Extrinsic Calibration of Camera Networks Based on Pedestrians

Sensors, 2016
In this paper, we propose a novel extrinsic calibration method for camera networks by analyzing tracks of pedestrians. First of all, we extract the center lines of walking persons by detecting their heads and feet in the camera images. We propose an easy
