Robust Auto-Calibration from Pedestrians
2006 IEEE International Conference on Video and Signal Based Surveillance, 2006The knowledge of camera intrinsic and extrinsic parameters is useful, as it allows us to make world measurements. Unfortunately, calibration information is rarely available in video surveillance systems and it is difficult to obtain once the system is installed.

Auto-calibration by direct observation of objects
Image and Vision Computing, 1993Abstract This paper presents techniques for using objects in a scene to define the reference frames for 3D reconstruction. We first present a simple technique to calibrate an orthographic projection from four non-coplanar reference points. We then show how the observation of two additional known scene points can provide the complete perspective ...

A New Thermocouple Auto-Calibration System
2008 International Conference on Computer Science and Software Engineering, 2008According to method of the used thermocouple calibration device and the technology of virtual instrument, an auto-calibration system based on Labview is developed. It proposed the concrete design project about hardware and software, especially introduced how to realize the data processing and analysis. The practice showed that the system run well.

Auto-calibration from the orthogonality constraints
Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002This paper describes an iterative algorithm for making Euclidean reconstruction of a scene from an image sequence captured by a camera with zero skew. The output consists of both the Euclidean reconstruction and the intrinsic parameters of the camera at the different imaging instants, i.e. it also provides a camera calibration. The problem is solved in

An Auto-Calibration Method for Unattended Ground Sensors
IEEE International Conference on Acoustics Speech and Signal Processing, 2001We present an algorithm for locating and orienting a set of sensor arrays that have been deployed in a scene at unknown locations and orientation angles. This self-calibration problem is solved using a number of source signals also deployed in the scene.

Auto-Calibration of a Compound-Type Omnidirectional Camera
Digital Image Computing: Techniques and Applications (DICTA'05), 2005We propose a method for auto-calibrating a compound-type omnidirectional camera (system). This camera produces spherical panoramic image through stitching some individual images captured by several modular cameras, each of which covers a different field of view of the full viewing sphere. By auto-calibration we mean that our algorithm works online in a

Auto-calibrating surround system
The Journal of the Acoustical Society of America, 2007A multi-channel surround sound system and method is described that allows automatic and independent calibration and adjustment of the frequency, amplitude and time response of each channel of the surround sound system. The disclosed auto-calibrating surround sound (ACSS) system includes a processor that generates a test signal represented by a temporal

In this thesis, efficient methods are presented to calibrate large or small aperture array systems containing different types of uncertainties. specifically the challenge of reducing the number of external sources required to calibrate an array is addressed and array calibration methods suitable for use when sources may be operating in the "near-far ...
