PAN, TILT, AND ZOOM CAMERA AND METHOD FOR AIMING PTZ CAMERA

PAN, TILT, AND ZOOM CAMERA AND METHOD FOR AIMING PTZ CAMERA

A method for aiming a pan, tilt, and zoom (PTZ) camera captures a first image of a monitored area, and calculates a state vector of a predetermined object or point in the first image at one zoom setting. The state vector of the predetermined object or point is recorded in a state vector table. The m...

description A method for aiming a pan, tilt, and zoom (PTZ) camera captures a first image of a monitored area, and calculates a state vector of a predetermined object or point in the first image at one zoom setting. The state vector of the predetermined object or point is recorded in a state vector table. The method aims the PTZ camera to align a center point of the first image to a selected target point, and captures a second image of the monitored area. In order to calculate state vectors of points in the second image, N pieces of reference images related to the second image are calculated using a particle filter. After calculating a similarity between each of the N pieces of reference images and the second image, the method calculates the state vectors of the points in the second image according to each similarity, and updates the state vector table with the state vectors.
