Abstract:
1. An apparatus for acquiring a face image using multiple cameras so as to identify a human located at a remote site, comprising: a multi-camera control module for tracking an interest object being detected and tracked by a fixed camera through a Pan-Tilt-Zoom (PTZ) camera, and generating an image of the interest object; and a face-image acquisition module for acquiring a face image appropriate for identifying a face image of the remote human in the interest object image generated by the multi-camera control module, wherein the multi-camera control module includes: wherein the PTZ camera controller detects the interest object from an input image using an object characteristic value, performs zoom-in or zoom-out control according to a size of the interest object, adjusts a magnitude of pan and tilt output values in response to the zoom-in or zoom-out control, and performs the fuzzy inference through a fuzzy inference engine using center coordinates of the image and based on the magnitude of the pan and tilt output values, and wherein the PTZ camera controller controls pan, tilt, and zoom operations of the PTZ camera based on an output value of the fuzzy inference engine.
