This model is particularly suited for real-time applications, thanks to the low computational load required when the active camera is moved. In addition, a simple technique for interpolating calibration parameters is described, resulting in very accurate calibration over the full range of focal lengths. The proposed system can be employed to enhance the patrolling activity performed by a network of active cameras that supervise large areas. Experiments are also presented, showing the improvement provided over traditional pin-hole camera models. 收起
