System and method for capturing sound source

A system for capturing a sound source comprising:

• a camera capturing a space where a microphone array is located to generate an image, wherein the microphone array is configured to receive a sound generated by the sound source and generate a sound source coordinate of the sound source relative to the microphone array;
• and
• a computing device electrically connected to the microphone array and the camera, wherein the computing device is configured to search for a sub-image belonging to the microphone array within the image, calculate a microphone coordinate of the microphone array relative to the camera according to the sub-image, calculate a required control parameter at least according to the sound source coordinate and the microphone coordinate, and control the camera to adjust a capturing direction to capture the sound source at least according to the required control parameter;
• wherein the computing device is configured to perform a plurality of instructions for calculating the microphone coordinate of the microphone array relative to the camera according to the sub-image, and the plurality of instructions comprises:
• obtaining at least three non-collinear corner points along an edge of the sub-image;
• adjusting the capturing direction at least three times by the camera, when each of the at least three corner points locates at a specified position of the image, obtaining a control parameter of the camera;
• obtaining length information of the microphone array;
• and
• calculating the microphone coordinate according to the length information and the control parameter.
