Snapshot: A Self-Calibration Protocol for Camera Sensor Networks

open access: yes2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006
A camera sensor network is a wireless network of cameras designed for ad-hoc deployment. The camera sensors in such a network need to be properly calibrated by determining their location, orientation, and range. This paper presents Snapshot, an automated calibration protocol that is explicitly designed and optimized for camera sensor networks. Snapshot

Sensor Localization and Camera Calibration in Distributed Camera Sensor Networks

2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006
Camera sensors constitute an information rich sensing modality with many potential applications in sensor networks. Their effectiveness in a sensor network setting however greatly relies on their ability to calibrate with respect to each other, and other sensors in the field. This paper examines node localization and camera calibration using the shared

A storage-centric camera sensor network

Proceedings of the 4th international conference on Embedded networked sensor systems, 2006
Improved energy-efficiency and storage capacity of new-generation NAND flash memory makes a compelling case for storage-centric sensor networks. Such a storage-centric sensor network emphasizes the use of platforms with larger storage and more extensive use of the storage capacities on sensors.

Automated calibration of a camera sensor network

2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005
In this paper we present a new approach for the online calibration of a camera sensor network. This is the first step towards fully exploiting the potential for collaboration between mobile robots and static sensors sharing the same network. In particular we propose an approach for extracting the 3D pose of each camera in a common reference frame, with

Camera selection in visual sensor networks

2007 IEEE Conference on Advanced Video and Signal Based Surveillance, 2007
Wireless networks of visual sensors have recently emerged as a new type of sensor-based intelligent system, with performance and complexity challenges that go beyond that of existing wireless sensor networks. The goal of the visual sensor network we examine is to provide a user with visual information from any arbitrary viewpoint within the monitored ...

Trusted Video Streams in Camera Sensor Networks

2020 IEEE 18th International Conference on Embedded and Ubiquitous Computing (EUC), 2020
Proof of integrity in produced video data by surveillance cameras requires active forensic methods such as signatures, otherwise authenticity and integrity can be comprised and data becomes unusable e. g. for legal evidence. But a simple file- or stream-signature loses its validity when the stream is cut in parts or by separating data and signature ...

Optimal camera selection for target localization in camera sensor networks

2008 42nd Annual Conference on Information Sciences and Systems, 2008
In this paper, we address the problem of localization-oriented optimal cameras selection based upon a tradeoff between the accuracy of target localization and the energy consumption in camera sensor networks. We model the addressed problem into the combined optimization problem of selecting a sequence of sets to minimize the cost while achieving a ...

Minimum camera barrier coverage in wireless camera sensor networks

2012 Proceedings IEEE INFOCOM, 2012
Barrier coverage is an important issue in wireless sensor network. In wireless camera sensor networks, the cameras take the images or videos of target objects, the position and angle of camera sensor impact on the sense range. Therefore, the barrier coverage problem in camera sensor network is different from scalar sensor network.

Reduction of sensor population in a camera sensor network

2008 International Symposium on Telecommunications, 2008
The problem of surveillance for intrusion detection in a camera sensor network is addressed in this paper. In order to save limited resources, a sensing task should involve just the right number of sensors. For a wide enough coverage area random and uniform distribution can be applied.

Demo: Mouse sensor networks, the smart camera

2011 Fifth ACM/IEEE International Conference on Distributed Smart Cameras, 2011
This paper describes an extremely low-cost smart camera with imaging sensor, freely programmable DSP, power control and wired/wireless networking capabilities. The power consumption reaches from 3mW to 240mW depending on load and transmission rates and the BOM for a single device is now 25 euros.
