Method of and device for capturing 3D data of one or more airborne particles

摘要

Disclosed is a method of capturing 3D data of one or more airborne. At least one image of the one or more airborne particles is taken by a plenoptic camera of which the geometry and the optical properties of its optics are known, and the distance of a plane of focus with at least one selected particle of the one or more airborne particles from a defined reference location is determined by use of the captured image together with the known optical properties and the known geometry of the optics of the plenoptic camera.
