摘要: This invention presents an approach to first estimate a depth/disparity map using spectrally coded plenoptic camera, and then based on the disparity map the parallax between different spectral channels is rectified. Based on our new technique, we can reconstruct not only multispectral images but also a depth/disparity map. Moreover, the quality of reconstructed spectral images is significantly improved using our parallax rectification.

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.

摘要: The spatial resolution of captured plenoptic images is enhanced. In one aspect, the plenoptic imaging process is modeled by a pupil image function (PIF), and a PIF inversion process is applied to the captured plenoptic image to produce a better resolution estimate of the object.
