Abstract

L'invention concerne un procédé d'inspection d'une surface, notamment d'une coque de bateau, comprenant les étapes suivantes : h) acquérir des images d'une surface à inspecter à partir d'au moins deux stations situées à des positions différentes, lesdites images ayant au moins une zone de recouvrement, i) construire en trois dimensions ladite surface à inspecter dans un repère à partir des différentes images acquises, j) visualiser ladite surface à inspecter en trois dimensions depuis l'une desdites stations et définir au moins une première zone à traiter, k) visualiser ladite première zone à traiter selon une autre desdites stations et déterminer au moins une deuxième zone à traiter, l) associer chacune desdites première et deuxième zones à traiter à au moins un coefficient de pondération de traitement, m) les superficies desdites première et deuxième zones à traiter, n) obtenir, au moins à partir desdites superficies déterminées et desdites première et deuxième zones à traiter, une superficie totale à traiter.The invention relates to a method for inspecting a surface, in particular a boat hull, comprising the following steps: h) acquiring images of a surface to be inspected from at least two stations located at positions different, said images having at least one overlapping area, i) construct in three dimensions said surface to be inspected in a frame from the different acquired images, j) view said surface to be inspected in three dimensions from one of said stations and define at least a first area to be treated, k) viewing said first area to be treated according to another of said stations and determining at least a second area to be treated, l) associating each of said first and second areas to be treated with at least one weighting coefficient of treatment, m) the areas of said first and second areas to be treated, n) obtain, at least from said determined areas and said first and second areas to be treated, a total area to be treated.
