Abstract: 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.

Abstract: An animal appearance determination device comprises: an image data analysis unit which acquires a captured image including cattle being raised in a cattle barn and acquires, as first positional information, a position of an individual cattle in the cattle barn calculated on the basis of an image of the individual cattle in the captured image; a positional data analysis unit which acquires identification information obtained from a sensor device attached to the individual cattle and second positional information indicative of the position of the individual cattle in the cattle barn; and an individual recognition unit which, if the difference between the first positional information and the second positional information is determined to be not more than a predetermined threshold, records the first positional information and the identification information on the second positional information in association with the each other.

Abstract: A data collection device comprises: a data acquisition unit that continuously acquires position information indicating an activity amount of a cow; an identification unit that analyzes the position information of a prescribed time zone and identifies a trend pertaining to changes over time in the activity amount; and a data acquisition amount adjustment unit that adjusts the amount of acquired position information on the basis of the identified trend pertaining to changes over time in the activity amount. The data acquisition unit acquires the position information in line with the acquisition amount adjusted by the data acquisition amount adjustment unit.

Abstract: A driving support system uses information related to objects acquired by a sensor disposed external to a subject vehicle and position information of the subject vehicle to calculate information related to objects in a periphery of the subject vehicle, and provides a warning, position information or distance information to an autonomous driving control unit or a driver of the subject vehicle. A road side information processing unit or a vehicle control unit calculates vehicle periphery information related to objects in the periphery of the subject vehicle, using the information related to objects acquired from the sensor and the position of the subject vehicle detected by the first position detection unit.
