چکیده انگلیسی:
Thermal imaging sensors have been increasingly integrated in a wide range of smart building
and Internet of Things systems. Low-resolution thermal imaging sensors are especially suitable
for applications that require non-intrusive monitoring with proper privacy protection. In this
paper, we present an in-depth investigation of a low-resolution thermal imaging sensor (i.e.,
Melexis MLX90640) focusing on algorithm design issues and solutions when detecting moving
objects. This type of sensors are designed to operate with a two-subpage chessboard reading
pattern, which gives rise to blob displacements across two subpages when target objects are
in motion. We have conducted systematic characterization of the sensor and demonstrated
issues through experimental measurements and analysis. We have also proposed a subpage
bilinear interpolation method and an enhanced sensor data preprocessing method for occupancy
estimation with moving objects. The performance of the proposed method is analyzed by
training and testing classification algorithms using two datasets collected with objects of
different moving speeds. Our performance results indicate that the proposed method could be
used for occupancy estimation in various smart building and Internet of Things applications.
