Monitoring device composed of united video camera

Abstract

Provided is a monitoring apparatus in which an invading object is magnified and indicated without a dead space by the minimum number of cameras by making a plurality of cameras including a panning / tilting / zooming controllable rotary camera cooperate with each other. The monitoring apparatus comprises the plurality of cameras including the panning / tilting / zooming controllable rotary camera, an invading object recognizing means for processing an image signal from the rotary camera to trace a location of the invading object, a camera function determining means for assigning a tracing function to a first camera for which a predetermined direction of the monitoring target is settled within a photographic range in accordance with the situation of the monitoring target and assigning a wide area photographing function for photographing a monitoring space at a wide angle to a second camera, and a camera control means for controlling the plurality of cameras in accordance with the camera function means, and a camera to detect the monitoring target is switched in accordance with the direction of the monitoring target, so that the invading object is traced without dead angle by the minimum number of cameras.

Description

technical field [0001] The invention relates to a monitoring device which uses a plurality of monitoring cameras and an image processing device to automatically detect intruding objects and enlarge and display them on a screen. Background technique [0002] In recent years, in the field of surveillance, there have been not only systems that display image signals transmitted from cameras on the screen, but also systems that use image processing devices to analyze the signals, determine the location of abnormalities, and prompt other monitors. nearby systems. [0003] As an example of such prior art, there is an example shown in Japanese Unexamined Patent Application Publication No. 11-69342 (Japanese Patent Laid-Open No. 69342 / 1999). This patent document discloses the following system: In order to detect intruders, a camera with a lens having a wide field of view is used, and a rotating camera capable of panning (left and right), pitching (up and do...

AI Technical Summary

Problems solved by technology

As shown in the figure, for example, if the wide-area imaging camera 1102 is installed on the ceiling 1101 and an intruding object is captured while looking down from the ceiling 1101, the area directly below the installation position of the wide-area imaging camera 1102 The area 1103 is not included in the imaging range 1104 of the wide-area imaging camera 1102, and becomes a blind spot, and intruding objects cannot be detected

Therefore, in order to detect intruding objects in the blind spot 1103, it is necessary to install another wide-area imaging camera, which increases the scale of the system.
