| Abstract: | A system and method for intrusion detection includes an imager directed
towards an object in an interior space. The imager is in data
communication with a computer. The computer is arranged to process
digital three-dimensional image data received from the imager and
programmed to execute a change detection algorithm in response to the
processed three-dimensional data to determine movement of the object. The
computer generates an alarm output in response to detecting movement of
the object above a predetermined threshold. The method includes providing
an imager directed towards an object in an interior space; receiving Time
of Flight signals by the imager; processing digital three-dimensional
image data received from the imager; and executing a change detection
algorithm in response to the processed three-dimensional data to
determine movement of the object. |
