    摘要： A plenoptic otoscope enables three-dimensional and/or spectral imaging of the inside of the ear to assist in improved diagnosis of inflammations and infections. The plenoptic otoscope includes a primary imaging system and a plenoptic sensor. The primary imaging system includes an otoscope objective and relay optics, which cooperate to form an image of an inside of an ear at an intermediate image plane. The plenoptic sensor includes a microimaging array positioned at the intermediate image plane and a sensor array positioned at a conjugate of the pupil plane. An optional filter module may be positioned at the pupil plane or one of its conjugates to facilitate three-dimensional and/or spectral imaging.

    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.
