METHOD FOR CALIBRATING IMAGING DEVICE, METHOD FOR CALIBRATING IMAGING SYSTEM INCLUDING ARRANGEMENT OF IMAGING DEVICES, AND IMAGING SYSTEM

Document Type and Number:

Japanese Patent JP2007129709

Kind Code:

A

Abstract:

To perform fast imaging system calibration.

Systems and methods are disclosed for calibrating an imaging system comprising a processing unit communicatively coupled to one or more imaging devices. The imaging system may also include a display. In an embodiment, a sequence of display features are displayed on a display, and imaged by the imaging device or devices. Spatial data are compiled related to the display features and the corresponding image features. In an embodiment, the display, imaging device or devices, or both may be repositioned, another sequence of display features may be presented and the spatial data may be compiled. Using optimization and calibration techniques, the compiled spatial data may be used to obtain one or more internal imaging device parameters, one or more external parameters, or both.
