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 esti...

| description | 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, the parameters
for radial and tangential distortion in the image plane and two new depth distortion parameters. In the proposed calibration we perform
a complete bundle adjustment based on a 3D calibration target. The residual of our optimization approach is three dimensional, where
the depth residual is defined by a scaled version of the inverse virtual depth difference and thus conforms well to the measured data.
Our method is evaluated based on different camera setups and shows good accuracy. For a better characterization of our approach we
evaluate the accuracy of virtual image points projected back to 3D space. |
