Animal behavior recording device, animal behavior recording method, and program
This animal behavior recording device is provided with a processing unit which acquires animal behavior information, that is, information indicating the behavior of an animal, acquires animal position information, that is, information indicating the positions where the animal is present, estimates the behavior of the animal on the basis of the animal behavior information and the animal position information, and records the behavior in time series. Acceleration data acquired from an acceleration sensor disposed on the animal and/or angular velocity data acquired from an angular velocity sensor disposed on the animal can be used as the animal behavior information, and the processing unit is capable of estimating the behavior of the animal on the basis of one of the animal behavior information and the animal position information and correcting the estimated behavior by using the other information.
