Abstract
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.
