On the resolution of plenoptic piv
WebPlenoptic-Particle Image Velocimetry (PIV) is a 3D velocimetry technique performed via custom cameras imbued with microlens arrays (MLA). The MLA serves to encode both spatial and parallax information of a subject into a single recorded image, allowing depth inference using as few as one plenoptic camera. Thus, plenoptic-PIV represents a … Web29 de jun. de 2016 · Light field PIV (LFPIV), or plenoptic PIV, is a single-camera 3D velocity measurement technique that employs a microlens array and a plenoptic camera …
