Abstract
This application provides an in-vehicle user positioning method, an in-vehicle interaction method, a vehicle-mounted apparatus, and a vehicle. In an example, the in-vehicle user positioning method includes: obtaining a sound signal collected by an in-vehicle microphone; in response to that a first voice command is recognized from the sound signal, determining a first user who sends the first voice command; and determining an in-vehicle location of the first user based on a mapping relationship between an in-vehicle user and an in-vehicle location.
Claims15
An in-vehicle user positioning method, comprising:
- obtaining, by an in-vehicle apparatus, a sound signal collected by an in-vehicle microphone;
- in response to that a first voice command is recognized from the sound signal, determining, by the in-vehicle apparatus, a first user who sends the first voice command;
- obtaining, by the in-vehicle apparatus, a mapping relationship between an in-vehicle user and an in-vehicle location;
- determining, by the in-vehicle apparatus, an in-vehicle location of the first user based on the mapping relationship between the in-vehicle user and the in-vehicle location;
- obtaining at least one in-vehicle sound source location by performing sound source positioning based on the sound signal;
- correcting the in-vehicle location of the first user based on the in-vehicle location of the first user and the at least one in-vehicle sound source location, wherein the correcting comprises determining, as a corrected in-vehicle location of the first user, an in-vehicle sound source location that is in the at least one in-vehicle sound source location and that is closest to the in-vehicle location of the first user;
- and
- controlling, by the in-vehicle apparatus, a rotation angle of a projector component based on the corrected in-vehicle location of the first user.

An in-vehicle interaction method, comprising:
- obtaining, by an in-vehicle apparatus, a sound signal collected by an in-vehicle microphone;
- in response to that a first voice command is recognized from the sound signal, determining, by the in-vehicle apparatus, a first user who sends the first voice command;
- obtaining, by the in-vehicle apparatus, a mapping relationship between an in-vehicle user and an in-vehicle location;
- determining, by the in-vehicle apparatus, an in-vehicle location of the first user based on the mapping relationship between the in-vehicle user and the in-vehicle location;
- obtaining at least one in-vehicle sound source location by performing sound source positioning based on the sound signal;
- correcting the in-vehicle location of the first user based on the in-vehicle location of the first user and the at least one in-vehicle sound source location, wherein the correcting comprises determining, as a corrected in-vehicle location of the first user, an in-vehicle sound source location that is in the at least one in-vehicle sound source location and that is closest to the in-vehicle location of the first user;
- and
- executing, by the in-vehicle apparatus, the first voice command based on the corrected in-vehicle location of the first user, wherein executing the first voice command based on the corrected in-vehicle location of the first user comprises:
- controlling, by the in-vehicle apparatus, a rotation angle of a projector component based on the corrected in-vehicle location of the first user.
6 more elements
A vehicle-mounted apparatus, comprising:
- a data storage configured to store a mapping relationship between an in-vehicle user and an in-vehicle location;
- and
- at least one processor coupled with one or more memories that store programming instructions for execution by the at least one processor to:
- obtain a sound signal collected by an in-vehicle microphone;
- in response to that a first voice command is recognized from the sound signal, determine a first user who sends the first voice command;
- obtain the mapping relationship between an in-vehicle user and an in-vehicle location;
- determine an in-vehicle location of the first user based on the mapping relationship between the in-vehicle user and the in-vehicle location;
- obtain at least one in-vehicle sound source location by performing sound source positioning based on the sound signal;
- correct the in-vehicle location of the first user based on the in-vehicle location of the first user and the at least one in-vehicle sound source location, wherein the correcting comprises determining, as a corrected in-vehicle location of the first user, an in-vehicle sound source location that is in the at least one in-vehicle sound source location and that is closest to the in-vehicle location of the first user;
- and
- control a rotation angle of a projector component based on the corrected in-vehicle location of the first user.
