| Abstract: | A pyroelectric infrared sensor equiped with a multiple reflection optical device was
used to receive the infrared radiation emitted from a human body. By collecting and analyzing the signatures
of the analog signals outputted from the pyroelectric infrared sensor, the location information of the human
body could be extracted. When a person was passing through the area to be observed at a different distance
from the infrared sensing node, the maximum peak of the infrared signal would be decreased with the increasing
of the distance from the person to the infrared sensing node. A novel method for target localization based on
the maximum peak of infrared signals outputted from the pyroelectric infrared sensor was designed. Compared
with the centroid localization algorithm, the maximum localization error of this method was reduced by 87.89 %. |
