Metric Calibration of a Focused Plenoptic Camera Based on a 3d Calibration Target
In this paper we present a new calibration approach for focused plenoptic cameras. We derive a new mathematical projection model of a focused plenoptic camera which considers lateral as well as depth distortion. Therefore, we derive a new depth distortion model directly from the theory of depth estimation in a focused plenoptic camera. In total the model consists of five intrinsic parameters, t...
متن کاملCalibration of Hand - held Camera Sequences for Plenoptic Modeling
In this contribution we focus on the calibration of very long image sequences from a hand-held camera that samples the viewing sphere of a scene. View sphere sampling is important for plenoptic image-based modeling approaches that try to capture the appearance o f a s c ene by storing images from all possible directions. The plenoptic approach is appealing since it allows in principle fast scen...

متن کاملStepwise calibration of focused plenoptic cameras
Monocular plenoptic cameras are slightly modified, off-the-shelf cameras that have novel capabilities as they allow for truly passive, high-resolution range sensing through a single camera lens. Commercial plenoptic cameras, however, are presently delivering range data in non-metric units, which is a barrier to novel applications e.g. in the realm of robotics. In this work we revisit the calibr...
