Abstract

The invention provides a display device and a sound image figure positioning and tracking method, and the method comprises the steps: obtaining a test audio signal to position a target orientation, calculating a rotation angle according to the target orientation and the current posture of a camera, generating a rotation instruction according to the rotation angle, and transmitting the rotation instruction to the camera. According to the method, the approximate position of a person can be determined by utilizing the spatial perception capability of sound source positioning, the camera is driven to face the sound source direction, then the person detection is carried out on the shot image by utilizing image analysis, the specific position is determined to drive the camera to carry out fine adjustment, accurate positioning is achieved, and the person shot by the camera can be focused and displayed in the image.
