Abstract
To appropriately guide a subject person while protecting a privacy of the subject person despite use of an captured image of the subject person, a guidance system includes: an image capturing unit capable of capturing an image containing a subject person from a first direction; a detection unit that detects a size of an image of the subject person from the image captured by the image capturing unit; and a guidance unit that provides guidance for the subject person based on a detection result of the detection unit.
Claims13
A detection device comprising:
- a first image capture that captures an image containing a subject person from a first direction;
- a second image capture that is separate from the first image capture and captures an image containing the subject person from the first direction;
- an adjuster that adjusts at least one of the first image capture and the second image capture so that a predetermined subject can be contained in a region in which an image capturing region of the first image capture and an image capturing region of the second image capture overlap each other;
- a detector that detects a size of an image corresponding to a head of the subject person by way of image capturing performed by at least one of the first image capture and the second image capture;
- and a determiner that determines a postural state of the subject person based on (i) a relation between a height of the subject person and the size of the image corresponding to the head of the subject person, (ii) identification information of the subject person, and (iii) a change in the size of the image corresponding to the head of the subject person.
A position assessment device comprising:
- an image capture that captures an image containing a subject person from a first direction;
- a detector that detects a size of an image of the subject person and positional information of the subject person in an image capturing region of the image capture from the image;
- and
- a memory that stores positional information of the image capture and stores data in which a position in a floor is related to a height of the floor at the position;
- and
- a determiner that determines a postural state of the subject person based on a (i) the size of the image of the subject person detected by the detector, (ii) the positional information of the subject person, (iii) the positional information of the image capture, and (iv) the data stored in the memory
- wherein the determiner also determines the postural state of the subject person based on a height of the subject person and a size of an image corresponding to a head of the subject person.
