Abstract[English]
A method comprising: introducing an object into a tube at an introduction site of the tube, wherein a liquid flows in the tube (810); capturing M images of a scene which includes a detection portion of the tube, wherein the detection portion is downstream with respect to the introduction site, and wherein M is an integer greater than 1(820); determining a time point at which the object reaches the detection portion based on at least an image of the M images (830); and determining a flow speed of the liquid in the tube based on the time point (840).[French]
L'invention concerne un procédé comprenant : l'introduction d'un objet dans un tube au niveau d'un site d'introduction du tube, un liquide s'écoulant dans le tube (810) ; la capture de M images d'une scène qui comprend une portion de détection du tube, la portion de détection étant en aval par rapport au site d'introduction, et M étant un nombre entier supérieur à 1 (820) ; la détermination d'un instant auquel l'objet atteint la portion de détection sur la base d'au moins une image des M images (830) ; et la détermination d'une vitesse d'écoulement du liquide dans le tube sur la base de l'instant (840).
