Accident detection device and accident detection method
An accident detection device is provided with: a possession detection unit that uses a photographed images from a surveillance camera to detect a person and a possession, which is an object possessed by the person; and an accident determination unit that determines whether an accident has occurred on the basis of movement of the person and the possession in the photographed images from the surveillance camera.
1. An accident detection system, comprising:
a camera device that captures an image of a predetermined area; and
an accident detection apparatus that includes a processor, the processer receiving, via a network, the image of the predetermined area captured by the camera device, and the processor detecting an occurrence of an accident using the image of the predetermined area, wherein
the processor:
detects a person and a possession which is an object in the possession of the person by using the image of the predetermined area;
determines whether the accident has occurred, based on movements of the person of the predetermined area; and
determines whether the accident has occurred based on a movement of the possession, when the processor determines that no accident has occurred based on the movements of the person.
2. The accident detection system according to claim 1 , wherein
the processor outputs a determination that the accident has occurred and outputs an image used for the determination when the processor determines that the accident has occurred.
3. The accident detection system according to claim 1 , wherein
the processor outputs a determination that the accident has occurred and outputs an image which is being captured by the camera device that has captured the image used for the determination, when the processor determines that the accident has occurred.
4. The accident detection system according to claim 1 , wherein
the processor outputs a determination that the accident has occurred and outputs information on an accident that had occurred previously at a place where the image used for the determination has been captured, when the processor determines that the accident has occurred.
5. The accident detection system according to claim 1 , wherein:
an image used by the processor for determination of occurrence of the accident is an image captured later than an image used for detection of the possession.
6. The accident detection system according to claim 1 , wherein:
the camera device includes a plurality of cameras, and
a camera which captures an image used by the processor to detect the possession is different from a camera which captures an image used by the processor to determine the occurrence of the accident.
7. The accident detection system according to claim 1 , wherein:
the processor determines that the accident has occurred when detecting a movement such as a fall or dropping of the possession from the image.
8. An accident detection method, comprising:
receiving, by a processor, via a network, an image of a predetermined area captured by a camera device;
detecting, by the processor, an occurrence of an accident using the image of the predetermined area;
detecting, by the processor, a person and a possession which is an object in the possession of the person by using the image of the predetermined area;
determining, by the processor, whether the accident has occurred, based on movements of the person in the image of the predetermined area; and
determining, by the processor, whether the accident has occurred based on a movement of the possession, when determining that no accident has occurred based on the movements of the person.
