Title:
BLUR-CALIBRATION SYSTEM FOR ELECTRO-OPTICAL SENSORS AND METHOD USING A MOVING MULTI-FOCAL MULTI-TARGET CONSTELLATION
Document Type and Number:
WIPO Patent Application WO/2013/066457
Kind Code:
A3
Abstract:
Blur-calibration of an imaging system using a moving multi-focal multi-target constellation is described herein. The target has a known target pattern of a plurality of point-like objects with fixed relative positions in which at least one point-like object has a different focus position. In some embodiments, blur-calibration of an imaging sensor includes moving a known target pattern across the field-of view (FOV) of the imaging sensor to present the target pattern across different frames at different pixel phases. Frames of images of the moving target pattern as seen in the FOV of the imaging sensor are captured to sample point-like objects at different focus positions and generate a multi-focal image data output. The multi-focal image data output may be subsequently processed to generate data products at different focus positions from a high-resolution composite image generated from the captured frames.
