Abstract
The invention relates to an inspection method of a shoe worn by a foot of an individual comprising the following steps: acquiring (S1) a thermal image of the shoe when it is worn by a foot of the individual by means of a thermal camera, determining (S2), from the thermal image of the shoe, a lower limit of the foot of the individual, determining (S3) a position of the shoe relative to the thermal camera at the time of acquisition of the thermal image, and deducing (S4) of the position of the shoe relative to the camera and of the lower limit of the foot, a distance between the lower face of the sole and the lower face of the foot of the individual.
Claims22
An inspection method comprising:
- acquiring, at a first time, a thermal image of a shoe by means of a thermal camera when the shoe is worn by a foot;
- determining, from the thermal image of the shoe, of a lower limit of the foot, said lower limit corresponding to a lower face of the foot;
- determining a position of the shoe relative to the thermal camera at the first time;
- and
- deducing from the position of the shoe relative to the thermal camera and from the lower limit of the foot a distance between a lower face of the sole and the lower face of the foot.
An inspection system comprising:
- a base configured to receive a foot of an individual covered by a shoe worn by an individual;
- a thermal camera configured to acquire a thermal image of the shoe;
- means configured to determine a position of the shoe relative to the thermal camera;
- and
- a processor configured to determine, from the thermal image of the shoe, a lower limit of the foot, said lower limit corresponding to a lower face of the foot, and to deduce a distance between the lower face of the sole and the lower face of the foot from the position of the shoe relative to the thermal camera and from the lower limit of the foot.
A detection assembly comprising:
- a base configured to receive a foot of an individual covered by a shoe worn by an individual;
- a thermal camera configured to acquire a thermal image of the shoe;
- means configured to determine a position of the shoe relative to the thermal camera;
- and
- a processor configured to determine, from the thermal image of the shoe, a lower limit of the foot of the individual, said lower limit corresponding to a lower face of the foot, and to deduce a distance between the lower face of the sole and the lower face of the foot from the position of the shoe relative to the thermal camera and from the lower limit of the foot;
- and at least one of:
- a body scanner comprising detection means of a target object by means of one or more radiation energy modulated or emitted by a body of the individual;
- a detector device comprising means adapted to detect stratification by vertical stacking, in the sole, by detection of successive echoes following emission of waves towards the sole;
- and,
- measuring means of electrical capacitance formed by the sole of the shoe.
