MONITORING APPARATUS AND SYSTEM USING 3D INFORMATION OF IMAGES AND MONITORING METHOD USING THE SAME |
摘要 |
A monitoring apparatus using three-dimensional (3D) information of images includes: an image acquisition unit to acquire a two-dimensional (2D) image from a pan/tilt/zoom (PTZ) camera; an information extraction unit to extract 2D coordinate information of an object based on a pan/tilt angle of the PTZ camera and extract distance information between the PTZ camera and the object; an operation unit to calculate at least one of variation of the 2D coordinate information and the distance information by comparing a current frame and a previous frame of the 2D image, and variation of the 2D coordinate information and height information of the object by comparing a current frame and a previous frame of a 3D image of the object; and a position tracking unit to track a position of the object by controlling the PTZ camera based on the at least one of the two variations. |
