SOUND SOURCE POSITIONING METHOD BASED ON HIGH-PRECISION GPS AND IMPLEMENTATION SYSTEM THEREOF

Document Type and Number:

WIPO Patent Application WO/2019/000680

Kind Code:

A1

Abstract:

A sound source positioning method based on a high-precision GPS and an implementation system thereof. The method comprises the following steps: (1) disposing a microphone array in an arbitrary position in a monitored area, wherein GPS modules are disposed on microphones, and at least four microphones operate simultaneously; (2) the microphones acquiring a sound signal in real time, and the GPS modules acquiring a time signal and a positioning signal in real time; (3) storing the sound signal, the time signal, and the positioning signal; (4) obtaining corresponding data according to an instruction, and calculating a time delay with a TDOA sound positioning algorithm, to solve a sound source position, that is, latitude, longitude and altitude of the sound source; and (5) displaying the sound source position. A high-precision GPS module is combined with a passive sound source positioning method, and the GPS module measures position information of microphones acquiring a sound signal, such that a microphone array used to acquire a sound signal is no longer limited to a fixed relative position.
