Global Vision System - An Electronic Pan-Tilt-Zoom Camera Array

Mircea Nicolescu


We present a prototype system functionally equivalent to a mobile pan-tilt-zoom camera, which uses an array of fixed CMOS cameras instead. By performing an offline pre-calibration procedure, we create a two-dimensional mosaic of the observed scene with geometric and photometric correction. Then we are able to create any arbitrary intermediate view from the collection of images continuously acquired by the array of cameras. Compared to a standard mobile camera platform, our system provides the same functionality with similar accuracy in image quality and pan-tilt-zoom performance, but is faster, more robust and cheaper.
