Locating method, locating system, and terminal device

A device, comprising:

• one or more processors;
• memory,
• wherein:
• the device is configured to control a location unit, the location unit includes a microphone array including at least three microphones located at different positions in the microphone array, an infrared sensing array including at least three infrared sensors located at different positions in the infrared sensing array, and an infrared transceiver configured to emit an infrared signal and receive a reflected infrared signal, and
• the memory stores a plurality of instructions that, when executed by the one or more processors, cause the one or more processors to perform the following operations:
• monitoring, by using the microphone array, a sound generated by a monitoring target;
• in response to detecting a sound signal by the microphone array, determining a sound source direction corresponding to detected sound signal according to a sound phase difference obtained by each microphone in the microphone array;
• performing infrared detection in the sound source direction by using the infrared transceiver;
• determining a distance between the monitoring target and the infrared transceiver in the sound source direction according to an infrared detection result obtained by the infrared transceiver;
• and
• generating location information of the monitoring target according to the sound source direction and the distance.
