Abstract

The invention discloses a biological characteristic acquisition and identification system and identification method, a terminal device and a storage medium, the biological characteristic acquisition and identification system comprises an imaging subsystem and an acquisition and identification subsystem, the imaging subsystem comprises an imaging module and a detection module, and the imaging module comprises a display, an optical assembly and a main control unit. The detection module sends an acquisition trigger signal, and the main control unit responds to the acquisition trigger signal to control a backlight assembly of the display to emit illumination light in a preset mode; the image acquisition module comprises at least one image acquisition unit, an illumination unit and a control unit, the illumination unit and the display are arranged on the same side of the optical assembly, and the image acquisition unit is used for acquiring image information of a target object in an aerial target area in response to an acquisition trigger signal; and the image processing module is used for obtaining biological characteristic information or identifying the identity of the user according to the image information. The collection and recognition system is more convenient in operation mode, and can avoid the risk that a user touches equipment during operation.

Description

technical field [0001] The present invention relates to the technical field of imaging recognition, in particular to a biometric feature collection and recognition system, a terminal device, a biometric feature collection and recognition method, and a storage medium. Background technique [0002] In related technologies, a fingerprint identification system collects fingerprint images by using a contact-type optical sensor or a capacitive sensor, and uses a minutiae-based matching algorithm to perform fingerprint matching. Among them, the minutiae matching algorithm is very sensitive to the quality of the fingerprint image, but the fingerprint image acquisition device based on the contact sensor cannot guarantee the image quality, and has the disadvantages of small fingerprint area, low resolution, and insufficient feature points. In addition, this method relies on physical contact between the finger and the fingerprint sensing device, but the requirement to place the finger ...
