Abstract
A procedure to calibrate a depth-disparity mapping for a plenoptic imaging system. In one aspect, one or more test objects located at known field positions and known depths are presented to the plenoptic imaging system. The plenoptic imaging system captures plenoptic images of the test objects. The plenoptic images include multiple images of the test objects captured from different viewpoints. Disparities for the test objects are calculated based on the multiple images taken from the different viewpoints. Since the field positions and depths of the test objects are known, a mapping between depth and disparity as a function of field position can be determined.
