IMAGING INTRUSION DETECTION SYSTEM AND METHOD USING DOT LIGHTING
First Claim
1. An imaging intrusion detection method for an imaging intrusion detection system by using an image recognition technique, the imaging intrusion detection method comprising:
- generating a plurality of collimated light beams by respectively combining condensing lenses with a plurality of light sources and illuminating a security area by the plurality of collimated light beams to form dot lighting;
obtaining a dot image of the security area to which the dot lighting is illuminated by an intrusion monitoring camera and storing the obtained dot image in a memory as reference dot information; and
photographing the security area to which the dot lighting is illuminated at predetermined intervals to obtain an input image, extracting dot information from the input image to compare the dot information with the reference dot information, and determining whether there is intrusion in the security area according to a change of a dot based on a result of comparison.

Abstract
An imaging intrusion detection method combines condensing lenses with a plurality of light sources to form and illuminate a plurality of collimated light beams to a security area as dot lighting. A dot image of the security area to which the dot lighting is illuminated by an intrusion monitoring camera is obtained and stored in a memory as reference dot information. When an input image is obtained by periodically photographing the security area, dot information is extracted from the input image to compare the dot information with the reference dot information, and it is determined whether there is an intrusion in the security area according to a change of a dot based on a result of comparison.
