US 12,627,941 B2 · Tracking control method and apparatus, storage medium, and computer program product

Abstract

Embodiments of this application disclose a tracking control method. When a sound source object makes a sound, a control device determines an azimuth θ1 of the sound source object relative to a first microphone array based on detection data of the first microphone array, and determines an azimuth θ2 of the sound source object relative to a second microphone array based on detection data of the second microphone array. The control device determines a location of the sound source object based on the azimuth θ1, the azimuth θ2, a location of the first microphone array, and a location of the second microphone array. The control device controls, based on the location of the sound source object, a camera to shoot the sound source object to obtain a tracking video image. According to this application, a speaker can be accurately recognized, to improve accuracy of automatic tracking.
