Abstract
Provided is a surveillance camera system for controlling cameras by calculating a movement amount of the cameras based on position information and orientation information of the cameras and position information of an object being surveilled. The surveillance camera system includes: a camera receiving an image from a surveillance area; a driving device combined with the camera, wherein the driving device moves the camera; and a camera controller controlling the driving device by using initial coordinates defined with a position and an azimuth at which the camera is installed and a current direction of the camera, so that the camera faces a target position.
Claims19
A surveillance camera system comprising:
- a first surveillance unit located at a first position, the first surveillance unit comprising:
- a first camera to obtain a first image of a surveillance area;
- a first driving device combined with the first camera, the first driving device to move the first camera;
- and
- a first camera controller to control the first driving device using coordinates of a target position based on initial coordinates defined by a position and an azimuth at which the first camera is installed, and a current direction of the first camera, so that the first camera faces the target position;
- and
- an image analyzer to process the first image to identify a moving object in the surveillance area;
- wherein:
- the first camera controller is configured to determine target object coordinates in a reference coordinate system corresponding to the identified moving object;
- and
- the first surveillance unit sends the target object coordinates directly to a second surveillance unit in reference coordinate system coordinates;
- the system further comprising:
- the second surveillance unit that is located at a second position, the second surveillance unit comprising:
- a second camera to obtain a second image of the surveillance area;
- a second driving device combined with the second camera, the second driving device to move the second camera;
- a second camera controller to calculate the coordinates of the target position in camera pan and tilt coordinates based on:
- initial coordinates defined by a position and an azimuth at which the second camera is installed;
- a current direction of the second camera;
- and
- the target object coordinates in the reference coordinate system coordinates received from the first surveillance unit;
- wherein:
- each of the first camera controller and the second camera controller comprises:
- a coordinate transformer configured to transform the position of an object to be surveilled into the target position in the reference coordinate system;
- a camera selector configured to select designated surveillance units for surveilling the object to be surveilled from among a further surveillance unit and the first and second surveillance units;
- and
- a coordinate transmitter configured to transmit the target position of the object to be surveilled to the selected designated surveillance units in reference coordinate system coordinates;
- and
- the reference coordinate system is defined by a global positioning system (GPS).
