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

摘要

A method of capturing 3D data of one or more airborne particles is provided. In this method,- at least one image of the one or more airborne particles (11A,11B,11C) is taken by a plenoptic camera (1) 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 (11B) of the one or more airborne particles (11A,11B,11C) 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.
