Abstract
An image angle variation detection means 81 detects an image angle variation of a imaging device from videos shot by the imaging device based on fixed point information including the position of a fixed point specified by an image angle of the imaging device and the features indicating the characteristics of the fixed point, and a situation determination means 82 determines that the image angle of the imaging device is varied when a change in the image angle variation is stable for a certain period of time.
Claims11
An image angle variation detection device comprising:
- an image angle variation detection unit which detects an image angle variation of an imaging device from videos shot by the imaging device based on fixed point information including the position of a fixed point specified by an image angle of the imaging device and the features indicating the characteristics of the fixed point;
- and
- a situation determination unit which determines that the image angle of the imaging device is varied when a change in the image angle variation is stable for a certain period of time.
An image angle variation detection method comprising:
- detecting an image angle variation of an imaging device from videos shot by the imaging device based on fixed point information including the position of a fixed point specified by an image angle of the imaging device and the features indicating the characteristics of the fixed point;
- and
- determining that the image angle of the imaging device is varied when a change in the image angle variation is stable for a certain period of time.
A non-transitory computer readable information recording medium storing an image angle variation detection program, when executed by a processor, that performs a method for:
- detecting an image angle variation of an imaging device from videos shot by the imaging device based on fixed point information including the position of a fixed point specified by an image angle of the imaging device and the features indicating the characteristics of the fixed point;
- and
