Calibration of plenoptic imaging systems

摘要

Calibration for plenoptic imaging systems. The calibration preferably is performed automatically by a processor. In one approach, the processor accesses a plenoptic image captured by the plenoptic imaging system. The plenoptic image is analyzed to determine reference points for superpixels of the plenoptic imaging system, for example the centers of the superpixels. The reference points are used to determine a location of each superpixel relative to the detector array.

主权项

1. A method for calibrating a plenoptic imaging system, the plenoptic imaging system including a detector array, the plenoptic imaging system subdividing the detector array into superpixels, the method comprising a processor executing the steps of:
accessing a plenoptic image captured by the detector array of the plenoptic imaging system; analyzing the plenoptic image to determine reference points for the superpixels of the plenoptic imaging system; wherein the step of analyzing the plenoptic image comprises:
binarizing the plenoptic image; andmorphologically filtering the binarized plenoptic image; and from the reference points, determining a location of each superpixel relative to the detector array.
