Comparing Volumetric Reconstruction Algorithms for Plenoptic-PIV
نویسندگان
چکیده
A new algorithm for reconstruction of 3D particle fields from plenoptic image data is presented. The algorithm is based on the well-known technique of computational refocusing with the addition of a post reconstruction filter to remove the out of focus particles. This new algorithm is compared to the MART algorithm in terms of reconstruction quality on synthetic particle fields as well as velocity data. Preliminary results indicate that the new algorithm performs the same or better than the MART algorithm while requiring orders of magnitude less computational time.

متن کاملTomographic Reconstruction of a 3-D Flow Field Using a Plenoptic Camera
A novel 3-D, 3-C PIV technique is described, based on volume illumination and a plenoptic camera to measure a velocity field. This technique is based on light-field photography, which uses a dense microlens array mounted near a camera sensor to sample the spatial and angular distribution of light entering the camera. Tomographic algorithms (MART) are then used to reconstruct a volumetric intens...
متن کاملDepth of Field in Plenoptic Cameras
Certain new algorithms used by plenoptic cameras require focused microlens images. The range of applicability of these algorithms therefore depends on the depth of field of the relay system comprising the plenoptic camera. We analyze the relationships and tradeoffs between camera parameters and depth of field and characterize conditions for optimal refocusing, stereo, and 3D imaging.
متن کاملDetermining the phase and amplitude distortion of a wavefront using a plenoptic sensor.
We have designed a plenoptic sensor to retrieve phase and amplitude changes resulting from a laser beam's propagation through atmospheric turbulence. Compared with the commonly restricted domain of (-π,π) in phase reconstruction by interferometers, the reconstructed phase obtained by the plenoptic sensors can be continuous up to a multiple of 2π. When compared with conventional Shack-Hartmann s...
متن کاملThe influence of using different reconstruction algorithms on sensitivity of quantitative 18F-FDG-PET volumetric measures to background activity variation
Introduction: This study aims to investigate the influence of background activity variation on image quantification in differently reconstructed PET/CT images. Methods: Measurements were performed on a Discovery-690 PET/CT scanner using a custom-built NEMA-like phantom. A background activity level of 5.3 and 2.6 kBq/ml 18F-FDG were applied. Ima...
