Abstract
A method and system is provided for performing high-resolution image assembly regardless of observed scene content. An imaging system, including a focal plane array and lenslet array can be calibrated to account for subimage shifts. A calibration module can determine the subimage shifts by calculating an average point source position reference point coordinates for each of the subimages, and then determining the difference between the average point source position and the reference point coordinates for each subimage. The imaging system can then be calibrated utilizing the subimage shifts for each of the plurality of subimages. Finally, an assembly module can perform a high-resolution image assembly with the calibrated imaging system.
