the large amount of interference encountered in the process of fingerprint image collection and the huge amount of data carried in the fingerprint image, the algorithm complexity of the CPU processing the fingerprint image increases, especially in tricky scenarios such as low temperature, dry fingers, and direct sunlight. The processing efficiency of the CPU for the fingerprint image is significantly reduced, and it is difficult to meet the needs of fingerprint identification.

Embodiment Construction

[0059] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0060] The embodiment of the present application only takes the optical fingerprint system as an example for illustration, but it should not constitute any limitation to the embodiment of the present application. The embodiment of the present application is also applicable to other fingerprint recognition systems such as capacitive fingerprint systems and ultrasonic fingerprint systems, as long as it can realize The collection of fingerprint images is enough.

[0061] In the process of optical fingerprint identification, the fingerprint sensor (or called image sensor, etc.) collects the light emitted by the light source incident on the finger and the light signal reflected by the finger, so as to obtain the fingerprint image of the finger. The fingerprint image carries the fingerprint information of the finger, and the fingerprint ...

Abstract

The embodiment of the invention provides a fingerprint recognition method which can improve the fingerprint recognition efficiency. The method comprises the steps that a main processor receives firstfeature data, sent by a coprocessor, of a fingerprint image obtained by processing the fingerprint image of a finger through the coprocessor; and the main processor carries out fingerprint recognitionaccording to the first feature data of the fingerprint image.

Description

technical field [0001] The present application relates to the field of information technology, and more specifically, to a fingerprint identification method, processor and electronic equipment. Background technique [0002] The fingerprint identification technology is to collect a fingerprint image of a finger through a fingerprint sensor, and perform fingerprint identification based on the fingerprint image through a central processing unit (Central Processing Unit, CPU). Due to the large amount of interference encountered in the process of fingerprint image collection and the huge amount of data carried in the fingerprint image, the algorithm complexity of the CPU processing the fingerprint image increases, especially in tricky scenarios such as low temperature, dry fingers, and direct sunlight. The processing efficiency of the CPU on the fingerprint image is significantly reduced, and it is difficult to meet the needs of fingerprint identification. Contents of the inven...
