Camera calibration in wireless multimedia sensor networks [PDF]
2009 International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2009 Wireless Multi-media Sensor Networks (WMSNs) have become increasingly popular in recent years, driven in part by the increasing commoditization of small, low-cost CMOS sensors. As such, the challenge of automatically calibrating these types of cameras nodes has become an important research problem, especially for the case when a large quantity of these

Distributed calibration of a camera sensor network [PDF]
2008 IEEE International Conference on Robotics and Biomimetics, 2009 Wireless camera sensor networks are finding potential applications in the areas of sensing and control. Such applications require the camera nodes of the network be calibrated precisely. This paper proposes a simple algorithm to perform distributed calibration of a camera sensor network that has been deployed in an unknown environment.
