Patent Images

1. A monitoring apparatus comprising at least one processor to implement:

  • an image acquisition unit configured to acquire a two-dimensional (2D) image of an object which is captured by a pan/tilt/zoom (PTZ) camera;

    an information extraction unit configured to extract distance information between the PTZ camera and the object based on a zoom scale of the PTZ camera;

    an operation unit configured to calculate variation of the distance information between different frames of the 2D image, and variation of height information of the object between different frames of a 3D image of the object, the height information indicating a height of the object in a 3D space represented by the 3D image; and

    a position tracking unit configured to determine a current position of the object based on the two variations.
