METHOD AND SYSTEM FOR RENDERING VISIBLE A PLUME OF DISPERSING FLUID SO AS TO REVEAL ITS SOURCE

摘要

A method for monitoring a fluid release plume (1) emitted by an industrial plant and/or an underground hydrocarbon fluid deposit into an adjacent space (3) comprises: a) monitoring the space (3) by means of a video camera during a selected period of time to generate an input video movie of the space (3); b) decomposing the generated input video movie into a series (s) of different spatial frequency bands; c) filtering the series (s) of spatial frequency bands by means of at least one temporal filter; d) amplifying the series (s) of filtered spatial frequency bands by a series of selected amplification factors (α1, α2,...-αs, wherein at least one amplification factor (α1) differs from the other amplification factors (α2,... -αs); and e) reconstructing an output video movie of the space (3) in which the fluid release plume (1) is enhanced by displaying a recomposition of the series of amplified filtered spatial frequency bands.
