Abstract
A method for depth of field tracking and controlling of a pet companion robot device to interact with a pet includes the steps of: locating a target pet within a field of view of the camera; drawing a minimum target rectangle around the target pet, with sides of the minimum target rectangle parallel with the corresponding sides of the field of view of the camera; locating a center point P of the minimum target rectangle. When P is located in quadrangles I and II, adjusting the pet companion robot device to the right to make P overlap with the vertical center line of the field of view of the camera; and when P is located in quadrangles III and IV, adjusting the pet companion robot device to the left to make P overlap with the vertical center line of the field of view of the camera.
