A computer-implemented method for entering human face information into a database, comprising: videoing, by a video capturing unit (204, 304, 404), one or more videoed persons and extracting human face information of the one or more videoed persons from one or more video frames during the videoing; recording, by an audio capturing unit (205, 305, 405), a voice of at least one of the one or more videoed persons during the videoing, wherein the voice of the at least one videoed person comprises identity information of a speaker; performing semantic analysis on the recorded voice so as to extract respective information therefrom, wherein the extracted respective information comprises the identity information of the speaker and is stored in the database as text information and wherein the extracted identity information is different from voiceprint information of the speaker; and associating the extracted information with the human face information of the videoed person who has spoken the extracted information, and entering the associated information into the database, wherein associating the extracted information with the human face information of the videoed person who has spoken the extracted information comprises: determining, by means of the audio capturing unit (205, 305, 405), a direction of the videoed person who has spoken the extracted information in a real scenario with respect to the audio capturing unit (205, 305, 405); mapping the real scenario where the one or more videoed persons are located with a video scenario in terms of location by pre-setting reference markers in the real scenario or by using a ranging function of a camera of the video capturing unit; and determining, based on the direction of the videoed person who has spoken the extracted information in the real scenario, on a relative distance between the audio capturing unit and the video capturing unit, and on positions of the one or more videoed persons in the real scenario relative to the video capturing unit based on the mapping, the position of the videoed person who has spoken the extracted information in the video scenario videoing, by a video capturing unit (204, 304, 404), one or more videoed persons and extracting human face information of the one or more videoed persons from one or more video frames during the videoing;

and determining, based on the direction of the videoed person who has spoken the extracted information in the real scenario, on a relative distance between the audio capturing unit and the video capturing unit, and on positions of the one or more videoed persons in the real scenario relative to the video capturing unit based on the mapping, the position of the videoed person who has spoken the extracted information in the video scenario determining, by means of the audio capturing unit (205, 305, 405), a direction of the videoed person who has spoken the extracted information in a real scenario with respect to the audio capturing unit (205, 305, 405); mapping the real scenario where the one or more videoed persons are located with a video scenario in terms of location by pre-setting reference markers in the real scenario or by using a ranging function of a camera of the video capturing unit; and determining, based on the direction of the videoed person who has spoken the extracted information in the real scenario, on a relative distance between the audio capturing unit and the video capturing unit, and on positions of the one or more videoed persons in the real scenario relative to the video capturing unit based on the mapping, the position of the videoed person who has spoken the extracted information in the video scenario
