Abstract
An estimation method includes obtaining first sound information regarding a reflected sound resulted from reflection of a transmission sound in an inaudible band inside a facility, and outputting image information indicating a living body presence area in which a living body is present, by inputting the first sound information obtained to a first trained model trained using sound information regarding the reflected sound and an image indicating the living body presence area.
Claims20
An estimation method for estimating a living body inside a facility, the estimation method comprising:
- obtaining first sound information regarding a reflected sound resulted from reflection of a transmission sound in an inaudible band inside the facility;
- outputting image information indicating a living body presence area in which the living body is present, by inputting the first sound information obtained in the obtaining of the first sound information to a first trained model trained using sound information regarding the reflected sound and an image indicating the living body presence area;
- and
- outputting behavior information indicating a behavior of the living body inside the facility, by inputting the image information output in the outputting of the image information to a second trained model trained using the image information indicating the living body presence area and behavior information indicating a behavior of the living body.
An estimation system that estimates a living body inside a facility, the estimation system comprising:
- a first sound information obtainer that obtains first sound information regarding a reflected sound resulted from reflection of a transmission sound in an inaudible band inside the facility;
- a living body presence area estimator that outputs image information indicating a living body presence area in which the living body is present, by inputting the first sound information obtained by the first sound information obtainer to a first trained model trained using sound information regarding the reflected sound and an image indicating the living body presence area;
- and
- a living body behavior estimator that outputs behavior information indicating a behavior of the living body inside the facility, by inputting the image information output by the living body presence area estimator to a second trained model trained using the image information indicating the living body presence area and behavior information indicating a behavior of the living body.
