Claim 0:
1. A facial recognition method, comprising:
capturing a facial image, extracting a facial feature, matching the facial feature against a plurality of pre-stored original images separately to obtain a first required comparison value, and matching the facial feature against a plurality of pre-stored captured-on-site images separately to obtain a second required comparison value;
determining whether the first required comparison value and the second required comparison value are greater than or equal to a preset comparison threshold;
in response to determining that the first required comparison value is less than the preset comparison threshold and the second required comparison value is also less than the preset comparison threshold, re-extracting a facial feature, matching the re-extracted facial feature against the plurality of original images separately to obtain a third required comparison value, and determining whether the third required comparison value is greater than or equal to the preset comparison threshold; and
in response to determining that the third required comparison value is greater than or equal to the preset comparison threshold, saving the facial image as a new captured-on-site image for updating of the plurality of pre-stored captured-on-site images, refreshing a number of successful comparisons of the captured-on-site image, and determining that the recognition is successful.
