Abstract

A feature of a part or the entirety of a body of a person is detected from a captured video; the person in the video is specified from the detected feature; user information indicating physical features of the person is detected from the feature related to the specified person; motion information including a motion or a gesture with a body and hands of a user is detected from the user information and the captured video; a behavior including the motion of the person is recognized from the motion information and the user information; recognized behavior information is divided for each behavior of the person; the divided behavior information is generated as block data; and the generated block data is transmitted to an outside for each block.

Claims

1. A recognition data transmission device, comprising:

at least one image capturing unit;

a person detection unit that detects a feature of a person from a video captured by the image capturing unit and specifies the person in the video from the detected feature;

a behavior recognition unit that recognizes a behavior of the person, which includes information related to the person and a motion of the person, from the feature related to the person, which is detected by the person detection unit;

a data conversion unit that divides recognition information, which is output by the behavior recognition unit, for each behavior of the person on a time axis, and generates divided block data; and

a transmission control unit that performs control for transmitting the block data, which is output by the data conversion unit, to an outside as recognition data for each block.

2. The recognition data transmission device according to claim 1, wherein

the transmission control unit recognizes, with a time point at which the behavior is finished as a reference, that detection of the behavior is finished, and transmits behavior information in order of finishes of detection.

3. The recognition data transmission device according to claim 2, wherein

the transmission control unit sets a higher priority to behavior information in order of an earlier starting time of a behavior and transmits the behavior information in descending order of priority in a case where the time point at which the behavior is finished is the same.

4. The recognition data transmission device according to claim 1, wherein

in a case where urgent behavior information is detected among the recognition information output by the behavior recognition unit, emergency information indicating emergency is stored in the block data divided for each behavior of the person, and

the transmission control unit performs control so as to transmit the block data having the emergency information before other block data.

5. The recognition data transmission device according to claim 4, wherein

in a case where the urgent behavior information is detected, the behavior recognition unit outputs video data captured by the image capturing unit, which corresponds to the behavior information, and

the transmission control unit transmits the video data corresponding to the urgent behavior information before other block data excluding block data in which the urgent behavior information is stored.
