Abstract:
1. A monitor for intrusion detection, comprising: detecting means for detecting an intruding object in a 3-dimensional monitoring area and outputting corresponding detection information, setting means for setting information necessary for monitoring a position or actions of the intruding object in the 3-dimensional monitoring area, monitoring information generating means for generating monitoring information concerning the position or actions of the intruding object in the 3-dimensional monitoring area, on the basis of the detection information generated by the detecting means and the setting information by the setting means, and external output means for outputting control output or display output according to the monitoring information concerning the position or actions of the intruding object generated by the monitoring information generating means, and wherein the detecting means include: an optical system employing plural cameras or image pickup elements, wherein the optical axes of the cameras are spaced and parallel, and calculating means for obtaining difference between images obtained from the respective cameras or image pickup elements configuring the optical system in a status without the intruding object and images obtained in a status with the intruding object, and measuring means for measuring the distance to the intruding object by the principle of triangulation on the basis of difference information obtained from the calculation means for each camera or each image pickup element, and thereby outputting distance information to the intruding object measured by the measuring means as the detection information.
