The invention discloses a remote iris tracking and acquiring method based on a microphone array, which includes the following steps: S1, a sound source locating module of a microphone array is started according to the voice of a user distributed within the voice acquisition range of the distributed microphone array, and tracks and calculates the position information of the mouth of the user in a three-dimensional space in real time; S2, the sound source locating module transmits the position information to a central processing control module, and if the position information is within the work range of an infrared camera and a holder, the central processing control module makes a high-speed holder and zoom module of the infrared camera aligned with the head of the user for zoom-in focus shooting to get multiple infrared images of the head of the user; and S3, a voice wakeup module identifies whether the current user voice is an agreed wakeup word according to the voice; if the current user voice is not an agreed wakeup word, the voice is invalid, and the infrared images are ignored; and if the current user voice is an agreed wakeup word, the voice is valid, and the infrared images collected are used in iris recognition. The remote iris tracking and acquiring method of the invention has the advantages of high accuracy, high practicability and high verification speed.
