A method for obtaining the position of a person in a space of a building via a thermal imager including a wide-angle lens, the method including: acquiring, with the thermal imager, through its wide-angle lens, a deformed thermal image of a scene including the person, the deformed thermal image including a hot zone corresponding to the person present in the scene; extracting a region of interest corresponding to the person from the deformed thermal image using an algorithm; determining the position of the region of interest by identifying the polar coordinates distance r and angle θ of the centre of the region of interest in a polar coordinate system the origin of which is at the centre of the deformed thermal image; and obtaining the actual position of the person by applying a wide-angle correction function to the distance r.

Method for obtaining the position of a person in a room, thermal imager and home automation sensor

A method for counting and for determining the position of people in a room, the method including: activating a thermal imager; the thermal imager capturing a raw thermal image of a scene included in the room; deactivating the thermal imager; after deactivating the thermal imager, acquiring a calibrated thermal image of the scene from the raw thermal image; comparing the calibrated thermal image of the scene with another calibrated thermal image of the scene acquired beforehand; and acquiring the number of people and the position of the people in the room.
