The invention discloses a biological characteristic collection and recognition system and recognition method, terminal equipment and a storage medium, and the system comprises: an imaging subsystem which comprises an imaging module which is used for carrying out the imaging display of a guide image collected and recognized by biological characteristics in an air target region; a detection module which is used for sending an acquisition trigger signal when it is detected that a target object exists in the aerial target area and the posture of the target object conforms to the guide posture in the guide picture; an acquisition and recognition subsystem which comprises an image acquisition module used for acquiring image information of a target object in the aerial target area in response to the acquisition trigger signal; an image storage module which is used for storing biological characteristic information; and an image processing module which is connected with the image acquisition module and is used for carrying out biological characteristic processing 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 ...
