Sound source positioning method and apparatus

A non-transitory computer readable medium, comprising a computer program, wherein when the computer program is run on an electronic device, the electronic device is enabled to perform:

• obtaining first location information by using echo data of a radar of the electronic device, wherein the first location information comprises a first angle of an object relative to the radar;
• obtaining an incident angle by using a voice signal captured by a microphone array of the electronic device, wherein the incident angle is an angle at which the voice signal is incident on the microphone array;
• and
• fusing the first angle and the incident angle to obtain second location information, wherein the second location information indicates a location of a sound source generating the voice signal, wherein fusing the first angle and the incident angle to obtain the second location information comprises:
• determining a first weight corresponding to the first angle and a second weight corresponding to the incident angle, wherein the first weight and a moving speed of the object relative to the radar are positively correlated, and
• performing weighted fusion on the first angle and the incident angle based on the first weight and the second weight to obtain a fused angle.

A sound pickup apparatus, comprising:

• a radar configured to:
• transmit a modulated wave, and receive echo data,
• a microphone array comprising at least one microphone, wherein the microphone array is configured to capture a voice signal sent by a sound source, and
• a processor, wherein the radar, the microphone array, and the processor are connected;
• wherein the processor is configured to:
• obtain first location information by using echo data of the radar, wherein the first location information comprises a first angle of an object relative to the radar;
• obtain an incident angle by using a voice signal captured by the microphone array, wherein the incident angle is an angle at which the voice signal is incident on the microphone array;
• and
• fuse the first angle and the incident angle to obtain second location information, wherein the second location information indicates a location of a sound source generating the voice signal by:
• determining a first weight corresponding to the first angle and a second weight corresponding to the incident angle, wherein the first weight and a moving speed of the object relative to the radar are positively correlated, and
• performing weighted fusion on the first angle and the incident angle based on the first weight and the second weight to obtain a fused angle.
