Metrics for designing a plenoptic imaging system

摘要

Metrics for characterizing the focusing of a plenoptic imaging system. In one aspect, the metric is based on the high frequency content and/or the blurring of the plenoptic image.

主权项

1. A computer-implemented method for automatically designing a plenoptic imaging system, comprising:
accessing a candidate design for the plenoptic imaging system, the plenoptic imaging system comprising a primary imaging subsystem, a secondary imaging array, and a location for a sensor array; simulating a plenoptic image formed by the candidate design; calculating a metric that is a function of the high frequency content in the plenoptic image; and adjusting the candidate design, based on improving the metric in a manner that increases the high frequency content in the plenoptic image; wherein adjusting the candidate design comprises adjusting a distance z2 to position the secondary imaging array at the primary image location of the primary imaging subsystem, wherein z2 is a distance between the primary imaging subsystem and the secondary imaging array, said z2 adjustment based on improving the metric in a manner that increases the high frequency content in the plenoptic image.
