We propose a new framework for automatic surveillance camera calibration by observing videos of pedestrians walking through the scene. Unlike existing methods that require accurate pedestrian detection and tracking, our method takes noisy foreground masks as input and automatically estimates the necessary intrinsic and extrinsic camera parameters using prior knowledge about the distribution of relative human heights. Our algorithm is computationally efficient enough for online parameter…

Pedestrian-Based Variational Bayesian Self-Calibration of Surveillance Cameras
TLDR
A probabilistic model is constructed that takes into account uncertainties in both the foot/head locations and the pedestrian heights, using foot-head homology and makes it possible to estimate the height of pedestrians and to obtain accurate camera parameters simultaneously.
Automatic Extrinsic Calibration of Camera Networks Based on Pedestrians
TLDR
A novel accurate and fully automatic extrinsic calibration framework for camera networks with partially overlapping views based on the analysis of pedestrian tracks without other calibration objects is proposed, which can obtain the triangulation error of a few centimeters.
Automatic Multi-Camera Extrinsic Parameter Calibration Based on Pedestrian Torsors †
TLDR
A novel, accurate and fully automatic extrinsic calibration framework for camera networks with partially overlapping views that detects human poses in the camera images and then models walking persons as vertical sticks and a novel method to calibrate the camera network by only using the top and centerline of a person when the bottom of the person is not available in heavily occluded scenes.
Automatic Calibration of Stationary Surveillance Cameras in the Wild
