Device control method, apparatus and system

Abstract

Embodiments of the present application provide a method, apparatus and system for controlling a device. The method is applicable to a video capture device (610) in a sound source localization system. The sound source localization system further includes microphones (620) disposed outside the video capture device (610). The method includes: acquiring a voice signal captured by each of the microphones (620), and acquiring coordinate information of each of the microphones (620) and coordinate information of each of preset positions (S101), calculating a voice power value corresponding to each of the preset positions based on the voice signal captured by each of the microphones (620), the coordinate information of each of the microphones (620) and the coordinate information of each of the preset positions (S102), identifying a preset position with a maximum voice power value, determining the preset position as a position of the sound source, and controlling the video capture device to direct at the position of the sound source (S103). In the present application, microphones (620) are disposed outside the video capture device (610), and the sound in the scene to be captured can all be captured by the microphones (620). Therefore, the accuracy of the sound source localization can be improved, thereby improving the accuracy of the device control.
