Patent attributes
A camera control apparatus includes a database to store camera installation information of the cameras including a main camera and one or more sub-cameras; an image acquisition unit to acquire at least one image from the cameras; and a camera controller to convert image center coordinates of the image acquired by the main camera to three-dimensional coordinates on a three-dimensional reference coordinate system, by using the camera installation information, select at least one new main camera from among the one or more sub-cameras that include the three-dimensional coordinates as field-of-view information, and calculate a control value of the newly selected main camera for controlling the newly selected main camera to gaze the three-dimensional coordinates.
