Precise Image Calibration and Alignment

Alan Chao, Sandra Berning

Abstract:	The operational application of information derived from the integration and fusion of data from multiple platforms (i.e., airborne, orbital, ground-based, and sea-based) will provide increased combat effectiveness through faster, more flexible, more precise targeting and attack, battlefield management, resource and environmental monitoring, and battle damage assessment. The effective integration/fusion of this data poses numerous technical challenges. To overcome challenges associated with the integration of imagery from multiple sources, the Precise Image Calibration and Alignment (PICA) program is developing technology to provide precise reference information to the image fusion process. Phase I of the PICA program included an assessment of state-of-the-art reference system capabilities to support multi-sensor/ multi-platform image registration and fusion. This paper will describe results of Phase I and plans for Phase II during which techniques and algorithms will be developed and demonstrated for enhancing current reference systems technology and for applying those enhancements to the image registration process. Assessment of reference systems technologies developed will be performed using such metrics as target location error, errors in detecting and discriminating targets and threats, and computational improvements in calibration, correlation, and alignment.
