MONITORING SYSTEM AND MONITORING METHOD
First Claim
1. A monitoring system for monitoring around, comprising:
- a first camera having a fish-eye lens;
a second camera having a fish-eye lens and disposed opposite to said fish-eye lens of said first camera in a direction to face each other;
image data extracting means for extracting first and second frame data corresponding to a monitoring range from first image data captured by said first camera and second image data captured by said second camera; and
image combining means for generating combined frame data corresponding to said monitoring range by combining said first and second frame data extracted by said image data extracting means.

Abstract
A first camera 12 having a fish-eye lens 13 and a second camera 14 having a fish-eye lens 15 are disposed with the respective fish-eye lenses faced with each other. An image pick-up range of the first camera 12 and an image pick-up range of the second camera 14 are partially overlapped, and only a relatively narrow area at the backside of each camera becomes a blind area. A processor 30 sets a frame F in the image pick-up area of the first camera 12 and the image pick-up area of the second camera 14 respectively corresponding to a set monitoring range. The image data within these frames F are taken out and distortions of the image due to the characteristics of the fish-eye lenses 13 and 15 are eliminated to obtain first and second transformed frame data. These transformed frame data are combined by an image combining unit 25, to obtain image data corresponding the monitoring range free from any gap. The combined image data is displayed in a monitor 8 through a PC 7.

10. A monitoring method for monitoring around, comprising:
-
a first step for picking up an image by a first camera having a fish-eye lens and for picking up an image by a second camera having a fish-eye lens and disposed opposite to said fish-eye lens of said first camera;
a second step for extracting image data of a range corresponding to a monitoring range from first image data captured by said first camera and second image data captured by said second camera respectively;
a third step for transforming said first image data and said second image data corresponding to the ranges extracted in said second step into first transformed frame data and second transformed frame data respectively;
a fourth step for generating combined image data corresponding to said monitoring range by combining said first transformed frame data and said second transformed frame data obtained in said third step; and
a fifth step for displaying in a display unit an image based on said combined image data generated in said fourth step. - View Dependent Claims (11, 12)
