Abstract

Procédé (100) de numérotation des tubes à l’intérieur d’un échangeur de chaleur (1) d’un générateur de vapeur, ledit échangeur de chaleur (1) comprenant une plaque support (6) et une pluralité de tubes (7), chaque tube de la pluralité de tubes (7) étant monté sur la plaque support (6) transversalement à un plan formé par la plaque support (6), la pluralité de tubes (7) formant au moins un alignement, le procédé (100) comprenant les étapes suivantes : - acquisition (101), par un dispositif mobile d’acquisition d’images, d’une suite d’images, une image d’une portion (11, 12, 13, 14, 15) de chaque tube (7) de l’au moins un alignement de tubes étant comprise dans au moins une image de la suite d’images, l’acquisition (101) de la suite d’images étant réalisée au cours d’un déplacement du dispositif mobile le long de l’au moins un alignement de tubes ;- traitement (102) de la suite d’images acquises, par un moyen de traitement, pour reconnaître, et suivre chaque tube en l’identifiant dans la suite d’images acquises;- détermination (103) d’une direction de déplacement du dispositif mobile;- comptage ou décomptage (104), par le moyen de traitement, des tubes suivis et identifiés dans la suite d’images, en fonction de la direction de déplacement pour la détermination d’un numéro associé à chaque tube détecté de l’au moins un alignement de tubes. Figure 2A method (100) of numbering tubes inside a heat exchanger (1) of a steam generator, said heat exchanger (1) comprising a support plate (6) and a plurality of tubes (7) , each tube of the plurality of tubes (7) being mounted on the support plate (6) transversely to a plane formed by the support plate (6), the plurality of tubes (7) forming at least one alignment, the method (100 ) comprising the following steps: - acquisition (101), by a mobile image acquisition device, of a series of images, an image of a portion (11, 12, 13, 14, 15) of each tube (7) of the at least one alignment of tubes being included in at least one image of the series of images, the acquisition (101) of the series of images being carried out during a movement of the mobile device along the at least one alignment of tubes; - processing (102) of the sequence of acquired images, by a processing means, to recognize and track each tube by identifying it in the sequence of acquired images; - determination (103) of a direction of movement of the mobile device; - counting or down counting (104), by the processing means, of the tubes tracked and identified in the sequence of images, according to of the direction of movement for determining a number associated with each detected tube of the at least one row of tubes.
