Abstract

The invention relates to a sound source positioning system and a sound source positioning method. The sound source positioning system comprises microphones and calculating units, wherein, each microphone respectively senses a target sound source so as to output time domain signals. The calculating units respectively transform all the time domain signals into frequency domain signals and carry out intersectant frequency spectrum calculus according to each frequency domain signal so as to obtain the time differences of arrival and determine the position of the target sound source according to each time difference of arrival and the position of each microphone.

Description

technical field The present invention relates to a positioning system and a positioning method thereof, and in particular to a sound source localization system and a sound source localization method. Background technique In order to locate a target, the conventional method is to use an image positioning system to find out the position of the target. The image positioning system includes an image capture device and an image processing unit. The image capture device is used to capture the image of the target object to be positioned, and output the image data to the image processing unit accordingly. The image processing unit calculates the location of the target object according to the image data output by the image capture device. However, the large data volume of the image signal will cause the processing speed of the image processing unit to be too slow. Furthermore, the hardware requirement of the image positioning system is high, which not only causes high production ...
