Image processing system using rotatable surveillance camera
First Claim
1. An image processing system using a rotatable surveillance camera comprising:
- a surveillance camera rotatably mounted on a turntable;
an image processing apparatus; and
a camera operation section, wherein the system allows mode setting to be switched between an automatic monitoring mode for automatically monitoring an object by means of image processing and a manual operation mode that enables acquisition of a picture taken by the surveillance camera with any desired field of view by manual remote operation from the camera operation section, and the image processing apparatus in the automatic monitoring mode has a function of recognizing on a screen a plurality of reference points whose locations on a road are given, calculating orientation parameters of the surveillance camera based on the positions of the reference points on the screen, and detecting a physical quantity of the object based on a photographed image of the object using the orientation parameters.

Abstract
The disclosed image processing system detects the position and speed of a vehicle with high accuracy by accurately measuring the orientation of a rotatable surveillance camera 3 by means of image processing. This system allows mode setting to be switched between an automatic monitoring mode and a manual operation mode. When the mode is switched from the manual operation mode to the automatic monitoring mode, an image processing apparatus 7 recognizes on a screen a plurality of reference points 11 whose locations on a road are given, calculates orientation parameters of the surveillance camera 3 based on the positions of the reference points on the screen, and detects the position and speed of the vehicle based on photographed images of the vehicle using the orientation parameters, thereby detecting phenomena such as traffic congestion and accidents.
