Abstract: PURPOSE: An image detection method and a device thereof using a dual camera are provided to continuously trace a moving object by converting a coordinate value of a moving object detected in a fixed type camera into a coordinate value of a movable camera. CONSTITUTION: A monitoring region matching unit (110) extracts respective feature points from a photographed image of a fixed camera and a movable camera while controlling an angle of the movable camera. The monitoring region matching unit designates a reference location of the movable camera with respect to the fixed camera through a matching process between the extracted feature points. A coordinate conversion unit (120) converts an image coordinate of a moving object detected by the fixed camera into an image coordinate of the movable camera. A camera control unit (130) controls at least one of a pan angle, a tilt angle and a zoom magnification ratio to trace the moving object using the converted coordinate value.
