Abstract
A collimated object is adjustable to produce collimated light propagating along different propagation directions. The plenoptic imaging system under calibration captures plenoptic images of the object adjusted to different propagation directions. The captured plenoptic images includes superpixels, each of which includes subpixels. Each subpixel captures light from a corresponding light field viewing direction. Based on the captured plenoptic images, a calibration module calculates which propagation directions map to which subpixels. The mapping defines the light field viewing directions for the subpixels. This can be used to improve processing of plenoptic images captured by the plenoptic imaging system.
