Sound collection setting method and sound collection apparatus
A sound collection setting method detects a specific object from an image captured by a camera, obtains position information of the specific object in the image, and sets a sound collection target range of a microphone by changing directivity of the microphone, based on the position information.
1 . A sound collection setting method comprising:
detecting a specific object from an image captured by a camera;
obtaining position information of the specific object in the image;
setting a sound collection target range of a microphone by changing directivity of the microphone, based on the position information;
storing at least one predetermined size of the specific object in a memory; and
obtaining a distance to the specific object as the position information by comparing a size of the specific object included in the image with the at least one predetermined size.
2 . The sound collection setting method according to claim 1 , wherein:
the specific object is an object including a specific image; and
the detecting detects the specific object by detecting the specific image.
3 . The sound collection setting method according to claim 1 , wherein the detecting detects the specific object from the image based on a trained model that has been trained with a relationship between the specific object and the image captured by the camera.
4 . A sound collection setting method comprising:
detecting a specific object from an image captured by a camera;
obtaining position information of the specific object in the image based on a trained model that has been trained with a relationship between the specific object and a position of the specific object; and
setting a sound collection target range of a microphone by changing directivity of the microphone, based on the obtained position information.
5 . The sound collection setting method according to claim 1 , wherein the sound collection target range is fan-shaped or triangular in a plan view, or is conical.
6 . The sound collection setting method according to claim 1 , further comprising setting a non-sound collection target range in part of the set sound collection target range.
7 . The sound collection setting method according to claim 1 , further comprising:
setting a range other than the set sound collection range; and
displaying, distinguishably on a display, the set sound collection target range and the set range other than the sound collection target range.
8 . The sound collection setting method according to claim 1 , wherein the setting sets the sound collection target range according to instructions to set the sound collection target range received from a user.
9 . A sound collection apparatus comprising:
a camera;
a microphone configured so that directivity thereof is changeable; and
a controller configured to:
detect a specific object from an image captured by the camera;
obtain position information of the specific object in the image;
set a sound collection target range of the microphone by changing the directivity of the microphone, based on the position information;
store at least one predetermined size of the specific object in a memory; and
obtain a distance to the specific object as the position information by comparing a size of the specific object included in the image with the at least one predetermined size.
10 . The sound collection apparatus according to claim 9 , wherein:
the specific object is an object including a specific image; and
the controller detects the specific object by detecting the specific image.
11 . The sound collection apparatus according to claim 9 , wherein the controller detects the specific object from the image based on a trained model that has been trained with a relationship between the specific object and the image captured by the camera.
12 . A sound collection apparatus comprising:
a camera;
a microphone configured so that directivity thereof is changeable; and
a controller configured to:
detect a specific object from an image captured by the camera;
obtain position information of the specific object in the image based on a trained model that has been trained with a relationship between the specific object and a position of the specific object; and
set a sound collection target range of the microphone by changing the directivity of the microphone, based on the obtained position information.
13 . The sound collection apparatus according to claim 9 , wherein the sound collection target range is fan-shaped or triangular in a plan view, or is conical.
14 . The sound collection apparatus according to claim 9 , wherein the controller sets a non-sound collection target range in part of the set sound collection target range.
15 . The sound collection apparatus according to claim 9 , further comprising:
a display,
wherein the controller:
sets a range other than the set sound collection range; and
displays, distinguishably on the display, the set sound collection target range and the set range other than the sound collection target range.
16 . The sound collection apparatus according to claim 9 , further comprising:
a communication interface,
wherein the controller sets the sound collection target range according to instructions to set the sound collection target range received from a user via the communication interface.
