Image surveillance apparatus, image surveillance method, and image surveillance processing program
First Claim
1. An image surveillance apparatus, comprising:
- 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, wherein at least one coordinate is designated for defining the surveillance region as a predetermined area of the image less than the entire imagean 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.

12. An image surveillance method using an imaging section which includes a convex mirror having a shape of a body of rotation, the imaging section obtaining an image of an omniazimuthal region, comprising:
-
a surveillance region setting step of setting a desired surveillance region in omniazimuthal image data obtained by the imaging section, the surveillance region setting step including designating at least one coordinate for defining the surveillance region as a predetermined area of the image less than the entire image; a background image setting step of setting a plurality of image data obtained by the imaging section as background image data which are used as a reference that represent a normal state of the surveillance region; and a surveillance step of surveilling the presence/absence of an abnormal event in the surveillance region based on a comparison result between the plurality of background image data and current image data obtained by the imaging section at a predetermined time interval. - View Dependent Claims (13, 14, 15, 16)
