Abstract

A determination apparatus includes: an inputter that receives image information captured by a camera; and a controller that detects a face direction angle of a person while detecting a position of a predetermined body parts of the person based on the image information, and determines a looking-back motion when the face direction angle is larger than a predetermined angle and the predetermined body parts is present in a predetermined position.

Claims

1. A determination apparatus comprising:

an inputter that receives image information captured by a camera; and

a controller that detects a face direction angle of a person while detecting a position of a predetermined body parts of the person based on the image information, and determines a looking-back motion when the face direction angle is larger than a predetermined angle and the predetermined body parts is present in a predetermined position.

2. The determination apparatus according to claim 1, wherein

when the predetermined body parts is present in a predetermined region set in advance, the controller determines that the predetermined body parts is present in the predetermined position.

3. The determination apparatus according to claim 2, wherein

as the predetermined region, a plurality of regions are set.

4. The determination apparatus according to claim 1, wherein

the predetermined body parts includes at least either one of the head or the shoulder.

5. The determination apparatus according to claim 1, wherein

when a duration of a time at which the face direction angle is larger than a predetermined angle is equal to or longer than a predetermined duration, the controller determines that the face direction angle is larger than the predetermined angle.

6. The determination apparatus according to claim 1, further comprising:

an outputter that outputs a result of determination at the controller.

7. A determination method comprising:

receiving image information captured by a camera; and

detecting a face direction angle of a person while detecting a position of a predetermined body parts of the person based on the image information, and determining a looking-back motion when the face direction angle is larger than a predetermined angle and the predetermined body parts is present in a predetermined position.

8. A non-transitory computer-readable recording medium storing a determination program executed in a determination apparatus that determines a looking-back motion of a person, the recording medium storing a determination program that causes a computer to execute:

receiving image information captured by a camera; and

detecting a face direction angle of a person while detecting a position of a predetermined body parts of the person based on the image information, and determining a looking-back motion when the face direction angle is larger than a predetermined angle and the predetermined body parts is present in a predetermined position.
