Wearing detection apparatus, imaging apparatus, restraint device, and wearing detection program
According to one embodiments, a wearing detection apparatus includes a restraint device, an imaging device, a control unit, and an output device. The restraint device is to restrain a passenger seated in a seat, and includes a strap an exposed area of which changes when the strap is being worn and not worn. The imaging device captures an image of the restraint device including the strap. The control unit detects from the image captured by the imaging device, a recognition image corresponding to a recognition member provided in an area that is exposed when the strap is worn. The output device outputs a result of detection of the recognition image.
1. A wearing detection apparatus comprising:
a restraint device configured to be used for restraining a passenger seated in a seat, the restraint device including a strap, an exposed area of which changes when the strap is being worn and not worn, the strap having a first region pulled to a position above a shoulder of the passenger seated in the seat and a second region in vicinity of a fixture at a time of the passenger wearing the strap, wherein recognition members are attached to the first region and the second region;
an imaging device configured to capture an image of the restraint device including the strap; and
a control unit configured to detect, from the image captured by the imaging device, a first recognition image corresponding to the recognition member attached to the first region in the image and a second recognition image corresponding to the recognition member attached to the second region in the image, and output a result of detection indicating that the restraint device is being worn when both the first recognition image and the second recognition image are detected, wherein
the recognition members include a specific pattern,
a plurality of seats and a plurality of restraint devices are arranged,
the recognition members have patterns that differ between the restraint devices,
the imaging device captures the image of the restraint devices including the straps, and
the control unit detects the first recognition image and the second recognition image for each of the restraint devices, and outputs the detection result indicating whether the restraint device is being worn when both the first recognition image and the second recognition image for each respective restraint device are detected.
2. A camera unit comprising:
an imaging device configured to capture an image of a restraint device including a strap with light of a specific wavelength outside the visible light spectrum, wherein the restraint device is configured to be used for restraining a passenger seated in a seat, an exposed area of the strap changes when the strap is being worn and not worn, the strap has a first region pulled to a position above a shoulder of the passenger seated in the seat and a second region in vicinity of a fixture at a time of the passenger wearing the strap, and recognition members are attached to the first region and the second region; and
a detection circuit configured to detect, from the image captured by the imaging device, a first recognition image corresponding to the recognition member attached to the first region in the image and a second recognition image corresponding to the recognition member attached to the second region in the image, and output a result of detection indicating that the restraint device is being worn when both the first recognition image and the second recognition image are detected, wherein
the recognition members include a specific pattern,
a plurality of seats and a plurality of restraint devices are arranged,
the recognition members have patterns that differ between the restraint devices,
the imaging device captures the image of the restraint devices including the straps, and
the detection circuit detects the first recognition image and the second recognition image for each of the restraint devices, and outputs the detection result indicating whether each said restraint device is being worn when both the first recognition image and the second recognition image for each respective restraint device are detected.
3. A non-transitory computer-readable storage medium having stored thereon a wearing detection program which is executable by a computer, when executed, cause a computer to:
instruct an imaging device to capture an image of a restraint device including a strap, an exposed area of which changes when the strap is worn and when the strap is not worn, the strap having a first region pulled to a position above a shoulder of the passenger seated in the seat and a second region in vicinity of a fixture at a time of the passenger wearing the strap, wherein recognition members are attached to the first region and the second region, wherein
the recognition members include a specific pattern,
a plurality of seats and a plurality of restraint devices are arranged, and
the recognition members have patterns that differ between the restraint devices and the imaging device is instructed to capture the image of the restraint devices including the straps;
detect for each of the restraint devices, from the image captured by the imaging device, a first recognition image corresponding to the recognition member attached to the first region in the image and a second recognition image corresponding to the recognition member attached to the second region in the image, and
output a result of detection indicating whether each restraint device is being worn when both the first recognition image and the second recognition image for each respective restraint device are detected.
