Monitoring system and camera terminal

Abstract

There is provided a monitoring system capable of flexibly coping with a change of system configuration and having a high monitoring capability. The monitoring system includes a plurality of camera terminals (01, 01b) connected by a communication medium (02). The plurality of camera terminals include: an imaging element (04) for imaging an imaging region included in a monitoring range and having means for modifying the imaging region; a communication unit (03) for transmitting imaging characteristic information as information specifying an imaging region, via a communication medium (02) to another camera terminal and receiving imaging characteristic information from the another terminal; and an imaging characteristic modification unit (05) for modifying the imaging region by controlling the imaging element (04) of the camera terminal so that the imaging region of the camera terminal and the imaging region of the another camera terminal are in a predetermined relationship according to the imaging characteristic information from the camera terminal and the imaging characteristic information from the another camera terminal received by the communication unit (03).

Description

[0001] The application of the present invention is a divisional application submitted by the applicant on January 18, 2005, the application number is 200580004014.X, and the title of the invention is "surveillance system and camera terminal". technical field [0002] The present invention relates to a monitoring system composed of a plurality of camera terminals, and in particular to a monitoring system capable of monitoring the entire monitoring area and in which each camera terminal cooperates with surrounding camera terminals. Background technique [0003] By using multiple cameras, it is possible to perform high-function surveillance that cannot be realized with only one camera. [0004] Conventionally, as a monitoring system using a plurality of cameras, there is a technique disclosed in Patent Document 1, for example. figure 1 It is a structural diagram of an apparatus for automatically adjusting the detection areas of multiple cameras described in Patent Document 1. ...

Problems solved by technology

[0015] In addition, in the conventional technologies disclosed in the above-mentioned Patent Documents 1 to 4, since different tasks are assigned to each of the plurality of cameras, there is also a problem that monitoring blind spots are likely to occur, and the monitoring capability is insufficient.

[0016] For example, in the plurality of mobile cameras 10 constituting the monitoring system disclosed in the above-mentioned Patent Document 2, by moving along the track of the guide rail 20 in the monitoring area and taking pictures of the monitoring area within a certain period of time, although the monitoring area can be captured Surveillance with fewer blind spots, but cannot use all mobile cameras to continuously monitor the surveillance area at the same time

Therefore, for example, when an intruder always moves to an area that becomes a blind spot of the mobile camera 10 according to the movement of the mobile camera 10, the surveillance system cannot find the intruder.
