1. A method for calibrating a depth-disparity mapping for a plenoptic imaging system, the method comprising:presenting one or more test objects to the plenoptic imaging system;
receiving known field positions and known depths for the test objects;
the plenoptic imaging system capturing plenoptic images of the test objects, the plenoptic images comprising multiple images of the test objects captured from different viewpoints;
calculating disparities for the test objects based on the multiple images taken from different viewpoints; and
determining a mapping between depth and disparity as a function of field position, based on the calculated disparities and the corresponding received known depths for the test objects for different known field positions of the test objects.
