Title (EN) METHOD FOR DETERMINING PRESSURE
(FR) PROCEDE DE DETERMINATION DE LA PRESSION
Abstract: front page image
(EN)A method of determining pressure requires that a three-dimensional surface of an object (14) be covered with a pressure sensitive coating. Next a raw first image (74) is acquired while the object (14) is not under test and a raw second image (74) is acquired while the object is under test. The raw first image (74) and the raw second image (74) are adjusted for a dark image (76) to form an adjusted first image and an adjusted second image. The adjusted first image and the adjusted second image are mapped (78) from a two-dimensional representation onto a three-dimensional model, to form a first model and a second model. A ratio model is formed (80) by taking the ratio of the intensity of the first model and the second model. Finally, a pressure is determined (84) for every surface that forms the three-dimensional model.
(FR)Procédé de détermination de la pression impliquant qu'une surface tridimensionnelle d'un objet (14) soit recouverte d'un revêtement sensible à la pression. On acquiert ensuite une première image brute (74) alors que l'objet (14) n'est pas encore testé et on acquiert une deuxième image brute (74) alors que l'objet est en cours de test. Les première (74) et deuxième (74) images brutes sont ajustées sur la base d'une image noire (76) pour former des première et deuxièmes images ajustées, ces dernières étant reproduites (78) à partir d'une représentation bidimensionnelle sur un modèle tridimensionnel pour former des premier et deuxième modèles. Un modèle proportionnel est formé (80) avec le rapport de l'intensité des premier et deuxième modèles. Enfin, la pression est déterminée (84) pour chaque surface formant le modèle tridimensionnel.
