Problems solved by technology

[0005] However, in conventional image monitoring equipment, the viewing angle of the imaging device is very narrow, so that the monitoring area covered by a single imaging device is limited. When a large area needs to be monitored, multiple imaging devices must be installed at appropriate positions so that Capable of covering the entire surveillance area with each imaging device

Embodiment Construction

[0039] Next, the image monitoring apparatus of the present invention will be described with reference to the accompanying drawings.

[0040] The image monitoring apparatus of the present invention includes imaging means capable of obtaining images of a large area.

[0041] The imaging device is installed at, for example, an intruder-prevented position of a factory building so as to cover a surveillance area at such a position. If an intruder is detected by the imaging section, the image obtained by the imaging section is subjected to some kind of processing so that the processed image is displayed on a monitor or the like. On the other hand, some output processing required for safety is performed by the monitoring device, such as generating an alarm sound, an alarm signal, and the like.

[0042] The operation modes of the image surveillance device include: a security mode and a deactivation mode. In a normal state, the image monitoring device is set to a safe mode. In the s...

Abstract

An image surveillance apparatus includes: an imaging section including a convex mirror having a shape of a body of rotation, the imaging section obtaining an image of an omniazimuthal region and generating image data of the omniazimuthal region; a surveillance region setting section for setting a surveillance region in the image data of the omniazimuthal region which is obtained from the imaging section; an image processing section for performing image processing according to determination information obtained from a comparison / determination between background image data obtained by the imaging section in advance, which is used as a reference that represents a normal state of the surveillance region, and current image data obtained by the imaging section at a predetermined time interval; and a surveillance information output section for outputting surveillance information according to the determination information.

Description

technical field [0001] The present invention relates to an image surveillance apparatus having an imaging device installed to observe a surveillance area, wherein images obtained by the imaging device are processed to detect persons or objects intruding into the surveillance area. The present invention also relates to an image monitoring method and an image monitoring processing program implemented in such an image monitoring device. Background technique [0002] In recent years, imaging devices such as industrial television cameras (hereinafter referred to as "ITV") have been used in monitoring equipment. These monitoring devices are installed at appropriate places in the factory buildings. The monitoring device monitors images obtained by the imaging device of the monitoring device. Such monitoring equipment has been used effectively to improve the safety of factory buildings by detecting the occurrence of abnormal events and the intrusion of criminals into the factory b...
